- DIS went about +8% on tuesday and then -1 each day through the rest of the week. Decided to hold through Monday, after people lazily watched Disney+ all weekend and shared their logins, hoping for another spike. It happened. Sold everything for a total profit of $650.
- Worth reminding that I did nothing to deserve this. Got $650 for a couple clicks. I don't like the volatility or the rationale of modern investment. I've contributed nothing to the world through these actions, and I've been rewarded for it. Others have dedicated their lives to the same, becoming billionaires. The spirit of investment is the encouragement of new technologies/products/services/etc. We can do this without public trading, for it corrupts more than it enables.
- Won both fantasy games. Got 3/5 in sbsc.
- >64% across the entire league in supercontest, our highest ever in the 2018 and 2019 seasons (except week 17, garbage time).
- Tofu and tempeh are both from soy.
- Tradebot.
- Lots of work. General cleanup. Reorganized all the modules in the package structure. Moved some functions around.
- Generalized get_valid_tickers() to a simple symbol fetcher, allowing downstream functions to filter on cap/price/etc as desired.
- The reason some of the slopes were broken is that the yahoo historical data had gaps. You'd request a year, and it would only have a month, and that month might have been a great rise while the rest of the year sucked. To fix this, I changed get_slope() to only return if there is statistically significant data (at least 50% of days in the requested time period).
- There are ~1200 tickers returned by NYSE for >1b cap and <$100 price, but yahoo only has historical data on ~250 of them.
- Yahoo doesn't return consistent data. Sometimes there are gaps in history. Sometimes there are not. In a standard run for ttm perf on 1200 tickers, different symbols will report dataframe.empty in back-to-back runs.
- For this reason, I will not multiprocess the main functions in the analysis module.
- The stock market (well, NYSE) is open every day except weekends and 9 holidays, so 251 days a year (69%).
- Changed it to not filter >1B and <$100, just analyze ALL.
- Finished the entire TTM performance effort. Compared to local plots. Compared to google plots. Everything looks good.
- Finished the rankings for dividend yield. https://gitlab.com/bmahlstedt-group/tradebot/issues/5.

Sunday, November 17, 2019
- Supercontest.
- Pick percentage was sorted on for in-progress and finished games, between cover/push/noncover all complement to 100. Pick percentage was not sorted on for unstarted games. I added this as the second-to-last (num_picks, desc), before user ID.
- Made the late picks email include the recipients in the body.
- Updated the app to properly adjust for both sides of daylight savings time, which shifts in the middle of week 9: https://gitlab.com/bmahlstedt-group/supercontest/issues/139.
- The same FPS looks way worse in games than movies. In games, you produce an image and combine them all together for motion. In movies, the camera's shutter is open for a small period of time, so you get motion blur automatically.
- Bought a 12.5lb turkey. Started thawing.
- Astros have been cheating for years, banging on trash cans and whistling for offspeed pitches based on cameras.
Saturday, November 16, 2019
- Started Black Mirror from the beginning. I had only seen maybe 1-2 episodes (and the movie).
- This channel is crazy: https://www.youtube.com/user/24619carlos.
- Tradebot.
- https://gitlab.com/bmahlstedt-group/tradebot/issues/5.
- Added fetch/analysis/sort for dividend and yield %.
- Some are as high as >20%, but it's obviously dependent upon price. Some good standards are around 4-5 (verizon, ibm, etc). The securities in the S&P500 average out to about 2% right now.
- Banner. Ross 12 Remy 13 Franky 14 Art 15. Only two weeks still available.
- Only about 10% of both Portugal and Brazil speak Spanish. It's pretty similar to Portuguese tho.
- Categorization is generally good. We can lump objects into groups, and that is a convenience. It's efficient. It saves time. Those waterbreathing soap bars are fish, those large horseless cars are vans, etc.
- There's nothing wrong with this, when it's applied to objects. To companies. To Food.
- There is a problem with this, when it's applied to people, because then the group identity is considered before the individual. A stranger sees a tribe, a color, a language, before a person. It is no longer an efficient shortcut, but is instead a presumption; a presumption about something that can change, a complex human being with free will.
- This applies to good and bad judgement; I don't like X race, I am patriotic toward Y nation. They're the same presumption, the same categorization, and both ultimately become a bias surrounding an irrelevant generalization.
- Awesome warriors story: https://www.youtube.com/watch?v=fHeAHaxW0nI.
- Jim Simons is the founder of RenTech. Net worth >21b. Went to Berkeley and MIT for math.
- Mackenzie Bezos (ex-wife) is the 15th richest american at 36b, all from the divorce settlement. 4th richest woman in the world.
- Supercontest. Updated last week's single pick for Jeremy.
- select * from picks where user_id = 6 order by id desc;
- update picks set team = 'DOLPHINS' where id = 5927;
- UFC in Sao Paulo.
- Kaep did a practice workout today. Switched locations at the end, but footage should go to all 32 teams. Curious if anyone tries to pick him up, considering the underperformance of many starters right now.
- Made pistachio butter. As of right now, pecan butter is still king but I'll try a bit tomorrow after it cools/settles/separates.
Friday, November 15, 2019
- Ubuntu was busted. Power died while casting, which crashed the video cards or gpu, then the drivers (nvidia?) were trying to write to syslog and filled the entire disk (used >70GB). Booted into recovery mode (escape during startup, drop into root shell). Ran sudo apt autoremove. Then sudo rm /var/log/syslog.
- Audio devices just listed dummy output so I had to run `pulseaudio -k && sudo alsa force-reload` to get the speakers back.
- Had to run `sudo pip install py` in the system python env as well.
- Went to the getty.
- Unloaded dishwasher. Cleaned. Shaved. Haircut appointment. Thawed mouse. The usual.
- Jeop tournament of champs over. Holzhauerrrrr.
- Python 3's addition for types is only type hints. You can enforce types at runtime with other packages, like this one: https://github.com/agronholm/typeguard.
- Didn't do a huge comparison to piptools or pipenv or sx-setuptools or req-compile, but there's another hot env/req manager called poetry: https://poetry.eustace.io. Sent to Spencer.
- Mythology!
- Chaos.
- -> Gaia (Terra, Mother Earth) -> Caelus (Uranus, Father Sky).
- -> Tartarus (underworld) -> Typhon and Echidna (mother and father of all monsters) -> Cerberus, Chimera, Hydra, Sphynx.
- Charon (ferryman), Harpies, Sirens, Gorgons, and Cyclops are all basically distant cousins in this tree too.
- Titans (all kids of Gaia and Uranus).
- -> Cronus (Saturn, harvest) and Rhea (Cybele, fertility).
- Hyperion (light), Helios (sun), Selene (moon), Atlas (carries earth), Prometheus (trickster, creates man from clay, steals god fire and gives to them, etc), and Pandora.
- Olympians (all kids of Cronus and Rhea).
- -> Zeus (Jupiter, thunder) and Hera (Juno, women).
- -> Poseidon (Neptune, sea).
- -> Hades (Pluto, underworld).
- -> Hestia (Vesta, health).
- -> Demeter (Ceres, harvest).
- Gods (all downstream of Zeus).
- -> Athena (Minerva, wisdom).
- -> Dionysus (Bacchus, wine).
- -> Hephaestus (Vulcan, fire).
- -> Ares (Mars, war).
- -> Aphrodite (Venus, love/beauty, actually from Uranus' nuts in the sea lol).
- -> Hermes (Mercury, messenger) -> Pan (Faunus, shepherding).
- -> Apollo (arts/medicine).
- -> Artemis (Diana, hunting).
- -> Heracles (Hercules).
- -> Perseus (killed Medusa).
- -> 9 Muses (inspired artists).

- Supercontest.
- Made the errors in flask-user's forms render with red text.
- You can now switch your pick for a matchup. If you had already picked the opponent, it will detect that, unselect them, and pick your new team instead. https://gitlab.com/bmahlstedt-group/supercontest/issues/138.
Thursday, November 14, 2019
- Charlie Meach: https://en.wikipedia.org/wiki/Charles_L._Meach.
- Afterhours trading (these hours are for NYSE):
- Premarket: 7-930 (0400-0630 PT) (2.5hrs)
- Standard: 930-4 (0630-1300 PT) (6.5hrs)
- Postmarket: 4-8 (1300-1700 PT) (4hrs)
- Afterhours (both post and pre) are more volatile. You will see more fluctuation between price @order and price @execution.
- Smoked 10 lbs beef ribs and 10lbs pork ribs for parents and aunts/uncles.
- Added glaze column to the log
- AMZN dropped 1.4% bc Nike separated.
- ASGI (rather than WSGI) is Asynchronous Server Gateway Interface.
Wednesday, November 13, 2019
- AAPL, MSFT, GOOG, AMZN all have market caps around $1trillion.
- Supercontest banner. You can try to emulate the background-size/position/repeat with divs and imgs, but it's annoying. Usually easier to just merge the images/gifs with a separate tool (I used Kapwing today). This tech is still terrible for how advanced frontend dev has become.
- Committed new lines. Submitted picks.
- There are some interesting balk rules.
- You can't throw to an unoccupied base.
- You can't fake the throw to 1st, you have to actually throw it (just like toward home).
- You can't touch the rubber without the ball.
- If you drop the ball, it's a balk.
- The commit angle for your step is an even 45deg between home/first.
- Parents in town. Walked up to Manhattan Beach.
- DIS doing well.
- Over 10 million signups since launch yesterday.
- My 10k was up $500 by 11am. Things looking much brighter after the launch bugs yesterday.
- Up 7% at close. Continued another 1% in the first hour of afterhours.
Tuesday, November 12, 2019
- Ariel Halwani had the rock, nick diaz, stipe, francis ngannou, rose, woodley, and maia on the podcast. Wow.
- Something was wrong with nick diaz.
- Bought 69 shares of DIS in anticipation of Disney+ launch this week. Placed 136.75, executed 138.08. I'll exit fairly soon, once initial surges quell.
- Would have been positioned about $1.50 (10% less) had my damn transfer cleared a few hours earlier. It took a week in total.
- They had tech issues due to higher-than-anticipated traffic. This has both good and bad indication; good for desire/popularity, bad for ux/reputation. Overall, probably bad, or at least it will delay the rise. I'll hold.
- Went 1-1 in ff and 2.5/5 in sbsc. Exactly 50/50 week.
- Waiver moves: 3 espn 3 yahoo.
- Fresh order.
- Started The Usual Suspects but turned it off after 10 minutes. Was slow and old.
- Not really impressed with the farnam street publication either.
- Tradebot.
- Read an interesting article about how the same strategy will perform better on international stocks than US stocks, because our markets are more competitive with the biggest players.
- Each market has a unique way to win. They're not the same. This is because each market has big player(s) who focus specifically on it, and will inevitably sway with their larger weight.
- A black swan event is just an extremely rare occurrence.
- Going to just do long positions for now, due to both time and the impending decline. I'll transition to daytrading using more complex models at a later time.
- 43 companies on NYSE with a market cap >200B. 1189 with >10B.
- Wrote my current final draft. Finds all symbols >=1B market cap, with stock price <=$100, then calculates their slope over the past year via simple linear regression. It then reports the top 20, ranked.
- List this time: https://gitlab.com/bmahlstedt-group/tradebot/blob/master/2019_11_12_stocks_by_perf.txt.
- I can run this every quarter (or whatever frequency I want) and hold for a year (or whatever period) then sell.
- Closed https://gitlab.com/bmahlstedt-group/tradebot/issues/4.
- Made config, infra, and tradebot repos public. Only the services need be private.
- Ravens - Pats - Niners for power rankings: https://www.cbssports.com/nfl/powerrankings/.
- Supercontest.
- Removed the submit button. Clicking a team now selects/deselects that pick and sends it immediately to the server. https://gitlab.com/bmahlstedt-group/supercontest/issues/137.
- Holzhauer won tonight, so in the finals of the tournament of champions it's going to be him vs the woman who beat him in the regular season vs whoever wins tomorrow. Chance for redemption!
- Set up verizon wifi calling on my phone. Had to put an address in for emergency services.
Monday, November 11, 2019
- New season of rick and morty started last night.
- Popeyes chicken sandwich!
- Art's bday yesterday.
- The blue planet and planet earth shows are awesome.
- Supercontest.
- I haven't really designed the site for accessibility as much as I could have. Wonder if there are any colorblind folks who are having issue with the tables.
- Added late picks for jeremy.
- Played with the idea for user pick similarity, but ultimately didn't implement: https://gitlab.com/bmahlstedt-group/supercontest/issues/136.
- Finished mindhunter season 2.
- Unsub = unknown subject.
- Niners Seahawks MNF.
- Tradebot.
- Ran yahoo-ticker-downloader (python module) to get a csv of ALL symbols. Ran for about an hour before cancelling, it was nowhere near done. It literally just brute forces the yahoo finance rest api for every permutation of characters.
- There are 11 stock sectors: Energy, Basic Materials, Industrials, Consumer Discretionary, Consumer Staples, Healthcare, Financial, Information Technology, Communications, Utilities, Real Estate.
- Created an account with nasdaq, looked through a bit of their data.
- Rendered the rib/belly fat down for turkey injections.
- Cleaned the house, including window washing and vacuuming.
Sunday, November 10, 2019
- Supercontest.
- Made the frontend ranking only consider completed games, not in-progress or unstarted. The sorting still considers completed and in-progress, but not unstarted. Remember, the backend db scores points for all matchups, even unstarted ones, so that the client can do with the information at will.
- Derek is in LA, went up to Santa Monica.
- Bezos looking to own NFL team: https://www.cbssports.com/g00/nfl/news/amazon-founder-jeff-bezos-interested-in-owning-nfl-team-has-strong-support-among-current-owners.
- After ribs (for family visit) and turkey (for friendsgiving), I'm going to make bacon.
- Just cure a pork belly with your sodium nitrate (same as when I made pastrami beef ribs), then smoke and slice.
- I like Gitlab's transparency about competition: https://about.gitlab.com/blog/2019/11/01/devops-tool-landscape.
- Kubernetes means pilot in Greek. It was originally called Borg when it started at Google, simply a tool to manage many many distributed servers.
- A cluster has nodes (machines, physical or virtual). A node has pods (containers).
Saturday, November 9, 2019
- Merged identical google contacts. Added Savanna/Charlie/Grayson bdays to google calendar.
- Interesting, an article debunking fasted cardio: https://medium.com/@straighthealth/does-fasted-cardio-work-48fce94c2d75.
- Saw Doctor Sleep last night. Was great.
- Spaced repetition has been proven, time and time again, to be the best way to retain information and improve memory. I need to start re-reading my blog again.
- Self-hosting.
- The DO droplet is sitting comfortable at 75% mem and 70% disk.
- It's 1 shitty (v)cpu, 1GB mem, and 25GB ssd. $5/mo.
- Under any duress, this cloud server falls over and I have to restart my containers.
- For next year, as the app scales, I'll self-host. I can set up a permanent rig for <$500 with 10x the performance. It's $5/mo, or $60/yr, so if it lasts the better part of a decade I've broken even financially for a much better machine.
- Will require me to use the registrar (godaddy) for DNS, rather than DO.
- I can bring my bmahlstedt.com containers back up with the extra performance room.
- Will have to implement another monitoring solution. Basic metrics (cpu/mem/disk) and email notification. Sensu, another; there are a million.
- I can also get much better internet at my next house. No cable, no phone - just fast internet.
- Created the ticket: https://gitlab.com/bmahlstedt-group/supercontest/issues/135.
- Jcriss jits in long beach. UFC in moscow.
- Instagram gonna start hiding likes. Good. Hide followers and everything else too. Influencers need not be given a notorious platform to contribute nothing.
- Ironic that Adam Mosseri drops this news the same week as the Logan Paul and KSI 2 fight, two humans who have become famous for said trivial superficiality.
- I really should open a restaurant:

- Going to rerender the bacon and rib fat for injections on the upcoming turkeys. There's probably 16 ounces.
- Early UFC days were insane. No gloves, no weight classes, a guy wearing a gi, blows to the back of the head, hair pulling, terrible strategy, towel throwing, terrible commentary, stomping. Incredible.
Friday, November 8, 2019
- Renaissance Technologies is the most successful quant fund.
- https://www.renfund.com.
- They're ~300 employees, and are based in NY.
- Their medallion fund has the best record in investing history. It's based off Baum's models and has gotten 66% gross annualized return (39% after fees) for 30 years (88-18).
- They are a collection of scientists, not wall street buffs. They have PhDs in math/cs, not economics/finance.
- Disney jumped 5% from the earnings report, and will still have the disney+ launch next week.
- Chiro.
- Finished mindhunter season 1, starting 2.
- Real: ed kemper (the coed killer), montie rissell (the guy who wanted Big Red), benjamin barnwright (the fiance), jerry brudos (shoes), richard speck (ripe c*nts), david berkowitz (son of sam), dennis rader (btk killer, adt serviceman).
- Not real: dwight taylor (the grandma/dog killer), roger wade (principal, tickler).
- Made 5lbs maple peanut pecan butter. Tried without roasting. Definitely better roasted (and blends faster). Gonna try macademia, hazelnut, and pistachio next (individually). They're all about $1/oz, which means a batch is ~$30. Peanuts are the cheapest, then tier 2 is pecans/cashews/etc. These nuts are tier 3, most expensive.
- Hazelnuts = Filberts. Nutella is made from these.
- Ordered 2lbs of each. $100.
- Smoked 20lbs ribs. That's 43 sessions on this smoker, and it's been almost exactly a year. Almost once per week!
- Made new batch of 12 shake jars.
Thursday, November 7, 2019
- Unsubscribed from all bloomberg publications (I had maybe ~4 in daily digest). I find them redundant, half the good content is hidden behind a paywall, it's verbosely delivered in paragraphs instead of bullets, and it focuses more on politics / international affairs than tech / business / software / finance.
- Supercontest. Made the leaderboard sort the EXACT same as the all-picks, except summed over all weeks and only for completed games. Before, it didn't do the same "1 cover over 2 pushes" etc.
- Trimmed and brined 2 racks of pork spares (10lbs) and 2 racks of beef short (10lbs) for the smoker tomorrow.
- Today's music: snow patrol.
- Bud light launching their seltzer next year:
- Doctor Sleep comes out tonight, Stephen King's sequel to The Shining. It follows the son, Danny Torrance, who escaped the Overlook.
- Between IT, Castle Rock, and now this - I love how much mainstream attention King is getting. Been a fan for many years.
- datetime.fromtimestamp() should always be passed a timezone. Integers are naive, and must be made timezone-aware, otherwise it will have to assume. Some assume UTC, some assume the system-locale tz, you can never be sure. Be explicit instead.
- The UFC fight this saturday is in Russia. Zabit and Greg Hardy on the card.
- Logan Paul vs KSI 2 is also this saturday. Ugh.
- Resolved the 24 payment situation; it had reported confirmation but then rejected it weeks later. Paid for the past 2 months, ensured it was still on autopay with the card swapover. Dude at the front was nice, Joe.
- I'm liking the recent food changes:
- Oats and water raw instead of oat milk in morning shake.
- +Banana +Seeds for the morning for a more complete breakfast.
- Veggies raw in smoothie, rather than juiced. No waste.
- No more lab powders: whey, glutamine, etc. All natural: cinnamon, maca, etc.
- Remember it's much easier in python3: super().__init__()
- Tradebot.
- Finished the entire framework. Now I just need to run tests to optimize. This step is crucial. Selection is easy, but overfitting is also easy.
- Another +1 for the backtrader package. Full-featured, and very well documented.
- You can add analyzers, including final sharpe ratio reports.
- Example output from my quick sma strategy on msft for ytd:

- Wow. Look how many indicators come built-in: https://www.backtrader.com/docu/indautoref/.
- RSI = relative strength index.
- Keep in mind that every single ticker would optimize around a different strategy with different parameters. You can lump markets together with decent accuracy, but things will even then change along a chronological axis. There's no perfect approach for all situations for all time.
Wednesday, November 6, 2019
- Did some searching for spicy food challenges. Almost all are way north. None in south bay really.
- Supercontest.
- Updated the text in the payment section of the rules.
- Made the saturday email reminder 5pm, not 8pm.
- New banner. Standard wednesday deployment.
- Renamed all the files in the banner archive to include the buyer.
- New rule - you can pay incrementing $5 to take down the previous banner and put yours instead?
- Eg: Person 1 buys standard $5 banner. Person 2 hates it and pays $10 for their own banner. Person 1 gets their $5 returned. Person 3 hates them all and pays $15 for a third banner. Person 2 gets their $10 returned.
- Committed lines, submitted picks.
- Made the rankings grouped properly: https://gitlab.com/bmahlstedt-group/supercontest/issues/134.
- Abstracted the ranking cell color to a common layer, and added it back to all-picks (now that ranks are tie-grouped accurately).
- Final FF moves, got everybody except the defenses in both leagues (7/9 successful waivers).
- Upgraded the citi account in mint.
- Seaborn is a wrapper around matplotlib for visualization in python: https://seaborn.pydata.org/.
- So many people took advantage of the robinhood glitch. This is bad. All the SEC and public attention...wouldn't be surprised if they get temporarily disabled for an audit, or shut down completely as malpractice, or even long-term bankrupted due to poor reputation.
- I'd have to rewrite all my logic around another broker's API. Woohoo.
- I'd also start having to pay commission again. Woohoo.
- The glitch itself:
- With gold, robinhood gives you some margin based on the cash in your account.
- If you buy shares, and then sell them as options, robinhood would double count both in your total value, so it would allocate you more margin. That's the bug.
- You could repeat this until you had infinite money. People were posting screenshots of >1M positions, starting with 1k.
- Went to Clippers/Bucks with Harner.
- Ta-eem grill on Melrose. Mediterranean kosher. Delicious.
Tuesday, November 5, 2019
- Tradebot.
- Read a bit more about backtrader, both for general strategies and specific backtrader syntax.
- Robin-stocks has a ton of useful information. http://www.robin-stocks.com/en/latest/functions.html#getting-stock-information. Basically everything that's available about your account, holdings, and the entire public market.
- Added the full capability to transact remotely. Can login, view all account data, buy, sell, market, limit, etc. Closed the ticket. https://gitlab.com/bmahlstedt-group/tradebot/issues/2.
- Wrote the backtester components.
- Starting money.
- Quantity to buy.
- How and when to buy.
- How and when to sell.
- Commission.
- Online ingestion of yahoo finance data, current and historical.
- Reporting of portfolio performance: gross profit and % change.
- The buy/sell triggers right now are very simple, using basic analytics on the past couple days' closing price. I'm off to the indicators section next, using SMA and then more complicated models.
- A single AA battery has 2000-3000 mAh, about the same as a phone battery.
- Lost both FF games and got 1.5 in sbsc.
- The columns in the user table for email prefs were non-nullable but had no defaults, so registration was broken.
- Got a sentry error. https://sentry.io/organizations/bmahlstedt-org/issues/1315113051/?project=1773879&referrer=alert_email.
- Fixed with a sqlalchemy (clientside) default of True for all. Didn't want a server default to migrate/upgrade the tables for something so simple.
- FF moves. 4 for ESPN, 5 for Yahoo. Lotta bye weeks.
- Under armour dropped 18%, under investigation for fluffing sales numbers.
- Muse again today. Lots to go through. Solid.
- Gonna try vegan protein powder again, from peas and brown rice instead of whey isolates.
- Bought Orgain. $12/lb, similar to my standard Optimum Nutrition bin.
- More carbs (all fiber). Slightly higher fat (couple grams). Slighly lower protein (couple grams).
- Bought sesame and chia seeds.
- Apple donated 2.5B (FB and Google made similar smaller donations) to make bay area housing less insane.
- Edge is the new Microsoft browser (RIP Explorer), and it launches Jan 15. It's built off of Chromium, Google open-source Chrome. Weird.
- Transferred 10k from BOA to Robinhood for the tradebot to experiment with.
- Other options besides GTC: https://www.investopedia.com/terms/t/timeinforce.asp.
Monday, November 4, 2019
- McDonald's fired its CEO because of a relationship with an employee. Yay accountability! I've seen the exact opposite in my career.
- TikTok is owned by a Chinese company, and is undergoing a security audit because of that implication.
- New season of silicon valley started last week.
- Lewy Bodies are deposits of the alpha-synuclein protein on the brain, causing erratic dementia.
- Jeopardy tournament of champions is back, including Holzhauer.
- Quick refresher on numpy. Matrix and linear algebra functionality.
- Quick refresher on pandas. Series is 1d. Dataframe can have more dimensions. Can group, sort, reshape, statistics, all the standards you'd expect.
- Sharpe Ratio is the metric for portfolio success, adjusted for risk.
- (return - risk_free_rate) / standard deviation of excess return
- Return in excess of risk, averaged per unit of risk.
- The higher the Sharpe Ratio, the better.
- Lol stefon diggs on family feud: https://www.youtube.com/watch?v=jFJaJTXvWl0.
- Tradebot:
- Found a fantastic library for backtesting my algotrading strategies: https://www.backtrader.com/docu/quickstart/quickstart/.
- Added a col for average to the dataframe returned by get_data. Used the OHLC mean (just the avg of open, high, low, close). You can also use adjclose, or ignore open. Both are common.
- Rewrote my info fetcher to define urls with py3 fstrings.
- Linear regression with scikit-learn.
- Added the ability to plot the history with matplotlib. sudo apt install python3-tk
- Closed first ticket, as data fetching is basically complete: https://gitlab.com/bmahlstedt-group/tradebot/issues/1.
- Created new ticket for the backtesting, now that I've formulated a handful of strategies: https://gitlab.com/bmahlstedt-group/tradebot/issues/4.
- Business school applications are reducing in quantity. Good. STEM needs more.
- Ordinals, like datetime.toordinal, are integers that indicate the number of days since a specific epoch. They represent dates like YYYY-MM-DD in sortable fashion, or for regression, or for whatever else. They can be relative to the proleptic julian calendar, or proleptic gregorian, or others.
- Unix timestamps are the number of seconds that have elapsed since 1970-01-01 (midnight, the beginning of that day). Every ~31.5 million seconds is a year, so we're at about 1.5 billion.
- Listened to muse most of today.
- A cat ran on the field during the MNF game and delayed it for a couple minutes!
- P/E is great for comparing companies apples-apples, because it's normalized by share price. market value per share / earnings per share (eps). It can go negative, although this will usually just be reported as NA (losses, usually). Higher P/E is obviously more favorable for the outlook of the company.
Sunday, November 3, 2019
- UFC 244, good all around. Prelims had some great finishes. Crazy to have the BMF title fight end with doctor stoppage - he might catch some flak for that. I like masvidal, he's growing on me.
- Canelo fight, was losing but then got the knockout in the 11th.
- Love a good visual comparison between NYC and SF: https://medium.com/conquering-corporate-america/the-difference-between-living-in-new-york-and-san-francisco-3e8ae58832a5.
- Supercontest.
- DST ended. The app handled it well.
- Fixed the sort on pick percentage to properly count failures.
- The logo background-image was conflicting with the css background linear-gradient, so I have the color on the td and the team helmet on a div within the td.
- I really enjoyed the comparisons of amazon (sales %) vs kayak (pay per query), as well as orbitz (sell natively) vs kayak (redirect to sell), when doing my pharmaceutical modeling. Here's a similar comparison between Ben & Jerry's (slow) vs Amazon (fast): https://www.joelonsoftware.com/2000/05/12/strategy-letter-i-ben-and-jerrys-vs-amazon/.
- Watson had some incredible saves in his game against the jaguars this morning.
- The NFL schedule was nicely spread out this week: 1 thurs, 1 sun early, 6 sun morning, 4 sun afternoon, 1, sun night, 1 mon.

- Ufc data: https://gist.github.com/martj42/695f9a976b7beaa11617840467ac0352.

- Remember to run a bash command from ipython, just start the line with an exclamation mark.
- Tradebot.
- Added all reqs.
- Got live prices with yahoo_fin, at first. It's an extremely simple package, basically just fetching data from yahoo.
- It was only about 400 lines, and was a poorly written package (didn't even specify requirements), so I gutted and rewrote it myself. Condensed to about 100 lines. Delinted.
- Created a ticket to adjust risk based on ISM PMI later: https://gitlab.com/bmahlstedt-group/tradebot/issues/3.
- EPS = earnings per share.
- TTM= trailing 12 months.
- YOY = year over year.
- MRQ = most recent quarter.
- EBITDA = earnings before interest, tax, depreciation, and amortization.
- PEG = price/earnings-to-growth.
- Data fetch capability is complete.
- I now have a few decisions to make, as to the strategy/stance the bot uses to trade:
- Get the day's biggest losers, run regression/ML on the historical data (how far back?) for all 100 to see who is trending positive, and buy at that low. Get the day's biggest winners, and sell any you're holding at that high.
- Use analyst/earnings/stats. Decide which ones, do an instantaneous fetch, and trade based on those numbers.

- I've tried the following crutch sauces for the final hour or two, all under 250 or so to ensure any sugar content doesn't scorch:
- Honey, agave nectar, maple syrup, brown sugar (dry), bbq sauce, mustard, hot sauce.
- Honey is champ, by my own (known) preference, as well as others (blind).
- Mix it with a little more of the dry rub. Delicious.
- All of the avengers dudes (robert downey jr, ryan reynolds, paul rudd,etc) have a fantasy league for charity: https://fantasy.espn.com/football/league?leagueId=48153503.
- Sigur Ros most of today. Good background.
- Ordered some more large candles, I ran out of big coffee table / non-bedroom ones. About $1/oz is a decent average.
- Services have much better product margins than products. I love my industry.
- Disney+ launches this month. I'm very curious about that landscape, and how Netflix/HBO will perform in reaction.
- GitHub renewed its ICE contract and employees are not happy: https://www.latimes.com/business/technology/story/2019-10-31/github-ice-contract-defense. I'm not anti-microsoft, but this is good news for GitLab.
- Always like a good "useful command line tools" article, especially with screenshots: https://www.wezm.net/technical/2019/10/useful-command-line-tools.
- The supercontest app should withstand the end of daylight savings time without any issues. Everything is synced, the machines are configured to the correct timezones, and nothing is hardcoded - it's all referenced and localized in realtime. Lockdown should occur as usual, all the timestamp rerenderings should convert properly, etc.
- Sidenote - part of the reason it occurs at 2am instead of 1am (in general) is so that you avoid any day shift. If at 1am it jumped backed to midnight, there might be confusion.
- Also removed the "check in paid league" for the saturday pick reminder. It does it based on subscription now.
- Played around a little bit with 23andMe.
- Matt Stonie's halloween video yesterday was 122 pieces of candy in 30 minutes: https://www.youtube.com/watch?v=GiN8ZPMUVXY.
- This is 895g, or 2 pounds, of straight sugar.
- New batch of protein bars. Homemade peanut butter (much higher ratio of this than usual), protein powder, oats, oat milk, dates, agave nectar.
- Started mindhunter.
- Niners and Patriots 8-0, Saints and Packers 7-1, Vikings and Seahawks 6-2.
- These are the cardinal divisions:

- The NFC mostly makes sense, with the exception of the cowboys in the east.
- The AFC would mostly make sense if the colts and dolphins switched switch south/east.
- UFC245 press conference. Can't wait. 3 titles on the line. Holloway vs Volkanovski, Usman vs Covington, and Nunes vs Germaine de Randamie.
- The Rock had an announcement at the press conference. Given all the hype, I had thought it was gonna be "I'm gonna fight brock lesnar" or "I'm partnering with the UFC to have fighters on my ninja warrior show" or something meaty. It was just that his media company, Seven Bucks Productions, is gong to be making a movie about Mark Kerr (an older UFC fighter from the Mark Coleman era), and he'll be playing him.
- Elon said he's "Going offline" on Twitter.
- True:

- Worked a little bit on the tradebot.
Thursday, October 31, 2019
- Curry broke his hand last night. This is not gonna be a good year for us. Giannis missed two freethrows back to back also.
- Smoked ribs, both pork spare and beef short. Timing worked out well.
- Replenished foil, gloves, peppercorns, paprika.
- Starbucks rose 7% after all the nitro brew drinks.
- Some person with whatacan@yahoo.com created an account named Burro Ito and submitted picks for the first time this week. I assume it was one of the old players, not a completely random person. The more important note: the app handled it perfectly! They show up on the leaderboard with 0-0-0, the pick percentages are good without divide-by-zero errors, everything is smooth.
- Made the picks route not do any calculation or queries or commit scores or anything if picks were open. Just return.
- Consolidated the friendsgiving gsheet and sent it out. We're now in our 5th year, 5th signup sheet.
Wednesday, October 30, 2019
- SOC 2 is the standard for compliance criteria in data privacy. Third-party vendors and data organizations can be audited with this procedure to make sure they're not doing anything shady with the company's data. https://www.imperva.com/learn/data-security/soc-2-compliance/.
- The Cartman escape rooms is fairly new, and only ~60 teams had tried it so far. Of the 60, only 4 had escaped, and we had the fastest time of the 4!
- Damn, lockheed got a $35B order for 478 F35s.
- Fresh order. They're doing as close as 2hr delivery now.
- More terrible recorder covers. Dead.
- Supercontest.
- Made the min-width styles !important. You don't have to do the same for max-width, those are usually fluid.
- Added arrow back to lb. Made name cols wider. Widened all logo cols.
- Put a useful diverter so that the app doesn't send any emails in dev mode. This is at the very end of the chain (within supercontest.util.email.send_mail) so that you cover as much of the sequence as possible before shorting.
- Nothing is shown on the all-picks page until lockdown now.
- Completely rewrote results, passing the full data through now (covers/pushes/noncovers, for finished/inprogress/unstarted). Now the lb can show each user's record explicitly.
- The sort is updated now: in progress points, completed points, etc.
- Added faded color to the all-picks view as well (instead of header row).
- This was a pretty big update, but mostly backend. Some cool stuff for user.
- Deployed. https://gitlab.com/bmahlstedt-group/supercontest/issues/133.
- Committed lines, checked new emailer (with unsubscribe), submitted my picks.
- Remember, pure functions don't change any global state and aren't affected by any global state. They always have the same return/effect (for the same inputs).
- Lol:

- I always thought structures like NamedTuple or OrderedDict were weird collections designed for lazy programmers. If you need keys, use a dict. If you need order, use an iterable. If you need both, have one of each, not some frankenstein of both. I often keep my data in a dict and then have the sorted results as a separate definition. You're sacrificing performance by doing anything else.
- Sigur Ros for music today.
- Tried a new matcha drink today. 1000x better than the black coffee and matcha.
- Matcha, oat milk, agave, ice, blended.
- World series game 7. Great game. The nationals (a wild card!) won.
- Spotify should have a setting to filter out all the bs. Don't show me live albums, commentary albums, eps with 2 songs, acoustic albums, deluxe albums with weird filler tracks, etc. Just show me their 4 studio albums. Thanks.
- Zuckerberg has been taking a lot of heat for non fact-checking political content on fb (ads, posts, etc), which is admittedly something that very few other platforms do anyway. Twitter then came out and said it will ban all political advertising, starting on Nov 22. SHOTS.
Tuesday, October 29, 2019
- Virgin Galactic IPOed yesterday, high 12.09 low 10.50.
- Alphabet is trying to buy fitbit. Heartrate targeted ads, woohoo!
- Old Five for Fighting albums. Good memories.
- Cartman escape room!
- FF waivers. 1 for espn, 2 for yahoo.
- Considered putting the stock brake lever back on the ducati instead of the red shorty, which might be aggravating my elbow. Whyyyyyyy are hydraulic systems still used. Electronics, electronics, electronics.
- Paid rent. Maid manual citi payment since autopay doesn't activate for first billing cycle.
- Supercontest.
- Moved all the clientside pick verification to functions. Cleaned up the matchups.js quite a bit.
- Added helmets to the rollup.
- Created space between the rollup and the full picks column.
- Added right arrows for the header that shows pick counts and leaguewide percentages.
- Added percentage sign to all percentages.
- Added banner for gjm.
- Vitamix.
- Oat milk. Didn't strain it. It blends it well enough to drink, and then you can just throw out the bottom sediment when finished with the gallon. Healthier, easier, and allows you to fully mix things like dates/bananas.
- Veggie preworkout. Don't need the juicer anymore! And you get the full nutrition. No pulp mess. Higher yield. A little chunky, but I'll mess with ratios.
- Amazon fresh is now free with prime. Wow.
- Matcha arrived today. Good in the smoothies/shake. Didn't really like it straight in black coffee. Needs to be a latte or something creamy with milk.
- Put the search navbar and quick edit buttons back on my blog. Blogging about the blog. Meta.
- Bought 80 lbs of meat and rode home with it on the bike, which was crazy. 40lbs of pork spare ribs and 40lbs of beef short ribs. $210.
- World series game 6.
- Cartman escape room!
Monday, October 28, 2019
- Matcha is essentially the same green tea leaves, but instead of steeping them in hot water, they're stone-ground into a fine powder. I don't need the highest grade, since I use it for smoothies/shakes mostly.
- Ceremonial grade is for mixing with water and drinking as tea (up to $20/oz).
- Culinary grade is for stuff like smoothies, lattes, baking, etc (down to $1/oz).
- Nike CEO swap.
- 12 hours of sleep last night, uninterrupted. Yessir.
- HSBC is the bank. Hulu is owned by Disney.
- The underscore is usually the object for lodash (hehe, nice) in js.
- Joe Rogan is 52. Theo Von and Chris D'Elia are 39.
- Don't just use regular spinners, there are so many cool ones out there: https://www.react-spinners.com/.
- Awesome website, timeanddate.com.
- Supercontest.
- Just Raj, Wes, and Phil haven't paid yet.
- Greg Matthews has this week's banner.
- Changed percentages to show the first decimal place, even if it's zero. This is more consistent. The pick cells are the exception, because 0.5 scores are much rarer, so we coerce whole nums to ints.
- Strongly increased the contrast for picked/nonpicked games, making both brighter.
- Switched from rgba, where it was ~30% and ~6%.
- Now it's hex, at 50% and ~7%.
- Changed unsubmitted picks from table-info blue to orange, to make it extremely obvious that you have not submitted them.
- Removed table-active class coloring for team cells on the matchups tab. Wasn't worth much, especially conflicting with the deliberate cell coloring of the pick process, and the table-hover of bootstrap's css. Left the js to change the cursor to a hand (pointer) tho.
- Reworked the legend. Made it color-white-color again. Added the all-picks vs your-picks difference back.
- Added a template, view, form, route, and model for email preferences. Rather than tangling it in flask_user and hijacking the edit_user_profile template, I built it into a new template/backend using wtforms and flask-wtf directly (also to get more experience with these).
- Note that while wtforms has some built-in model support out of the box, there's a full-fledged pkg for it: https://wtforms-alchemy.readthedocs.io.
- Function to return all emails for users with a specific pref.
- Consolidated all email subject/body/messaging into util/email, so that the text was easy to compare and keep consistent.
- Email options are now available to the user:
- To be notified when picks open.
- To be notified when picks are about to close and they haven't picked yet.
- Colors.
- Hex.
- Hex is just like rgb, with a hex num corresponding to each color channel in red, green and blue. 0 is none, f is full, as you'd expect from hex. So 00f is fully blue. #ff0 is yellow (red and green).
- It's easy to remember from this: 000, with no color at all, is black. fff, the combination of all colors, is white.
- While you can get many colors with 3-digit hex, you can get MUCH more with 6 digit hex (which is the standard nowadays). Each of the standard 3-digit hex colors gets 16 more levels of resolution before moving on to the next one (obviously).
- 3 digit hex = 3 digits of 2^4 = 3 digits of 16 = rgb(R, G, B) where each value is a number from 0-15.
- 6 digit hex = rgb() where each digit is 0-255 (16*16, or 2^8).
- Alpha.
- The A in rgba stands for alpha. The alpha channel is what determines opacity.
- This exists for hex colors too, but only recently with CSS4. The first 6 digits are the color, and the last two digits are for alpha. Similar to rgba: 00 is fully transparent and ff is fully opaque.
- Bootstrap.
- Color ref:
- primary:
#007bff secondary: #6c757d success :#28a745 info: #17a2b8 - warning:
#ffc107 danger :#dc3545 light: #f8f9fa dark :#343a40 - The bg-<> colors are these, with full opacity. The table-<> are the same colors, but with reduced opacity (alpha ~33%).
- Raw beef/pork meat is pink because of myoglobin. When myoglobin is heated up (cooked), it turns brown. When you burn wood (and charcoal, which is already-burnt wood), it produces nitrogen dioxide. This reacts with the myoglobin as it penetrates the meat, creating a stable molecule that doesn't turn brown as it increases temperature. Curing salt (sodium nitrate) does the same thing.
- The pink doesn't change any flavor itself, it just indicates that meat has been cooked slowly enough to not rise in temp before the wood smoke has penetrated a bit, which means you're going to get smoke flavor inside the meat.
Sunday, October 27, 2019
- Supercontest.
- Email reminder worked well last night.
- Submitted about 5 sets of late picks.
- Tie coloring on all-picks was working but not on your-picks. It was comparing team name to coverer correctly, but then team name to PUSH instead of coverer to PUSH.
- Reduced the unpick opacity from 0.3 to 0.2.
- All the new coloring changes worked.
- Did a little research on the flask-user form customization for email preferences.
- Started implementing https://gitlab.com/bmahlstedt-group/supercontest/issues/130.
- Lawrence's bday last night on la tuna was great.
- Venice all day, smoking ribs with Harner's neighbor.
- 1-1 in ff. 1-4 in sbsc.
Saturday, October 26, 2019
- Git repo with the history (amendments) of the constitution: https://github.com/JesseKPhillips/USA-Constitution.
- Remember that Instagram is mostly python, and is one of the biggest scale python implementations across the globe.
- {{ form.hidden_tag() }} tells flask-wtf to use csrf.
- When flask-user templates iterate over the form variable that's made available to jinja, it's just a class passed through the route. The class is just a child of flask_wtf.FlaskForm, and it lists the fields and information about them. You can also define validations here. Example: https://github.com/lingthio/Flask-User/blob/master/flask_user/forms.py#L139.
- The robinhood sell orders completed and the funds settled, so I initiated the withdrawal to boa today.
- Supercontest.
- Updating some basic flask-user structure. Removed the bootstrap_is_hidden_field.
- Changed to proper colgroups for styling whole cols instead of each row, for the min-width in the legends and the matchup borders on all-picks.
- Played with linear and radial gradients for cell coloring. Ultimately went with diagonal stripes for all in-progress games.
- Games that were not picked still have their results show, just at 30% opacity.
- Removed the table stripes. We're doing so much with background color already. This added unwanted contrast.
- Because of bootstrap's table-responsive, min and max width won't work as desired if set on colgroups, even with !important. You have to set it on the cells directly themselves.
- There are many places where some of your intended behavior fights with styles that bootstrap is setting underneath the classes you use. Overall, still very worth it.
- Demian Maia choked out Askren.
Friday, October 25, 2019
- New season of castle rock. This one follows annie wilkes, the bipolar nurse from misery who killed the author.
- House of Spirits was cool, but the most shocking part was the SURPRISE full nudity. They didn't even warn us.
- Riding 100 down the freeway, on the ducati, in the purple suit.
- Router/modem are overheating in the cabinet, gonna leave the door open.
- Talked with bmanning about matlab/c bindings. They have a product called Coder. Functional verification still needs to happen obv, but syntax conversion is automatic.
- Music.
- Kanye released a new gospel album today? It's called JESUS IS KING. It's garbage.
- Old creed. Great. Old eve6. Not as much. Old rob thomas. Not as much. Vertical horizon was pretty good. David Gray and Howie Day. Meh. A little too soft but ok for background I guess.
- Supercontest.
- Fixed the consistent-width cols on all-picks. The logos in the headers had removed min-width.
- Distinguished the finished games from in-progress games by color stripes, not border. If the game is finished, it's the solid color representing the result. If the game is still underway, it's the same color but a white band in the middle. Looks really good.
- Made the legend look a little better, touches on both sides and white bg / black text in the middle.
- Combined both instructions/legend buttons, on all views, into one single help collapse.
- Converted all my inline styling to custom classes. Some basic ones already existed in bootstrap:
- white-space: nowrap -> text-nowrap
- rgb(225, 225, 225) -> text-muted
- display: none -> d-none
- Went through and checked for any inline scripting as well, and handled it.
- Did not minify or bundle the css. It's only like 50 lines.
- Scraped all templates for common macros I could abstract out.
- Scraped all js for common functions I could abstract out. The biggest one was colorPickCell, which contains the logic for checking game status and coverer and stuff to determine how to color the cell, red/green/yellow, and the in-progress band. This included two other helpful functions isGameUnstarted and isGameFinished.
- Used the vitamix for the first time today. It makes a whole world of difference. So satisfied, shoulda bought it years ago.
- TSLA jumped over 10% today. BTC over 40% too (so dumb).
- Shorting kinda defeats the purpose of investment, ya? Tribute to the fact that the market is really there for gamblers, not for supporting good ideas financially.
- Warriors got killed by the Clippers, but it's game 1 and the Clippers are champion contenders.
- Amazon's switch from 2 to 1 day shipping increased revenue by 24% but increased shipping costs by 46% also.
- Bootstrap source css, 10,000 lines: https://github.com/twbs/bootstrap/blob/master/dist/css/bootstrap.css.
Thursday, October 24, 2019
- Record for lines.
- Biggest all time: 27, Steelers over Bucs, 1976.
- Biggest recently: 26.5, Broncos over Jags, 2013.
- Biggest since my app: 22.5, Pats over Jets, 2019.
- Westgate.
- Leaderboard.
- After week 6, the #1 had 27/30 points (90%).
- After week 7, the #1 had 28/35 points (80%).
- They have a mobile app. Downloaded and played with it.
- Called "Fantasy Supercontest" from BookieLab Inc.
- Mine is better:
- All-time stats.
- Desktop and mobile (via browser, but responsive).
- Data API (graphql for web client and python pkg for desktop client).
- Customizable banner.
- Funny feedback form (trivial).
- Localized time.
- In-app rules, page-specific instructions, legend.
- Progress graph (total points vs week).
- Free league.
- Theirs is better:
- Native mobile.
- Full record, covers-pushes-noncovers (mine just has total points).
- Ranking graph (lb position vs week).
- Both have:
- Old seasons, old weeks (historical data).
- Leaderboard. Full percentage.
- Total picks per team per week.
- Weekly summary of teams and players.
- Team logos.
- Not sure:
- Live-update frequency.
- Administration.
- Payment interface.
- Email reminders / notifications.
- Nationals are up 2-0 in the world series.
- Listened to mostly Myles Kennedy (vocals/guitar for altar bridge) and his solo work. Tremonti is still my favorite of the 3, between Tremonti, Cornell, and Kennedy.
- Supercontest.
- Fixed a few small issues due to lowercasing the team names and mapping the statuses. The capilization now is completely confined to the frontend html, through a jinja filter. The backend python/postgres all used uppercase before, but the frontend js does now as well.
- picks_open is now forwarded to js.
- Added logos: https://gitlab.com/bmahlstedt-group/supercontest/issues/128.
- Total size of all 32 logos is 452K in vcs, which is fine.
- A deployment failed because the droplet ran out of disk space (it's 25GB).
- Decided not to do full record (covers-pushes-noncovers). I only pass total points everywhere, I don't plumb which points came from a full cover vs half point from push. It would require some surgery to expose that through the whole chain, and it doesn't add much.
- Backend did all the same pick verifications as frontend except "you picked the opponent" - added it.
- "Ethanol cannot be concentrated by ordinary distillation to greater than 97.2% by volume (95.6% by weight), because at that concentration, the vapor has the same ratio of water to alcohol as the liquid, a phenomenon known as azeotropy."
- Tesla jumped quite a bit after the profit report.
- FB won't move forward with Libra until approved by regulators (sure).
- Google possibly spied on its own employees? https://www.bloomberg.com/news/articles/2019-10-23/google-accused-of-creating-spy-tool-to-squelch-worker-dissent.
- House of Spirits event.
Wednesday, October 23, 2019
- Pulled out of every private investment. Nothing in robinhood, tradeking, or ally. All solium. I'll rediversify again after tradebot reports conclusively successful movements, hopefully after some recession with lower positions.
- There are ~630,000 publicly traded companies in the world. From a data standpoint, it's not ridiculous to do a simple linear regression on all of them through history, with decent resolution.
- Most mobile phones are in the ballpark of 375x800, for design reference (banners etc).
- Made the banner for franky. Deployed.
- Pxlr free online to remove the necessary sections, then intentionally filled in the background white so that the space between the repeated image (bg-secondary) was contrasted.
- Used background-repeat: space, which is much better because it will adjust the x padding between the repetitions responsively for viewport size.
- Background-position: center, just for the case where there's only one instance (mobile).
- And then background-size: contain, with a fixed height as usual.
- Reinstalled gnome-system-monitor for process and resource utilization, uninstalled htop. I already have top for terminal inspection, I want history with my graphical monitor (even if it's only 60 seconds).
- Clippers beat Lakers on opening night.
- Nationals beat Astros for game 1 of the world series.
- Remember:
- sudo apt remove <> will uninstall the package, and the packages that depend on it, but leave the config files.
- sudo apt purge <> will uninstall the package, and the packages that depend on it, and remove the config files.
- sudo apt autoremove will uninstall all packages that were installed as dependencies but the parents aren't around anymore. It's not the best practice to run this.
- sudo apt list --installed
- You shouldn't delete the default ubuntu python installation, there are many system packages that depend on it:
- apparmor* apport* apport-gtk* aptdaemon* apturl* apturl-common* dh-python* foomatic-db-compressed-ppds* gdm3* gedit* gedit-common* gir1.2-ibus-1.0* gnome-control-center* gnome-menus* gnome-online-accounts* gnome-session* gnome-shell* gnome-software* gnome-software-plugin-snap* gnome-terminal* gnome-tweaks* google-chrome-stable* hplip* hplip-data* ibus* ipython3* language-selector-common* language-selector-gnome* lsb-release* nautilus-extension-gnome-terminal* nautilus-share* openprinting-ppds* orca* plymouth-theme-ubuntu-text* printer-driver-foo2zjs* printer-driver-foo2zjs-common* printer-driver-m2300w* printer-driver-postscript-hp* printer-driver-ptouch* printer-driver-pxljr* system-config-printer-common* system-config-printer-udev* tox* ubuntu-drivers-common* ubuntu-release-upgrader-core* ubuntu-release-upgrader-gtk* ubuntu-session* ubuntu-software* ubuntu-system-service* unattended-upgrades* update-manager* update-manager-core* update-notifier* update-notifier-common* usb-creator-common* virtualbox* virtualbox-qt* virtualenv* xdot* xorg* xserver-xorg*
- This is absolutely ridiculous. Python should not be this coupled to the base dist and desktop env.
- Git LFS.
- My pip install was being weird after using lfs. It can't install any pip packages, which means it can't create venvs, run tests, etc. Even after uninstalling git-lfs, it was still pointing at their repo. The default index was still being reported as pypi.
- Deleted this shitty piece of code. It was messing with a bunch of system-level config on my machine. Wiped my python installation as well.
- Removed the .git/hooks/ relevant files: post-checkout, post-commit, pre-push, post-merge.
- https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh.
- Honestly fuck this project. It messed with so much in my system level. It left cruft everywhere with no mechanism for cleanup.
- Tried purge, reinstalling, more for all versions of python, pythonX-pip, virtualenv, pip, etc.
- `curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3` was the start.
- /usr/share/python-wheels is not necessary. It can be empty.
- sudo pip3 uninstall then install virtualenv tox back into the system environment was the fix.
- Joe Rogan got Edward Snowden on the podcast!
- lol:

- Snowden found no evidence of aliens, chemtrails, other gov't coverups, and conspiracy theories, and he had deep access to nearly everything.
- It was basically Snowden talking for 3 hours. Joe was probably the quietest I've ever seen.
- It's scary to live in a world where someone is prosecuted for doing the right thing.
- Departments don't collaborate, they try to work solo to take full credit for accomplishments, just like in a regular job.
- Ultimately, it's just people trying to save their jobs and/or get promotions, just like any other industry. It's just in government, politics, and intelligence.
- WeWork's CEO Adam Neumann is walking away with 1.7B after the buyout, after driving the company and the stock price into the ground. The employees are getting screwed.
- Toggle buttons are better than checkboxes, if there are many items: https://medium.com/@uxmovement/why-toggle-tokens-are-a-better-alternative-to-checkboxes-2b6403e140ff.
- Roasted 5 pounds of peanuts and processed into peanut butter.
- Listened to Chris Cornell most of today (lead singer audioslave, soundgarden). I don't like his solo work as much as Tremonti.
- Reinstalling ansible added python2.7 back to my system. Lol.
- Supercontest.
- https://gitlab.com/bmahlstedt-group/supercontest/issues/127.
- Took the plots that had complementary data (cover/push/noncover by team, and favorite/push/underdog by line) and stacked them all onto the same bar chart (for each complement to 100).
- Plotly is smart enough to sort each individual trace, and then reassign each trace based on similar label. However, if you want to sort across multiple numbers (like primary sort covers then secondary sort on covers+pushes), you should separate the full dataset separately and then build the traces explicitly, rather than having plotly aggregate for you.
- Made them horizontal and colored them with the same colors as table-success/warning/danger, for consistency.
- Committed nellw lines for week 8.
- All text looked good, appropriate relative to picks open/closed, padding, margin, during all phases of line commit.
- Submitted my picks.

- Set up the splunk logging composition, for the most part, and then removed it.
- Docker has logger drivers which tell it how to access the logs from the containers. The default is json-file.
- Splunk uses HTTP Event Collection as the logging driver, known as HEC.
- You can run 500Mb/day through Splunk for free.
- Created an account with splunk.com.
- Remember that it takes a minute or two for the splunk server to start. Check for status: healthy in docker-compose ps.
- Added a token that the app container uses to push the http events to a specific url.
- Installed the docker monitoring app inside the splunk interface.
- You need collectord to make it work, you can't just forward it directly from hec. https://www.outcoldsolutions.com/.
- This is way more complicated than it needs to be. I literally just want to tail a logfile from the browser. The docker interface already forwards stdout/stderr from the container.
- I also don't want to bloat the under-resourced DO droplet with a splunkenterprise container. It's built to do way more than I'd use it for.
- Darnold had a passer rating of 3.6 last night. Insanely low. Patriots D are absolutely killing it, they're in the top 10 for all offensive players in fantasy. I lost the yahoo league and won the espn league. Got 2/5 in supercontest.
- In purging some docker images/containers on my laptop, it tried to upgrade the database container to 12 on a new build/pull. That version is incompatible with a db created with 11 (my version), so I pinned it in docker-compose.
- Big Mouth roles I didn't know: John Mulaney is Andrew, Chelsea Peretti is Nick's phone, Kristen Bell is Jay's pillow, and Jordan Peele is Duke Ellington!
- Did blender research.
- Notes.
- I don't need pulse. I only need it for smoothies (and maybe nut butters), I don't use the blender for salsa, grinding herbs, chopping nuts, etc. Plus I still have the ninja if need be.
- I don't need preprogrammed settings. Soups, desserts, smoothies, blah.
- I don't need digital or touch control. Buttons/switches are fine.
- I don't need self-detect and self-clean. Manual control is fine.
- I don't need timers and programmability. It's not an oven.
- I don't need an app to pair with it wirelessly (lol).
- Vitamix.
- Given all the above, the 5200 is the right fit.
- There are a couple more features to consider.
- The classic series blenders have 2hp motors, while the smart series blenders have 2.2hp motors.
- The smart series blenders are a bit smaller (low profile 64oz container).
- The smart series blenders are a bit quieter.
- Those 3 features aren't worth it to me.
- Its usual price is $450, there was one available for $400. The base is red, but worth the $50 discount. Ordered.
- Camelcamelcamel is a great price tracker for buying expensive items on amazon. You can see the most/least expensive it has been, and even set up alerts where it will email you.
- Bought a huge batch of shelled, skinned, blanched, unsalted peanuts. They're much cheaper in bulk than other nuts - down as low as $2/lb. I bought 10lbs at $3/lb. At costco, the packages of pecans/cashews/etc are $8/lb, and that's a great price already.
- Downloaded paypal for my phone.
- Greg bought week 9 for the sbsc banner. Franky has week 8. Jcriss paid but still needs to send the graphic, so he'll probably get week 10.
- Netflix issued 2b of corporate bonds to fund new content, adding debt.
- WeWork is in a bad place.
- FF waivers. 3 for yahoo, 2 for espn.
- Used the new razor. Cleanup was easy, since it catches all the hair. Cleaning the unit is easy, just run under the tap (full or taken apart). It's a close shave. I need to get used to the motion/pressure so it gets everything.
- Updated the banner_archive (.gitignored):

- Made the static/README.md always show build status successful for the stack view, since the gitlab project is private. The regular readme still points to the actual build badge, updating in realtime.
- Started the new season (9) of AHS. It's called 1984, and it's an 80s camp horror theme (which I'm a big fan of).
- Would be nice if spotify had a simple feature like "save for later" where you could add artists (or albums, or songs) to a list to go through whenever you wanted. I often find a few new artists, and then find a couple more good suggestions in "related artists", but there's no way to keep those artists queued in the app to go through later.
- My laptop battery:


- Discharge, normal use, full brightness: ~12.5%/hr. Total time ~8hrs. Linear.
- Discharge, idle, closed: ~0.25%/hr. ~2% over 8hrs. Linear.
- Charge, normal use, full brightness: ~50%/hr during the linear portion to ~85%SOC. Total time ~3hrs. Logarithmic toward the end.
- Google Keep can do bulleted lists by default, just type an asterisk then space on a new line.
- Moved a few longer term items from blogger to google keep.
- The new batch of protein bars is even better than the previous, which is saying a lot.
- Made all my gitlab projects private, and transferred them all from my user namespace to my group namespace. Updated all remotes, on my laptop and the droplet.
- Updated the readme in the fivesquared project to shrink the images to a reasonable size. They now display side-by-side.
- Al Noor lunch with Corey/Harner.
- Tradebot.
- Created and configured the repository in gitlab.
- Enabled autodevops at first to play with it. It created a pipeline with 3 jobs: build, code_quality, and test. If would have added a deployment job as well, but you need a kubernetes cluster. The first job, build, failed and stopped. The default command was `herokuish buildpack build`. I don't need autodevops for this project, so I disabled it.
- Added a very basic .gitlab-ci.yml pipeline instead. Just runs pylint via tox.
- Created both tickets, one for analysis and the other for buy/sell.
- Useful advice: when performing any sort of corrective action (filing a complaint, etc) against a party in a non-face-to-face manner, pretend you're a third-party witness. You won't be discounted as disgruntled, and they'll perceive more weight around the incident if it's apparently large enough to be reported by a witness.
- LFS for prod db backups and the banner archive.
- curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
- sudo apt-get install git-lfs=2.9.0
- cd ~/code/supercontest
- git lfs install
- git lfs track "backups/"
- git lfs track "supercontest/static/img/banner_archive/"
- git add .gitattributes
- Then commit and push as usual.
- You can run `git lfs status` to see which files are going to git and which are going to lfs.
- Added the sbsc production db backups to git lfs. Added the banner_archive as well.
- Listened to some good old Tremonti solo work today. Lead vocals/guitar for creed/alterbridge.
- GitLab has template files for .gitignore, .gitlab-ci.yml, LICENSE, and Dockerfile that you can add to any project. Example: https://gitlab.com/bmahlstedt-group/tradebot/new/master. They will come prepopulated with whatever environment syntax you want (Python, for most my cases).
- Ducati is owned by Lamborghini, which is owned by Audi, which is owned by Volkswagen.
- Went through some different lists of folks' "stocks you'll never sell". Curated them into ones I actually cared about. Removed ones that didn't look amazing (unless your basis was 10 years ago). Removed the ones that I don't believe in (general electric GE, etc). Removed the ones that I don't want to support (mcdonalds MCD, etc). The remainder is obvious. The big players with consistently linear positive trends. After some recession to reduce the position, these would be good ones to dump some excess into (or weight more highly in the tradebot, as a qualitative boost since it's a quantitative tool).
