New side project, kinda Show more
In case anyone is interested, I have started work on a tiny wrapper on top of Pandas, which would add support for technical analysis and back testing of pricing strats: https://github.com/preslavrachev/pandas-ta
I have long wished for an easy way to attach various indicators as Pandas columns, by just following a simple naming convention. Pandas-TA is supposed to help with that.
NOTE: This lib is in an extremely early and ugly stage, and should serve only as a PoC for now. Feedback is always welcome
Let me do a proper #introduction. I am a genuinely curious individual, born and raised in 🇧🇬, currently living in 🇩🇪. As a software engineer, I have worked on projects spanning #gamedev, #fintech and #dataanalytics.
I hate the status quo. I am a natural-born builder and tinkerer. Programming is my way of building things, and so are reading, writing, blogging, and making music.
Last, but not least, I am a long-distance running wannabe, who dreams of running an ultra-marathon one day (a long way to go)
Server Financial Issue Show more
Today, I lost my job. In two weeks, the $25/month cost of the server will become a significant part of my expenses.
I don't want this server to die. The reality is we only have one member who posts regularly (VPG) but I am interested in what #Vegan Fedi thinks about this (if anything at all).
Please boost this so I can gauge if there's anyone beyond our local TL that may have help to lend.
Worst case scenario: I pass the torch.
I want this thing to grow!

I love that the default Emacs scratch buffer text got into Mario Golf (GBC) somehow. I wonder if this was a mis-copy-and-paste from a developer, or if it was another case of a compiler taking random memory contents and using them for padding in the ROM...
The photo on the top represents my heart’s activity during a Saturday full of physical activity - having walked more than 15 km in total. The photo below it represents a day at the job - mostly, sitting behind the laptop and solving issues. STRESS KILLS! https://preslav.me/micro/2018/09180740/
Started work on a #microblog, which will be co-hosted as part of my original blog: https://preslav.me/micro/ Not much yet, but posts and features will come one by one. For now, I need to create a workflow, which will allow me to easily post to it from my mobile phone.
Anyone ever tried to post to a #Jekyll site hosted on Github, using only an iPhone? I heard that WorkingCopy makes it easy to commit and push easily and can be included as part of Workflow/Shortucts
Can’t endorse this thread enough.
I don't know about you, but I feel really exhilarated when I cover a functionality with unit tests. In reality, we can rarely start with the tests up-front (TDD-style), or even cover a functionality with tests before a realese. Deadlines often prevail, you know. Yet, once I cover a feature with enough tests (even after the fact), it is as if a 10-ton rock is falling off my shoulders. I can finally free my head, and move on, without anticipating when the thing will crash in production.#microblog
And here is the post itself: Revisiting IntStreams in #Java 8+ https://preslav.me/2018/09/11/int-streams-in-java8/
nytimes.com belongs squarely in the #GDPRHallOfShame as it sends you to multiple external sites in order to opt out.
It also provides an opt out button which is (a) hidden and (b) doesn't include advertising cookies.
I think I've shamed them before, but wth, one more doesn't hurt.
Pandas TA worklog update Show more
I have had quite a hard time trying to compute a linear regression out of a rolling #pandas DataFrame window. I thought this would be rather easy, but as it turns out, `rolling` is a hard nut to crack when you are trying to stray off the beaten path.
I wanted to solve this with the least number of external dependencies, but it seems like i should give the `statsmodels` package a try. I found an example that seems to be working here: https://stackoverflow.com/questions/19991445/run-an-ols-regression-with-pandas-data-frame#19991632
Does anyone here still remember #BeOS? https://www.computerworld.com.au/article/646410/beta-release-nears-beos-inspired-open-source-os-haiku/ #OSS
C♯ is a good Microsoft language, but wind players prefer D♭
We're really worried that this could affect services like ActivePub/Mastodon instances, opening them up to lawsuits or requiring expensive filters.
A few thoughts on #Medium, I have been pondering on for a while: https://preslav.me/2018/09/05/medium-walled-garden/ #readmystuff #2cents
It'd be good if Mastodon had a "mute this individual post" option. Then I wouldn't have to see the same popular toot dozens of times when the people I'm following boost it.
Same goes for muting replies to a particular post you've created. You don't lose anything as you can just go back and review the toot later if you want to see how the thread continued.
