gadrevon The Secret Life of Circuits

If you're ordering from Europe, be sure to check if it's available in your local Amazon page first, I almost got slapped with like a 50% shipping/import charges because I went straight to the main link (the US amazon). The ones that have it are listed in the blog post.

gadrevon LibreOffice breaks download records after declaring it has no AI features

gadrevon Kobo can run apps now

Yes. Also from looking for device compatibility:

> Tested on one device: the Kobo Clara BW (N365, device code 391), firmware 4.45.23697. Every device write is gated on an exact match of framebuffer identity, geometry, device code, serial model prefix, firmware version and kernel release, so a different reader is refused rather than guessed at.

I can't stop reading "gated" on LLM output lately.

Anyways, I wish this worked on my Libra :<

gadrevon European ISPs Want Rightsholders Held Accountable for Overblocking Damage

It's ridiculous. Not being able to work (or having tools/certain websites fail randomly each time there's a high audience match) because "soccer" tells you a lot about the priorities of the country. Or at least of the elements that make these kinds of decisions and policies possible...

We even got an isitchristmas.com-like website to track this (https://hayahora.futbol/). I admit I find it a bit amusing.

gadrevon Did Claude increase bugs in rsync?

Nah, I skimmed TFA but then I went into the linked GH issues thread, and that's the one that scared me a bit. I just want to hold it for a while and not run into some of the things I'm reading since I'm on the latest ubuntu. Just a precaution.

I didn't have the time to actually think about any "arguments" at all tbh it's just a knee jerk reaction as I get ready to log off for the weekend. Not actually looking to argument for or against your post at all lol.

gadrevon Did Claude increase bugs in rsync?

Ok.

  $ apt-cache policy rsync | grep Installed
    Installed: 3.4.1+ds1-7ubuntu0.2
  $ sudo apt-mark hold rsync     
    rsync set on hold.

gadrevon Migrating to the EU

Yes but you may need the IPs to warm up and build some reputation, depending where you setup your server the IPs may be burned. Check logs and reputation with some of the postmaster tools the major providers offer and with the services that allow looking up an IP. senderscore used to be convenient to use now it displays a stupid contact form when you try to check an IP, there are others.

To be honest I haven't done the setup for sending a handful of emails but IPs sending hundreds/thousands per day it's fine as long as you don't start spamming people and get flagged.

gadrevon CLI tool to check the Git status of multiple projects

Been a while since I've used it, but I remember using a tool for this, gita [1], you could also just pass through commands to each repo.

gadrevon Dark mode by local sunlight (2021)

Just like sibling here, hard disagree.

I don't like all toggles to be gone since dark mode quality varies a lot, and also I may want some sites or apps one way and some another way. So removing the choice and slapping all configuration under a single "dark/light" browser toggle really annoys me, especially when sites stop providing the toggles because it's more convenient to just use the CSS property and do less. To me it's another step in the dumbing down of the UIs that I regret.

Perfectly ok with defaulting to that global setting though.

Similar vibes to the relative date infection with no option to opt out and get the full date in most sites nowadays.

gadrevon Mozilla to shut down Pocket on July 8

Pocket was very convenient to send random articles to my Kobo, which comes with a Pocket integration. Great for reading long blog posts and such, easier on the eyes. Will miss it.

gadrevon Is LinkedIn Down?

Down, accessing from EU. Got the error page with a telescope, and also another, more elaborate one about a host without DNS or something.

gadrevon Linear Algebra Done Right – 4th Edition

Gilbert Strang's course on Linear Algebra. Playlist: https://www.youtube.com/playlist?list=PL49CF3715CB9EF31D

Not as big in scope, though, but great introduction.

gadrevon E-ink is so Retropunk

I love e-ink devices.

Just back from a reading session in my Kobo, and I sent this article to it of course :) (through Firefox/Pocket). I can even read in the swimming pool (it's water resistant), nothing better than reading in sunglasses halfway in on a sunny day, awesome!!! And it doesn't weigh as much as some books. While I still prefer paper for certain reads, it has definitely helped get back into the habit of reading real books/reading more, so lost to smartphones and social media / "sugar" information type content these days. So convenient in terms of size/weight/number of books you can carry, while being easy on the eyes. No distracting crap, either, as TFA mentions.

Long live e-ink, whatever device you like most!!

gadrevon Is technical analysis just stock market astrology?

Agreed about the statistic of failure rate. For consistent profitablity it's probably at or below 2%, even if it's higher in a given year. The reason is not only lack of a strategy that doesn't depend on specific market conditions, but often (unless you're talking about algos) is psychological. Trading is psychologically very difficult.

You're right in that most of the time, the directional probability of the market is close to 50% for a 1:1 trade.

There are instances where the directional probability is significantly above 50% to make a trade have a positive EV (if it's not 1:1, the baseline is not 50%, and there are similarly moments where the directional probability for a different risk-reward is above its baseline for some direction). Different strategies tailor to different RRs, but you can absolutely find those entries.

However, as you said it's easy to get caught up in the illusion of profitability for a given market condition. For example, in a strong bull market like the post COVID stimulus, you could trade to the long side in a large timeframe and just win money because of the anomaly of such a protracted spike in the daily charts.

That's not a sustainable strategy though which explains what happened to your friends. A price action system that takes into account markets structure works in every environment, be it ranging, surging or a bear market.

Learning price action TA takes time to learn though, it's a skill like when we learned to code till the time we got paid for it. And trading, in general, goes against how our brain works. Psychology is the great barrier to profitability once you have a strategy. It explains the high failure rate. it being a hard skill is why there's so few people doing it, But it's not because it needs a very high IQ or Rafa Nadal's strength of mind. Most people could get there, but it takes a lot of effort, and theres so much deception and scamming around it, it's easier to pretend it's impossible based on the amount of people that fail.

gadrevon Is technical analysis just stock market astrology?

TA is a very broad umbrella, and forms of TA work. Day traders exploit it day after day. It doesn't require sophisticated technology or deep pockets. I see many people that necessarily aren't familiarized enough with the trading world argue otherwise, which is unfortunate since they're making categorical statements while being not very well informed.

I'm a bit blunt because of this, but you have to remember that calling "SMA crossover" TA is like calling setting up the washer "programming" it and equating it with programming in a software developer sense. And both are available to a wide population! Guys, there's much more to TA than that (and similar super simple strategies that just rely on no or very simple market structure).

I just had to reply. Someone down there said he spent time and said no indicator will reliably predict price. Forget about magical indicators, agreed. I have proved TA to myself, but it doesn't look at all like what the article or many of the comments describe. It's one TA system of many, though.

I'm happy to answer questions if anyone disagreeing has any. I may not be able to do so for a broad variety of scenarios, since I'm talking specifically about day trading, but the "patterns" (it's not just patterns, it's patterns in a market structure context where you get the alpha from, otherwise I understand the "astrology" analogy presented here) apply to longer timeframes as well.

gadrevon Is technical analysis just stock market astrology?

You're wrong in your conclusion, even though the argument looks good.

The opportunity is there for the average person to take, but it needs sufficient skill / training, like any other skill. I can't "prove it" to you, but I already proved it to myself and many people in the trading community did.

You don't need any sophisticated tools or huge amounts of money. It's bloody difficult though, not just for the technical reasons (there are many strategies but most go beyond a MA crossover, even though I'm not denying even that can produce alpha -- I don't know or care), but mostly for psychological reasons. And psychology is what's behind many of the patterns you see in the markets.

gadrevon Gilbert Strang's final lecture at MIT: May 15, 11:00am

Linear Algebra was a course in the first semester of freshman year when I was in uni (this wasn't in the US or in an english speaking country). It was famous for being a "filter" course, that made a lot of people quit the degree and switch to a different degree next year.

It had a 94% failure rate, but I got to pass on the first attempt because Gil's free lectures of his LA course made me intuitively understand the stuff we were being taught in that course, which was very dry and IMO poorly explained, at least for freshmen. Don't think I would have dodged the bullet otherwise.

Thanks Gil.

gadrevon New tool from curl creator – trurl – for URL parsing and manipulation

https://github.com/curl/trurl

Apparently, it requires curl 7.81 to compile, but I'm on ubuntu 20 (7.6x) and wanted to do a quick try, so this patch makes it work (trivially) by removing the couple of new symbols depending on that newer version. Just a quick hack to compile.

gadrevon 4th leak reported on Nord Stream pipelines in Baltic Sea

Don't you remember the US pressuring to stop NS2 earlier in the year? How can Germany NOT be a "hesitant" ally in energy matters if its enconomy depends mostly on cheap energy, being the biggest EU exporter?

gadrevon The free YouTube tier is about to become unbearable with even more ads

One possible problem is if ad blocking technologies spread enough, they will stop working because it becomes a problem big enough for YT & others, or at least the adfree experience becomes harder.

I can't explain how, and I don't really care, but it could become a cat & mouse game with the developers of uBlock, Newpipe and similar, and the big corp, in this case Google.

gadrevon Ask HN: Best beginner friendly linear algebra book?

I believe I used this back in the day when preparing the LA course at uni, A First Course in Linear Algebra: http://linear.ups.edu/download.html .

Also I'm sure it's been mentioned here already, but the MIT Linear Algebra course by Gilbert Strang was absolutely phenomenal. Really made it click for me.

gadrevon How Software Companies Die (1995) [pdf]

But...control of what? Instead of finding assembly lines of productive workers, they quickly discover that their product is produced by utterly unpredictable, uncooperative, disobedient, _and worst of all, unattractive people_ who resist all attempts at management.

I feel like this could be a line taken out of American Psycho :D.

gadrevon Show HN: Spanish Basic

You're right about sino, most likely they collapsed it for parsing purposes.

gadrevon Show HN: Spanish Basic

Agreed. I think it's a bad idea (for the stated purpose, not as a nice little project which is always good to see of course). There's already sort of a problem in spanish texts (articles, some books) where the author chooses to make up (often cringy) translations for terms that don't really have an accepted counterpart in spanish. So they just translate the thing literally, and without consistency. Each author decides what to translate and how. This is probably an issue too in other languages.

Example: "arreglo". Why would you call an array that way?

Learning a programming language is already hard enough (especially the first one) to add another axis to the process, and you'll get much less out of the experience if you are limited to a "vainilla" universe.

gadrevon Dark pattern: how YouTube makes sure you don’t always “skip ad”

But you can't "cast" from Newpipe (you'd have cast the phone's screen and play stuff in Newpipe in your phone). Which anyways is what I do when I start getting too many ads (typically I just shutdown the TV and try to time turning it back on so the ad is finishing. it's something of a mini-game).

EDIT: I'm referring to the original chromecast, not the new "Chromecast with Google TV"

gadrevon I employed a California resident, so now I’m subject to its regulations

It was a one-employee "company" (besides the founder). I don't think that qualifies as "any tech company". Just try to put yourself in the owner's shoes.
