> Key to optimizing it was having a database that supported different compression strategies based on the data.

I keep wondering why automatic detection of a compression strategy is hardly ever used. Different algorithms are just better at different things.

I thought timsort was one of the few things that does this, but a quick look at Wikipedia actually indicates that I misremember. With that gone, off the top of my head I cannot think of any utility or library that does this sort of thing. It doesn't seem hard to just take a few kilobytes of data, try a handful of good algorithms, pick the best one, and repeat after a few megabytes. I imagine the gains should be double digit percentages for at least a fifth of the datasets out there, without necessarily losing out on (de)compression speed. Curious if anyone ever looked into this, though some uncertainty will always be about bias in the dataset selection.

E.g. 9 out of 10 times xz is clearly better than bzip2 (both at max compression setting), but then sometimes bzip2 actually beats xz with some margin. I don't know when or why, but it has me trying both options whenever I care about the final compressed size. I've also had that a lower level of gzip actually compressed better (I think it was -8 vs -9, but it also have been between -1 and -3 or so).
You can find it by Googling around, but you won't find it on chemistry YouTube channels as YouTube cracked down hard on those. Even videos on making precursors to RDX or HMX (which can be used to make C-4) are banned.
Ask HN: Self-taught roadmap to multiple big tech offers in a few years?
This question might've been asked a few times here, but I've added my personal spin to help be more specific.

This is not a "I want to become a career developer after many years in an unrelated career" situation. This is "I tried building my dev career for 10 years and want to (almost completely) start over".

I have held multiple jobs as a contract web developer, doing sporadic PHP and Ruby work. While I'm not exactly a stranger to cubicles and meeting rooms, my position as a temp worker really doesn't allow me to grow or make very meaningful contributions to a company.

In addition, I don't get compensated well for an engineer (US citizen for context). Most I've made in a single year is $55k gross in a MCOL area. Almost all is 1099 work

Back to the problem I want to figure out, I know I have a difficult road ahead, what with 2.5 years unemployment and sporadic contract work. Over a thousand job applications and zero offers. I have no interest in trying to run a business. My priority is financial stability (never had 401k or company health insurance) and having a more "mainstream" software engineer career.

(I'll also need to rebuild my network almost from scratch as my former colleagues do not reply to my inquiries about jobs anymore. It's kind of difficult with lockdowns still putting IRL meetups on hold, but I'm part of a few tech professional chat groups.)

The usual route for a CS student is to maintain good grades, participate in research, academic publishing and extracurriculars to help them get good internships, and one of them may convert to a FT job, all in a few years.

I am trying to construct a similar "self-taught" version plan of that. Take those gradual steps over a span of 2-3 years. Complete some similar bodies of work that gets the large companies want to interview me, and hopefully get a couple offers lined up.

I'm not asking for shortcuts. I just want to expand my options beyond just doing interview prep and digging into my network, which after 2 years without a single "yes", feels like I'm beating a dead horse.

>not enough games like, I dunno, Sayonara Wild Hearts or Celeste.

It's funny you mention Celeste, as I've not met a single woman who got into it. And honestly, it makes sense if you think about it for a second. Adding a female protagonist to a technical platformer won't automatically give it strong appeal in the female demographic.

Nor does the fact that The Sims, Stardew Valley and Bejeweled were created by men take away from the fact that they're extremely appealing to women.

I guess just part of me is always skeptical of activists ham-fistedly making design decisions, as it tends to lead to products that consumers either actively hate or don't care about.

Yeah, I can easily imagine a 90th percentile user in North America is worth closer to $100 per month. Which answers the OP’s question.

And its likely a Pareto curve too.

So a 99th percentile user could be worth $1000 per month, 99.9th percentile worth $10000 per month, etc.

I imagine they would only take the risk to offer such a premium service when they can figure out how to get everyone to upload their payslips and bank account statements.

Sometimes the mods fix the redirect, so perhaps it was different initially. But it's strange that they didn't post a comment about the change.
No surprise. Uncovering this dependency graph at a granular level is a holy grail of industry analysts because it drives the dynamics of the sector. Definitely a non-trivial task as many companies view their supply chain as a major competitive advantage and would heavily lobby to avoid having to make meaningful disclosures.
Agreed, I have pretty bad social anxiety with hypervigilance. Taking on average 3 5mg (occasionally a 10mg dose) tablets a week when needed for presentations or meetings with more weight allows me to keep my job.

Even such a small dose I feel restores a sense of normality that I haven't experienced in over 10 years without them, I'm able to rationalise what I want to say, conversation flows, I feel in control. With all that said, I've been doing this for a while and have never come close to addiction and no noticeable side effects. I continue to work on the underlying causes but without them I would be much worse off.
Yeah. Asthma is treated with beta-2 agonists. Newer beta blockers such as metoprolol are beta-1 selective and so have "almost no effect" on beta-2 receptors. Older beta blockers like propranolol are not selective at all.

Not interested in taking unnecessary risks either since there are better and safer drugs for general anxiety disorder.
The thing with most addictions is that as long as you are taking a substance and don't try to stop you feel that you are in control. As long as you have not tried to stop you will never know
On the bright side, has anyone else ever considered what an amazing amount of information there must be for mouse vets?
They also left out a another key point. Trumps renegotiation of NAFTA into USMCA created significant restrictions on importing formula from Canada.

> Absurdly, provisions were added to the United States‐ Mexico‐ Canada Agreement (USMCA) to restrict imports of formula from Canada, supposedly because China was investing in a baby food plant in Ontario, and this new production might eventually enter the U.S. market (heaven forbid!). [1]

If they can’t find a way to host it in Ukraine (I think they, and the rest of Europe, will try very very hard to make that happen, and should!!) I wouldn’t be surprised to see it hosted in Poland as their closest neighbour and supporter. Alternatively the UK as a major funder of the event (we get a weird free pass to the final due to significantly funding it) and coming second place, I could see us taking it if no other option is found.

Agreed, there will always be scammers out there. Trust the code, not the human shills. Just as with a company, consider who has controlling interest. One advantage of crypto however is that the books are wide open to those willing to look.
An alternative viewpoint is that the issue is not so much the right system of ethics as having a sense of proportion.

It sounds like you are in favor of that, but then your first two examples (Amazon vs the Caymans) are confusing - what is so palpably evil about the latter? Also, surely most giant corporations are not legally in the Cayman islands, but Delaware, right?
There does seem to be some genetic variability at play here. I've known people who were able to quit a benzo cold turkey after taking it for significantly longer than a week.

It's very interesting because it predates the modern consensus that hacker movie music should be electronic. If it were made today it would be full of synths, but back then nobody knew what a hacker movie was supposed to sound like. So you get lots of choir vocals, strings, and piano. It's beautiful!
Postgres or MySQL on a free tier VM will be fine for this use case. With one paid VM, you could easily get to something ridiculous, like 1M TPS.

If you get past that, you could add memcache to the read path.

If you need more than 1M button pushes per second, each frontend server could see if the timer was reset less than a second ago.

At this point, you're limited by data center bandwidth. You could move the frontend servers into edge infrastructure.

That should scale linearly to billions of requests per second. At some point, you'll probably need to hire a team to negotiate with cloud providers, or invest in hardware procurement infrastructure.

Anyway, that free tier VM would be able to handle the load, even at such a scale. You might want to add a secondary in a second DC if fault tolerance is important.

There’s an undeniable appeal with toys like these as a means to normalize and explore the world around you freely in miniaturized and simplified form.

So I hope the appeal of toys like these extends beyond just “seeing myself represented” - ideally, kids get to play with a variety of likenesses beyond just “the one that looks like me”.

The fatigue is likely due to negative inotropism. Those newer beta blockers that don't cross the blood brain barrier can also cause the same symptoms in therapeutic doses.
This article makes me genuinely concerned for my own health and future. I was originally placed on clonazepam at 0.5mg/day back when I was a Freshman in High School and have definitely felt reduced levels of cognition whilst on it. I’ve only recently stopped taking it, around 10 years later.
Yeah, agreed. I'm also curious and surprised that it took so long for something like this to arise on hackernews or any social network. I wonder if it was suppressed? I don't even know how I randomly came across it lol.
Unsurprisingly.
I found https://apps.dtic.mil/sti/citations/ADA278191 which has this to say about gold:

>Hypothetical shape charge liner. High density is a benefit but equally low speed of sound indicate s that it may be no better than uranium. An advantage may be found in its ductility, if it leads to greatly improved jet formation relative to its cost.

It seems that sound speed and density are considered more valuable, so tungsten, zirconium, molybdenum.
We've known that efficacy against infection wanes (indeed, this might be expected, as antibodies naturally decline over time - when presented with the same pathogen, memory B cells ramp up antibody production again to prevent severe disease). Nobody was being 'unpersoned' for following this science!

Your county's data is likely co-founded by other factors, assuming it is accurate.

The problem has been those who would try to thwart effective public health response (e.g. by spreading fud about boosters). Largely the motivation is ideological - if the People, represented by the State, could fix Covid with concerted action for the benefit of the whole community, then perhaps they could fix other things, like wealth and racial inequality.
So, much like a Zabbix agent, with both active (push) & passive (pull) capabilities.

We're diving into OTEL, and the registration / discovery challenges don't seem to have any kind of best-practice consensus out there. We're looking at NodeRED (telegraf agent can query from same at startup) but it brings its own challenges.

I haven't read the full paper, but do you know if the push model was revisited mostly for auto-registration / discovery, or performance bottlenecks at the server, or some other concern?

Typically for us, once we've got the hard part - an entity registered - we're happy with pull only. A no-response from a prod end-point is an automatic critical. I guess at their scale there's more nuance around one or more agents being non-responsive.

EDIT: Oh, there's not much in the paper on the subject, as it happens. And yes, it's vanilla discovery woes.

"Push-based data collection improves system robustness while simplifying system architecture. Early versions of Monarch discovered monitored entities and “pulled” monitoring data by querying the monitored entity.

"This required setting up discovery services and proxies, complicating system architecture and negatively impacting overall scalability. Push-based collection, where entities simply send their data to Monarch, eliminates these dependencies."
It's impossible to make a perfect copy of a dollar bill though since it's a physical object. Not even dollar bills are perfect copies of dollar bills. It also doesn't matter where the bill came from: If it's official currency issued by the government then it's worth $1.

A digital copy of a video or a song is similar: It doesn't matter where it came from... it's still the same thing. A counterfeit song or video would be a file of the same exact name and maybe even size as the original but doesn't actually contain the song or video. It's annoying AF when you download a counterfeit file but it's not even remotely the same thing as counterfeit goods or currency.

Can you provide a link the statute or other ratified text that you're basing your "health data" categorization on?

By the way, HIPAA privacy rules regulate the use and disclosure of Protected Health Information (PHI) in healthcare treatment, payment and operations by covered entities.

Per this CDC FAQ [0]:
"""
What information is protected?
All medical records and other individually identifiable health information used or disclosed by a covered entity in any form, whether electronically, on paper, or orally, are covered by the final rule.

For what disclosures and uses must consent be obtained by a provider?
The Privacy Rule states that:
In general, “[a] covered health care provider [with a direct treatment relationship] must obtain the individual’s consent,…prior to using or disclosing protected health information to carry out treatment, payment, or health care operations.” (See section [§] 164.506, 65 Federal Register [F.R.] p. 82810, for complete requirements.)
"""

Non-covered entities, like commercial data brokers, are free to sell PHI-containing data (assuming they aren't contractually prevented from doing so), and unless the data said broker sells is from a covered entity, no plausible interpretation bars the CDC from buying data available to anyone.

> Would you be okay if the CDC purchased data from period-tracking apps to track periods? Or how many bottles of soap I purchase in a year? Or how much booze everyone buys?

Legally? Yes, unambiguously. Morally? Depends on what they're do with their analysis. If it's for disease control and/or harm prevention, that seems to fall squarely within their scope.

No. Omicron death rate is lower.

> The risk of death involving COVID-19 was estimated to be 67% lower (hazard ratio: 0.33, 95% confidence interval: 0.24 to 0.45) following Omicron infection relative to Delta.

https://www.ons.gov.uk/peoplepopulationandcommunity/healthan...

> Despite Omicron seeing the highest reported numbers of COVID-19 cases and hospitalizations during the pandemic, disease severity indicators, including length of stay, ICU admission, and death, were lower than during previous pandemic peaks.

https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e4.htm?s_cid=mm...

Omicron is infecting a heck of a lot more people, so the absolute number of deaths is higher, but the risk of death is much lower at an individual level.
I've been told that the reason carbs are such a problem is that once metabolized into glucose the body has to produce insulin to balance the blood sugar. Eventually this process makes us hungry especially if we eat too many carbs.

One way to reduce the affect of excess carbs is to follow a low glycemic diet similar to what people with diabetes follow. You might want to look into it.

considering how benzos came into existence barely half a century ago, i highly doubt not having benzos as part of one's pharmaceutical cocktail is the fundamental difference maker to one's life or death. so even to those who are now dependent on them, their long-term health will almost certainly be better served by getting to the root cause of their health issues. not saying that's an easy thing to do, but that's still the reality.
The runtime might be an efficient implementation of the language, but the language itself (given GC and still no custom value types AFAIK) implies a distinct bulkiness compared to what I am used to. This is as I said my personal feeling when using the language, and is based on the number of keystrokes I've needed in the past to get from A to B, as well as the runtime overhead (memory overhead for many small objects, add in GC and chances are it's very noticeable time-wise too).

It much depends on the task of course. My biggest project in Java was a SAT solver years ago, and millions of little clauses did not sit well with it at all. I ended up changing the data organization internally. My first attempt, the natural AOS would have been also the best choice performance-wise in C, but in Java it choked the GC. I had to switch it around to SOA which was quite awkward but it reduced the number of objects from millions to a small constant.

Also thinking of the number of lines of code running for JIT, GC, whatever... in the background all the time...

This play of locking all Russia's valuable commodities in, with the only out being in the direction of China, seems risky. It relies on Russia making a series of catastrophic economic mistakes (although, parenthetically, that is an outcome backed by history). The obvious way this plays out is that Russia's economy snaps back really quickly and a Russia-China trade corridor starts firming up because there are no other options. Then they both benefit from it.

It isn't yet so clear that the weak links in finance can be so easily weaponised against a state by foreign powers. Economic warfare always seems to me to be a series of self inflicted wounds. It would be interesting (and terrifying) to see whether these attacks would work against a liberal economy.
