> Equities is being run over by ETFs, none of these funds have that much alpha, HFT was just some stupid inefficiency firms realized that could do in like 2008, by 2019, HFT is barely profitable. Whenever these firms make money from fast trading, what they are really doing is stealing money from pension funds and peoples 401ks. Clipping and front running trades shaves a little from the price and puts it into the pocket of some "genius" at Two Sigma. You can shout all you want about how intelligent these people are, but the whole thing is crooked. Secondly, watch how fast these places go out of business when the market tanks. Massive bull runs and "prestige" have these guys claiming to be kings of the world, but really, the financial industry is about raising a ton of investment money and figuring out how these fund managers can siphon it off into their own pockets. Which is why ETFs are so popular now.

This is entirely false. I'm not sure where you think you're getting your information from, but it is not accurate. Most highly successful quant firms didn't get that way by raising a ton of assets. They got that way by turning a small amount of seed money into a lot, via returns.

> When Two Sigma starts making too much money, the sec starts knocking on their door. Because its obvious theyre exploiting the market and extracting wealth. So they dial it back, and keep just some. This kind of thing is never talked about in public, but it happens all the time. Constant negotiation between which trades are ethical between computerized traders and the US government. All that 50 Billion in wealth really came from Goldman. Go look on linkedin, all the top people there jump between TS and Goldman.

This is also just absurdly untrue. Nobody is knocking on Renaissance's door when they make too much money, if they did, they wouldn't have been posting the kinds of returns that they do.

You're talking like you're familiar with the industry, but so am I. And basically everything you've said here is just completely wrong. Maybe you worked at a bad firm or something, I don't know. But there are players here who are consistently making large amounts of money from statistical arbitrage, and high frequency trading that has nothing to do with exploiting inside information. And no, the SEC is not knocking on anyone's door for "making too much money".
That's amazing. Put it under your pillow and let us know what the tooth fairy thinks of that little gem.
I'm being downvoted and flagged because many folks reading the comment make their money off the described status quo.
In order to add value to a dev team as a manager, one must have an intimate understanding of the work developers do. There isn't any value in abstracting away from that work when evaluating the contribution of team members.

"Context, action, outcome" is a sufficiently standardized formalism for evaluating performance (assuming outcomes are measured in terms of business value). Accurately reporting context, action, outcome requires understanding both what devs do, why they do it, and how it ultimately produces business value. There's no shortcut. If your management can't meaningfully do that because they are non technical or managing too many people, or whatever, then they are actively harming your team and should be removed with prejudice.

There is no reasonable way to conclude that devs can be effectively measured with garbage stats. Even suggesting it seriously indicates incompetence or laziness.
It's free for me. Same way iOS is free for iPhone and MacOS is free for Macs. I thought that's implied since I already paid for the hardware, but here you have it now, more clearly

> I've seen both cases happen repeatedly. All of those cases would've been avoided had we used a version control system that used branches and merges instead of locks and unlocks.

Well no, the failure modes would be different, but all of those things would still cause problems with branching and merging, mostly because you can't actually merge binary artifacts, only rebase.

And in a world where you can only rebase, locking actually makes sense.
Thanks for the suggestion but I've looked around but I don't see any speaker icon on the LG app. I guess it's different depending on the app and maybe even the country.
So basically the rationale was, because you studied on your own, over what was covered in class, you cheated? Way to incentivize learning...

I have seen many questions on security stack exchange and /r/crypto where the correct answer should have been "use age", but because it didn't exist the correct answer was something bad. openssl CLI is not meant to be used in prod (both because not AEAD and because the man page tells you not to use it). gpg is bad. rolling your own CLI tool using libsodium is not for everyone.
You borrow some money, buy a house, do it up, sell it for more, pay off the debt with some left over for your trouble.

That's using debt as a tool to make more money than you could have made if you didn't have access to credit to buy the house.

Or you borrow some money, build a car-factory, sell some cars, pay off the debt, and then have an income stream you couldn't have had without having access to credit to pay to build the car-factory.

Yes, that's a common view among several schools of anarchism. Reading Makhno's criticism of democracy, and his alternate proposals, which to my eyes seemed to be a railroad towards dictatorship, made me realize that I was not an anarchist but a social-democrat. Which is often a slur in anarchist circles.

A society where democracy can not work because it would be "corrupted by bourgeoisie" has even lower chances of making anarchism work IMHO.

We HAVE to make democracy work.

I stand corrected by an authority on the subject. :)
I've been a professional software developer for twelve years, and while I'm trying to keep an open mind, I have yet to see any useful metrics for what we do. Like, useful AT ALL. I can think of zero numerical metrics that can accurately tell you what's going on with a team. Number of commits, burndown charts, velocity, issues closed/created, whatever, they're all simultaneously easily game-able and also create bad incentives.

And by the way this isn't sour grapes, metrics have almost always made me look good. One job I left, I had so many more commits than the next person that it took them two years after I left to catch up to me. And yet I'm absolutely certain I was not the most useful person on that team. The most useful person was the guy that was writing the extremely sophisticated modelling kernel, and if you only looked at the metrics he probably looked borderline useless, but in actual terms he was by far the most valuable and important person on our team.

What scares programmers is, everyone on our team knew that, and any sort of manager with programming experience probably knows that, but you know that those stats are going to eventually float up to someone who doesn't know that the numbers are bogus. (After all, they wouldn't be tracking these numbers if they knew how bad they are). So decisions do get made from these numbers, even when people promise they wont.

Privacy isn't a singular action and should be a choice, which is a fundamental part of this legislation.

If you're talking about criminal laws then those are designed around harm and the greater good. There's no harm here because it's up to the individual, allows them to gain value from content, and their decision doesn't affect anyone else.

Informed choice is something else entirely, but people go throughout the day making choices out of complete ignorance and that alone isn't a valid reason for preventing their freedom. Considering the relatively trivial risk, this falls well under personal responsibility. I encourage more education around privacy but am absolutely against making the choice for them, because that's how we got into this mess in the first place.
There is argument that it's easier to build car now than in 60ies because car parts manufacturing was decentralized in 90ies. In 60ies vertically integrated car companies dominated market and you could not buy car parts at any price if those companies did not want to sell them to you. Now most parts are produced by third parties (that often used to be part of fully integrated car company like Delphi Technologies) and you can build modern car like legos, outsource pretty much everything and only do final assembly. Still not easy (30k+ parts in every car) but doable.
And, given how many parents let their kids ruin the beginning of life with mountains of student loan, apparently, many parents are also clearly incapable of making a good decision with that information.
I'm not sure about this. I've taken out some loans to finance my education, but overall I would say both experience and financial ROI have been totally worth it.

If I went to any other program, I doubt that it would have been that way (given, the thing I went to school for is weirdly specialized).
I had (still have in a drawer) a 1st gen ipod, but used some gnu audio software (I forget what) to encode (encrypt?) and transfer music I had ripped from CD's I own. I never used itunes.

This is a very nice interface! I wonder how well it would scale for huge PRs (many thousands of line changes), which right now are both irritating to review on Github, and other tools like IntelliJ.

Somewhat related, but I wonder if some of the bottlenecks/constraints in this area are caused by the browser or electron (think GitKraken). I know that there are some new tools out there that differ, such as Sublime Merge which uses the same engine as Sublime Text, but I haven't had a chance to try that out yet.

It may be interesting to benchmark Gitlab, Github, prhero, Sublime Merge and other tools on PRs of various sizes..
> There are plenty of multi-tenancy file systems

Name one. What I mean by multi-tenant is that the namespace, security space, capacity quota and I/O quota are fully isolated and managed at the storage-system API, not via other facilities such as cgroups which aren't even applicable beyond a single-host level. Each tenant gets something that looks like a private service with predictable limits (appropriate for an SLA) regardless of what other tenants are doing, despite being on shared infrastructure. Commercial vendors like NetApp and all the "hyperconverged" crowd have support for this kind of isolation at the cluster level, as do some bespoke storage systems such as the one I work on at Facebook, but in the open-source world? Nada.
I think that people who claim to write many lines of code per hour just don't count small amounts of time lost and don't realize it adds up or feel it should be exempt from counting. It's like the calories in broken cookies, or the ten minutes it takes to get out the door when you only spent a few seconds grabbing a few things.

One thing that I think can give you perspective is if you experience a job where you account for your time like lawyers do, in 6 or 15 minute increments. It's surprisingly hard to get your billable time over 50%, assuming you're honest about it.
That sounds like a radar with extra steps.
You can get a number of small amps these days that will plug into the speakers and sound great.

When the short-term effects are bad, is it really necessary to wait to figure out the long-term effects?
It seems like I have read where "esteemed members of the community" advocate this, at least to enable estimation. Joel-on-software, maybe?
> in early 2016, we were required to cut off streaming to listeners outside the US and Canada

I didn't fully understand who it was that required 8tracks to stop streaming abroad, but I wholeheartedly hate them so much. It was my preferred music service, I loved discovering all sorts of playlists and new music, while I've always disliked the Spotify client.

To see it dissappear, probably due to greed from royalty owners somewhere, was a loss. Now it's all just random Youtube mixes, but it is not the same.

I also used some other site that tuned music according to a chosen "mood"... but cannot recall the name right now. Stereomood, maybe?

Democracies can't work, as they're managed by politicians with low time preferences, which means that in order to get elected they'll promise and pass laws and regulations that make the government always spend more than what they make through taxes, disregarding long-term effects. That process generates debt.

Democracies inevitably end up achieving state bankruptcy through excessive debt. Regardless, that debt has to be paid by the population, so in that perspective democracy is a poverty generation engine.

This is, of course, a silly article.

Firstly, it seems to predate or not include the Apple Watch models (series 4 and 5) that have ECGs. The article mentions that they got a notification about irregular heartbeat and then got mailed ECG test kits, with a 20% return rate.

The new watches just perform an ECG directly, which I imagine has a much higher conversion rate.

It's nice to see a recap of this afib study, but the angle of the article seems pretty unhelpful.

The title claims the watch "Can’t Replace Your Doctor" which is as far as I know not something anyone rational claims or believes. So it's not surprising to learn that it cannot replace your doctor.

Also the subhead is completely false: "Apple has been advertising its watch’s ability to detect atrial fibrillation. The reality doesn’t quite live up to the promise". It, as the article discusses at length, in fact _does_ detect atrial fibrillation. In 153 people in the study! Sounds great! Advertising confirmed correct!

I'm not sure what I'm intended to take away from the article. The Apple Watch detects afib as advertised? And that could possibly be Actually Bad based on some handwavey mention of "misdiagnosis" (the watch does not diagnose you, your doctor does).

Am I missing something interesting here?

Read the full article of Monty's criticisms of 192 kHz, it answers this question. https://people.xiph.org/~xiphmont/demo/neil-young.html

His point is that once oversampling and filtering is done in hardware, the final output only needs to be encoded in a low sampling rate for its benefits, and all high-quality DAC and ADC already oversample the signal under the hood. Using 192 kHz for its output or music distribution is unnecessary, and only introduces drawbacks like additional IMD and wasted space.

The NIH budget is about $40B. Between NCI, ACS, etc, on the order of $10B+ on cancer research.

I don’t know how much YC invests per year, but back of envelope seems like $75-200m.

Or not even 1% of the NIH budget.

Having worked with both YC and NIH processes, I would say the former is 100x more capital efficient, and if NIH were to give YC 1% of its budget to distribute, you would see blockbuster returns. As it is NIH wastes billions a year on overhead of its application processes alone.

gasp include senior devs in a conversation about development? Blasphemy. At so many places it's like there's some unwritten law that you can't include developers in any sort of business conversation, you need to hire a project manager as a go-between in order to badly translate things between business and development so neither side actually knows what's going on.

Maybe this is a first step.

What I never understand about articles like this written from the perspective of Americans is that they don't seem to consider that there are other countries than the US? Why limit yourself to the US when education is much cheaper in other countries. And, it's not like a Art degree from a European country is going to be worse than from a US school, it'll probably open more doors not to mention that learning the language will be useful...

People all over the world think internationally when selecting universities yet people in the US somehow limit themselves only to their own country.
Your school may be an exception. There are exceptions for most people, but the acceptance rates are low. For example, a well adjusted middle class child would be a foolish in most circumstances not to take out debt to attend Harvard, Yale, Princeton or Stanford (and a select few other universities where you can maximize the chances of vastly increasing the status of your social network with four years of camaraderie). However, after you dip below a certain level of status, the benefits are much less clear.

A middle class child may never have the opportunity to get exposure to one or two notches up save for education. But this only exists in a select few places.

> [FPTP voting causes] those parties to coalesce into two dominant, equally balance parties

California has FPTP voting and is completely dominated by Democrats who have a super majority in the legislature and the Governorship, and can pass any legislation they want without a single Republican vote or amendment. That's been the case (with a brief stint by Arnold) for multiple decades.

Tell me again how FPTP voting necessarily results in two equally balanced parties? I'm not seeing it.

Separate from this issue here, Sonos should be off your list. The UX becomes progressively worse and opaque, your time will be wasted owing to mandatory software updates, needless churn, etc.

Focus on what you know. Make sure your team includes at the very least (in no particular order):

- Someone who is part of the target audience. They should be able to provide your team with a good idea of the features you absolutely need to get started, and might be a good source of ideas for differentiating features.

- Someone great at manual quality assurance - user testing, poking the system through the laughably complex and diverse devices we all use, and ideally translating manual test scripts to automated ones, where possible. Lots of software has massive amounts of features hidden behind a broken UI.

- Someone great at UX, in particular related to the type of UI you are building. Web UX is not the same as desktop or API UX.

- Someone great at automated quality assurance - TDD, CI/CD, linting, fuzzing, code & user metrics, telemetry, performance and stress testing. They keep your progress from stalling over time.

- Someone trusted by the entire team to plan, direct and arbitrate. They avoid double work, keep the team going in the same direction, and keep interactions human rather than textual (which has far too low bandwidth to avoid conflict in the long term).

For most features you'll want all of these involved in the planning at the same time (and place, if at all possible), to get the most out of everyone's time. They'll all be able to see how the work fits together and will provide unforeseen insights and questions crucial to building an excellent product.
It's still super-easy to game. Just prioritize all the low-hanging fruit. Got some tickets for increasing the font size or replacing the copy in the privacy policy?
