I agree and have had a similar idea for awhile. Have the best lecturers for given subjects create outstanding virtual courses, develop sets of curricula off of those courses, and have TAs (PhDs in your model) provide local instruction and tutoring to augment the standard coursework.

It seems crazy to me that we have thousands of new faculty members and PhDs begrudgingly spending time developing their own way of teaching material (instead of working on research which is what they actually want to do and are good at) when there are people who are clearly the best in the business at teaching their subject matter whose work we should be using instead.
The most disruptive thing about Gmail had @&$@ all to do with user features. It just needed to be "good enough".

The key feature of Gmail was scale, which allowed it to offer much better spam detection, which allowed it to capture more market share, etc.

Facebook mobile is the idea that you have something (Facebook) that was popular somewhere (PCs), that for strategic reasons (TAM / global penetration, location-targeted advertising) pivoted to a completely different medium, and invested non-trivial company resources in making that happen.

The iPod/iTunes were pretty damn big. And specifically, big in demographics that were ideal iPhone customers. Apple in 2007 was very different than Apple in 1997.

Usernames are not always similar to email addresses. In fact, if you are "foobar@example.org", you might find that someone has already claimed the username 'foobar' on Amazon. So I believe your parent commenter's point is that he wishes he could associate both a username & an email address (or at least a comment field) with each entry in his password manager.

Sure. Multiplying a float by an int that leads to AN ERROR because you mixed up your types and you are now losing precision somewhere or other.

Avoiding that sort of an error at compile-time is right there at the heart of the core premise of Rust, so Rust should optimize for it.
Weird question—is there a good way for me to test that the extension is working? Since it should only affect what other people see...
The tax code and federal funding is a very big stick to hold over universities to get them to do what you want. If the federal government can force US states to change their drinking laws through highway funding they can do whatever they please.

Remember, the constitution restrains the government exactly as much as it wants to be restrained.
See my above comment - the choice of metrics in table 3.2 doesn't really make any sense.

Also, they revived some ancient 1998 IBM chip, and report on that, for no clear reason. They call it a 2004 benchmark, but what actually happened is that in 2004 someone made some synthetic variants and put them into a dataset. This is not some widely used benchmark in the field. Given their highly questionable choice of metrics, I would not be surprised if there was some serious cherry-picking on the benchmark as well.
They can change the model later, add caching, improve performance, and use better hardware. Just getting a native search engine off the ground is impressive.

They may be running a flask app reading data direct from s3 feeding through a giant ML model right now - which wouldn't be the application architecture they'd use if they served 100x the traffic.

Sourcetable | Designer / Frontend Engineer | Bay Area (Remote) | Full Time

If you are a designer who is a decent frontend developer and would like to join a 5 person startup, we're looking to bring on a design lead at Sourcetable.

Sourcetable is a spreadsheet that syncs live data from all of your business applications (think: Excel + data warehouse + data connectors + SQL GUI + charts/graphs/dashboarding). We have a top tier engineering team and are looking to bring on a strong UI/UX designer who can also get in the weeds and implement their own designs, polish pixels, pitch in on growth engineering initiatives, etc.

Our team is "Bay Area Remote", which means we're all based in the Bay Area. We meet up in person every week or every other week, and all applicants need to be based in the Bay Area as well.

Spreadsheets are one of the most used business applications on the planet, with design challenges spanning from schema design and user friendliness all the way through to brand differentiation. This is not a normal design role, but should be exceedingly fun for the right person.

We don't have an education or minimum-years requirement for the role, but we do expect that you will have worked at a startup previously.

If interested, send me an email. (My name is Eoin)
I also used to use catch all domains for all kind of registrations and my form was <domain>@mydomain.at (e.g. ycombinator.com@mydomain.at). That most of the time solves the management aspect, except for some special cases where several domains share a unified login (e.g. Google or Stack Exchange).

Anyway, I’ve changed to iCloud’s Hide My Email some months ago, as this is much easier to use and you have easier control on all used emails. You can even add a comment to each address in the moment of creation. Also disabling (blocking) single addresses works like a charm.
You also get stagnation that way.

Meanwhile, Gmail is obsessed with tagging messages I get from nearly every mailing list I'm on, including ones hosted by google groups, as spam. Even messages sent by a gmail user, to a google group.

Outdoor groups? Spam.

Technical mailing lists? Spam.

Social group mailing lists? Spam.

I have filters assigning these messages to labels.

I have been on some of these lists for ten fucking years.

I routinely go into my spam folder and find a dozen messages from these lists tagged as spam, dutifully click "not spam", and rinse/wash/repeat.

Rarely does spam make it into my inbox, but it's so much worse that messages I give a shit about are routinely dumped into my spam box. But not so routinely that I think to check it often enough...

From sources like this [1], it looks like the cohort of high school graduates is usually between 3 and 4 million. So that means the total college-eligible cohort is 12 - 16 million.

Let's say 25% (a fourth) of them end up attending this magical national public college. That's a 3000000 / 10000 = 300:1 ratio of students to teachers. That's a lot of students per PhD to handle, for a $100k salary with greatly reduced career prospects in academia, since they are not doing any research.

By comparison, the student/faculty ratio at a typical "good" college is about 5:1. Even knocking down the projected enrollment one order of magnitude (so 1/40th of the college-age cohort) gets you a 30:1 ratio which is still 6 times worse.

Feel free to point out a flaw here, but I don't think this plan will work. Basically, you'll end up doing a MOOC site, but those...already exist?

The first time I saw this claim was about 15 years ago in libertarian circles, deployed as a talking point against high-speed passenger rail, and justification for lack of investment therein by the U.S.

There's no doubt we have an extensive rail system—most of the country was built by rail—but is it modern? Is it safe? Is it serving its purpose? Seems to me there are many scheduling, personnel, automation, safety, and supply-chain issues constantly popping up around the rail industry, though I'll be the first to admit I'm no expert. I wonder how much of its success relies on work done in the 19th and early 20th century that won't scale (or isn't scaling) with modern needs. I'm curious if there are any industry folks hanging around HN who'd care to comment.

I read from the archive version, and this sounded as nonsense as I expected.

I do not know anyone who acts like any of the references people, a lot of them have behaviours that I would associated with people copying from stories about working in tech and startups rather than actual functional engineers.

The quoted pay ranges also to me indicate that however they’re asking isn’t explicitly separating cash and non-cash comp, which means the quoted ranges may or may not be impressive - generally they just sound kind of average.

A lot of the hype worrying about other people getting so smart or quants, etc does not jibe with my experience either - the combined behaviour seems like it could be implying employees that are say underperforming for their comp, or it could be employees who’s employer is itself on the ropes.

The other 50/50 possibility I could read from this is that there are sufficient worriers on this particular site that you can find enough people to create this story.

Telomeres get a lot of press, but they are only one Hallmark of aging. Other possible related hallmarks I see in this include stem cell exhaustion, epigenetic disregulation, genomic instability and altered cell signaling. Note I have not read the paper and they may have identified other novel mechanisms. If this is a topic you find interesting, I recommend you Google hallmarks of aging. Morgan Levine also has a new book out that gives a nice overview of all the different ways the body messes up as it ages.
Their Like button was pretty ingenious and Instagram is still a market leader. Disregarding the fact that they didn’t create it, they have been good stewards. Also, while VR isn’t big, they did create a hit hardware device with the Oculus 2. While Oculus was acquired Oculus 2 is nowhere close to the experience of the Original wired dev kit, and they iterated from that to the Oculus Go to the Oculus Quest 2.

Also keep in mind Apple has been doing a LOT of prep work for AR. We just don’t notice it but each iPhone comes with a full advanced AR sensor suite, capable of super imposing objects into our field of view. The only missing piece is the physical strapping of the iphone to one’s head, but if you did that the iPhone is capable of delivering Hololens-like promised experiences.
Another explanation that I've heard is that R&D for synthesizers in the 1980s and 1990s got brutally expensive, and a lot of companies just didn't make the transition.
They most certainly are only doing curve fitting.

It's not endowments that makes elite universities elite, it's a combination of social cachet, alumni networks, and brand. Cambridge, Oxford, and Sorbonne have been elite universities for centuries, and it's not mainly from their endowments. It's because if you are [smart|powerful], you want to go to a school with other [smart|powerful] people and you know [smart|powerful] people will be going there. A larger marketing budget isn't going to get people to look at a resume and pick the University of Phoenix over Harvard.
It's a delicate balance. Swing too far one way, and you can make it easy to make very difficult to detect mistakes. Swing the other way, and you now have a system that makes it very hard to just get lost in the process of writing, instead forcing yourself constantly to remember basic low-level details when you should be focusing on the problem.

I generally like C++'s approach. Most things that should work together (like doubles, floats, ints, etc) can work together. If you want to have stronger types, you can make your own classes or use enum classes. If you want, the compiler can warn you about different types, or just let it slide.

> One would expect a given provider should, unless instructed explicitly otherwise, block outside emails from domains it controls mail for.

It's not even something you need to specifically craft much infrastructure for. There are public standards for "don't accept email from this domain unless the sender has a cert encrypted by one of these CAs" (Google runs their own CA, yes?) and "don't accept email from this domain except from these servers" and so on.
- The syntax isn't as good. (this is more like a lot of minor annoyances than one big point, but you can see it discussed in the Swift pitches)

- It's not visible to compiler optimizations so it can't optimize coroutines.

- It's not visible to the OS scheduler, or a green thread scheduler. Any pattern where you start an async task and then later wait on it leads to priority inversions, because until your more important thread is waiting on it, the scheduler doesn't know it's going to, so it can't inherit the priority.

Most of the work I do in systems programming languages is bare-metal code where semantics for representing and manipulating data at the bit-level are required. I need to have very explicit control over the shape of the data in memory. For starters, many of the systems I work with don't even have the ability to do floating-point calculations at all.

> "Compilers (and type systems) are written by and for humans..."

The abstraction that is the type system might be designed for humans, but the underlying physical layers are totally non-abstract, tangible things with their own constraints. If I'm sending data to a DAC over the i2c protocol, the protocol has very real constraints at the electrical level. In order to interact with such protocols in a meaningful way we need low-level semantics to control the shape of data at the level of individual bits.

Consider the following:

uint32_t a = 1234567;
float b = 0.34;
uint8_t c = a * b;
fwrite(&c, 1, 1, stream);

What value gets written to the stream here?

> "first tell me the use case for multiplying a float by an int that does not lead to a float"

Should the Rust compiler forbid all multiplication between the two types that doesn't get stored in a float?
Notably, it's a temporary creation. As those bonds get paid off, along with interest, the fed must either roll that money over to buy more, or simply disappear it off their balance sheet. Which is part of what they are doing now with Quantitative Tightening or QT.

Initial searches look promising, but the proposed costs are vastly too high. In my google history I can easily hit 100 searches per day. If I'm researching something this can hit 1k+ per day.

I'd gladly pay 5/month for search, and 10/month in a stretch. But 300 per month is a non-starter.
I think one of the keys issues is the US News ranking criteria. US News took the easy way out with respect to two significant components of the score [1].

- Endowment per student - bonus points for amassing the largest treasure per fewest students

- Selectivity - bonus points for excluding people before they come in which has no bearing on the effectiveness of the school itself in educating

Also a large percentage weight is given to academic peer ratings of the schools prestige which itself is a feedback loop of when US News used to reward pure selectivity (i.e. lowest acceptance ratio per applicants).

The endowment component of the score should be capped so as not to reward stockpiling.

An additional component of the score should be based on the student body of the school system (higher # of students in the school system is better) should also encourage the development of systems of universities (i.e. multiple campuses. The UC School System would rank much higher - as well as it could lead to the development of Harvard/Yale/Princeton/Cornell/Stanford/etc. School Systems.

I disagree. I went to a "tier 3" school for undergrad and then "elite" schools for post-graduate education. The difference in course and instruction quality, experience level of the professors, student ambition, and caliber of student between the classes of schools was night and day. The "mediocre" undergrads I met during my post-graduate education were as good as the best people I went to school with for undergrad.
