skysight-inc/HackerNews huggingface dataset:
You're reading a bit too much into the "raw data" part. An average event that is saved to disk is about 1MB in size but that is with compression. The uncompressed ADC counts obviously would add up to a lot more than that given the number of readouts in the tracker, which is only one of about a dozen sub-detector systems. So saving every event to disk, with compression, would amount to about 40TB/s. Since there are a number of caveats I was only using an order of magnitude to illustrate the scale of the datasets being handled at the LHC.

I'm sorry if I sound dismissive here, I don't mean to be it's just impossible to go into all the detail of these machines in an HN comment. They are unbelievably complex (and fascinating!). I encourage you to check out the CMS design doc that will cover most of it in extreme detail (it's almost 400 pages) [0]. There is also a much more general overview of the various detector subsystems that is considerably more concise [1].

To answer one of your questions though: the tracker is used to measure the track of charged particles through the magnetic field and determine their momentum. This isn't enough to tell us their energy though b/c we don't know how massive each particle is. This is why the tracker is surrounded by an electromagnetic calorimeter (which "catches" electrons and photons) that is surrounded by a hadronic calorimeter (which "catches" hadronic patricles like neutrons and protons). The information from these systems is combined to ID each particle and determine how much energy it had, whether or not it decayed, etc. This is generally how we study the physics involved in the collisions but in reality it is 100x more complicated than this and there are number of other detector subsystems involved.

Congrats Qi!
On the work itself, if it isn't being micromanaged, there's an opportunity to adapt it to what interests you. What do you want to get better at? It doesn't matter if it's generalization or specialization, the company likely wants a low maintenance solution regardless of how you get there. In the long run, an important part of work is making it your own, getting what you can out of it so you don't feel stifled.
Which defeats the purpose of hiring good folks who have the ability to build amazing things. Why do we have a hiring process in the first place if the current evaluation techniques aren't meant to solve the actual need? Companies hire engineers just to have more employees?
Re-read what I wrote. Imagine a machine with 8 cores and 16 hyperthreads. Now imagine you need to optimally use the execution ports in each core. To do that you would need to have 16 VM threads all feeding the ports simultaneously, 2 per core. If all your workloads on that machine are from different customers, you can’t do more than 8. If you timeslice more than 8, then the question is, what is it that you’re selling as a vCPU? If it’s a timesliced core, then it’s not what they say they’re selling (a hyperthread).
I think this is especially true for SW engineering. You can't just constantly discuss things but you also need uninterrupted time to try out things and see how they work out. Then you can discuss the results again.
Are you refering to Trump or Castro here?

New things get added over time. Cortana suddenly starts "reminding" you of all the neat things she can do. Windows tells you your computer is at risk because you aren't sending all your data to One Drive.

Sure you can disable some of them but its like whack-a-mole and your an update away from a new nuisance. The speculative app installing (which does get actually installed) requires a registry change to disable - not exactly user friendly.

I paid extra for a "professional" operating system. Why am I getting candy crush?
When I used to live in a "normal" part of the country, telling people I'm a Software Engineer would usually lead to one of two things:
1. They'd pivot to asking me where I worked (which I didn't feel comfortable sharing with a random stranger, since I worked for a small enough place that it felt a little too specific)
2. They'd lump me in with the annoying IT guy who fixed their stupid Windows issues at work.

Now that I do live in the SV area, I guess I carry some of this baggage with me. I work for the sort of place that would get me local "street cred," but still feel uncomfortable sharing it. Then again, I'm also raising a family and never go to parties anymore, so the opportunity doesn't actually manifest.
These sort of rates were real in the past, but regulatory changes have decreased them dramatically. In general, much less than $0.01/mi at wholesale rates.
Drawing from your last comment: Why do you think you/we do this? What is the emotional need?
For someone who is preparing for interviews, this is really good advice. Thank you.
This is almost a cliche of people who don't know shit shout cuba.

They've had an Internet for years with no wifi. They have mechanics that can reliably work on cars from a half century ago.

Cuba is a wealth of intelligent engineering minds, plagued by reprehensible Communist rule. Money has never stopped the cuban spirit.

It's a disgrace to compare the Cuban spirit to Saudi Arabia.

Configuration state is the bane of server management. Ideally you want to maintain state in a system specifically designed for it - i.e. a database, or version control software.

Well you wouldn't want to promote the most gullible would you?

I think cynical might be a better description than pragmatist. A pragmatic person might see the reward in working hard but a cynical person will see through that. It's a shame cynicism has come to be seen as a negative trait (probably by people who like to manipulate you), a healthy dose of skepticism, cynicism and pessimism has served me well so far in life.
That was exactly my point. Why single out Cuba for sanctions when the US has normal relations with countries that have sketchier track records.

Nginx won because it was faster, simpler and more easily extended, not because it was "lightweight" per se.

In comparison, dropbear doesn't really do anything that ssh doesn't, and lags in a bunch of esoteric features that "most" people don't use but that inevitably some people do. Who wants to use a distro where one's preferred ssh-agent feature or X11 forwarding inexplicably doesn't work?

Dropbear is small and builds cleanly everywhere, so it's what you pick if you're size constrained or just need "an ssh" for your embedded environment and don't want to bother integrating something larger. No one specifically wants it at the command line on their "Linux" system.
You might not even need most of that country data in your database though, it could be in your application in many cases (the fastest join your database can do is the one that you do in frontend code instead)

> I found myself really unsettled by this. Light a fire, and turn up the air conditioning?

You should be, I've never seen anyone in Texas do this. Many fireplaces throughout the state (that average both colder and hotter than Houston which fluctuates temp much less than other places) are used as they are in other states, just less frequently and the fireplaces are not designed to heat as well. And people don't run A/C in the winter in places like Houston unless there was a very rare situation.
I do the "open windows, A/C on" thing sometimes in my car. Too warm to really be comfortable with just the window down, but I really like the fresh air a lot more than the super dry cold air coming from the vents. I wonder if that's the same motivation for people who open windows in an air conditioned house.
Scooters, bikes, are "new" in the sense of traffic norms, unlike the tractor.

Sole-vendor contracts with major metro areas, piped into all public spaces, stores, restaurants, bars, coffeeshops. Incorporated in other entertainment (films, video games).

That's control over channel.
I was just thinking about this post again today and came back.

It reminded me of a quote from Steve Jobs about a calligraphy class...

“If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts.”

You never know when a skill will come in handy again until you actually need it. I remember learning how to make logos using Inkscape several years ago on a whim, and now I have used those same vector graphic skills multiple times in CAD work or making graphics for a help guide for a product.
The GP was probably just making up numbers or basing it on costs for a single person.
For bitcoin to help:

1. Bitcoin would need to be more stable. No reason to think it couldn't drop more than Turkey's currency.

2. You'd have to predict that the lira was going to drop a fair amount of time before it did... (meanwhile take the risk of #1... and ho man has it been wild).

Neither of those are things and even if Bitcoin was say stable and predictable #2 means you'd have to have "the people" speculating about currency.... that's not something most people are good at.
Actually it told me that simple stuff is unnecessarily complex, so that’s not nothing.

This is not a problem in India as a lot of treatment s in govt run hospitals is free for low income people. But then, the problem is that such hospitals are hugely overused and the quality of care suffers. By enabling the poor to use private options the demand can be better distributed between private and public.
what? centralization doesn't need to come first, it was first! First banks had private ledgers with no use of cryptography, then banks started using protocols and cryptography to prove events among each other and from users, then the current crop of primitive and inefficient blockchains proved we could scale the number of independent verifiers to much larger numbers intead of just a couple of banks (each client of users who can afford to download and verify the complete blockchain), and the next steps will be devising a system that is more enerrgy efficient and scales the number of economic participants (not just the number of verifiers) see Algorand for example.

this is written by somebody who doesn't seem aware banks were using ledgers (~ block chain, or timestamped transactions) and cryptography way before bitcoin.

Bitcoin merely substantially improved a subset of certain undeniably important aspects, while neglecting some of the others...

Also, a good tutorial for beginners... is the Vue guide itself, it's concise and authoritative:

https://vuejs.org/v2/guide

Devote half a day (more or less, depending on how fast you read/take in information that you might use later), read through the "essentials" section and "components in depth" at the very least, and then get started building stuff and use the guide as a reference (and also the actual API reference).
> I already know exactly what I want and I know how to make it testable. An even bigger issue I have is the huge reliance on mocking which leads to completely brittle tests and code. ... use unit testing for non-trival logic.

Couldn't have said it better myself. If you're unsure about the best form of your API, then TDD can be hindering. Tests are important but TDD can be an anti-pattern.

TripleByte gets plugged a lot on HN, but I think a lot of people still don't realize what a great time investment it is. I woke up early and did their 3-hour interview before going to work one day. Within a week I'd been offered 30+ on-site interviews at well-funded Bay Area startups, as well as a couple of bigger companies (Palantir, Stripe). Their interview was engaging and challenging and produced lots of useful feedback.

You also get lots of chances to talk to the founders of companies (or sometimes employees for the bigger ones) and evaluate whether an on-site is worth your time.

Especially valuable if you lack a big name on your resume and can't open doors that way.

Facebook is a business, Youtube is a business, Twitter is a business. If they determine that certain legal content is going to cost them business, they are not going to allow it. That's just the way it is. Which is why all of those companies disallow harassing content, and why two of those three has kicked Alex Jones off of their networks. These are business decisions.
HappiLabs is right that pricing is all sorts of messed up across the sciences. That anecdote about labs in the same building having different pricing is all an all too common story I hear from plenty of folks in the lab.

I see time getting wasted every week, and not just from folks managing the lab. Often, as soon as the weekly planning meeting ends even scientists will get out their laptops and start bouncing between VWR, Fisher, Sigma, etc's. websites to figure out where the best prices are, how long it'll take to get what they want, and shipping costs. The fun part is when the stuff arrives and they realize their inventory count was off and they're actually out of something they thought they had in stock...and then it's back to the same old websites.

It's good to see YC investing more towards solving this problem. I know Quartzy (YC S11 - https://www.quartzy.com/) has been working on this problem too, a bunch of labs I work with are using them for this same issue. They have a ton of partnerships with suppliers which has allowed them to consolidate all those vendors into one place. This has solved a lot of that price hunting, but I think there's plenty of room to expand with more automated inventory management since that's really at the heart of a ton of supply issues.

Honestly, thinking about it, there's a lot of stuff in the lab that automation would help with beyond the experimentation part which gets the majority of attention at the moment.

Nobody is required to demonstrate need to King-Aaron. Your opinions on the policy are not relevant to the practical concerns regarding its implementation.

For the record, I agree with you, but this isn't really an appropriate place to soapbox about it.
(disclaimer: I've worked at two mega corps and a startup and generally favor my experience at the second mega corp so far)

I think your example points out a factor, but not the only factor and probably not the biggest factor. You can also say that startups don't live long enough for their code to grow organically from their original, pristine design and develop deep seated code "cancer" like mega corp code does. Also, even without turnovers, some features just go through enough code modified by enough engineers that Murphy's law happens and things break in creative ways that E2E tests catches or could have caught. And finally, just because I remember my code today doesn't mean I'll remember it in a year or two... I don't assume that my coworkers have perfect memory either.
I can try to highlight a difference.

At least in terms of depression feeling numb and losing interest can feel involuntary; a feeling like nothing can penetrate this deep fog that you've nestle into. You sort of know you don't want to feel this way but the tricky bit is teasing away if it's "health" or "circumstance". But I think for the author this would fall under "actually unhealthy".

Contrast this with something like narcissism, psychopathy, or school shooters where the author might say: You just think they're ill because you think they're assholes, inconsiderate, or evil. They're not ill, they just don't play by your rules.

Disclaimer: Unfamiliar with the book. The preceding is speculation of the point of view as explained by the parent, but a view that I sorta resonate with.

With every school shooting or public massacre there are these long diatribes about it being a public mental health issue (or a gun issue?). Why can't they just be evil assholes who didn't have much to lose? or chose to act out in a vague revenge against society? I'm not saying I disagree but I suppose I'm skeptical it being painted as so cut and dry.

Cuba is treated different because Cuba is close to HOME. The only time US was close to a nuclear war and main-land invasion was when Cuba gave their enemy a foot hold.

I would point out the very fact someone was willing to risk jail time to steal that CD collection means it's not worthless.
I see it as security is about control, and privacy is about removal. Privacy and security aren't mutually exclusive, but they aren't exactly symbiotic either.

It's fair to say an individual would want both security and privacy (for example, as with your home). Like many things, it's about finding the right balance. I'm sure if you look to the extremes of security and privacy you could find a bunch of crazy examples.

The wildcard is the who. That is what throws off the scales, as the security/privacy relationship moves from a micro to a macro level, and suddenly a person's real autonomy comes into question.
Ah, this is the same Qi Lu who was basically responsible for the creation of Bing, then got Office and AI in a reorg, and then somehow got pushed out by Satya and went on to be CTO of Baidu for awhile.

The YCR connection makes sense, since he has a lot of experience in AI where much of YCR is now at, but it will be interesting to see how he will interact with Bret Victor's group. Are they going to start a YC-like incubator in China? It will be interesting to see how this compares to Kai Fu's Innovation Works.
