What is Thrift? Is it a service?


Thrift is a software library not a BaaS...


You are in Libertarian La-La Land to call what Uber did "treating users differently based on its interests and its interpretation of the law".

As Volkswagen discovered, in the United States this is called "criminal conspiracy" and "obstruction of justice."


> As Volkswagen discovered

Night and day. Volkswagen was falsifying data provided to the government at an identified testing facility. Uber is fuzzing data and refusing to provide services to certain customers who have not identified themselves as police, though may be*.

A city official cannot demand entry to private property without a warrant. Furthermore, one can eject someone from your place of business--again, provided they don't have a warrant. To get a warrant, investigators need probable cause. There are good reasons we limit the power of those seeking probable cause.


You're confusing the crime with the cover-up. Nobody knows what Uber was trying to hide. The point was simply that such attempts to hide corporate wrongdoing are aggravating factors or can even have legal consequences on their own.

They also presumably did this not just in the US. Other countries have different interpretations of the extend of sovereignty over property, and maybe if an Uber is considered "private". I know, for example, that the police in Germany can demand entry to night clubs during public events without cause or warrant.


> such attempts to hide corporate wrongdoing are aggravating factors

Usually. But I don't believe that is the case here. Uber was public about the fact that they were breaking Portland's taxi rules--they blogged to that extent. Prosecutors had enough evidence to get a subpoena and demand what they wanted. But the cops didn't do that. They chose to collect $5,000 fines from the drivers. That's their prerogative, but that upside comes with a cost.

> Other countries have different interpretations

That might be the case. I am only commenting with reference to American laws and customs.


There's a legal requirement to comply to emissions laws.

Is there a legal requirement to make it easy for cops to use your service? Are they a protected class?

If I didn't want to sell donuts to the cops, I sure wouldn't tell them it's because they are cops. I would just be mysteriously out of donuts every time they come in.


There is a legal requirement to not operate an illegal taxi service.


Physics, specifically their much higher capacitance. The buried lines cost more, but mainly they aren't buried because of physics.

"A typical 345,000V transmission line will be able to deliver no power when the line becomes about 26 miles long."

In New York City specifically most distribution (not transmission) is already underground.

Are we supposed to ignore that our coworkers from these countries can now no longer visit their families or leave the country? Seems a lot more relevant than a point release in some JS framework IMO.


I hate all physicians, except the one who saved my life.


I wonder if greater availability of scheduling information and commuting apps have contributed? Commuting apps make it easier than ever to use public transportation.


Bath County is not the World's largest pumped hydro storage plant. At 24GWh it is smaller than TVA Raccoon Mountain, which is 34GWh. There may be bigger ones, but unfortunately nobody makes rankings of the energy stored in pumped hydro plants.

Re-read the description of Bath County and you will find that they pump from the upper reservoir into the lower reservoir. Therefore, adding the capacity of the two reservoirs and dividing by the flow rate is a bad assumption.


80 MWh is massive for a battery. MW are a measure of power, not energy. You mean MW-h. It's incorrect to say something has a MW capacity when discussing energy storage.


> MW are a measure of power, not energy. You mean MW-h. It's incorrect to say something has a MW capacity when discussing energy storage.

He's quoting TFA,

> With a capacity of 20 MW/80 MWh

It would seem sensible that the system has both metrics: a total capacity of storage, and a total rate at which it can supply that storage to things connected to it.

Further, my understanding is that the parent you're responding to is correct: pumped-storage hydro tends to have much greater generation rates; Wikipedia lists an example of 360MW.


Batteries have inherently high MW per MWh so you can usually ignore the power capacity. But that's not true with everything. Both numbers are important.


>I still remember the  rst time I told my wife that I was in chargeof “Apollo Software.” She exh orted me: “ Please don’t tell any ofour friends!”I suppose real men do “Hardware” just as real men don’t eatquiche.It was an attitude that prevailed a long time in many organiza-tions. Salaries fo r computer programmers did not keep up with thesalaries of engineers.Engineers did engineering.The programming(or coding)was more menial work and should be left to others.

It's funny how much this attitude has changed so much over the years. Now engineering is seen as menial work and the programmers are the real men and rockstars.


It may have changed in the Silicon Valley/tech startup bubble but definitely not in the rest of the world. Engineers still receive far more prestige than IT workers (which is what programmers are largely seen as, technicians) and in most countries, it's as prestigious a career path as being a doctor, lawyer, or professor.

The vast majority of companies that work with physical things, like silicon designers/fabricators, auto makers, manufacturers of capital equipment like machining tools and lab equipment, energy companies, agricultural machine suppliers, hardware conglomerates like GE and Samsung, and on and on, still view (for the most part) software as the red headed stepchild, a necessary evil because their hardware has gotten so complex.


It may just be my own hang-ups, but in the company of unequivocal members of the "professional" class I definitely get the sense that as a software developer I sit somewhere above blue-collar, but barely, and that largely due to salary rather than the work I do.

I'd imagine it's a bit different for the (giving a very generous estimate) 1% of developers who do work that is all of: challenging, difficult, and important, on a regular basis, but that's not me, or the overwhelming majority of people making pretty damn good money writing software.


For the artsy-intelligentsia folks all the people who do technical stuff (no matter if HW,SW, civil engineering) are just "engineers", i.e. people who have never heard about Stendhal or Vermeer. On top of that my ex-mother-in-law, an accomplished theater actress, used to call us non-actors as "civilians", so there's also that.

I for myself don't care one bit how my work is seen by others(I'm a programmer) as long as it's reasonably well paid (meaning I can pay rent, food + some other stuff) and it's not that physically demanding.


FWIW, when we hang out with my wife's colleagues (she's a neurosurgeon), almost everyone assumes that my job is more demanding and interesting. When we hang out with my colleagues, its exactly the opposite. Grass is always greener.


Most of that prestige comes from the mandatory education required to enter the profession. Whereas there is no minimum qualification to become a software developer. (I know some employers have their own minimums but there is nothing for the field as a whole.)


Well, speaking of software… I assume LaTeX-to-HTML is the reason this formatting is so horrendously screwed up? It’s even mirrored in your copy-pasted text (“the  rst time”, “ She exh orted me:” “any ofour friends”, etc). I tried Safari and Chrome and got the same result, and had to read the PDF instead.


At least it made "fi" into a ligature. I don't know what we would do without that.

I apologize for the errors, I'm on iOS and it's difficult to check the output of copy & paste.


>Is this extreme? Putting 140 TDP of CPU heat in a 1U server? Not really. Nick at Stack Overflow told me they just put two 22 core, 145W TDP Xeon 2699v4 CPUs and four 300W TDP GPUs in a single Dell C4130 1U server. I'd sure hate to be in the room when those fans spin up. I'm also a little afraid to find out what happens if you run MPrime plus full GPU load on that box.

What could Stack Overflow be doing that requires such a dense GPU/CPU configuration? I didn't think a commenting site would required that level of parallel processing.



The GPU use is perhaps the most interesting here... Marc Gravell wrote a series of articles about it: http://blog.marcgravell.com/2016/05/how-i-found-cuda-or-rewr...


I know that several years back, they ran all their Stack Overflow from one multi-core Windows server (DB and backend and frontend). And they mocked the traditional Linux setup of multiple frontends talking to multiple DB instances with huge number of small VMs.

Makes sense the server should be really massive.


He doesn't work at StackOverflow anymore.


He was referring to Jeff's conversation with Nick Craver who does work at StackOverflow.
