No, not at all. GPA tells the difference between "mastered the material" and "did well enough not to get expelled" which can be a useful signal for an employer, but universities and professors don't view it as their responsibility to sort students for industry's needs.

For starters, the quality of students is not uniform across universities. Middle of the pack at Harvard is a very different thing from middle of the pack at a party school. To get a useful ordering, you'd need to give every CS graduate the same standardized test, like the bar exam.

It's more than just trade protection, it's a matter of national security. US airlines are legally subject to having their aircraft commandeered to transport military personnel in wartime. It wouldn't be feasible to enforce that requirement on foreign airlines.
I had been experiencing a similar bug that we reported to Red Hat after being stumped. It started occurring out of the middle of nowhere but it would happen only in .01% of our jobs we launched into a batch farm. We launch about 15k batch jobs a day, and it was enough to be a problem.

Before a job was launched, a daemon pre-staged some job contents (logfiles, env, etc..) and started writing out to a job summary file. Then the job would start, continue writing to one of the files, which would become corrupted.

It ended up being this bug:

Facebook currently make $60 per user in the US, a little less for the EU, and basically nothing per user in the rest of the world.

It seems doubtful that to many people would pay $60 per year for Facebook, at certainly not $600 if they where to make 10x (minus the overhead of running ad sales)

That's also the problem of our current political systems which favor party lines instead of individual thinking. It's very inefficient to drive reforms.
Ask HN: Good General Design books?
I have come to realize that design is not partial to any particular product or profession.

It is integral to every good thing on this here earth.

Thinking about the website user, the person who's going to live in the house, the person who's going to drive the car, and the person who's going to use the tool, etc. 7

They are really the same thing when you get down to brass tacks.

So I ask you HN, is there a general design book out there that teaches the aspects of good design in general?

Or is it so straightforward that the only thing required is common sense and a lot of it?

Cheers.
Could you give us an example of a specific FAA or NTSB regulation which has a suboptimal benefit:burden ratio?
Credit specialist
My name is Robert and I was so ready to purchase a home but my credit was in a terrible condition and wouldn’t let me qualify for the purchase. My credit score was less than 550, and I had charge offs and a lot student loans. I’m a veteran, so I wanted to use my VA COE, however I was in dire need of credit repair. I went on Trulia community page in search of a credit specialist. There was this particular specialist that was widely spoken of and I read quite a good number of nice review about him so I contacted him (CREDITSPECIALIST4@GMAIL.COM, +1 912 388 3132). After discussing the process, we got started with the process and within some couple of days, he buzzed and asked me to pull my report and that the job was done and looks good now. Pulled my report ASAP and found my score has been raised to 798 and the student loans, charge-offs, all deleted. I bought the house without stress. Contact him with the above information for your credit issues.
> Imagine if there were no governments.

Then someone would assume that power. Anarchy is not stable.

In the absence of any other government, any “company” is a government unto itself. And any that raises an army, by whatever means, pretty quickly makes that even more clear.
There are loads of products that I would consider classical monopolies in tech. E.g. Youtube/Facebook/Android/Whatsapp.

Sure you could use one of the alternatives, but then you won't get the content/people/apps/audience/... that are on those large platforms, which makes them basically useless.
I didn't mean to cause offense. If you could please show me where I went wrong here, then I'd appreciate it.

Technically "next year" is 4-56 weeks from today Nov 29.
The Diablo immortal fiasco is certainly a dramatic misstep in terms of who they're presenting to, I'd agree. It was also quite painful to watch. However, I was pretty excited to see the announcement of a future remaster of Warcraft 3 from the same event.

You certainly have a point, but I think it's also really easy to develop a characterization of a company based on relatively shallow information. I had a conversation with a friend recently who's not quite in the same situation, but is worth recounting anyway. We live in Vancouver, BC, home of one of EA's campuses. He went to school for game design, then proceeded to not do anything relevant for about 6 years. He has no professional game design experience to speak of, yet has a tendency to speak as though he does. It seemed to be a surprise when I broke this down for him. When I asked "We know multiple people at EA right now, who, despite EA's reputation, speak highly of the company. You have a certification of some sort, why haven't you applied?". He proceeded to describe what he thought of EA, based on some of the decisions they've made, some of the games he's disliked, and the internet's opinion of them. The conversation went well, but I had to feed him some harsh realities, I hope he does well.

My point is not so much that it's not valuable information, but it's not a lot of information to bet potentially very valuable experience on. If you can say "I worked for Blizzard and it really wasn't for me. But I gave it a shot." then that might give you a lot more information in terms of what you do want to do.

This relates to me a little as well. I'm at a crossroads as a developer. Having been a web developer for a few years, with no degree at the moment, I'm trying to figure out where I want to be. A few years ago the prospect of working for a large online auction corp. I had a very strong suspicion that I would not do well—culturally and otherwise—at this company, but it was double the money and I was at that time not doing anything constructive. So I set my ego aside for a while and proceeded to take the job and subsequently confirm my suspicion. It wasn't all bad, but near the end it got pretty bad. It was a mistake I don't regret. It cost me a lot emotionally, but now I know which kind of companies I won't work for. I have a lot more information to go on, and sometimes those risks are worth taking.
Sounds similar to Consul, which has a similar architecture.
I lived there for 4 years and you shouldn't trust the random pictures you see on the internet. The place is a shithole.
But planes are ultimately safe, to the extent that the major US airlines often go a whole year with zero passenger deaths. And this safety doesn't even cost more; it's actually cheaper than the alternative when you net out all the costs.
Thinkpads were actually manufactured by Lenovo right from the start, they were only badged by IBM.

But even then, why should anyone at IBM care what happened to the brand after they sold it? I know some creators love their product lines and such and care about posterity, but, IBM!
No, Facebook sells attention of relevant users, which is a product which Facebook uses user data as a tool to craft. That's not the same as selling user data, in the same way that, say, investment houses aren't selling Microsoft Excel.
There are no legitimate Windows licenses that only cost 10€. They may activate but successful activation does not imply that you are not breaching Microsofts license agreement and they may decide to deactivate those licenses at any time
Interesting, I actually implemented a simple immutable ledger on top of mysql this year to track balance mutations of our InToken coin. The coin exists on Stellar as well but we track federated stellar accounts in our database for most of our users. This means that we represent them with a single stellar account. We allow users that clear our aml procedure to send/receive tokens to stellar.

Having our own ledger means we can cheaply do internal transfers, micro rewards, and other incentives. Doing the bookkeeping correctly and in a tamper proof way is of course important for us, which is why we built our own ledger database to ensure we don't end up with corrupted data (either through bugs or malicious activity).

I use content hashes as the id that include the id of the previous ledger entry and the key data stored in each row. The core design is pretty easy (it's basically a linked list) but the devil is in the details with this stuff since you indeed need to worry about auditing and making sure you don't end up losing transactions.

Additional headaches include dealing with concurrent transactions and the fact that mysql does not do serializable transactions (at least not in sane way). Each row should only have 1 successor meaning that every new row involves looking up the previous row, and using it's id as a parent id. So we have a select and an insert happening in a transaction. We have a simple db constraint enforcing the parent is referred only once. We retry transactions when this constraint gets violated. This does actually happen when two concurrent transactions decide to use the same parent id. If transactions were serializable, this would not happen and the second transaction would end up using the id of the first.

Another of the gotchas is that data migrations are kind of hard/impossible in an immutable data store. The only way to do it would be to effectively recreate a new database with new content hashes. So there are some things that I'd like to change that I can't actually change because it would break the content hashes. But by and large, this design is working quite well for us so far.

So, in short, it's not rocket science but hard enough that having a well supported product that does this is worth having. We're actually considering open sourcing it at some point since it seems there are quite many projects out there that use a ledger primarily to have some tamper resistant immutable and auditable log of transactions.
Thanks! I haven't posted it yet, as I want to test how reliable is the approach. I know it does not work with non-mechanical keyboards at all (most likely because the key sounds are quiet) and I have tested it only with my mechanical keyboard.
From what I gathered from the mobile version (which may be paired down), the difference was not that significant, particularly in the analysis of evaluations and RMP submissions. Would have liked to find more on class composition, and would be curious how reproducible the relatively minor absolute differences would be, but "ridiculously sexist" seems a bit hyperbolic. Do you have a specific take on those studies that inform your opinion? I could be very well working with not enough information here.

We load millions of rows per second and use a handful (or more?) of materialized views to build appropriate summaries. Various clients make queries to the "raw data" and the views and it all works fine, basically.
I think about this often. I imagine self-driving cars built on 30 year old tech in which the road drives the car via curbside sensors (much easier problem to solve). I daydream about service reps walking through bumper-to-bumper traffic handing out coupons and apologizing for the unexpected delays.

Pay to drive the premium roads when you’re in a rush, or take the discount lanes with advertising printed along the roadway.

We could have quiet, porous asphalt with better water absorbtion. So many fantasies, I digress.

In your example, the cheap retailers are subsidizing the price of the quality products with the ill-gotten gains from selling the crap products to less-informed customers. Those customers unwittingly waste their money, so that others can buy slightly cheaper products.

The completely free market does not work in practice, because people are not rational, perfectly informed actors. They make non-optimal choices and tend to not learn from them, and they're easily swayed by advertising.

Sensible warranty and returns laws exist because businesses have gotten away with providing lousy quality products for far too long. And consider the longer term effect of sensible consumer protection laws. If a product gets returned too frequently due to quality issues, the seller will stop carrying that item, improving the overall quality of his selection of goods on offer. The manufacturer will wise up and either improve quality or go out of business.

In the EU, any online purchase can be returned no questions asked (in like new condition and original packaging) for 14 days after receiving the item, though you do have to pay the return shipping costs. This has markedly improved the quality of items on offer, because the sellers don't want to carry items that get returned too often, ie. crap products. Prices haven't gone up.

E2-E4 was a breakthrough. It's descendent of the Berlin school of electronic music of the 70's. It's difficult to place that track in a genre, for me it's just electronic music. The long guitar solos of the B face is not something you will find in Acid/Dance music.

Iterestingly in the modern approach to set theory there still are both ordinal and cardinal numbers, but you can't say that the cardinal n is the set of all sets with cardinality n, because this is a proper class. Instead we choose a particular representative for this class, which also happens to be well ordered (this is in ZFC, you can still pick representatives for equipotence classes in ZF via Scott's trick but they are not necessarily well ordered or well orderable).

Carlsen didn't play the games, he played the tournament, and won.
Also, there is no real market for airline tickets, because you can't, as a consumer, decide to resell them. So their prices are often set in very bizarre ways (leading to prices jumping around minute to minute by crazy algorithms.) I think a big part of this situation is for security purposes.
Specifically speaking the optionality (inexplicitness) of parens for function calls causes some parsibg difficulty. The compiler automatically assuming that a bare atom is a function call with () versus a variable, for example.

From the analysis Carlsen used his advantage well: to secure continued advantage.

> (2) people might individually be better off but society as a whole could be net worse off due to externalities (costs not borne by the people making the choices and so not considered by them).

I'd add (2a), due to zero-sum games. This is frequent in competitive situations; I buy something (e.g. advertising) to get ahead, and now you have to buy it too just to keep competing. Then you buy more of it, and I have to buy as well. And since effects of each purchase get cancelled out by other party's purchase, everyone is back where they started. In a perfectly abstract way, there's no externality here - though in practice, anything you buy involves some externalities, so you have them here too, in addition to wasting mine and yours and other competitor's money.

It's a trench warfare.

> It is true that these problems are unavoidable in a free market. However, outside intervention does not, in general, solve them. In fact it almost always makes it worse, because whoever is making the outside intervention has even less at stake in the choices about what to "vote with money" for than the people making those choices.

Can't agree with that. Free market by itself is neither willing, nor in a position to, account for externalities. Also, you could group (2), (2a), and couple other similar things under the general label of "coordination problems", i.e. things that look like iterated prisoner's dilemma if you squint. For that, the best solution involves an outside party unilaterally establishing accepted rules of behaviour, forcing cooperation instead of defection.

> I think the best we can do is to try to give people the best tools we can for making their own choices, not trying to dictate those choices by outside intervention.

Again, this is how we get into coordination problems. This solves (1), but really causes (2).

i recently graduated and started work.

academic achievements, relating to actuall work, is a drop of piss in an ocean. my experience at a university actually made me lose respect for academics.

edit: who ever is downvoting is romanticizing the achievements of scientists of yore. or thinks that MIT is the norm.

no, for the most part its publish or die, ive heard professors refer to students as "harvest" and laugh, while copying slides off of google. ive seen professors lie their way into grants.

all that contrasted with how the industry actually works and its needs, and what it actually require the universities to produce.

yeah, ive become a achievement oriented cynic. titles truly only make me think less of a person if thats all they have to impress with.

CREDIT SPECIALIST
My name is Penny and I am from the state of Mississippi. I filed for bankruptcy in 2016 and have one lien on my property as well as student loans and several late payments. I needed capital to start a business but my credit score is in the high 500s and they wouldn’t get a loan approved for me. I found an information about a trusted credit specialist (TROJANVIRUS212@GMAIL.COM, +1 912 388 3132) while doing a search for credit score increase online with several references to his work and I buzzed him ASAP. He gave me a quick response and explained the whole process to me. After I gave him the info about my credit profile as he requested, he told me the job will take 5 to 7 business days and that was awesome. He pulled through, raised my score to 792 and deleted the Bankruptcy. All debt were marked as paid and late payments appeared as on time payment. I got the loan and I have started the business. Go to him now with the above information and be as happy as I am.
We sent very carefully hand-crafted invitations to all our guests in the mail. We did a wedding website to get the RSVP's, as we live in a different country to many of our guests so postal RSVP's would have been difficult (we sometimes have issues receiving mail here). The website was also a great information point on how to get to our venue.

So basically a bit of old and a bit of new. It worked well :)
