Although I agree it's annoying and negative marketing, it's also being completely overblown here. This stuff is just a minor marketing gimmick.

Paying with credit card is in itself rare in most of the world outside the US, where debit cards and cash are way more common. My guess is, 95% of all locals and non-US visitors automatically pay with cash and don't even notice the Visa-only signs.

Not having the local currency on you and waving your credit card in situations where it's considered inconvenient and inappropriate is a very typically American tourist thing to do.

And I really can't think of anything within the Olympic venue that would be considered appropriate to pay for with credit card.

This really depends on the kind of code generation being used. There's "dumb" code generation, and there's a DSL.

In the "dumb" case, the input is usually some tabular data, and the code generator simply translates it to valid C syntax. It makes sense to say "it was written in C" in this case, although it's a bit moot since this is just data.

In the DSL case, the logic is actually coded in a different language, and the code generator translates it to C. Here it would be more difficult to argue that "it was written in C", because C just serves as a compiler intermediate language.

Naturally there are levels in between the above two, but the point is that it's difficult to judge without examining the actual module that was auto-generated.
that's useful, thanks!

There will always be someone lamenting that language X (insert Lisp, Smalltalk, Haskell or anything else here) is not being used instead of the horribly terribly utterly broken C, C++ or Java (yes, I'm being sarcastic). But in the end, pragmatic concerns win. Nobody works in vacuum, even if they really want to.

I'm a big fan of functional and otherwise dynamic language, but if I had to write my own Mars-landing controller, I would use C. No doubt there.
Since I've been downvoted without a response, let me elaborate on my concerns. I haven't seen the threat of application specific passwords (ASP) addressed properly. If an ASP is sniffed or somehow extracted from a device it seems like it's practically equivalent to a single-factor authentication password. I couldn't determine from Google's docs if an ASP will allow you to change a master password or not. Or if it could be used in the place of a master password. It seems like it can only be used through apps that utilize Google APIs. Does anyone know if one of those APIs allows for changing of the master password?

A quick search shows that others share my concern about ASPs:

Not quite the same as two factor auth (almost the opposite in fact), but I was extremely annoyed when gmail started relentlessly asking me to add a backup email address for password resets. Had the author not had an insecure backup email address, this wouldn't have happened either. Of all the passwords I'm likely to forget, gmail ranks near the bottom. The password to login to who knows where to get the gmail recovery email? The top.
My bank has a password - I never use that one anywhere else, but sometimes the bank calls me out of the blue to confirm some actions / bigger transactions and then I need it.

Turns out, when I can't remember it they tell me the first 2 letters!

CompTIA ISS-001 Exam Practice with Questions and Dumps
This is a great point, and I wish some of the executives as my previous employers understood this. For awhile, things seem great. The company has a core product that is showing great growth. That in turn leads to even more ambitious goals. The value from the above allows the company to offer generous perks. Life is good.

Then what happens? The core product begins to plateau. Executives begin to abandon long-term, ambitious projects, in order to squeeze more juice from the lemon to hit quarterly goals. Finally, perks are cut because it's just way too lavish to have free soda when you're only growing profit 33% year over year instead of 100%. As the OP indicated, the employees are no longer left with any stories. You may still enjoy your day to day work, you may still be well compensated in terms of salary. But without that intrinsic motivation, it's only a matter of time before your enthusiasm flags and you're looking for another job that can offer you what you had before.

For company leaders, products plateau and nobody is successful all the time. But goals and perks are under their complete control, and especially for the latter, it usually requires only as nominal amount of money. It can mean all the difference in retaining your talent during bumpy times, or having everyone abandon ship because they feel abandoned already.
There seems to be something funky with "application-specific passwords" (ASP) on Chrome. Let me explain the problem (that I documented to a friend ~1 month ago): I just revoked all Google Chrome keys, cleared out all of my history / cookies / passwords / forms, etc.

I went to a different computer that had previously had Chrome synced using ASP, switched to my account, and went to settings. At the top, I get this error message: "Account sign-in details are out of date. Sign in again" That's good since ASP was revoked. But then I go down to advanced settings => passwords, and they're all still visible?!?! That's just WRONG! If the ASP login credentials have been revoked, access to all locally stored passwords need to be revoked too! ﻿

Any idea what's going on? This seems like a flaw. The 2-factor authentication is still great though.

With our current understanding of physics, it doesn't seem possible but the key word is current. Scientists recently measured particles going faster than the speed of light. Granted it was not much faster and is still not verified, but if that's possible, it'd stand to reason that there could be other advancements that could do it. If you asked anyone a hundred years ago if they thought they could have real-time communication with someone half way around they world, they would think you were crazy.
"Encryption and backup. [...] If people did these things correctly, hacks would rarely matter [...] This is a field that is ripe for system-level disruption"

Encryption and backups set in stone. An attacker may not be able to read your encrypted backups, but if he can delete them, you still won't be happy.

I think the only feasible solution is that of online, write-only backups. They need to be online so that devices can backup themselves when they deem that necessary; you cannot trust users to do any manual backup task. They need to be write-only because, otherwise, with online backups, an attacker could wipe all your backups. Semi-write only, in the form of "deleting backups older than a year" or "delay any deletes by a month" (to give the user time to report his phone to be stolen) or "delete only after three-factor authentication" probably is acceptable.

"perhaps because the business models of companies are now so dependent on reading our information and selling it back to interested parties"

I think it is because online backup looks too pricey. People keep comparing the price of online storage to that of hard disks. For example Dropbox is about $1 per GB of storage per year. You can buy a SSD disk or a laptop for less than $1 per GB of storage. As this example shows, current solutions also do not protect well against attacks.

I am not sure that the options of having your own cloud, or of making a cloud with others (peer-to-peer backups) will make sense to Joe consumer. Users may not want yet another device at home, likely will not have the upload bandwidth (yet), and are a risk factor with respect to operations on such a device. A home device probably would have to be a custom device, not a PC. Users cannot be trusted to operate it in ways that keeps their data secure, so you must make it impossible for them to operate it.

I still wonder what exactly they are proud of. Of not accepting MasterCard and AmEx? Is it some achievement one should be proud of? I should then be twice as proud as they are - not only I don't accept non-Visa cards, I also don't accept Visa cards either!

Really, with Visa budgets one expects they could hire somebody to express the same sentiment in a comprehensible manner that doesn't make everybody seeing it go "WTF?!"

It rubs me the wrong way that you're asking everyone to follow you. It sounds like you're just trying to get your follower_count up.

I think a better idea would be to create a thread asking everyone to post their twitter handle as well as a quick synopsis about themselves. This way, everyone can quickly read through the list and follow any interesting personalities that they see.
Actually, as the "line" consists of the orbiting satellites acting as relay stations, it is very much shared with the orbiters' own science missions.

Most of the time the link is going to sit idle; an orbiter is only overhead a few times a day, a few minutes at a time. So there will be scheduled bursts of communications. AFAIK the Curiosity-orbiter bandwidth is about 2Mb/s, and the highest-speed orbiter-Earth link is up to 6Mb/s (that of Mars Reconnaissance Orbiter--MRO has returned more data than all other Mars missions combined.)

Curiosity also has two antennae that allow direct communication with the Earth (when it's over the horizon) but they are too slow (hundreds of bits per second) for heavy-duty image downlinking.

I'm kind of wary of the ASP. It feels very backdoorish. And by the very nature of ASP, it is meant to be saved/stored on the computer system.
If you ever had AmEx (I do) you already know that, a lot of places in US and more in Europe do not accept AmEx. When I go to some place I don't know I usually take AmEx, Visa and Mastercard - one of each. It can be very useful in all kinds of weird situations - like when I had some ticketing machine in Europe that was sure every Visa has a chip and a PIN code (American ones of course do not) - but it gladly accepted AmEx without any codes. So variety helps :)

So, I'd say it indeed may be a good idea to have a Visa card - along with their competitor's cards.

Remain Clueless
I never understood perks. I work where I work because I like the people, the technology, and the product in that order.

The lack of money and success create anxiety, but an abundance of these in terms of what an employee can hope to achieve do not influence my decision about where I work.

As for perks, I don't care about trivial asides that people think up in order to retain talent. This is an artificial device that will not stop the bleeding. Don't waste your time doing this if it's something you have to think up in order to achieve yet another metric. If you're going to do something fun do it because you want to do it because you yourself would enjoy it and know that at least a few of the others on your team would too. But then you're not doing it for retention, you're doing it because you want to.

Bottom line is if the factors don't add up, an employee will leave, but things like people, technology and product are what candidates should consider before they join, and they're not likely to change much over the duration of an employment, so if someone is leaving, they probably didn't know what they were getting themselves into, something big changed, or they think they are really failing.

Or maybe they just found a new thing that interests them, in which case let them go.
I also agree. Isn't it against the ethos of hacker news to post links that require being logged in?

Yes, I do. Checks are a more tried and true technology, for one, and check verification is a relatively open technology; we know it's weaknesses. On the other hand, there is no guarantee passwords are even hashed, that backend communication is encrypted, that the horrendous security questions allow easy access to anyone who knows my mother's maiden name (which is a matter of public record). Finally, I can chargeback/cancel/reverse checks, which require a physical item, but though the web interface I can initialize a on-reversable wire transfer.

So I do trust cheques more, and I have more options if a bad check is charged.
Github recently shared some of its secrets on this topic[1]:

"We've gained 100+ employees in two years and we've never had anyone quit. That won't last forever, but I think it's a good indication of the type of company we've built. There are certain things you can do to retain employees, and by worrying about employee happiness you'll ultimately create a much better product."

true, though it's unlikely that you would launch a DSL. far more likely that a lot of the code being generated is lookup tables and the like. engineers that write this sort of fault tolerant related code will do a lot of things the 'dumb' way because it's often less error prone or easier to trace failures. a number of friends work on space related things, and there tends to be an emphasis placed on not being overly clever (i.e. practices like return values being true or false rather than enumerations, etc)
Sounds a lot like Guy Kawasaki's MAP: Mastery, Autonomy, Purpose. From http://hiring.monster.com/hr/hr-best-practices/workforce-man... :

"First, the most powerful way to enchant employees is to provide a MAP. “M” stands for mastery -- that is, a way to master new skills on the job. “A” stands for autonomy -- so that employees can master new skills while working autonomously and not be micro-managed. Finally, “P” stands for purpose. Employees love to master new skills in autonomous positions while working towards an organization with a high purpose such as making the world a better place."
I can't figure out from the article, do you gets goods that are worth around $35, but chosen by someone else, or do you just get 'something' chosen by someone else. I mean, can I get a piece of lettuce in the mail, having paid so much money?
I would say, the price difference adjusted budget of NASA is also much bigger than that of any other nation. Do you see the Russians walking on the moon or driving nuclear cars on Mars?
Same here. There's no amount of ping pong or free soda that will make me put up with a bad team, bad management or lack of purpose I can care about.

I also hope that a good PC with good monitors and a decent desk and chair should not be considered part of the perks.
