The only bump in service we had was ~30s of downtime when our multi-AZ RDS cut over to the failover instance. :) I think we lucked out a little bit...
Reddit downtime usually is late at night or for a relatively short time. This is Saturday afternoon, and it has been down for over an hour, so I'd consider it noteworthy.
Heh ... I have one too. I spent pretty much all my time trying to graduate. With the exception of my first year ... now that was fun!

Some days I feel a bit demented. I was certainly sharpened but the experience feels a bit like opening Pandora's box. Anyone else feel like that?
I don't buy it. I just moved here from China a couple of months ago, and if anything I'd say 70% is an overly conservative estimation of IE usage. Both of my banks, for example, were accessible only through IE with an active X plug-in which made it impossible for me to check my balance on my mac. The same was true of many, many other sites. Much like the US was 10 years ago, only really hard-core geeks were likely to have firefox or other alternative browsers.

As for usage, I also don't buy that. Most people in China are online primarily through their phones, but in first tier cities (which is still a gigantic population), people have bandwidth that most Americans could only dream of. Youku, for example, streamed 5 times the hours of video content as all of Youtube last I checked. And Tudou (which it is merging with) was a competitor on the same scale! In terms of page views, I'd be shocked if Amazon had as many as Taobao. No US news portal approaches QQ. Actually, Tencet (owner of QQ) is considering buying Yahoo!. The only way in which China's internet is small is in the amount of money its users want to spend on content.
Apparently not, using the protocol 'googlechromes' will open the page using https.
Our entire team was making sure we'd give immediate response to any user who asked what was going on while we didn't have the down page up, so most people were pretty happy:

College Students and Their Smartphones
About an year ago, when the story blew up about the Facebook app sneaking through your phone contacts and adding friends numbers' to your Facebook account. I instantly deleted the Facebook app from my Android, and told my friends Facebook was clearly not reliable to have an app privilege on your phone. I called it that they would eventually do even worse, if you let them have an app in your phone. The general consensus was that I was an alarmist doomsayer extremist exaggerating over nothing.

Well, who is crazy now? :) And I repeat what I said before. If you don't delete your Facebook app. They'll keep pulling stunts like these over and over again. It's very clear from their history that they have extremely little care for customer interests.
Were you in us-east-1? That sounds amazingly lucky. If only Amazon would tell us how many AZs actually went down...
An ALIAS record is just an internal-to-Route-53 mapping "when people ask for X, pretend they asked for Y instead". This is conceptually similar to a server-side CNAME. The reason these don't have TTL is because users don't see them.

The returned record, of course, has a TTL, and the ALIAS mechanism will not alter the TTL of the aliased data, so in the case of an ELB you are talking a TTL of one hour. There are no magic bullets to the distributed cache expiration problem.

(The other comments in this article about TTL seem quite confused, though, so this explanation might not actually have helped. Even if you have a 20-year TTL, you are going to see changes immediately from clients that do not have the data cached anywhere on their path to the origin.)

(In particular, there is no difference at all to switching the ALIAS record out for an A record with regards to your TTL: if the user has the target of the old mapping cached they will use it, otherwise they will get the new one. It isn't really "getting away with" that behavior, and it isn't sue to Amazon's DNS being special.)
Yes, yes, and yes, however I believe one of the primary reasons why the academic culture in the field of biology became toxic is that it had become a common practice to have multiple authors in a publication. Initially the practice was quite benign because many experiments indeed require expensive instruments and knowledge of some quite specialized skills, however, this practice was kept unchecked (there is no real penalty of any sort how many authors you add to the paper, except that some authors themselves may object to having to share credit), which allowed for cliques to become established where you basically have a few "friends", and you try to add those friends to every paper you publish for some very minor help/advice they offer, and your friends in turn try to add you to every paper they publish for very minor help/advice from you. This has become an effective method to boost publication count and thus ability to obtain funding without doing any real hard work.
'just because' doesn't seem like sufficient justification for spending 4-6 years working crazy hours for scant pay. It's a big sacrifice, so as other have alluded to it is important to think hard about your reasons for getting into it.
With Government Backing, China Close to a Netflix-Like Video Subscription Site
I've avoided installing any facebook mobile apps out of fear of specifically this kind of thing. I'm much more comfortable keeping it quarantined in a web browser, away from my real contacts list, even if that browser interface is comparatively sluggish and unusuable.
I think we all knew this already. But now now does this article count as startup advice? If so, do we not take it seriously either? In all seriousness though, we should take startup advice with a grain of salt but at the same time realize that while most of it is contradictory that doesn't mean it's all worthless. The trick is to pick out what applies to your particular situation. If there are two conflicting pieces of advice that apply then you just go with your gut. Only you know what's best for your situation. It's always useful to learn what others think or have gone through. So yeah, it's all a bunch of feel-good contradictory stuff but it still has its worth. You can compare it to self-help which is often worthless but even then at least self-help gets you moving toward bettering your situation just like startup advice. Startup advice is like a very useful worthless thing. Yeah, it's both of those things at once.
It's very "hard" to anticipate this, what can I say...very "hard".

I saw the same across all of our Ubuntu servers. Some running Tomcat others running SmartFox Server (a java based game server). A reboot + app restart fixed it.
In most contexts, Disaster Recovery is not the same as High Availability is not the same as Fault Tolerance.

So, in this context, if your devops crew is on the ball, then the first warning in this article:

The only way to ensure close to 100% up time is replicating your entire infrastructure. Infrastructure costs will more than double ...

is mercifully untrue in the majority of cases.

Why? Because unless the major component of your infrastructure cost is storage, or your Recovery Point Objective (RPO) is zero, then database log shipping and bulk data sync to another region isn't all that expensive.

The author may be assuming that you'd need to have the VMs ready to go at the standby region. This isn't true, not when you can boot a large application cluster and promote/upgrade a database replica in minutes. For the majority of businesses, a realistic Recovery Time Objective (RTO) is on the order of minutes to hours, so this is fine.

I built this recently. A booking system for an airline. Works as intended. Failover time is under five minutes. Enabling this is repeatability of deployment, which is an outcome of careful tooling. The application itself was developed by an agile & TDD-centric team which made for an easily transplanted app.

Agreed, at the time we were quite confused and still are about the intricacies of TTL. Sucks that there's not really a good way to address it. Maybe just keep the TTLs at 300 always?

This is very cool. I love to see the general trend of bigger and more expensive science being bucked here.

In general, though, we're still chasing the long tail of knowledge. Nobody's going to build a cutting-edge particle collider, space probe, or Inca ruin in their spare time.

Arguably microbiology is a lot more like computer science than other experimental sciences economically, at least in certain respects; for example, once you've got something interesting, you can probably execute a fairly cheap reproductive process and get a whole bunch more of it. (Well, this is cheap compared to reproducing a particle collider, at least.)

Fun to think about.

To quote Terence McKenna, "You have to take seriously the notion that understanding the universe is your responsibility, because the only understanding of the universe that will be useful to you is your own understanding."

We're never going to learn the absolute truth from reading startup advice, but even if absolute truth did exist it wouldn't do us any good. If nothing else, embracing uncertainty at least lets us learn what we're supposed to be paying attention to.

They have to allow write access to some applications otherwise there can be no third-party address book apps. If there was such a permission, you can bet that facebook would have asked for it by default. You can also be sure that hundreds of millions of people would have granted it and we would be seeing the exact same problem.

The root of the problem is facebook. The important questions should be directed at facebook. We can look to Apple or Google for help, but ultimately when we install an application, we grant it our trust and Facebook routinely tramples all over it. Turns out that it's a winning strategy.

This is not 1945.

This is what I think would happen if the events of MC2002 were real:

If an entire fleet and more than 20000 people were killed in a single day of combat, I bet that the US would have a significant political turmoil, much worse than that of Vietnam, and massive protests. Moving an entire fleet to replace the one lost, could take months, hundreds of billions of taxpayer dollars, loss of morale in troops, and an economic disaster (the markets would simply tank to the lowest).

And of course, moving a fleet to replace the one lost, would mean that you have to lower your guard in another front, which itself introduces new kind of problems. Just as an example, moving the 7th fleet would pave the way for China to invade Taiwan. At the same time, China or Russia would be selling more equipment to the other party.

Right-wing groups would ask for a full retaliation, or more possibly, asking for allies to get involved, but that could rapidly escalate to a regional or global conflict, as other countries would try to support the one playing "David" here.

At that point, with the markets falling apart and clamoring for heads to roll, it would simply be unfeasible to continue.

There's even the possibility that some allied economies (Germany?, France?) would probably refuse to help, as the balance of economy tips in their favor, while US markets tank.

Wars are not only resolved with bullets today.

P.S. It looks like a Falcon 9 uses about 25000 gallons of kerosene. Assume everyone drives Priuses and gets 50 mpg while driving a reasonable 18000 miles per year. A Falcon 9 launch burns less fuel than less than 100 people do in a year of just living their boring old lives.

Rocket launch pollution is pissing in a metaphorical ocean.

If we were willing to accept SSDs being as unreliable as human memory, we could increase capacities by an order of magnitude with current technology. In fact, if SSD controller design weren't so tricky, someone would have taken advantage of this already to build a pretty decent enterprise-scale caching system.
We tried that, but 1) it conflicted with the `gray text` coloring (although we could'be blended the colors together) and 2) we just thought it was less intrusive this way.
We didn't want to conflict with the graying of downvoted comments. :)

That's true. I'm not saying there won't ever be any geopolitical problems wrt energy. Just that these tend to be easier to solve since with electricity you tend to get your power from a large portfolio of decentralized sources, including many that can be exploited locally pretty much anywhere in the world, while with oil, there are fewer sources and you can't really substitute as easily (right now transportation needs liquid fuels, so you could have all the wind power in the world and it won't help you).

I guess a good real-world example of what I'm saying is: Right now, we're not really seeing big crises and wars about electricity, and I expect that it will continue in a similar fashion in the future, with or without EVs on the grid.

This is about the other side of things. Everyone who had you as a Facebook friend and does still have the app, is now sending you emails that you're possibly not receiving. The problem is worse than you make it out to be. Deleting your whole account and manually telling people your email address was the only way to prevent this.

I know its a limited view of reality, but I was debugging ffserver, found the bug and mentioned it on FFmpeg's IRC channel. Michael added my own one-liner change and listed me as the author for the git commit. This is a GREAT feeling for a newcomer to a project and it makes me want to keep helping with FFmpeg.

I agree with the author of this article in that FFmpeg will eventually win out, just for little things like this.
Thank you! Was banging my head against the wall on RHEL6's tomcat. Went on Hacker News to stop thinking about it for a few minutes. Son of a bitch, the solution was right on the front page.
Apple charges way more than market rate for storage and memory upgrades. A stick of memory that costs $40 on Newegg might cost $200 from Apple.

In the past the sensible option was to buy a Macbook with stock memory / storage and upgrade it yourself, but of course that's no longer possible with the rMBP. Still, that says no more about the actual cost of SSDs than the price of a hotel room says about beds. :)
Even if you're not running java in your stack, it's worth a quick check on your servers. Our SoftLayer servers use an Adaptec RAID card and the monitoring software uses the JVM and will suck up all of your CPU. All of our MySQL/Cassandra/Redis/Kestrel servers needed to be bounced because they had RAID cards. Frustrating.
> you're not going to take down PeopleSoft by trying to sell companies a PeopleSoft replacement. Rather, you're going to build something like Expensify that saves individual employees from some of the more irritating things they may have to do with PeopleSoft.

Brilliant way to put this. The way to compete with old enterprise software is first by not doing it the way they're doing it. I would start with something that appeals to individual employees, make their work easier, even joyful, and eventually you'll work up to top level decision makers.

By then you'll have a fantastic user-centric product and a list of features an exec team would drool over.

Is this related to jgm's HeX[1] at all?

I saw this on my Fedora 17 laptop. Chrome started eating up 100% CPU and my laptop started getting really hot. I tried restarting Chrome, updating Chrome, etc. Nothing worked. Rebooting fixed the problem.

Surprisingly, none of my servers have had problems, but I don't run Java anywhere.
For my blog, static files (anything stored in an app's "static" directory, basically[1]) the like are handled transparently through django-storages' S3 support [2]. (The STATICFILES_STORAGE option in settings.) If you’ve used Django's staticfiles framework before, it’s pretty much plug-and-play.

For more dynamic file storage (say, using FileField or ImageField in a model), I believe django-storages would work, too. (Make sure you configure django-storages with the DEFAULT_FILE_STORAGE option set to S3 also.)

Assuming you’re managing your site via a local dev server (or a server that "hosts" the "hot type" version of the site), any time you "upload" a file to your local server, it'll actually upload to S3 (and any calls to "field.url" will actually map to the S3 URL). Not sure how well it'll work in all use cases: I haven't actually used FileField or ImageField myself in the django-medusa+django-storages usecase, but I have used both separately so I’m fairly sure this is possible.

This is a pretty darn good question though, so I’ll likely make a follow-up blogpost with a more comprehensive walkthrough regarding handling staticfiles and FileField/ImageField. Sometime in the near future.

Multiple sites/subdomains is a bit more complicated. I’d say you should probably use separate Django instances for each and render them separately. (For S3, you’d need to use separate buckets, anyway.) If they need to share data, you can configure multiple Django settings.py configurations for each site but still use the same source tree and local database. (See the Django sites framework: [3])

Getting into the machine learning/NLP business
I'm working as a web software developer but I'm really interested in the Machine Learning and Natural Language Processing fields. I've begun self studying(I took the ML class from Stanford) and I'm playing with the idea to start a business using this technologies.

The point is that I don't know how to start, what could be the potential clients and market, how much knowledge would be necessary to get clients...

There are a lot of stories in HN about web applications, but I didn't read anything about this kind of companies/startups, maybe because this technologies require building personalized solutions instead of the one to many from most startups.

I think that the path will get clearer as I keep reading and getting practice, but I'd nice to know some experiences from another people with similar interests.
