@tptacek You aren't listening, you're getting all hot and bothered about a claim you keep hearing that I'm not making. I don't think that professional design is important for startups.

It's a bit much to obsess about semantics and then throw your hands up in despair that people make the kinds of distinctions that counter your points.

Who, exactly, is saying to you that "only professional designers can create sites that will pass muster with buyers in the real world"?
In .ssh/config:

Host alias

Port alternate_port
> I do hope one takes the vigilance to set a port number sufficiently high up, and sufficiently random looking

Hopefully not over port 1023. If a user gets on the system and crashes your ssh daemon through OOM killer or one of many other methods, that non-root user can then restart its own daemon and listen to that port that you put >1023 'for security reasons'.

Accidentally answering yes when it says a new key was detected is all it takes to get keylogged.

I'm not sure about this. If we say FB offers $600M, and Instagram is holding out for a billion, it wouldn't make sense for Instagram to go prove that it's only worth $500M (valuation), right?
Yeah I'm not a dog owner but I've had to watch dogs for desperate friends before, who find themselves having to take sudden trips without a way to care for their dogs.

Actually, the more I think about this, the more it seems like an incredibly good idea. To be honest, it even seems to avoid some of the negatives inherent in the airbnb model (nobody's going to turn your dog into a meth lab, for instance).
Thanks for the feedback! Both of your grievances are legitimate issues. The reason why we didn't support those use cases on iPad is because they are power user features.

I wasn't singling out any particular languages, just giving an example. It's a lot easier to understand code in an unfamiliar language if it's written in an idiomatic fashion as opposed to using all sorts of tricks.

I remember I would beg my dad to drive me around on the weekends looking for garage sales to find Commodore 64 software. Sometimes we would get them by the box full, on unlabeled floppies, and spend the whole weekend trying each one. Every once in a while you found a disk filled with a bunch of games. Good memories.
> only figures since the major use of screen was to enable this functionality over ssh.

Exactly - I don't understand what Mosh provides that GNU Screen doesn't... what problem is it actually solving?
Honestly I'm actually getting really bored and annoyed with the amount of Twitter Bootstrap sites now, that don't change themselves at all.
Sending these emails drive down your domain's mail open rate and CTR[1], so it probably makes sense not to send those from that perspective.

1: My best guess is that if a user unsubscribes from a list, they aren't likely to open the subsequent confirmation email. If they are likely to open the email (use an A/B test to find out), then it probably makes sense to continue sending these emails, because there isn't any harm in mildly annoying a user that's decided to leave your app anyway.
Because I'm not an active web designer, I'm not even really familiar with what Bootstrap sites look like. You're making all of these assumptions about my background and motives. The site looks generic (based on experience gleaned from looking at lots of sites, rather than participating in some kind of elite designer cabal), the spacing is cramped, and the type looks bad. Putting something on a grid alone doesn't make it look good.

Since you bring it up, the top photo is fine but especially the photo of the desk looks quite poor. But hey! Still not suggesting that matters to the business's bottom line!

I haven't told anyone not to launch, I haven't said it's important for startups to look professional, and it's still true that Exec's design is a bit crappy and unprofessional.
I know? I'm not sure what you mean, I agree with the great-grandparent post and was trying to elaborate on it.
> especially if the company that wants to use it is a big enough company to have a budget to sell 20,000 calendars.

This is what I don't get. The budget for the images— the reason people would buy the calendar in the first place— was so outrageously low.
$3.4 million is pretty chicken-shit to invest in a business. I know a brewpub that opened with more than $2 million and being a restaurant, it doesn't' have near the upside potential.

It also seems that spawning happens only in the top left section of the canvas, which makes that area especially crowded.

It's a bit too easy to get killed right after spawning; maybe there should be a very short grace period in which you can start moving, but can't yet kill or be killed.

Regardless, it's a very fun game. Thank you!

We look up, never down.
I figured this out while I was driving down the street next to the downtown trail where I run, and I tried to point out to my passenger how going for a run is always a great reminder that I'm a slow, fat, horrible slob. I say "tried" because at the same time I was saying it, I realized it wasn't true, and I couldn't even twist it in a way that reflected the truth. The only truth in it is that when I go running, everyone on the trail who is slower or fatter than me is invisible.

I noticed instances of this much earlier in life, but I didn't generalize. When I was a little kid playing Little League, I only compared myself against better players, so I was always the worst. When I was in college, I lamented to an old friend of mine that no girls had liked me in high school. He mentioned a few names, asked what about them, and I was irritated with him: What do those girls have to do with anything? The ones who mattered didn't like me.

I've always been criticized by my parents, my teachers, and my therapist for being too harsh on myself, but looking upwards seems more optimistic. I don't want to look downwards. It's scary. Plus, every mountain biker knows that your bike goes where you look, so you look at the gaps between obstacles, never at the obstacles themselves.
Brilliant editorial re-post. Let's wait for the comments to catch up. And bookmark this thread so that 4 years hence the Instagram folly can be made plain. That's the great thing about the valley - there are always more 24 year olds arriving.
I'd argue the real problem here is that too many people are taught to rely on shared mutable state in concurrency. Mutable state and concurrency mix very easily as long as you stick with something like message passing for your cross-thread communication. Erlang stands out as a stellar example of how successful that approach can be, but it can just as easily be done in C. Event-driven and client/server programming, as close cousins of the Erlang model, are concurrent even when they aren't parallel, and have given us a couple decades' worth of proof that good programmers don't really have a problem with it, and even mediocre programmers can manage it. The point where everything really gets hairy when the word 'lock' gets introduced into the mix.

If we take, for the sake of argument, that the primary motivation for writing parallel code is some version of scalability or performance, then I don't think we should be so hasty to jettison mutability. After all, concurrency is only a means to an end. The real goal is performance, and it's generally much easier, if not more possible, to write performant code if you allow yourself some mutable state, however judiciously it is used. The hash table example from my earlier post is an elephant in the room here: Hash tables can give near constant-time performance. The closest anyone has ever gotten with a purely functional equivalent is O(log n) plus a healthy dose of cache-unfriendliness to boot. If that must be the cost of pervasive parallelism, perhaps we should be reconsidering how pervasive parallelism really needs to be.
The Instagram-Facebook backlash?
I am actually wondering if the value was too low. They are crossing the chasm so to speak and moving toward mainstream very quickly. I don't know where they would have ended up, but if they could have negotiated an upround with the founders and VCs taking some cash off the table it may have been a better move.

I fully understand that if I had a $1B offer for a company that I would literally be sick turning them down, but the potential was there for something really big. If I could keep going with $10m in the bank, I would like to think I would try.
I'm just pushing back on the word "unprofessional". I care less than it looks like I do. :)
This architecture went far enough to get them acquired for a lot of money, so while it may not be a miracle of ingenuity, it's worth studying as an example of something that worked.
It isn't the photo service: Facebook. Flickr. Picasa. Imageshack. Twitpic. Imgur... To name a few.

Instagram doesn't have more users than Facebook. Hell, it doesn't even have more users than Flickr (51m) or Photobucket (50m).

Instagram is a small part of the web photo ecosystem.

It's a very peculiar play by Facebook, and not at all comparable to Google & YouTube other than the fact that Google acquired YouTube, and Facebook acquired Instagram. Instagram represents a diversification of Facebook's offering, and one which says "it's cheaper for us to spend $1bn acquiring Instagram than it is to make a compelling mobile photo app to usurp them".
The Rat Race
I love this idea. Yet, if I were the founders, this is the issue that would keep me up in the night, not just for what could happen to the pets, but for what could happen if a dog bites a child. I don't think the site is for every pet owner, but with a $4 billion US market in pet services and plenty of pet owners who hate kennels, I think there is sufficient demand to make this a success. It will be interesting to see how they offset the risks.
Reach out to known travel blogs with a well drafted summary of what you offer. Attach some promotion to it. If you plan to charge, than offer a discount to readers with a code that references the website that is blogging about you. If you do not charge users, than offer private beta access to the first n readers to sign up with that invite code.

There's a pretty big chicken and egg problem with this, in that to make it useful you need a lot of users in each travel destination to make this work. If you're active on CouchSurfing, I would try to find locals in popular travel locations who would be interested in giving it a try, or maybe work out referrals with hostels to promote your site locally in exchange for promoting their hostels on your site. For example, for every 100 users they refer, they get 1 week of free advertising. You might even work with Hostel World to drive referral traffic to them with the hostels you've made agreements with in exchange for some free advertising on their site in a similar manner.
Any idea on what caused it?
As a direct answer to the question and based on the problems the author raises, OS X's "Automator" is just that. It's casual yet still pretty powerful automation/programming. It loads fast, it has a visual IDE of sorts, and it can do a lot of jobs you'd otherwise use shell scripts for.
Thanks for all the answers everyone, I get it now :)

Gizzard is sharding framework that sits on top of, as a separate layer from, MySQL (or any other storage backend, like Redis). It's open sourced right now at https://github.com/twitter/gizzard. Twitter's MySQL fork for now is just a way to get in bug fixes and extra features that are needed but not available upstream.
It's a fork in the sense that we're developing without an immediate requirement to get MySQL/Oracle to accept our changes. We hope they will accept the changes, of course, but it isn't and can't be a requirement for our own progress.

I set it up for that exact purpose. I'm using irssi on a remote server and it's annoying to reconnect every time I connect or disconnect from VPN.
For now it works great.

And yes, having an Android client would be super sweet.

I really hope this becomes popular.
It does raise the question of whether you even need any real ingenuity on the back end for this sort of startup...
I think Moore's law can help to an extent with approach 1, especially the protein folding bottleneck. We also need better computational techniques, taking more from dynamical systems maths for example.

I think approach 2 can also inform approach 1. Especially if grey and clearbox models are used - probabilistic graphical models, markov logic networks even genetic programming. So instead of using them for just prediction or a distance metric, we study the patterns in the models they produce. For example, instead of merely fitting a bunch of weights in some sum product model, one could use genetic programming where the primitives represented actual computations from a simplified model of cell dynamics. So while not guidance it still offers some way of embedding some intelligence in the search.

Micro vs. Macro Perspective
I think all of the changes pretty much do apply generally, but for us it's easier to go ahead and publish publically to be able to pass these changes upstream, rather than pass them off privately and wait potentially a year or more to get them back in a public release.

We want to be able to collaborate with Percona, Facebook, Google, MariaDB, etc., on some of the actual changes, to make things better for everyone. This is the first step towards that goal.
If instagram was a threat to Facebook why didn't google snatch them up? Oh that's because they aren't .... I have no idea how instagram I worth a billion dollars I've never used it and alot of peeps I know don't... If you think about there hasn't been any real innovation since 2007 and do I date say it that was twitter... What has come out sense then that makes you go wow? Nothing... Technology is dead ...

Have to wonder if it's due to a conflict of interest – Arrington may become more involved in TechCrunch now that Arianna Huffington isn't his boss. He and MG Siegler are already set to make an appearance at TechCrunch Disrupt.
User ratings, if done correctly, will make the site "sticky", so if they build their user base fast enough, they could have a first mover advantage. Even so, social networks supposedly have a first mover advantage and even those die off as improved user experiences are presented. It sounds like several of these dog sites have launched in the past few months, and the winner will be the one that makes the best user experience while building volume of users with polished profiles and ratings that seem real and credible.
I was thinking more along the lines of working around data-locality issues. For instance, imagine that you have code that requires very high latency fetches, or you are working with a data set that doesn't fit in memory. Typically, you have to develop modified algorithms that for these scenarios, but there is no reason that a minimal fiber scheduler couldn't adapt seamlessly. Even better, if your conditions change (like for instance, mobile devices moving from low throughput to high throughput links) a scheduler can adapt, but the hand rolled algorithm must be re-coded.
It just looks like YET ANOTHER TWITTER BOOTSTRAP SITE. It might be the fact that I've had a headache for most of today, but it feels like every fucking link I click on nowadays is an un-tweaked Twitter Bootstrap site. It is so annoying.
Multiple accounts / personnas on mobile devices is coming soon. Your work will not need root access, they simply get an "account" on your phone, with separate email, file system, web browser history, etc. I wouldn't be surprised if Android and iOS implemented this in the OS even.
Wow that is an awesome article, so one wonders if a fund is nearing its 10 year expiration, can they spend the 'reserve' on a fast exit like this?
I'm not convinced Yahoo buying Facebook for $1 billion would have been a good deal for Yahoo. Yahoo never would have been able to make Facebook nearly as successful as it is today. I have my doubts Facebook would be worth even a $1 billion today. Yahoo has an awful track record of making the worst out of their acquisitions and I don't see how this would have been any different.
I think the point that everyone is missing here, is how heavily integrated Instagram is in non-Facebook social networks (i.e. twitter and Flickr). Yes, part of the valuation was due to Instagram being an up and coming social network. But the main value of this acquisition comes from the fact that, with this single purchase, Facebook is able to leverage multiple social network's userbases into their own.

From captain Zuck's post on Facebook "We think the fact that Instagram is connected to other services beyond Facebook is an important part of the experience." (https://www.facebook.com/zuck/posts/10100318398827991)
Yup! And our changes are quite complementary to Gizzard, since it's one of the larger use cases at Twitter for MySQL. More to come in the future to better support big Gizzard systems!
Interesting. I feel like the only good scoops most of the tech blogging sites now have is about internal drama and much less about awesome M&A type news.
The binaries built by the Android NDK are emulated on the emulator properly. I've deployed NDK binaries on the emulator and traced it with IDA Pro, one line of ARM assembler at a time... So yes, it's a proper emulator.

Just a fact I thought you might find interesting.

I don't, but two things have happened that I can see.

Michael Arrington posted on TechCrunch a week ago and is helping out with a new TechCrunch event: http://techcrunch.com/2012/04/04/im-back/

Today, it was announced that CrunchFund invested in rover.com: http://www.geekwire.com/2012/crunchfund-madrona-bite-doggie-...

Not saying either of these things are connected to the split but there's clash potential in them, I guess.

We'll have to study this. The practical reason for using the rijndael reference code is that ocb.cc is only written against three interfaces: OpenSSL (which we can't ship currently for licensing reasons -- we depend on GPLed code), the rijndael reference implementation, and compiler AES intrinsics (which we don't have on most architectures).

Down the road we may end up making a shim to use GnuTLS or figuring out how to ship as GPL+OpenSSL exception.

The practical exposure to information leakage via timing attacks is pretty controlled, since we just ignore any datagram that fails the authenticity check and we generally only send outgoing packets per a timer (whose smallest value is 1/50 second).
No, Vitess is more along the lines of our Gizzard system which has been out there for a while:

Cancer survival rates are a mixed bag with many barely moving at all. The statistics below are based on that for Victoria, Australia (population of about 5.5m).

5 year survival rates for the following cancers has barely changed at all since 1985: Pancreatic, Larynx, Lung, Mesothelioma, Ovarian, Cervix, Central Nervous System.

Although the following cancers have seen much better improvement:

Pharynx, Colorectal, Stomach, Oesophagus, Gallbladder, Breast, Prostate, Kidney, Thyroid, HL, NHL, MM, ALL (basically all the blood cancers).

Overall the 5 year survival rates for cancers have improved from 47% to 64% now. Definitely better, but unfortunately not "spectacularly better".

Of course, these are survival rates, so do not reflect improvements in public health that prevent people from getting cancer (e.g. survival rates for lung cancer have have actually decreased, but less people are acquiring it due to reductions in smoking meaning deaths have reduced by about 50%).

Oh you can define it more clearly, I agree. You can't enforce whatever rules you want to enforce any more clearly. That was my point.

I'm not sure the pitchforks would come out against it, some would, some wouldn't but it's impossible to say since most people who have thought about it are very confident there is no solution in this class. If something can be digitized then it can be shared over the same channels as private communication. To "combat piracy" you need to control what people can say, what people can hear and how people can read. To do that you need to examine everything.

You need surveillance and censorship, because anything that can be made digital is now either no different from protected speech or can be presented like protected speech to confuse the watchers.

It's not great for our artists or our economy that the internet made this a reality but it is. The internet came with a tradeoff for our culture. Large scale calls to "combat piracy" fall into the same bucket as "stamp out communism" or "win the war on drugs" or "stop pornography" or "eliminate blasphemy". Any entity that could do this would either be terrifyingly totalitarian or unable to enforce the rules. So they are either cartoonishly evil, ignorant of the problem and therefore unlikely to help anything or are raising money/political capital using some buzzwords.

So someone has to figure out how to support artists that are suffering through this disruptive change and Netflix is actually in a decent place to try innovative potential solutions. Hence the pitchforks coming out when people hear they have decided to support SOPA-style political posturing. I'm not sure they actually are, this is a Russia Today article, it's right next to a story about mind control weapons that will create real life zombies. This site is famous for hilariously innacurate stories.
