At home, after working on my todo list, I set my E.gg Timer to around 15-30 mins, and go through all these materials in my Google Reader. The best time to clear these materials is when I'm on the move(not driving) or waiting, I can afford a lot more reading time.

Gaaah, knock off the CAPSLOCK and the machismo, please.

Also, you don't need to invent backcronyms for CAR/CDR, they're now called first/rest.

Having said that, I really like the presentation of your blog, nice typography. And after skimming your book[1] in progress, and noting your obvious theoretical bent and taste for rigor, I can only anticipate to read more of your future posts (latch on to something "obscure" like ACL2 and make something fun with it.)

[Edit:

The book has code samples in 4 different languages; LISP (the ancient cap-cased "one"), ML, C, and what looks like Pascal. If you want to learn about the axiomatic specification of computer programs, specially for "structured" programming, then look into the works of Gries and others, specially in the silver "Texts and Monographs In Computer Science" books (the entire series is a feast of delight that should be devoured, and washed down with heirloom, stolen wine):

The Science of Programming, Gries.

The selection Programming Methodology edited by Gries has various approaches to the structured method, with contributions from Dijkstra, Hoare, Wirth, Reynolds and other rock-stars of axiomatic semantics and verification.]
Actually, nowadays, the email is more likely to be read in a timely fashion. Snail mail to congress gets delayed because it's subject to heavy duty security screening before it ever reaches the legislator's office. It may be useful for issues of general concern, but if you're writing about any specific piece of legislation presently under consideration your snail mail may not even reach your representative's office until after the bill has already been voted upon. You're better off phoning.
Maybe it's a version thing, but Ctrl+Shift+T doesn't work for me. Cmd+Shift+T does. But will it restore all the tabs you had open when you accidentally quit?
I gave up Slashdot after a long time because of the predictable jokes, but do miss the genuinely clever ones. If the funny filter could somehow determine the difference between the clever stuff and the memes (or if there were two moderation options to separate them), it might be more useful.
What I find odd is the crosswalks here in DC where there's sign that says "Pedistrian MUST push button to cross." Yet it's not true.

Actually, it is true at some of them. If you don't press the walk button at some of them, the walk light doesn't turn on and the light is on red for a shorter period of time.
Even moreso than that, many of the lights in New York still run on genuine relays. You can easily hear them at many street corners in Manhattan, happily thunking away. (The New York Subway is also still powered almost exclusively by relays, even to do complex things like monitor train speed. It's both impressive and disturbing to see what they were able to accomplish a hundred years ago without modern computing hardware.)
No they cannot be. All the complex processing cannot go to web. The web has to be light weight. Then there are messaging systems and other systems with which integration has to happen
This works incredibly slowly for me (~30 seconds per symbol after I stop drawing), and doesn't work at all on my iOS devices (where I can actually draw reasonable looking characters, unlike with my mouse). Still, it's a really neat app.
Yup planning is hard when the next guy that registers can double your load, but dedicateds give you a lot of bang for your buck and you can still use VPSs (or cloud stuff of course) to scale up in a hurry.

I'm pushing a ton of data (>200m events/day now) through 2 dedicateds + 1x VPS and if it's a bad day I get 1 or 2 extra VPSs deployed, each of which adds another x,xxx events per second capacity.

On further review, I stand by my original statement: Taubes thoroughly misunderstands the issue.
As a dude working at a solar thermal startup, i would be really excited to see this work. OTOH, solar thermal is already about 30% cheaper than photovoltaics, so that diruthenium is gonna have to be replaced by something really, really cheap...

Our tank losses are nonzero, but in the scheme of things, not all that huge, either. So for it to become cost effective, this storage would have to compete with basically water and glycol in cheap, unpressurized tanks.
I've had this happen to me in Chrome a few times recently (I switched to Chrome full time a few weeks ago), but I've never had it happen in Safari since Safari prompts you if you have multiple tabs/windows open.
Interesting... so it seems resume trumps argument at HN?

Well, pile on the down-votes folks, I've got to get back to work.
My honest question is why there is this odd loyalty to virtual environments in this community. I realize that it may be boring but you guys are passing up insane savings that can be had by using colocation. All cloud providers are very expensive when you actually do the math and you need more then 10 servers.

Our example may be a bit extreme, but we are just building out a new datacenter at a colocation and will recover the entire up front investment ( about 150k, we have the cash to not need leasing ) in a bit over half a year.
no keymap is without its annoyances. in DVORAK, ⌘w is right next to ⌘v (paste). i close windows all the time :(
The problem is not that is hard; the math can be done, the necessary capacity can be calculated, servers can be ordered.

The problem is that buying 3x the number of servers (or number of data centers) that you need "baseline", to handle the spikes, is a staggering expense.
Ive recently began doing this as well. Would be interested in talking to you about possible projects and causes you find interesting. What is a way to contact you?
Chalmers was great, and I miss Göteborg!

I'm working at a startup in Boston now. The masters has been a huge benefit to me, though my job these days doesn't exactly relate to the program I was in (Complex Adaptive Systems).

One interesting feature of the master's programs in Sweden (compared to the US) is that most students do their thesis work with industry, so it might be a good match for people leaning more towards business than academia (ie, those who read HN).
No one denies that capacity planning is hard. There are books written on the subject. The points you make are exactly the reason why you need to do capacity planning and plan for mitigating failures. If you aren't planning on 2x (in fact more) growth then I'm confused as to what kind of growth you really expect in your service.

If you aren't giving yourself room for expected and unexpected loads, you're doing it wrong. Add capacity and load testing to your process.
Ask HN: Any students at UCSD on HN?

Clearly the only legitimate comparison is the number of phones activated on Verizon's network. Anyone who feels differently is a sheep who puts fashion and popularity ahead of the only things that really matter and has been sucked into Steve Jobs's reality distortion field.
Brilliant:

"An Earth-like planet — that is to say, one that is the right temperature for water and thus life as we know it — would take about a year to complete a circuit around a star like the Sun."
Not really -- solar thermal already is about 75% efficient. I.e., 100J of light => 75J of heat added to working fluid. My understanding was that this chemical toggles state at the addition of any heat -- not necessarily by the addition of solar energy. But that's just a guess, i'd never heard of diruthenium before five minutes ago either :)
Oops, yeah it's Ctrl on non-Mac and Cmd on Mac. It does restore the tabs.
This is a fair question, so I don't see why it should be downvoted.

The reason outsourcing hardware to AWS or Rackspace makes sense versus hiring hardware guys (usually) doesn't is that you introduce one more link in your failure chain. In My opinion it is far, far more likely that you and your hardware guy are going to mess up ZFS configuration somehow and have it fail when your app gets black swan traffic than Amazon going down. When it comes to Engine Yard, I'm all for that too, in the right circumstances, but you get fairly high lock in. I agree that you get that with AWS too, it just seems more likely that AWS will be around 10 years than it does Engine Yard. But sure, Engine Yard and Heroku are great.
The medieval scientists and practitioners were both rather wrong about what was going on inside. However, both computer scientists and computer engineers have a good fundamental understanding of how their systems work. If we're talking about the process of building them, then yes, I would agree, but I think its more akin to the science of management, and people like Drucker, than medieval phlebotomists.
I lived for three years in Asia without working (Turkey, India, China). My standard recommendation is Kunming, China. You can live there very comfortably on 400$/month. There's a good foreigner community, ultimate frisbee, awesome food, and the environment and weather are fantastic. You can teach English if you want to, for 15$/hour. A great meal at a restaurant costs 4$.

In Asia, finding a shared flat is usually pretty straightforward. Just ask students and other young people on the street. They will be more than happy to help and practice their English. Networking with other foreigners also works pretty well, though living with the locals is a good way of learning the language fast.

Exactly what I was thinking, though I do still enjoy seeing CAR and CDR. But I'm the kind of guy who likes steampunk, and it's in the same vein.

I, too, am looking forward to more posts; it's worth checking out the posts that are up already. Definitely my kind of thing (see my http://copperthoughts.com/p/set-theory-and-lisp/).

This is where I'll refer people who know nothing about Lisp when they complain about it; not too self-righteous, pleasantly informative, and theoretically interesting.
Is it because of the network throughput on the small instance type? I haven't noticed anything nearly that severe with our 20-instance setup of larger instance sizes, but then again we've only run production on EC2 for a few months now...
Yes. The pricing page design is taken directly from github. I have no valid excuse for that. I'm changing it as we speak and sending github an apology for stealing.

It was intended as a placeholder and then I got lazy.
Goddamn it VentureBeat, stop blowing up our spot :-)

Do people really not know that Chrome has an option to reopen itself with the tabs you had open last? Preferences > Basics > On Startup > Reopen the pages that were open last.
Latest chrome (9.x dev) has an option in "about:flags" to show you a kind of confirmation box before quitting.
This is like complaining that he keeps getting a spoonful of Cheerios up his nose every morning because his nostrils are too close to his mouth.
I respectfully disagree that we stole the dashboard design. We were definitely inspired by pivotal tracker bit we didn't steal anything.
In vi, I use control+w to shift between the sections of a split window. You can imagine the hilarity that used to ensue. But, it's not an issue anymore. I haven't made that mistake in well over a year.
really? json is so much easier for me to read than xml. What do you like about xml?
"How is it that a CS major pays tens of thousands of dollars for a degree, and has little to no concept of version control, project roles, design documentation, functional specs, or a bug tracker?"

Simple: this isn't what Computer Science is about! A fundamental misconception about computer science seems to be that is is software engineering. This couldn't be further from the truth. CS is about algorithms: their efficiency, their provable correctness, and their applicability to actual problems. None of that necessitates version control.

Dijkstra said, "Computer Science is no more about computers than astronomy is about telescopes." It seems to me that version control, bug trackers, and wikis are about software, not Computer Science. These things are important, to be sure, but they're not Computer Science.
Typo? : "If the availability drops below 25% you can apply for a service credit equal to 25% of your monthly bill."

- if availability dropped below 25%, I'd be looking for more than 25% back...
There's a free App Store version.
Damn right. And we welcome the competition!
What incentive does Hacker News have to allow access via an API? At the moment, introducing an API would cost YC money because it would take time to develop and it would potentially increase server costs.

However, allowing others to do the job seems less troublesome.

Creating artificial restrictions to _prevent_ other people from doing so, seems like effort.

I would imagine that the owners of a site would only seek to stem the wholesale flow of information to another property, when inaction is likely to lead to a loss in value.

Where is the value in HN? It could be argued that the value lies in the posts and the related combined wisdom, but I think the true value is related to attention and focus. We come to HN to participate. If the content is allowed to spread to third-party applications (via an API), this primary source of value is lost.
I completely agree. I've got some projects that may be interesting to you:

https://github.com/mathgladiator/win (very simple node.js platform that uses CouchDB for models)

https://github.com/mathgladiator/otto (replicating from CouchDB to node.js)
Writing spreadsheets and other tabular data formats for Python is very simple with my Tablib library (http://tablib.org).
hmm, good point, I hadn't thought that this would be for optimization purposes. but is it premature optimization if the css way is fuglier and the js way is fast enough to get the desired framerate on modern browsers? would like to see some stats.
On the offchance you're not trolling: the reason you're getting downvoted has nothing to do with resumes, it's because you are throwing out unfounded hearsay FUD. Come back with some actual evidence for debate, otherwise you're no different than any one of a million irc script kiddies. Anyone with knowledge of such an exploit would either A) keep it secret or B) tell Amazon about it. Casually dropping it in conversation screams wannabe.
Anyone manage to build a Lisp that used semantic indentation (like Python)? You could make it optional and just have it function as a preprocessor that generates the real thing.
Happens all the time! I'm getting my nose moved though.
The premise was that nobody but people who work support higher taxes. It was that people who don't work probably support higher taxes, because they get benefits with no cost to them personally.

It doesn't matter what the TSA does - the fact is they were invented as a response to terrorism. Thus removing them would be an opportunity for an opposing politician to use the attack of 'being soft on terrorism'. I think the TSA should be abandoned - I shudder to think of the lost actual dollars in funding, as well as the lost productivity of millions of air travelers going through a couple of minutes of invasive screening.

As for 'prevention' - many western nations have been victims of Terrorism attacks since 2001 - including the UK and Spain. None of these countries have/use TSA style screening or restrictions. None have had an airline-based terror attack since. That should tell you about the need for the TSA.
On the other hand, in Dvorak, Q is directly above the left ⌘ key (where X usually is), and W is directly above the right ⌘ key (where , usually is). I'm always reminded of this serendipitous symmetry whenever people complain about ⌘Q and ⌘W being adjacent on QWERTY.
I'm becoming increasingly cynical about the way energy "breakthroughs" are reported. It's not the science side - it's great that they've worked out how this compound remains stable after absorbing energy. But you can't present this finding as any kind of breakthrough until they've actually found a compound that exhibits the same effect cost effectively. That they're looking is good. That they now know what to look for is better. But they're still searching. There's no breakthrough.

Let's get real - Ruthenium is about US$5500 per kilogram. You can buy the best lithium batteries on the market for significantly less.
Well yes, but if you have 20+ tabs open in a couple of windows, it's disruptive and time consuming to close and reopen all of them.
I think the Ctrl+Shift+T shortcut to reopen closed tabs works across sessions too.
Similarly, in emacs I use ctrl+n to go down. On FF, this will open 5-20 windows, depending on how long I wait. (I have a very fast repeat.) Pentadacty with emacs bindings has helped with, but occasionally I will hit the key to pass all keys to FF, and once again end up with ~20 windows to close.
Is it valuable to have server on your phone?
absolutely. this is a wonderful thing...i may close a lot of windows, but i don't usually quit the entire program unless i mean to.
That's why for applications that I do not want to quit easily I set "Application (keyboard) Shortcuts" [ OS X ] to require something less commonly used (like cntl-opt-cmd-Q) for quitting. [ OS X System Preferences -> Keyboard ]
This doesn't change the fact that it reminded him of Marx and the Unabomber.

Here's another good interview of Max Levchin with Bob Cringely back in 2005:
http://www.pbs.org/cringely/nerdtv/guests/#l

This is worth watching because it's pre-Slide.com acquisition and just barely post-Google IPO.

The interesting comment to me is his comparison at the time of Google to Alta Vista, specifically how Alta Vista was the huge search engine of its day and then just kinda faded away.
Oh wow. This is big! I've been waiting for this for a long time. It's basically Squid in the cloud, but at a scale you couldn't hope to match with your own implementation. We used CloudFront+S3 to serve all of the static resources for DotSpots and I was really impressed with it.

Some small downsides (not fatal): I'm assuming that it shares the standard Cloudfront minimum TTL of one hour right now. It also won't pass through query strings to your origin servers. You can invalidate items in your cache, but the API is a bit odd (it's designed more for DMCA violations than updating content).

This might also solve some of the issues when trying to serve gzip-compressed content from Cloudfront. You had to jump through some hoops to get this working with S3: the data in the bucket had to be gzip compressed and you had to serve different content to different browsers depending on whether they supported gzipped content or not. Hopefully it respects the Vary: header.
Having worked on tripadvisor's flights product, all I can say is "well, duh."

Seems to me there is room for a disruptive hotel booking startup. A Kayak Explore like interface that included the total cost of a trip (mid-range hotel and cost of a flight) would be killer.

Or even better, one that also offered/priced alternative methods of travel. Here on the east coast, now that air travel has been turned into a massive ordeal and time sink by the TSA, bus and train are often quicker, cheaper and more convenient alternatives.
That's a really good point. This may be telling us something more general about what the cerebral cortex is doing, too.

For example, when people learn a new language that involves phonemes very different from those of their native tongue, they often go through a phase where not only do they have difficulty producing the foreign sounds but have difficulty distinguishing sounds that would seem very different to a native speaker. For example, R and L are perceived as very similar to a native japanese speaker and the nasal vowels of french and portuguese are notoriously difficult for english speakers register.

It could be that Wernicke's area (were language is supposedly processed) is really just specialized for processing complex sounds that we are very familiar with. So you'd expect a bird-watcher specialization effect from ... opera goers? safe crackers? sonar operators?
Depends what your app is written in.

If I were doing this with a Rails app, I'd use Engine Yard for sure. Engine Yard Cloud makes stuff like load-balanced app servers and master/slave replication really easy (you can do it from the web interface), and they really know what they're doing and have tuned the stack based on that knowledge.

I don't know if there are similar offerings that are reasonably priced yet awesome for other languages though.

Ask HN: SSL Providers (UCC in specific)
For a project I'm working on we need multiple domains over SSL, however the server only has one IP(it's an ec2 instance). I've been looking around and it looks like UCC SSL certs might be the best solution. They allow multiple domains on the same domain, and are compatible with most browsers.

Has anyone used these before or have any experience? I've been looking around trying to see best price and such.

http://www.startssl.com/?app=39 has a good price but doesn't say if they charge to update the cert within the year(to add additional domains as necessary). Anyone work with them before?

Any suggestions of vendors or solutions?
I say that each person simply vote with cash and unbundle yourself from the system. As a consumer, use your power and control what you consume. So long as people just complain but still keep the system profitable by staying as customers, then we will get the economically efficient bundles that we dislike. You may miss a few shows, but you can catch them in a year or two. If you really love live sports, reconsider radio or even go see a game in person.
Nice work! Are these guys thinking about open sourcing the OT components? A couple of us are starting up an npm module to allow generic OT using node.

Yeah, I've coded for Word since Word 6.0 in the mid-90's, and it has always been my feeling that Microsoft doesn't want to make things programmable so much as they want you to think things are programmable. It's a feeling that's hard to verbalize exactly.
