An excerpt from Google history:

Some Rough Statistics (from August 29th, 1996)

BackRub is written in Java and Python and runs on several Sun Ultras and Intel Pentiums running Linux. The primary database is kept on an Sun Ultra II with 28GB of disk. Scott Hassan and Alan Steremberg have provided a great deal of very talented implementation help. Sergey Brin has also been very involved and deserves many thanks.

There's something to be said about rapid prototyping and evaluation.

JL2010··on Keccak wins the SHA-3 competition
I find it interesting that the contributors work for semiconductor companies. I would've thought that something like this would be more likely to emerge from a team with a mathematics/CS/academic background more so than hardware. Perhaps these algorithms can (and will) be going strait into some new hardware cryptography IP cores?

1400x1050 14.1" !

JL2010··on Lenovo Computers, Soon To Be Made In America
I personally have moved on to widescreen (16:10 1680x1050 being my favorite) due to the ability to split the screen in a editor|browser or editor|pdf configuration (or two-pane editing).

This plus their tried-and-true keyboards. I'm not sure if I like where the new keyboards are headed, I never thought I'd see the day where a T-series would have a chiclet keyboard!

Real keyboard + 16:10 hi-res, high quality display and real thinkpad (IBM era) build quality and I would be willing to pay north of $1500

JL2010··on Indeed, An Almost Entirely Bootstrapped Job Search Giant, Gets A Monster Exit
Having used Indeed during tough times I am happy for their success. It's a great search engine and without it I'm certain that my job-searching productivity would not have been as high as it was back when I was looking - which is crucial when trying to pump out as many (good quality) applications as you can to increase your chances of an interview.

I love their product and it's still the first site I visit when I'm curious about what's available in different areas. Congrats to the team!

JL2010··on SpaceX wins $440M contract with NASA to develop Space Shuttle successor
>There's a ton of risk just in getting out of the house and driving on the road. But there's risk in sitting on your ask at home too.

The risk factor involved in manned space missions versus a trip to the grocery store has got to be huge orders of magnitude in difference. This is an unfair, and frankly, useless comparison.

>if our choice was to explore the Solar System with a vehicle no safer than the Soyuz or to stay at home the choice has to be to explore, every time.

This is where I can't agree. You have to define "explore" - i.e. the particular objective of that flight on a case by case basis - and ask if it really warrants sending a human being up to do that job. Yes? Then by all means. Do it. No? Then find a safer alternative that accomplishes the same goal and that sheds the challenges of keeping a human being alive in a truly hostile and unforgiving environment. Also, I wouldn't consider sending an autonomous vehicle out to explore as "staying at home".

I get the emotional appeal... I just don't think it's rational for every case unless we really need a human's capabilities in space.

JL2010··on SpaceX wins $440M contract with NASA to develop Space Shuttle successor
Perhaps I should've re-worded my previous comment because I did not mean to suggest that we abandon manned missions forever or that we try to experience space vicariously through robots.

I'll elaborate. There is tremendous risk involved in sending people to space, I'm sure those who sign up for it understand and accept that, but it's a tragedy when it goes wrong given the caliber of people who end up dying. The overhead in designing for human needs (oxygen, water, food, waste facilities, etc) seems like a waste of time and engineering effort until we can better guarantee their safety. Of course I think the time will come when it becomes as safe and accessible as a trip on a 747, but I think an effort in purely autonomous systems that parallels the efforts being done on manned space technology should be considered to serve as a supplemental aid to further space research - a lot of which, I'm sure, would end up contributing to that dream of reaching the stars.

JL2010··on SpaceX wins $440M contract with NASA to develop Space Shuttle successor
Is manned flight necessary anymore?

I feel that a lot of design overhead is put into making a shuttle or space station safe and livable for humans. Why not focus on the main mission: to conduct research experiments.

I know there is the romantic idea of human space travel, but if it's not ready yet, why not invest more in autonomous systems and more advanced robotics for the sake of conducting the actual mission and sparing the lives of some truly brilliant and extraordinary people (potential astronauts).

JL2010··on OnLive comes to Ouya, Controller Makes Full Frontal Debut
Honest question: is anyone here using onlive? How is the gaming experience? Are the visuals, performance and latency acceptable? How are they doing in terms of their sales/subscribers?

I remember reading about it a long time ago thinking that it would be a sign of the future and something I would definitely want to try. It seems to have fallen off of my radar and I don't know anyone who uses their service, and I would consider myself and my friends "hardcore" gamers.

JL2010··on Google Fiber Plans & Pricing
Did anyone else catch the "2 year contract" bullet point? Despite that, of all the Telcos out there, I suppose I would be more willing to sign one with Google than any of them.
JL2010··on The Apple (Used) Premium?
And for this reason I wrote myself a script to wget the Macbook pro 15" refurb page, and parse it for: Price, manufacture year, and matte screen option. If it matched my criteria 3/3, then it would email me.

One morning I got that email and I no longer had an excuse :D

JL2010··on Ouya Breaks Kickstarter Records
Is it mentioned anywhere that the actual planned pricing (after the product releases) will be $99? The "$99 Android console!" headlines are great for publicity, but I wouldn't be surprised if the actual product (if it ever goes on sale) might be in the neighborhood of $250-$300 while the pledgers are the only ones that will actually get a $99 console "sold" as a loss for the sake of generating interest.
JL2010··on Backdoor found in a China-made US military chip
"Unlike SRAM-based FPGAs or conventional ASIC solutions, ProASIC3/E devices offer one of the highest levels of design security in the industry. In fact, ProASIC3/E devices bring new levels of security to the FPGA market place. An FPGA industry first, secure ISP is performed using the industry-standard 128- bit AES block cipher algorithm. Reprogramming can be securely performed in-system to support future design iterations and field upgrades with peace of mind that valuable IP cannot be compromised or copied." ISP stands for in-system-programming
JL2010··on Backdoor found in a China-made US military chip
I'm going to put my speculation hat on here. Others here have mentioned that the chip in question is an Actel FPGA.

First, we must understand what these are used in: embedded systems. Typically, at the heart of most embedded systems you have two possibilities: a microcontroller or microprocessor, or an FPGA. The microcomputers run some kind of firmware (instruction set fed to a processor architecture) which is completely different then an FPGA which are actually re-configurable transistor arrays to implement fixed digital logic. This transistor configuration is typically loaded from EEPROM on power up - so it is stored/uploaded by a user somewhere after they've done some work in their CAD tool.

In either case, whether it be firmware written for a microprocessor based system, or the "firmware" for an FPGA (I forget what that logic routing configuration format is called - technically not firmware since it's not instructions) it is likely that whoever wrote it would want to protect it from being read or protect their device from having another firmware loaded on. There are many schemes to do so, it is possible that this is what has been compromised.

JL2010··on F-35 Joint Strike Fighter Coding Standard Documentation
Just to add to what was already said, the doc said for enumerator values - which are indeed lower case in the example. Not a blanket statement for all variables.
JL2010··on Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years
A reasonable model if you assumed that cats exclusively ate rats - and wouldn't wreak havoc on any other native rodent populations (if they still exist).
JL2010··on Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years
So long as there's something there to eat cats. Introducing one invasive species to cure another can lead to unpredictable ordeals.
JL2010··on Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years
Also: Australia's efforts against the cane toad, invasive fish species all over the world introduced by humans for "sport", Florida's efforts against the Burmese python (which has become the dominant predator - even swallowing local adult alligators).

Some other interesting things to note:

1. Made by some ex-Ableton folks. 2. A multi-user collaborative mode over LAN or internet

JL2010··on Ask HN: Where do HN people hangout online?
Various stack-exchange sites. I'm more of a hardware type so the Electrical Engineering stack-exchange is the one I frequent most.
JL2010··on Louis CK's self distributed special up to 1MM revenue in 12 days
This doesn't help much, but an excerpt from his previous news update when the special hit $500K:

"Minus some money for PayPal charges etc, I have a profit around $200,000 (after taxes $75.58). This is less than I would have been paid by a large company to simply perform the show and let them sell it to you, but they would have charged you about $20 for the video."

So somewhere north of $200K.
