Specifically, the talk mentions that the 6502 was pipelined and could do many instructions in 2 clock cycles, while the Z80 needed at least 4.

This translates to 2x the speed at the same clock rate.
iOS having a mission-critical bug is like a plane crash: a rare failure of a service we think of as working flawlessly every time, which we can do almost nothing to fix except hope the powers that be do it soon.

Android having a mission-critical bug is like a car crash: relatively unlikely for any given device, but there are so many devices running around that you'd be surprised if there weren't one happening somewhere all the time. And the collection of devices was never billed as just-working every time anyway.

(I have an Android phone and an iPad, and will be first in line for a Verizon iPhone.)

prorata shares of later rounds are important for two reasons 1) a vc's LPs want them to get and maintain a certain percentage of ownership and 2) down rounds are very painful from a dilution pov so the prorata really helps there

if you're only interested in absolute return, then dilution doesn't matter, only the value increase.

not that you asked, but as an angel myself i generally don't take my prorata - the startups that aren't doing that well, i don't want it, and the ones that are doing very well, i can't afford. also, the risk tradeoff (do i want to invest a marginal dollar in a new startup or to invest it in another startup? i want to intelligently maximize risk, i think.)
Speaking as a guy in medical devices, I would love for a YC-like organization to exist for my industry, though I think the structure of any such organization would be quite different than what PG & Co. do now.

Just three examples: First, the capital requirements of a med dev company are much higher than a software company. 11K + 3K*n wouldn't even cover the early biocompatibility and animal trials needed to demonstrate proof of concept.

Second, there is less measurable progress in 10 weeks relative to a software company, due in part to the length of the aforementioned trials.

Third, there's no ability to release a minimum viable product to customers and quickly pivot based on their feedback. That's partly because in medical technology 'customer' is an unclear concept and partly because your product won't get used in a meaningful way until feasibility human trials, which are at minimum several months after prototypes are created.
Very cool, it's hard to keep track of indentation levels though (like in the second example). Maybe add a way to fold subtrees of a conversation?

Guys will email the most attractive chicks first then work their way down the ladder (so to speak) ... if any of the chicks at the top of the ladder respond to them, thats where their attention is going to be until the figure out something is up or otherwise lose interest ...

With 50 impossibly (fake) hot chicks on the radar and only 30 real ones who probably fall below the 50 on the scale, that would give our boys more than enough time to seal the deal
Not quite. The bank's total reserves must equal at least 10% of their outstanding liabilities, which includes customer savings and checking accounts, in the same way that outstanding gift cards are considered liabilities for retailers. When a bank lends you money, they're really just signing a piece of paper that says, "we've given this person X dollars", thus it counts as a liability, in that somebody could come calling for that money.

When you deposit physical cash, the bank gains an asset, ie: that cash. It gains an equal liability, ie: the amount it credits your account. Thus the sum total of the amounts deposited and the amounts loaned must not exceed 10X the amount it either has in its safes, or that it has stored with the central bank.
Some of my friends verified the case. Highlights:

- PHP 5.3.3-1ubuntu9.1 i686 build (built on Oct 15 2010 14:17:04) hits the bug.

- PHP 5.3.3-1ubuntu9.1 x86_64 build (built on Oct 15 2010 14:00:18) doesn't have the bug.

In the i686 build ltrace shows the memcpy call repeating infinitely, suggesting the bug originates from 32-bit and 64-bit problems.
Well, he says it's ~100x faster than a GPU, and GPUs are ~100x faster than CPUs (in the applications for which they are suited), so the 10,000x figure is the speedup from CPUs.
The build time is different because you're running on different architectures with different packages.
I think if you redid the chart with the S&P 1000, it would be about the same. Choosing specific stocks is meaningless: given perfect knowledge about events, of course you can make a ton of money. For example, your retirement plan in 1990 could have been "buy a million shares of Apple". You would be exceedingly wealthy today. But your plan could have been "buy a million shares of Wang", in which case, you'd be a welfare recipient. The key to getting rich is to be able to predict the future perfectly.

This is difficult, so people average it out and choose something like the S&P 500. As this is a decent investment strategy, it's what the article shows.
I dislike google reader. I prefer native clients which cache the content I read. Currently, I use newsfire (mac) [1], before I was using newsbeuter (command line). Yes, I am aware that you can technically switch reader to an "offline mode". It just isn't the same as a native client with cached content.

Maybe the trend has been away from using google reader, and towards using native rss clients.

What he's doing is representing numbers with their logarithms, with limited precision. A floating-point multiplier/divider, then, turns into a fairly small adder, which is much smaller and faster. Square roots and squaring turn into bit shifting. They have some clever method for doing addition/subtraction efficiently. And since they can fit all this in a small area with short critical paths, they can clock it very, very fast, and include a lot of them on a chip.

As a practical matter, surfing from an https:// URL doesn't strictly strip referrers (in Google, DDG, or otherwise). SSL is intended to hide your data from the network, not the destination, so every browser I've tested will send referrers from https://SiteA.com/ to https://SiteB.com/ as long as both the referring and destination URLs are both https://
I used this article as a reference for the post:

http://www.crsr.net/Notes/Apache-HTTPS-virtual-host.html

It does cover the Apache config towards the end, and it doesn't look too involved. You can still follow the OP up until just before the "Chained certificates" section.

If you do need to use a chained certificate in Apache, you should see:

I hope that helps!
According to the presentation linked above, you've got to look carefully at each application, to see how it holds up when you decrease floating-point precision like this. But the list of applications where this would work is very impressive.
Agreed, but I could imagine one implication that might be revolutionary for urban areas. With driverless cars, it might easily become much more economical not to own a car at all. Even when one does own a car, they don't have to park it within short walking distance form their destination, as the car parks itself.
Free from strict parking requirements and regualtions cities can become much more friendly to pedestrians, and buildings (especially medium-high ones) may become cheaper and more free in their design.

I've tried using Square as a small business owner, and their model generally makes sense to me. We're not using them for our primary credit card processing needs, though. I think there are still some kinks that they need to work out.

The positive:

You can be up and running from zero to accepting a credit card within an hour. Compared to the traditional alternatives, this is incredible.

Their rates are reasonable. We do slightly better on the interchange-plus merchant account we use, but they aren't bad.

The mobile phone card reader is free, and works with both iPhone and Android.

The mixed:

Their customer service reputation isn't great. If you read their online forums, there a quite a few people that feel they aren't paid promptly. Seems like things are getting better though, and kudos to them for having an open forum!

They seem to have trouble getting the devices to people promptly. It seems like it might be worth a negotiating a packet rate with Fedex to get these there overnight, or at least to make sure they get in the mail immediately.

The negative:

The experience at least on Android isn't great. It feels like an app that was ported by an intern and then forgotten. There's a settings icon that takes you where the menu button should, and the back button doesn't actually work. For example, I started the app right now to refresh my memory, and I'm at the login page and can't figure out a way to get back to the first page without killing the app.

The GPS location trick is cute, but can't be turned off. If you are using the phone inside a store, it constantly searches for a GPS signal.

The reader (at least on Android) is flaky. It reads a card eventually, but seems to take 3-5 attempts. Worse, if you tap the reader in any way, it thinks you've tried to scan a card. This said, it seems like it's better on iPhone.

My advice to them: Raise more money, and spend it on improving the mobile applications and lowering the fees as much as possible. Low cost and simple is great marketing. Somehow get the reader into users' hands the next day after they sign up. And make sure it works.

Our current solution: We're using an interchange plus pricing model from http://vantagecard.com. They seem good so far. They resell for Global Payments, who are pretty awful to deal with directly. For our store, we use a wireless Verifone Vx610 --- works, but difficult to set up and expensive. For mobile, we use Inner Fence on Android (free) and iPhone (99 cents) and an Authorize.net Gateway ($10/month). Both are pretty good. We have a $50 iMag Reader for iPhone that works well to scan cards; on Android we have to punch in manually. Which really is to say that we'd love to be using Square if it was a little better implemented.

I think they have a decent chance of transforming the market if they can get their act together. Their ease of setup, and the fact that you only have deal with them and not 4-5 different entities, gives them a tremendous leg up. $200M? Yes, if they can pull it off.
It just depends on how the crash is triggered. Most things that users run into in normal usage don't have very much potential to become a serious attack vector for lots of reasons -- many programs are not particularly network-aware or may not provide any service an attacker is interested in denying, the attack may require local access (which is still serious in some cases, but obviously less than something that can be exploited over the network by sending a malformed query), and so on.

I think that the vast majority of stuff doesn't qualify as something that should be reported to a security team first. However, from a brief glance at the article, it appears that a remote user of a web application may be able to crash PHP entirely if he can find the right place to drop the number, denying access to all programs that depend on that PHP installation. That is a very serious bug and one incident can theoretically take out hundreds or thousands of sites and cost a lot of people a lot of money, not to mention time or frustration. Definitely seems like it should have hit the security group first to me.
I've been using keyword searches for longer than I've been using DDG but the thing is that instead of looking for a site to search on, you can just search for it on DDG and if there's a ! search for it you don't need to do the extra effort. It's essentially a precompiled search library with keywords that correspond to what you want to search for.
This would be beautiful for protein folding. That particular application is extremely parallel, numerically heavy, and should tolerate the loss of precision very well. It also eats up processing power like a black hole, so a few orders of magnitude speed improvement would definitely be nice.
Bug appearing at my Core 2 Duo / Win7 / PHP 5.3.0.

This is really serious. In fact, I’ve just tested if the problem happens for GET passed values and it does. Not all the passed data to a website is treated as a number, so not all websites with the PHP versions and configuration that could fail with this bug will be vulnerable, but definitely there is going to be a huge amount of websites that will do. This is really scaring.

I hope the PHP team patch it soon.

Meanwhile, a possible workaround would be adding this line at the very top of the execution of php website:

if (strpos(str_replace('.', '', serialize($GLOBALS)), '22250738585072011')!==false) die();

This will stop execution if any decimal version of the number were passed as parameter. Note that 222.50738585072011e-310 cause problems too, and any of the other possibilities to write it.

Do you know if there are any other possible ways to write the number that causes trouble too?

StaffCollege.Com - Like Facebook For Defense Personnel
To understand what this site is all about, you must be familiarized with the way in which military officers are trained in specific aspects of their profession. You see, they go to staff colleges in which they learn all there is to learn about these administrative, staff and policy aspects that an officer must have a firm understanding of. And what must also be mentioned is that it is usual for such training to take place more than once in the life of the same officer, at different levels in his professional career.

Well, this social network makes for finding the right staff colleges far more directly. All the colleges of such nature available in the US become instantly findable through this website, and users of StaffCollege.com are allowed to discuss the pluses and minuses each of these has got. In this way, better-informed career decisions can be made, not to mention that officers from all over the country have a better chance to begin forming true bonds of camaraderie.

This. Not every article from who-n-who's blog is going to be posted on HN, or hit the front page of Reddit, or be shared on Facebook. Somebody does actually have to subscribe to blogs they like and read it, somewhere. It can't be aggregation all the way down. RSS is probably too complicated for normal people (being named something as pointless and confusing as "Real Simple Syndication" doesn't help).

I can see how some people might be able to get by, but when I'm one of maybe 100 people subscribed to a blog, I'm not going to see it drift by on FB.

It is exactly the same. It just 'feels' different because your mental model doesn't connect the same dots.
These sums are paltry compared to the unprecedented quantities of wealth that have been transferred and continue to be transferred from the middle and lower classes to the elite of the finance and defense industries.

Aside from the wealth itself, there is a tremendous opportunity cost, since capital is moved from productive to outright destructive and criminal sectors of the economy.

The primary vehicle of these transfers is monetary expansion. All else being equal, a sound currency would bring orders of magnitude improvement in the real economy and dramatically increase standards of living for the bottom 90% of the population far beyond what can be achieved through programs like the ones you mention. Of course, there would be a deflationary collapse first, but this would be the best thing that could possibly happen for the vast majority of us.

For me the best the part of the post was

"We don’t adhere to any specific development process or methodology at BankSimple. We’ve borrowed bits from processes that we’ve worked with and enjoyed, and eschewed bits that we think are unnecessary. Our process is always evolving, and I’m trying to provide ample opportunity for feedback and change as we determine what works and what doesn’t."

Too many companies/startups set store by thinking whether their processes are agile or not. Or bring in external scrum masters to teach people how to do things and how to follow processes. But lot of people fail to understand that software development is people driven enterprise and its almost impossible to make 2 people work in uniform manner. And worse part if, lot of people think that, if you make 2 people work in same manner, chances of better software are increased multi-fold. Even though there has to be some basic processes outlining how to do things. It all comes down to DNA of the team and what the team is comfortable with when it comes to processes.

Is it really odd to measure relative to the actual natural base rate of inflation, which is negative in a healthy economy, instead of ignoring opportunity cost and arbitrarily assigning zero as the base rate? If an economy's natural rate of inflation would be -3%, but government monetary expansion keeps it at zero, are you just going to pretend there's no inflation?
