buf[4294967295] is perfectly valid and expected on platforms where size_t is 64 bits and int is 32 bits. buf[-1] is almost always a bug, and would be useful to default (with overrides) as such.

I think the opposite - signed types are a big problem in statically typed languages and the cause of countless bugs I've had to deal with (in other people's code) for most of my career. I think most languages would benefit from un

CPUs of this era were normally multi-cycle for every instruction, but I never expected in the Z-80 at least one cycle was because the ALU was only 4 bit. Love the detailed analysis - and this is just the tip of the iceberg of that site. One

Why is this "artificial"? Living in a big city and long commuting in/out is perfectly normal.

Just so the article is clear on which group it's trying to scapegoat: they fail to mention any of the big biotech companies who also run commuter coaches out of San Francisco. There are so many reasons for SF's growing wealth gap

Hz refers to the number of cycles per second. Everybody uses this as the effective transfer clock, but hey, everybody is wrong. It's correct to use MT/sec instead, but you're right that it's being pedantic and it's

This tallies with my experience in London. In fact, at Google, where after questioning their salary scaling vs competition, we were told that financial companies where NOT included in calculations. "WTF" or words to that effect were our gen

It would be sad if this were taken to be a failure of low prices vs discounts . There are plenty of other reasons why JCP is still failing. There's a lot of inertia to its existing reputation and customer base, for starters. I think the

A bidding system would inevitably favor businesses with more resources to spend on employment. I'm not sure whether that would end up being a good thing. It's already extremely expensive to hire someone on an H1B visa, despite what myths

Wired is selectively quoting and interpreting. Linus is talking in generalities and unfortunately that means he's missing the specific, immediate problem that a lot of people are going to face. Secure Boot in itself isn't necessarily a prob

But the point still stands that this specific exploit is NOT a JVM exploit? Is it an actual exploit of the JVM implementation, or just the libraries? The problem has always been that Sun shipped way too big a runtime for Java applets - the

by pslam 14y ago
Is it actually a JVM exploit, though? From FireEye's blog it sounds more like a library exploit which allows unconstrained clearing of memory, which then leads to a JVM escape because it blows away the JVM state. I wouldn't class that as a

This is the clearest presentation I have ever seen about digital audio in general, even if it's not trying to be that general. It really is peculiar how many otherwise technically minded people with experience in DSP and/or audio somehow th

Almost no hardware audio decoders use DSPs, or at least actually need to, since about a decade or more now. The manufacturers you mention use DSPs for bad reasons - usually the inertia of software already using a coprocessor and not being w

Why do people write while(1) instead of for(;;)? Are you saying that "while(1)" is superior in some way? Why? I prefer "for(;;)" because it is explicitly defined as an infinite loop, but "while(1)" needs an implicit cast of "1" to "true", a

"Not in-game footage". Just like the Google tablet mock-up video vs reality. Anyone can craft a mock-up video. Not everyone can execute on it, and in recent years Google isn't doing well on that score.

The most interesting bit for me is the estimate for total capacity, which is ~10^19 bits. That's about 2^63 bits, 2^60 8-bit bytes, 1 exabyte, or (probably) the sum of all Google data centers, in one brain.
