That indicates that shipping separate executables for armv6 and armv7 alone would save over 10MB. Holy shit. (yes, latest iBooks still works on the iPhone 3G)

No, we have less than 4 pagefuls of apps on our (admittedly 16GB) 1st-gen iPad, and space is pretty tight. No music and we only keep around about 1-3 hours of video at a time. Games are by far the worst of course, but I'm sure part of that

I suspect the reason to be that the system has noticed that your apps haven't touched their memory for a long time and thus "don't need it". This is a reasonably valid assumption on servers: if you've got some daemons that are backgrounded

The long tenure (and prestige of the organisation) probably also contribute to the willingness of candidates to subject themselves to such a process. Getting someone who is currently employed to sacrifice multiple days of (paid or unpaid) h

I don't necessarily see a problem with that: it would avoid the messy cpu_to_le64 calls.

Why "every time you read the variable" then? You'd have a packed-binary-struct and a memory-representation-struct and conversions between them to use when reading or writing. I say "would", but I actually already do this. I have typedefs of

You shouldn't in general be using on-disk/network binary formats for your in-memory representation.

Nope. Even 24-bit RGB with no alpha is stored with a wasted byte in video memory these days. (outside of legacy video modes) The reason is alignment.

I don't know if it really would be that more work if you planned it from the start. Granted, I'm not very good or experienced at presentations and public speaking; so when I do I tend to spend a lot of time preparing. This preparation invar

You could probably do a lot worse to prepare for a talk than writing such a text+slides version of it, then distilling key words as notes from the prose and then practicing and giving the talk based on those.

This really ought to be the standard way to post presentations online. Unfortunately, it's more work than uploading to the awful slideshare .

It also entirely glosses over the fact that before the ISO-8859 standards, there were the horrendous code pages in DOS and numerous other encodings on other platforms, which made things hard even for Europeans, let alone languages with a no

There's nothing stopping you from leaving off the BOM as far as I know. The BOM is pointless in UTF-8 (the encoding is inherently endian-independent) and if you can guarantee by convention that your UTF-16 text will be read in the same byte

The cable tie is presumably so it doesn't shift when the cistern empties and refills when flushing.

It's not so much how offensive you are, but whom it's directed at and what the relative power balance is. Powerful or famous people will usually only attack or make fun of those who are more famous or powerful than them.

Good to know. I tend to upvote anything good I see anyway, so I've already been decluttering the unanswered section without realising.

The high-traffic tags are full of low-quality or frequently asked questions. The amount of duplication in e.g. the C++ tag is staggering, but there doesn't seem to be a conscious effort to enforce a no-duplicate policy of any kind. Picking

I'm not trying to put words in Paul Vixie's mouth by the way, so "explanation" is too strong a word. It's just my interpretation. I'd agree that the article could go into more detail on why this is a bad thing long term; I'm sure there's mo

The there's a certain fear of ISPs implementing work-arounds articulated in the article. I'm not surprised - the IP addresses in question can't ever be reliably reused if some ISPs set up special routes for them. And they will do exactly th

Considering the main use of hacked DNS is going to be stealing login info by redirecting to fraudulent versions of websites, I don't think these criminals will have a problem forging logos.

Yet another reason to try to solve this one out properly as quickly as possible. But I do find it worrying that e.g. http://dns-ok.de/ is a non-SSL site. Furthermore, it shows the German federal government's emblem and the T-Mobile and

Indeed, US tax forms are no fun; I've made that mistake before. It was a few hundred dollars' worth of work - I decided that trying to chase down the paperwork was not worth it in the end, as I made more money just spending that time doing

sure hope they patched that too! The patch appears to discard the DMA flags coming from user space, and instead applies the ones that are correct given the kernel's knowledge of the buffer. But yes, this is ultimately a kernel bug - speci

I think it's a requirement of PCIe for devices to support DMA to memory with 64-bit physical addresses.[1] In any case, the hardware clearly supports it in the case - the bug was that a 32-bit I/O vector was being passed off to the hardwa

Well, they have pushed the fix upstream and it's been merged into mainline. I assume you guys have people monitoring the subsystems for backportable bugfixes? I have no doubt that you guys have great support, but since the MegaCLI utility
