Is the Tesla Model 3 Actually Going To Cost $50,000?

beelsebob Re:Who to believe? (330 comments)

Given that he explicitly said he wasn't going to build the hyper loop... It seems to be working out pretty much exactly as he said.

SanDisk Releases 512GB SD Card

beelsebob Re: 1024-fold (210 comments)

Last I checked the prime factors of 125829120 were 2, 3 and 5, and it very much was not a power of two because of that ;).

SanDisk Releases 512GB SD Card

beelsebob Re:1024-fold (210 comments)

No, the JEDEC standard actually agrees with the IEC one - it states that for memory you can optionally use the SI prefixes with binary calculations, but that for storage you should use base 10 computations with the SI prefixes.

SanDisk Releases 512GB SD Card

beelsebob Re:1024-fold (210 comments)

Yes, because your OS incorrectly computes the number of GB. It computes the number of GiB, and then displays GB.

Notably, if you stick that same terabyte drive in a mac, or many linux boxes, it'll register as 1TB.

Why are you talking about memory at all in an article about permanent storage?

SanDisk Releases 512GB SD Card

beelsebob Re:1024-fold (210 comments)

That was pretty silly of you, given that data isn't stored in powers of two. When was the last time you saw a hard disk with an exact power of two capacity?

SanDisk Releases 512GB SD Card

beelsebob Re:1024-fold (210 comments)

No, a "traditional" GB is the one that was defined way before computer scientists got their hands on it –1000. The 1024 "definition" is actually simply a bug. Engineers working on early machines had a choice – take a bug that pretty much no one would notice on an early machine (because files over 1kB were very rare, much less ones over 1MB), or take a massive perf hit. It takes a long time to compute the size of 20 files when a division by 1000 takes 300 odd cycles on a 10kHz machine. It doesn't take such a long time when a right shift 10 takes 1 cycle.

Bottom line, early engineers decided a known bug was better than the enormous perf hit of getting it correct. That doesn't mean that what they did is now correct. It means it remains a bug in some OSes.

No, that would be MibiBytes and GibiBytes. A GB is 1000 times larger than a MB.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

beelsebob Re:Seriously? (524 comments)

On the contrary, 4Mb/s is almost certainly not enough (by the time you take into account contention etc) to stream video. Something like netflix will not work over that, and frankly, I expect any definition of broadband to include the ability to use a video streaming service.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

beelsebob Re:Numeric equality in PHP (729 comments)

There's no particular reason to not have comparable values of different types

Sure there is - they have different types, therefore they're not equal. It's a ridiculous, useless operation, because it doesn't actually do anything more than always return false.

That said, there's good reason to have an "isSimilarTo" function, but that's not at all the same thing as equality.

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

beelsebob Re:Anthropometrics (813 comments)

No, ultimately, their job is to carry passengers. That means they need to offer enough space for a passenger to sit in. The airline's only choice is to not shrink the seats any more. This may of course mean price increases for all seats.

IT Job Hiring Slumps

beelsebob Re:bringing in more H1Bs will solve this problem (250 comments)

Actually, compiler theory is a great example of a language you can't easily learn in any language. The small lightweight structures it generates, and the referentially transparent transformations that you run those structures through lend it strongly to being done with functional languages, and if not, very close to the metal languages like C. Heavy weight OO languages tend to end up just causing you to write 3 tons of boiler plate, rather than actually learning the theory.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

beelsebob Re:Numeric equality in PHP (729 comments)

You shouldn't. You should (in all languages), explicitly convert the type, and then compare things of equal type. For bonus points, you should only use languages that enforce that the arguments to == are of equal type.

What you just wrote is a strong indicator that you have no clue how much undefined behavior you have in your programs, and just happen to be getting away with just now.

Twitpic Shutting Down Over Trademark Dispute

beelsebob Re:Wait, what? (81 comments)

Of course it makes sense. They can either cut their losses now, and leave with their profits. Or they can be sued into oblivion by Twitter, and let them, and the lawyers walk off with their profits.

Does Learning To Code Outweigh a Degree In Computer Science?

beelsebob Re:Probably not. (546 comments)

I wouldn't say that learning to code necessarily outweighs a degree. But I do think university courses are too heavily focused on theory, and not enough practical application.

The job of a university is to teach theory. These are not vocational collages, they are universities. The practice is meant to be something you are more than capable of teaching yourself if you're any good at the subject.

Low-Carb Diet Trumps Low-Fat Diet In Major New Study

beelsebob Re:The diet is unimportant... (588 comments)

No, exercise is not it. I mean, it does burn calories. But it's far harder to get thin by exercising more than it is to do so by eating less.

For example, even a relatively fit person will walk at 4-5mph at most. At that speed, they'll do about 10,000 steps in an hour. That's one hour to burn a whole 400 calories. If they run, they might make that half an hour, but that assumes that their cardiovascular system is up to running for half an hour straight, which lets face it. No fat person's is.

Alternatively, they can make the same dent in their net calories for the day by simply not eating one chocolate bar.

Exercise is great for you - but it's great for getting fit. Not great for getting thin.

Low-Carb Diet Trumps Low-Fat Diet In Major New Study

beelsebob Re:What they don't tell you (588 comments)

That's kinda the point. No, humans don't need carbs. We did not evolve eating carbs, and we don't really gain anything very much by eating them (other than a craving for more of them).

If I still had mod points, you'd get a +1. Intel motherboards are great. They're nothing fancy pants, but everything that's on them is solid and well supported.

Apple Switches (Mostly) to OpenStreetMap

beelsebob beelsebob writes  |  more than 2 years ago

beelsebob (529313) writes "In the recent release of iPhoto for iOS it appears that Apple have started using OpenStreetMap's data. Unfortunately, there are still some problems. Apple are currently not applying the necessary attribution to OSM; they are using an old (from April 2010) dump of the data; and they are not using the data in the USA. Fingers crossed apple works through these issues quickly!

Apple are now one of a growing list (including geocaching, and foursquare) to Switch2OSM."

Apple drops iPhone Developer NDA

beelsebob beelsebob writes  |  more than 5 years ago

beelsebob (529313) writes "Today Apple dropped the iPhone developer NDA.

We put the NDA in place because the iPhone OS includes many Apple inventions and innovations that we would like to protect, so that others don't steal our work. It has happened before. While we have filed for hundreds of patents on iPhone technology, the NDA added yet another level of protection. We put it in place as one more way to help protect the iPhone from being ripped off by others.

However, the NDA has created too much of a burden on developers, authors and others interested in helping further the iPhone's success, so we are dropping it for released software. Developers will receive a new agreement without an NDA covering released software within a week or so. Please note that unreleased software and features will remain under NDA until they are released."

Squirrelfish takes a bite out of performance

beelsebob beelsebob writes  |  more than 5 years ago

beelsebob (529313) writes "We all recently heard that Google Chrome had introduced a new Javascript engine called V8, that made all the other engines out there look like toys. Today the WebKit team announced that their Squirrelfish engine has been optimized a lot more, to produce Squirrelfish Extreme. The improvements are enough that WebKit now runs Javascript faster than Chrome. The competition between browser makers seems to be paying off for us consumers with some major improvements in performance now."

beelsebob (529313) writes "Very well known is the iBook G3 logic board failure issue, however, less well known is that iBook G4s have been failing with the same symptoms almost as regularly. The G4 variant of the laptop is not covered by Apple's logic board repair program, thus if it dies, it's dead. Or so we thought, until recently. An enterprising guy has posted a fix for the problem that works simply by sticking a tiny bit of plastic under a chip."
