It doesn't –but measuring 100 grammes of cherry tomatoes makes things a lot easier ;).

David Cameron Says Brits Should Be Taught Imperial Measures

beelsebob Re:You must be an engineer (799 comments)

That is so not true that I think you are trolling. If not you must be an engineer because you are worrying about levels of precision that simply rarely matter.

As mentioned above, 1 "cup" of flour can vary by 30%, simply from the humidity of the air, and the compactness of the flour. Add to that a ~10% variation simply from exactly how level your cup is, and you're at around a 40% variation in how much flour you're putting in a recipe. That's enough to go from a bread that's fucked up because the dough is liquid all the way through to a bread that's fucked up from the flour not incorporating properly.

Almost all baking requires precision, almost all deserts require precision, and many main courses require at least more precision than "you can be 50% out with the quantities".

David Cameron Says Brits Should Be Taught Imperial Measures

beelsebob Re:Volume versus weight in cooking (799 comments)

Metric is no more accurate than US customary units.

No, the issue is that the use of it is much more accurate, as expressed above, the americans have a deer love of using the wrong units even within their own system.

  They use volume units for compressible things
  They use volume units for undeformable things
  They use volume units for things with large air gaps between them and inconsistent shapes
They use the same words for volume and mass units (oz in the US can interchangeably mean ounces or fluid ounces for example)

In general, trying to follow a US recipe that needs some level of accuracy is basically impossible. If you're trying to bake bread, you'd better have a metric recipe, or you're screwed.

David Cameron Says Brits Should Be Taught Imperial Measures

beelsebob Re:Idiot (799 comments)

The reason is, 125ml and 250ml have no practical relationship, while "1 cup" and "1/2 cup" do. So when a recipe calls for 1 cup of anything, you can measure that quickly. If it's half a cup, then you use half a cup, or if you have it calling for 1.5 cups, you use the 1/2cup 3 times.

Actually, cooking is the one place that US imperial measurement drives me up the fucking wall. 1 cup of something trivially measured by volume isn't so bad, though 100ml is just as easy to measure. The big issue is when you get to "1 cup of flour" or "1 cup of butter" - things that are much more easily measured by mass, or things like "1 cup of cherry tomatoes" where the amount you get will vary based on the size and density of the particular tomatoes you have today.

Basically, no, the kitchen is exactly the place I want metric measurement - it is if anything the best example around a house of where you need accurate scientific style measurement.

Exxon and Russian Operation Discovers Oil Field Larger Than the Gulf of Mexico

We do now know why the Russians and Americans are starting to posture over Eastern Europe though... They know there's the potential for a war, and are positioning themselves for it.

Rosetta Code Study Weighs In On the Programming Language Debate

beelsebob Re:Who cares about succinctness .... (165 comments)

The problem is that OOP languages rarely have more readable code. Instead, they typically have simply code with more boiler plate.

SanDisk Releases 512GB SD Card

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.

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.

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

beelsebob Re:Seriously? (533 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 (819 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.

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  |  about 6 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  |  about 6 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."
