Because I don't want to look at 243.82cm on my tape measure, or if I am trying to lay something out to match the 16 in on center studs 40.64 cm, 81.82, 121.92, 162.56, 203.2, and then 243.82 cm.

For new stuff you could probably cheat and just base it on 40cm, which would be fine and perfectly acceptable, but for the old stuff which is still out there over the 8 feet, I'm already off by more than an inch which is enough to not hit the stud. Most framing isn't great, but still the error is additive and fractions are hard enough to work with that I'd want to avoid it.

I think the transition for lots of things really has an additional cost. Is that speed limit sign metric or imperial? Sometimes its obvious, other times not, and there are thousands and thousands of different governments responsible for them.
Not surprising though that they thought this.

When I worked computer sales in retail in 1995, I would frequently have people come up and ask me during a sale or some such nonsense: "What would I use this thing for?" Usually it went a little like this:

* Do you write letters or papers?

* Kids who write papers?

* Interested in looking on the internet? No?

* Have a college kid who is on the internet? (do you know what email is?) No?

* Play games? (fairly rare) No?

* Keep track of finances? Don't want to do that?

At this point I just kind of shrugged my shoulders. Outside of some attempts to explain that computers were something good to learn about (in particular for kids), it was a pretty hard sell.

Probably over 50% of the time they asked that question - "What is this thing good for?", I knew where we would end up.

I challenge you all to make two changes today with regard to this. First, switch your phone to give you the weather in Celsius. It gets super simple fast:

0 and below - Freezing. Wear a warm jacket and closed toe shoes or boots.

1 - 10 - Cold. Wear an overcoat (a light one if you are used to colder weather)

10-15 - Early spring time. Long sleeves are probably in order, maybe even a sweater.

15-20 - Late spring. Wear short sleeves.

20+ - Warm to hot. Wear short sleeves. If it gets to be 24+ shorts are appropriate.

I am deliberately not giving conversions to Fahrenheit here because I think that's how you just go back to using it. Try to internalize the metric system here.

The second challenge is to switch your clocks/watches to the 24 hour mode. Not strictly metric system related, but you will not have to worry about AM vs PM again.

For the advanced users: switch your car to show your speed in km/h instead of m/h.

For the super-advanced users: try to figure out how many liters per 100 km does your car consume :).

Edit: if you cook (and you really should), use a scale set to grams instead of measuring cups for any recipes you are making. Almost all foods list both oz's and grams on them. You will get much more accurate measurements this way and will learn to gauge what 150 grams of cheese looks like, etc.
I would estimate 75% of Web developers are "clueless" about algorithms and data structures (although that's a fairly strong word).
We're by far the largest country (in terms of population) to attempt a conversion. That counts for something.
In engineering, linearity refers to having two properties:
a) f(x+y) = f(x) + f(y) where x, y, are two values, and f is a linear transform/function
b) af(x) = f(ax) where a is constant
In this case, the transform is the conversion between C and F. Since there is +/32 in there depending on direction, neither of these properties hold.

For example, yards to meters is a linear transform. 3 yards converted to meters + 2 yards converted to meters = 5 yards converted to meters. This is not true of temperature. Adding 32F to 32F gives 64F, which is not the same as adding 0C to 0C.
A0 is a square meter, and everything in the A series has an aspect ratio of sqrt(2) and different sizes are achieved by simply folding (or cutting) in half. It's actually pretty neat... check out:

I don't care if the slides are full of words as long as the presenter doesn't just read word from word. The art of public speaking is more important than slides. I pay attention to slides but I also pay attention to speakers.

____P is a broadcast specification, and was never meant to become a display measurement. It intentionally only defined the vertical resolution as this was the only specific resolution requirement; for example 1440x1080 is a valid 1080P broadcast resolution (it would still be displayed in 16:9 however). Moreover specifying Progressive is utterly redundant in modern displays (and thankfully is becoming universally redundant).

____P is no less of a marketing label than 4K, just a different one. Any monitor should be defined by its resolution; however this is clunky as hell- as demonstrated by the sheer mass of people keen to inappropriately use the ____P nomenclature.

UHD seems a valid shorthand of this resolution; and to be fair it tends to get used; although often alongside 4K.

I still prefer using JSR-305 annotations/tools (like Findbugs) to do static analysis. Reification should help Optional<?> become more useful, but why would you ask for run-time checking when in most cases compile-time checking identifies the problems?
Uber CEO: Self-Driving Cars Are the Future, Drivers Are Not
I wrote a quick shell one liner that aggregates text files and simple templates into resulting html files.

find ./txt/ -type f -name '*.txt' -print0 | xargs -0 -I£ sh -c 'newname=$(basename £ .txt).html; cat templates/header.html £ templates/footer.html > html/$newname'

Each new page (html file) is a sandwich. The filling could be transformed markdown rather than plain text. A little find and replace for titles, and such like would make for quite an easy static site generator.

I even found a bash markdown transformer:

In geometry, this would be an affine transformation.

Emiland has, in fairness, greatly improved the text. "77% less financing volume" is a far better annotation than "77% below". Meeker would be better advised to improve her writing skills. Her design skills are just fine.

Wow you must not have read my comment at all. I explicitly said we should convert, but that there are some considerations that need to be made. I even said that now is a better time than ever.

Considering that the Fibonacci sequence is exponential, and hence the Nth Fibonacci number contains O(n) digits (well, in any sane base at least), you cannot compute the Nth Fibonacci number in under O(n) time.
The biggest improvements are to typography, color palette and using a single background across headline and body.

This idea is cool, except for the gesture. There needs to be a way to summon a block with one finger so that one-handed use is still possible.

I'm assuming that the drive to stay as close to the current experience as possible influenced that - there's currently no "free" one-finger gesture/action on the home screen. I don't know how to pull it off, but needing to use two hands seems like it kills off the notion of doing things quickly.

edit: Although it's worth pointing out that while it's a cool party trick, it's not something I'd use day-to-day. Changing the Control Centre to let me keep applets open within it for things like 1Password or composing a message? That would get used every day.
Hi! I'm one of the four (that I know of) independent ISPs that serve Milwaukee and the surrounding areas with a combination of WISP, Fiber, and Copper technologies. We all suck at advertising and rely on referrals.

In the Milwaukee market we all focus on business users (and generally ones that need symmetric or high-upload service and would be looking at a fiber build) or MDU applications because... For the past several years we've seen a consumer preference for absolute lowest cost over quality or available bandwidth. At the extreme end we still have users on wholesaled ILEC DSL on provisioned for 768k download that just don't care enough to upgrade or switch because they like the sub $20 price. It's ILEC controlled so I can't just upgrade them out of the goodness of my heart either.

The participants list for our little Internet Exchange is somewhat workable as a directory of area independent ISPs although some of us are datacenter operators or as far away as Racine or Madison: http://www.mkeix.net/
How is that useful? To glance at that information you have to:

1. Unlock your phone

2. Press home to go to the homescreen

3. Swipe to the screen that contains the widget

4. Possibly scroll the widget itself

Android itself has several better alternatives for such glanceable information that are quicker to access:

- Google Now / other search plugin

- Lock screen widgets / lock screen "now playing" info

- Lock screen app quick links (available using Play Store lock screens or some vendor software)

- Persistent notifications in the notification bar

- The recent apps menu (to actually go to the app you want!)

Don't get me wrong, I love Android. I've used it for the last 5 years. It's just that I've never understood why people use widgets. They're too clunky to be useful even for the most basic of things.

I guess that's the beauty of Android, you can use the phone whichever way you think is best. This particular feature is not something that Apple should be envious of however. It really isn't universally popular or considered useful on Android. Windows Phone's live tiles are much better, but wouldn't work on Apple home screens either, because you would still have to fiddle about swiping through your home screens.
Snail22 isn't complaining that the result's not perfect. It's that it's not even moving the right direction. The new "design" is strictly worse than the original.
I don't think you have to do kernel work to warn people they should be cautious when submitting to mainline. As a matter of fact, I've read the book you mentioned, alongside some others such as Understanding the Linux Kernel by Bovet and Cesati, and I've brushed against low-level kernel features such as memory-mapped I/O or epoll, so I'm at least aware of what might go wrong if you decide to write a kernel module just for fun and then issue a pull request against the original source tree.

I don't think contribution should to be discouraged, but I do think that people who have no sense of responsibility should be kept away from the kernel source. Kernel development is not supposed to be for everyone, it's hard. Great expertise and technical mastery is needed to write good, quality and responsible code that is suitable for inclusion into a kernel that today powers so many different devices.

I will admit, again, that my warning was probably too harsh, but I still stand firmly by the viewpoint that "casual" or careless kernel contribution should be a no-no. It's one thing to poke around on your dev system to find out how stuff works, but entirely another to write an official patch to a system that millions of people around the world rely on.

EDIT: And when I say that "kernel development is hard", I mean that it's harder in the general case than writing most userspace code. It requires you to think of stuff you don't usually worry about (think of the all the race conditions that might occur) and let go of all the abstractions provided to you by the kernel, it's harder to debug than userspace programs, and you have to support a wide variety of hardware platforms, each with its own quirks. In fact, I haven't done any kernel development just because I was intimidated by how hard it is. I've tried writing a kernel from scratch (OSDev wiki was a great help) but it soon came to be a buggy and unmaintainable set of kludges that was barely doing any real work.

These articles are always missing the subtly of the issue. I'm going to ignore MPH signs & mile markers, because they really don't matter much for international interoperability. The important things are focused around dimensions on parts, packaging, engineering drawings, etc.

Sure, we all know that lots of areas in the US already use the metric system. I have personally used metric in the biomedical & consumer electronic industries, but had to use imperial in the defense industry. Generally the more advanced or international the industry the more metric it is. (That's why construction may simply never switch).

What people generally don't realize is that other countries are still using the imperial system because the US drives the market. Lots of imperial system parts are made in Mexico, China, etc to feed into US supply chains. Complete wild ass guess, but I bet more imperial system bolts are made in China than in the US.

It's not like there is a ban on making non-metric parts in the 'metric countries'. They'll do it, and often times non-metric parts are cheaper even coming from metric countries because of the volumes.

It really seems like an industry by industry fight, and by and large it is a ratchet turning in only one direction. Even the defense industry is started to use metric for some parts. I think 50 years from now it will be a moot point.

I have yet to see one of these Bootstrap-centric editors that is worth a monthly fee. Bootstrap is so well laid out and so well documented that I can't see many instances where this would that much of a time saver or worth the premium. Presumably a shop that is churning out basic site after basic site may benefit from the ease of use but I can't imagine that is a big market.

The articles doesn't give examples of why you need to test your logo in black and as small size. I think some logo designers only focus on digital so here some non digital examples:

Small logo examples:

How is that an iOS's "performance problem"? Use Safari. It's not like iOS doesn't offer the best scrolling experience compared to Android/Chrome.

We're a big Java user but apparently faster - our current environment is JavaSE 7 and JavaEE 6. We'll move to JavaEE 7 when there is commercial support for an application server (probably JBoss EAP 7.0.0) and will likely allow Java SE8 at the same time.

We're quite a bit slower at migrating existing applications (except for security issues), but because we code defensively, we are generally backwards compatible.

Having worked in construction, I think it is the last point you make that is most important. Though a 2x4 is 1.5x3.5, it is a standard dimension. In the US, construction standards (lumber sizes, door frame sizes, ceiling heights, etc) are all in feet and inches. Changing them creates a compatibility nightmare. That said, I don't know of other industries that suffer the same challenge (perhaps others can think of them). Bicycles for examples transitioned reasonably quickly from English standards (e.g. 1 in. stems and 27 in. wheels) to fully metric for road bikes at least.
> * Tooling that exists in standard units seems to be a bit of a red herring: I dislike having to own wrenches in both standard and metric units - a transition to one set would actually be nice. At a larger scale, i.e. manufacturing, it would make sense to start replacing things with metric on regular maintenance cycles. With very long cycle things just having a label change.

I don't think you'll get rid of that second set of sockets/wrenches for decades. There are going to be just too many instances where there is an old connector, nut, bolt, etc. that needs to be worked with. I think of it as having two sets of wrenches or am buying two sets of wrenches anyway. The metric and imperial sockets come in one set and share the ratchets.
The e's in the Heineken logo are rotated a little to represent a 'smile'. Not a lot of people will see this but the logo gets a 'softer' feeling because of it so people will somehow notice it.

I don't normally pick on the design of sites submitted, but people in glass houses...

As soon as I scroll down a little the header changes and the entire first paragraph disappears behind it. It's very jarring and it's actually making it difficult to read. I'm sure it seemed like a cool idea, but design has to play second fiddle to functionality: It doesn't matter how fancy the design is if the product cannot perform its function.

A similar poor choice between shiny visuals and functionality has torpedo'd their redesign of the slides. They aren't the prettiest but I can very easily read the original charts. The new design massively reduces the contrast between text and background and makes the axis labels much smaller and a lighter font weight to boot. The result is very difficult to read.
It is interesting on things like this plays out. If the executive bought it and it tanked, the exec would be blamed for make such a bad decision. However, if the acquisition became 100x, the exec would be hailed as a visionary and a hero.
As a European myself the request of the citizen for the removal of the content was legitimate you can't have past problems looming over you your entire life and certain things are just too personal and shouldn't be so easy to find to begin with.

I don't want a potential google search to reveal I got my home repossessed for instance.

The employer could take advantage of this by offering you a lower wage since you're desperate it's more likely you will take it or not hire you at all.

However the way the court choose to handle this was completely wrong. This shouldn't be handled at search engine level but at the publishing website level.

The ability of anybody requesting content to be removed from the internet should be very limited in the types of things they can have removed and rigorously monitored by a court of law.

Plus there should be a private database containing the Names of the people who had content removed and what was removed.

That would discourage political reasons since the log of their activity exists even if the content doesn't.
To reveal the text? I'm not sure how workable that is, as the tap and hold is for movement and would show text below your finger anyway.

Study: Device Specific Faults (Android)
Britain, including Scotland, is Metric. The fact that metrication happened in the 60s means people of a certain age describe the weather in both F or C, depending on the situation.
The UK is certainly unique in the EU for its exceptions which include the use of miles per hour for speeds, miles for distances and, for example, 'pints' for beer. But much EU legislation on the sale of goods has been enshrined in UK law and means that most items have to be sold in metric units of weight/volume etc.
