The One App You Need On Your Resume If You Want a Job At Google

umafuckit Re:MatLab is not really a good programming languag (205 comments)

The presence or absence of semi-colons is not really an important factor in choosing a language. Yes, there's shitty MATLAB code out there by self-taught people. But if those people were self-taught in Python, then they'd be producing shitty Pyhton code instead. You can't judge a language by the code quality of its inexperienced users. You can write crap in anything.

I've work with both MATLAB and Python and I see MATLAB has having various advantages. It has excellent syntax for matrix manipulations--much nicer than numpy. It has huge collection of highly optmised functions that generally work very quickly. I do a lot of image processing and when I ported my MATLAB code to Python it generally ran much slower. I spent ages on Googling and talking to people in forums. I couldn't get it to run faster. In MATLAB it just worked quickly with no extra effort on my part.

With MATLAB you get a huge collection of algorithms at your fingertips. They're generally very well tested and the syntax is consistent throughout. The documentation is excellent, too. Python, on the other hand, is a network of libraries which often have rather different syntax to each other. It's common for version updates to lead to regressions.

The One App You Need On Your Resume If You Want a Job At Google

umafuckit Re:Shash-job-vertisement (205 comments)

R has great syntax for a stats package. For a programming language it's an awful mess. I always find myself having to look stuff up, because every library does things differently.

umafuckit Re:Shash-job-vertisement (205 comments)

I had the opposite experience, unfortunately. I found it much easier to write fast linear algebra stuff in MATLAB than in Python.

Flight Attendants Want Stricter Gadget Rules Reinstated

umafuckit Re:That's not the reason you're being ignored. (405 comments)

People don't listen to that preflight announcement stuff because they've heard it a hundred times before. People who've flown even a couple of times before don't need to listen.

That may not be true, actually. I've got a skydiving licence and I can tell you that the beginner training depends absolutely on mindless repetition. All you have to do on your first two or three jumps is arch your back and pull the cord at 5,000 feet. There are two people there with you. It really only takes about ten or twenty minutes to understand what's required and practice it a few times. However, that's not going to cut it. When you're in a very high stress situation you no longer think normally and instead enter a semi-conscious autopilot mode where you react instinctively. I had no idea what happened during my first few jumps, for instance, virtually no recollection. The only reason I did what I was meant to do was because I'd practised it many, many, times (for two days) that it just happened without me thinking.

Based on my skydiving experience, I often wonder how much people really take in when they watch the in-flight safety stuff. I wonder how effective it is to merely watch what your supposed to do as opposed to practising it. Of course the latter is impractical so we're stuck with the former.

Wind Power Is Cheaper Than Coal, Leaked Report Shows

umafuckit Re:Too bad... (610 comments)

Whilst I agree with you in principle, "half a billion years" is not a unit of mass and most plants and trees that have existed didn't turn into coal. I'm not being pedantic, the way your post is written emotively implies that a substantial proportion of all the plant biomass that has existed was locked up as coal. This isn't true. The fossil fuel carbon pool is only about twice the size of the terrestrial biosphere, which re-circulates comparatively quickly. Thus, the carbon from most ancient plants got recirculated and didn't get locked up as coal. In fact, both fossil fuel and biosphere carbon pools are dwarfed in size by the carbon pool present in limestone (so fossilised marine organisms), there's also a vast store in the oceans. Look up the carbon cycle on the Wikipedia.

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

umafuckit Come back when it's peer reviewed (986 comments)

Some PDF of a website isn't really good enough. When it's peer reviewed by a major journal and repeated, then I might be interested. Until then I don't believe a word.

The CDC Is Carefully Controlling How Scared You Are About Ebola

umafuckit Re:Ebola threat (478 comments)

Then, correct procedures weren't followed.

You could say that about most car crashes too. People don't set out to have accidents, particularly nurses who know the risks of the disease they're working with. Accidents happen, though. If they can happen so easily, then it may be hubris to say that Ebola can easily be contained if it spreads to the West. It may be harder than we think.

DId you hear about the nurse in Spain who got infected? An infected glove brushed her face. It doesn't take outlandish behavior (like corpse water drinking) for this disease to spread.

Ask Slashdot: Is It Worth Being Grandfathered On Verizon's Unlimited Data Plan?

umafuckit Re:Boost mobile (209 comments)

Your definition is 100% marketing lies. You didn't read the thread. The thread was about T-Mobile's 5 GB plan. Which was always referred to as such both in the thread and at point of sale. So there are no marketing lies. Only that fact that, from many user's perspective, the plan is unlimited. Of course, if you want to go out and pay more for an unlimited plan then use less than 5 gigs, that's up to you.

Ask Slashdot: Is It Worth Being Grandfathered On Verizon's Unlimited Data Plan?

umafuckit Re:Boost mobile (209 comments)

If your maximum realistic usage is x and the limit is, say, 2x or 3x, then it's unlimited as far as you're concerned. That was my experience with T-Mobile. I used the plan whenever I wanted an never went remotely near the limit

"LOL" it's effectively unlimited unless you insist on watching Netflix movies on it. I used to have the T-Mobile $35 plan. I used the network with abandon and never remotely approached the limit.

Breakthrough In LED Construction Increases Efficiency By 57 Percent

umafuckit Re:Woo hoo!! (182 comments)

Unfortunately it is not only likely that LEDs are worse but the problem is already playing itself out. I've seen it. In my area I've noticed and increase in white light light pollution over the last five years. The IDA, which is a body involved in attempting to reduce light pollution, is concerned. There are multiple reasons why LEDs are becoming problematic.

Light scatters off the ground too and back into the sky. If the fixture is bright enough then any gains from it being more directional are lost by the scattered reflection off the ground. The directionality for LED street lights is better, but it's only a matter of time until they're used for building up-lighting, and some of the current street-light fittings do still leak light.

The other big problem is the LEDs being white, in particular many of them are a cold blueish white. Night vision is particularly sensitive to those wavelengths, so for a given flux the impact of a white LED is substantially worse than the pressure sodium lights they are replacing. In addition, because they're broad-band emitters, the effectiveness of narrow-band light pollution filters for visual astronomy is reduced. Don't forget also that LEDs are able to emit more light for less power. All of these issues create a brighter ambient light dome that spreads over large areas. If you live right next to an LED street-light and have it shining anywhere near your yard then it can be "like daylight", according to amateur astronomers I know. So that completely obliterates backyard astronomy in a way that sodium lights never did.

You're right the potential benefit is that they're dimmable. But the question is how much they're dimmed and when they're dimmed. Given their increased potency as a light pollution source, I don't see us ending up in a situation where light pollution levels go down. In the West, levels of light pollution have increased far faster than the population over the last 30 years. There is no indication that LEDs, with their cheap light, are going to reverse or slow this trend.

Breakthrough In LED Construction Increases Efficiency By 57 Percent

umafuckit Re:Woo hoo!! (182 comments)

You'll see that sucker from space.

Indeed you will. With the spread of super bright white LED street lights, the light pollution situation will get exponentially worse. Amateur astronomy has been on rocky ground for some time. These lights are the death knell. Real pity.

Debian Switching Back To GNOME As the Default Desktop

umafuckit Re:How many of you are still using Gnome? (403 comments)

Can you tell me what is an "unproductive pattern"? I ask because I find I am at my most unproductive when I procrastinate, which could involve web browsing, or making pointless and trivial tweaks to my desktop or OS set up. I find that I'm good so long as I can have multiple desktops arranged in a grid, key combinations to move between desktops, text editor of my choice, and ideally a BASH terminal. So the main desktop environment I find problematic is Windows, and this is mainly because I've not found a good virtual desktop program. On Linux I can get on equally well with XFCE, Mate, or KDE.

DuckDuckGo Now Blocked In China

umafuckit Is Google blocked in China? (82 comments)

Last time I was in mainland China (about 2 years ago) I was able to use google.hk -- it wasn't blocked outright. However, it did appear to be throttled in some way. So searches took ages and it was a pain in the ass. One my Chinese friends said the she always used google.hk, even though it was slow, because she preferred the search results. So at least at the time, it was usable in practice. Also, I heard that the more tech savvy people in China know how to bypass the firewall. I don't know the details so can't verify, but apparently it's quite common knowledge.

Dremel Releases 3D Printer

Well, it's a CNC extruder rather than a CNC miller. TBH, I think most of the fuss about 3D printers is just that they're called "printers."
