Comment: Is this a Java problem? (Score 4, Informative) 411

by rubypossum (#49031637) Attached to: Your Java Code Is Mostly Fluff, New Research Finds
It seems like the Java ecosystem is fine tuned for producing a high signal to noise ratio as far as intent of code is concerned. So much of the ecosystem stresses templates, massive IDEs and other automated tools that make the production of thousands of lines of unnecessary boilerplate incredibly easy. Besides, isn't this the nature of Java anyway? It seems like it's designed to produce the most verbose code possible in the hope that if everything is explicit more bugs can be diagnosed since the compiler has more to work with. It's almost a troll article, seriously, it's like the guy is just tryiing to piss people off.

I think one of the most valuable abilities for a good programmer is to be a good listener. A big part of that is also being able to ask good questions. You need to be able to fully understand the problem to be able to develop the right solution -- remember, the solution that customer actually needs is not always the one they think they want. Also, being able to listen also means you will be better able to learn new skills.

Technically the continuously overwritten ring buffer seems hardly more difficult to implement.

One big problem would be battery life. There was a fatal police shooting recently which the police officers' cameras apparently did not record. One reason I heard was that they have 3-hour batteries which are supposed to last for a 12-hour shift. At the very least you have to keep a charger and spare battery in the patrol car to make continuous recording work. Better if you could actually make a single battery last the whole time and take away any plausible reason for not having a recording.

It sounds like the plan is for this ship to be the first of several, so the question is how much of that $20 billion investment is for upfront costs (design, shipyard upgrades, construction equipment) that will not be duplicated in subsequent ships. As it is, the first ship looks to probably at least break even or even make a decent profit (provided it works as expected) with bigger profits hopefully to follow. I am sure these numbers have been gone over very carefully. You don't make an investment this large on a whim.

Comment: Texas and Montana (Score 2) 525

I have driven that stretch in eastern Montana many times, and I have also driven that stretch of road in Texas. One thing the article doesn't mention about that toll road in Texas is that it was very expensive -- over $5 if I remember correctly. I tried it once not knowing the cost, and it was a lot of fun to drive on. But for that price, I can see why so few people use it, especially since you have to go out of your way. I was on my way from San Antonio to Dallas, so I didn't mind skipping Austin.

As for eastern Montana, the countryside is very open with gently rolling hills and long stretches of mostly straight sections of Interstate. Very often, you will not be able to see a vehicle in either direction (and just as often, no more than one or two buildings either), so the temptation to cruise is very high. Any wildlife can be seen from miles away, and there are very few trees. My only concern would be raising the speed limit on the western side of the state where there are more mountains and forests. There are some highways with 70 mph limits with limited visibility (both on the road and in the underbrush around) that makes for dangerous driving. As long as they take these things into account, it makes perfect sense. Montana already takes over a day's driving. just to get across.

Comment: Re:If the money is used to hire much better teache (Score 1) 143

You (The US) already spends the most on education per student then any other nation and yet have some of the worst test results.

That may be true, but it's not going to teachers!. (Link describes North Carolina, but I think the same is true elsewhere.)

I don't think "throwing money at it" will make it better. Sure, teachers will take home more money but the test results clearly show this doesnt improve the quality of education.

This study disagrees.

It's common knowledge that nvidia is having a hard time of things. They cancelled their server chip and their mobile devices are going nowhere. Discrete graphics cards aren't the market they used to be; and certainly not a growth industry. Maybe they're trying to get bought by Qualcomm or Samsung... there aren't many companies that are big enough to be able to absorb them and have it make any kind of sense. I wouldn't be surprised to see them sue Intel also.

Suing the companies that might be able to buy you out is not an uncommon way to start the negotiations.

Information Capacity Frequency Bandwidth * log2(1+signal-to-noise ratio) "In the lab" typically means "BNC cables" which give you very high signal-to-noise ratios. And in MIMO you can potentially treat each pair of antennas a separate channel. You use fancy techniques to increase the SNR for each channel. The nice thing about the 5GHz spectrum is that the frequency band is pretty large up there, and not as much interference with other unlicensed things (phones, microwaves, other wireless communication users... though as it gets more popular that will change) as the lower bands. The not-so-nice thing about the higher frequencies is that they tend to attenuate rapidly when the signal is going through something thicker than air.

Comment: Calling them on the rhetoric (Score 4, Informative) 166

My understanding is that ULA gets paid lots and lots of money to maintain two independent launch vehicles, the Atlas V and the Delta IV. That way if one of the rockets is grounded for some reason, space access is still available.

ULA prefers Atlas V because it is more profitable for them. But it uses engines from Russia.

The Russian engines are purchased from a company with ties to one of the people targeted by US sanctions against Russia... so the judge has granted the injunction to prevent purchasing those Russian engines.

ULA has a stockpile of some Russian engines already, and they have the (less profitable for them) Delta IV if they can't launch Atlas V for any reason... and running out of engines would be one of those reasons. But ULA would prefer to continue buying engines. But we've been paying them to have both rockets available, so they'd better be able to show up with what they've promised.

Separate from this injunction, SpaceX is asking for a review of the large block by of ULA cores, as it was done just before (a few days before) one of the final milestones of SpaceX being qualified to launch for the air force. I think it's not unreasonable for them to say that it's unacceptable to do a huge purchase when if you wait for a few days you would have multiple vendors competing for the bid.

So these cores with the arm V8 architecture add:
  • More registers (16->32)
  • DP SIMD
  • New instructions for crypto

and a handfull of other things. But all of the above aren't really benefits of 64 bitness, just the improvements to the architecture. The real benefit of a 64 bit architecture is the larger virtual address space... processes with >2-3 GB of memory. Every other improvement is usually just improvements that could have been added in 32-bit mode but they threw into 64 bit arch. Similar with x86-64.

Now come here and show us the stack of qualified, talented people for these open positions we have? Oh, wait, you're not actually trying to hire people? Maybe you mean there's no shortage of people writing crap on the Internet?

My total compensation as a qualified Engineer is similar to the average compensation for a doctor. I think that's reasonable. It's very hard to fill positions right now.
