High School Student Builds Gun That Unlocks With Your Fingerprint

LostMyBeaver Re: Great one more fail (580 comments)

Hell... If you spend enough time at the range to actually ensure your skills are satisfactory enough to not be more dangerous than a gun that won't unlock, then maybe it wouldn't be a problem.

I personally also want laws passed requiring that guns used for self protection can't be activated without a corresponding video recording device.

Many of us have no issues with guns.... Only the people holding them. People with your personality are some of the scariest.

Microsoft To Buy Minecraft Maker Mojang For $2.5 Billion

LostMyBeaver Re: Ads (321 comments)

Or one could figure that Microsoft has a clear plan to capitalize and $2.5 was worth it to them. They will own a company that has done a better job the last few years on family games than Lego and Nintendo combined. Imagine if they had the resources of Microsoft.

Bash MS all you want, but XBox has been a pretty popular and successful gig. If anything, Sony was idiotic to let Microsoft beat them to this.

City of Turin To Switch From Windows To Linux and Save 6M Euros

LostMyBeaver Re:... and back again. (245 comments)

First of all... It's Italy. Turin is in one of the few sane parts of Italy, but in the end it is still Italy. I would suspect that the issue will be more like :
    1) Claim to leave Windows for Linux
    2) Use the law that passed in Italy a few days ago to guarantee refunds for the Windows Tax
    3) Buy machines with Linux on them instead
    4) Install pirated copies of Windows and Office on each machine.

Italy tends to operate more like an 3rd world country than a Western European country on most things. I've been there several times and will be there again soon in a few months. I think the only laws which actually stick are the traffic laws and those have items like "If the car has a license plate from somewhere else, it must no exceed the speed limit more than ...."

City of Turin To Switch From Windows To Linux and Save 6M Euros

LostMyBeaver Re:... and back again. (245 comments)

99% of Windows is exactly the same to the user for Windows 8 vs Windows XP. The only difference is, if you click the start button you get a screen of icons vs. a menu of icons.

After all this time, have you even tried Windows 8 or do you prefer to just comment on it without any prior knowledge?

Direct Sales OK Baked Into Nevada's $1.3 Billion Incentive Deal With Tesla

LostMyBeaver Wow!!! Nevada is screwed! (149 comments)

Laws should be made against building battery factories on American soil. Even more so, laws should be made against selling batteries unless that same company takes responsibility and completely recycles or reclaims all components of said batteries. Lithium is widely available from used cells, but it's cheaper to buy it new, so they just store it in barrels and produce waste.

How about this? When will Tesla research and deliver on an alternative to non-recyclable tires. Does Tesla have a policy stating they will only use technology which fucks our planet for millions if years?

Windows Tax Shot Down In Italy

LostMyBeaver And five people will be happy. (418 comments)

To get that $59 refund, people will spend 3.5 hours each and wait 6 months.

Oh... And most people won't bother. The court could have just paid the $300 which will actually get refunded from this instead of wasting what was probably tens of thousands or hundreds of thousands screwing with this.

Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

Get a small premade solution and skip the DIY thing. It's minimal power and unless you happen to like pain and suffering, a simple SSL VPN with a decent Web UI is much nicer than spend in half your life building one.

Microsoft Killing Off Windows Phone Brand Name In Favor of Just Windows

LostMyBeaver Re: Good decision? (352 comments)

Why not have all platforms on all devices and if I use a wireless thin client to dock a phone which is in my pocket and get a desktop. Add a wireless charger to the chair and I can leave the phone in my pocket. Add hands free speakerphone to the desktop or phone and messaging control to the task bar with caller ID notifications and I can use a Bluetooth hands free.

Make a wide variety of laptop style thin clients which can be docked with or without wires to the phone. Then you can mix and match. The device can last you 5 generations of phones.

There are many things which can be done like this. Intel processors for phones are more powerful than what I had in my laptop 4 years ago. Add enough RAM and enough storage and your phone can completely replace your laptop and desktop CPUs.

There are just an amazing number of options like this. Funny thing is, with technology of Linux like X and Wayland, if there was a desktop which didn't suck and apps which didn't suck for Linux, it could have done this years ago.

Tesla Plans To Power Its Gigafactory With Renewables Alone

LostMyBeaver Re: Most of it not tax financed, forced buy of (260 comments)

Hmmm... I saw the link afterwards... I would like to see a ruling that explicitly requires battery manufacturers to recycle their own batteries and most specifically the lithium. I don't care what it costs. It shouldn't be the duty of the tax payer to clean their mess and based on history, if you don't force it from the start, it'll never get taken care of when the problem is out of control.

Intel Launches Xeon E5 V3 Series Server CPUs With Up To 18 Cores

LostMyBeaver Re: What happened to the core-wars? (105 comments)

I think the changes in v3 probably are able to make the claim of more VMs per for due to memory bandwidth. Of course, then one could say 50% more cores at 20% greater capacity per core (my guess) which would be 65% more VMs per physical server.

I suppose Cisco will release a quad socket, 6TB RAM blade soon. I hope they'll loan me one to try. I was able to run entire companies with VDI on 3 60-core blade with V2, a little slowly, but effectively. 3 72-core V3 blades should be better.

The real problem comes that whether you're using Cisco with 640Gb/sec Ethernet or some aweful Infiniband on HP/Dell solution, I don't see how to get the data in and out of the blade quickly enough to use the cores. :( I wonder if the systems will even have enough PCIe bandwidth to support it.

I am hoping that with these servers, Cisco will support quad-SLI nVidia at some point. VDI is much better when it's 3D accelerated and adding massive numbers of GPU cores is helpful. But if they do, I doubt there will be enough PCIe lanes to handle storage and video.

So... New bottlenecks?

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

LostMyBeaver Re: We really need (524 comments)

You British guys keep bragging about your speeds to the Americans. I probably pay less and get over 60 up and down. I'm surprised you can acknowledge packets fast enough on those upload speeds to use your download speeds.

I am not even sure if civilized places like outside of America even use the term broadband anymore. It seems stupid since we don't have a narrow band anymore.

See, codecs allow things like full-HD at 6mb/s and 9mb/s at good quality. Home bandwidth should support at least on stream of Full-HD at -20db SnR. It should also allow some surfing and a phone call.

10Mb/sec isn't fast enough for that. 12-15Mb/sec is.

So, the American system is just broken.

GM To Introduce Hands-Free Driving In Cadillac Model

LostMyBeaver Re: Waiting for the second generation hands-free a (185 comments)

You're being rude.

This is awesome!!! I've been hoping for years that Cadillac would make a car like this. When the driver falls asleep or simply dies behind the wheel, it should get them home or to the morgue. It simply needs a heart rate detector.

The only downside is it will put the yellow pages out of business finally since Q-tips won't need one to see under the wheel.

Mozilla 1024-Bit Cert Deprecation Leaves 107,000 Sites Untrusted

Remember that the exponential math in DH and RSA is called a HARD problem, not and impossible one. Consider that regarding key strength 1024 bits of RSA is not very secure in today's world. I'm not saying it's cracked... Just weak.

Willow Garage Founder Scott Hassan Aims To Build a Startup Village

LostMyBeaver Incubators are worse (62 comments)

Incubators are generally a disaster since they're not actually meant to start businesses. They're designed specifically to take assist ventures in acquiring venture capital and then using a lock-in to the agreement to suck that money back out.

Incubators are a total disaster. The only advantage ever has been that they provide the coffee pot. You'll have to make your own coffee elsewhere.

Can ISO 29119 Software Testing "Standard" Really Be a Standard?

LostMyBeaver Automated test in is a minimum (152 comments)

First of all. I HATE WRITING UNIT TESTS!!! Know what I hate more? When I get bit in the ass because something that did work before stopped.

Unit testing is step one in any decent software development and I will never enter into or manage another project without unit tests being a critical component of the project. I'll just hire a QA guy to unit test all my code... I don't want to do it haha.

Second, there is absolutely nothing which can't be automatically tested too. When you write code, GUI, Web, Command Line, message based, etc... An automated script to test the code is critical. There are tools for it.

Everything should be tested automatically... That even includes memory leaks when exiting. I would never hire someone even for a C#, Java, Python or even PHP position who doesn't write code which cleans up properly after itself (even if that means correct use of the garbage collector).

I have worked on several multi-million line commercial applications, some with 500 million+ users. I have never seen a piece of code which could not be properly tested using the right tools. That can even include small embedded systems where we would have to actually implement a QEMU module or three.

So... Quit your bitching and write a test suite.

Research Shows RISC vs. CISC Doesn't Matter

LostMyBeaver Re: isn't x86 RISC by now? (161 comments)

You make a lot of good points. But any time you create a processor with cache miss prediction as well as branch prediction as well as execution parallelization, the instruction set has almost no effect at all.

You're suggesting that the instruction set interpretation is a separate unit to to out of order execution code. In reality, the first stage of any highly optimized modern CPU able to minimize pipeline misses must actually "recompile the code" (an oversimplification) in hardware before the actual execution unit and any intelligent designer would simplify the operations into much wider RISC style operations in the pipeline(s).

A purely in-order processor would certainly suffer from using a variable length instruction set.

What many people fail to realize is that ARM is very much a CISC ISA as well, but with a wider fixed sized word. So instead of increment ing instruction lengths by single byte units, ARM has two byte wide units in Thumb mode and four byte wife increments in ARM mode. Either way, it's nothing like MIPS (which is a dinosaur) which is a pure RISC architecture.

With the exception of a rare set of ULIW DSP cores (TI), it doesn't really matter. The major performance booster DSPs have is that code for a DSP are generally very small programs with extremely long pre-optimized pipelines which are not intended to be run in a task switching environment. Those processors don't need translation because they're completely pre-optimized. They also don't tend to have memory fragmentation and almost never have MMUs.

General purpose CPUs run code all ass-backwards because the code is unpredictable. The ISA will almost always benefit most from having as many possible version of instructions as possible for performance per watt.

The trick will be how to detect when specific units aren't needed and power them down when possible. Compilers and ISA will have no impact on this... Unless instructions are added to power on and off units explicitly based on the code entering the pipeline.

Intentionally disposable computing, a good thing?

LostMyBeaver (1226054) writes "I just read about Eric Schmidt's goal of moving everything to "the cloud" and making it so that in the future Chrome OS devices will be "disposable by design". To take a quick sucker punch on the guys at Eric, this sounds like he expects anything running Chrome OS to be garbage by design."

Environmental cost of battery recycling?

LostMyBeaver LostMyBeaver writes  |  about 6 years ago

LostMyBeaver (1226054) writes "I have been considering the purchase of an electric or hybrid vehicle for some time. The biggest problem I have currently is that both technologies make use of rechargable batteries. The same tree-huggers telling me gasoline is bad are telling me that batteries are bad too.

I'm only partially knowledgable in this area, but it appears the battery technologies are generally based at least on lithium ion, nickel metal hydride, lead acid and nickel-cadmium. I was hoping someone on Slashdot would be knowledgable enough to explain the environmental cost of recycling these batteries. If I understand correctly, after these chemicals are "spent" so the cells no longer maintain a charge, they are not useful for producing new batteries.

I can only imagine that the most common method of recycling the cells is to store the toxic chemicals of the batteries in barrels and refilling the cells with new chemicals. This sounds like an environmental distaster to me. Is there someone here that can help me sleep better at night by explaining what really happens?"
