Ask Slashdot: Where Can I Find Good Replacement Batteries?

caseih Re:I prefer eBay myself. They have the most select (92 comments)

Interesting. Usually when I buy from Ebay the results are mediocre at best and the seller demands that I give him a full star review. I don't have the ebay foo or the patience that you have. I've bought cell batteries from a ebay seller that looked very much like what you recommend, and they were junk. I also bought from a random, supposedly reputable dealer on Amazon, and they were junk (brand name, two year old batteries). Went to a local store specializing in batteries and they were junk too (also two year old, brand name, batteries). The problem with a lot of vendors is that batteries have a shelf life. If the new batter is more than a year old, it's not going to perform.

I'm trying Anker now and will see what happens.

33 Months In Prison For Recording a Movie In a Theater

caseih Re:The real crime here (396 comments)

Until the DMCA, copyright was always a civil offence, as it should be, with the penalties to be monetary in nature, not prison. Remember all the FBI warnings on old VHS tapes about going to prison for copying the video (or heaven forbid public performance)? They were all bold-faced lies. At least until the DMCA criminalized copyright violation. Now you can get more jail time for copyright violation than for violent crime such as rape.

FarmBot: an Open Source Automated Farming Machine

caseih Re:Nice Summary (133 comments)

Close... there are still things that require human intervention currently, though in the future combines will be completely autonomous. Right now humans have to watch for interruptions in crop flow, obstacles, etc. Just got in from harvesting wheat all day. GPS did all the steering, the computer took care of cutting height across uneven ground. Though my combine does not have it, many combines can moderate their ground speed as well, changing speed as crop conditions change to make sure the machine is running at 100% capacity.

John Deere, and soon Case, have technology for linking the grain cart with the combine so the combine operator (or the computer in the future) can control the position of the cart to load it evenly while unloading the combine's on-board grain, all while moving through the field.

Pretty much all our machines have GPS steering now. With machines that are too wide to drive accurately without overlap. Everything from planters to cultivators, sprayers, harvesters, etc.

Given the expensive obstacles in my field (oil wells, pivot irrigation systems, other machines, trucks, etc), I do prefer to oversee things currently but I wouldn't say farmers are not wanting this sort of automation.

Ask Slashdot: Should You Invest In Documentation, Or UX?

caseih UX? Meh. I have enough experiences in life (198 comments)

All this talk in recent years about UX as in "experience" drives me up the wall. Talk about euphemism! Why can't we go back to calling it what it is: user interface?

Floridian (and Southern) Governmental Regulations Are Unfriendly To Solar Power

caseih The real problem is hooking back to grid also (306 comments)

I'm sure if she wanted to she could go off grid and run everything on solar power and no one could say anything. The trouble starts when she wants to connect her house to the utility power grid, and use it essentially as a big battery, and then have the utility company pay her when the meter runs backwards. It's that process that the power companies and government regulations make difficult, and you can understand a little bit why. From their point of view she wants to have her cake and eat it too.

And where I live, it's the corrupt monopoly transmission line company that charge more for the connection itself than the actual power delivered. It make so much money (guaranteed 9.5% ROI a year by tax payers!) in fact that Warren Buffet is set to buy them out.

Between the regulation and the line charges, it's not economical to invest in solar or wind on a small scale around where I live either.

Google Offers a Million Bucks For a Better Inverter

caseih Re:so... (260 comments)

I've had good luck with the Honda suitcase inverters. They aren't particularly clean emissions-wise, but they are quiet, fuel-efficient, and produce the cleanest power of any inverter I've tried.

William Binney: NSA Records and Stores 80% of All US Audio Calls

caseih Re:Uh (or cost) (278 comments)

Umm, no it is in fact entitlement spending. By a long ways. The black budgets may be black, but they still have to be accounted for and you can actually find out the total of the black budget allocations, just not what they are going for.

Study: Global Warming Solvable If Fossil Fuel Subsidies Given To Clean Energy

caseih Re:Wait until those lamers find out... (385 comments)

You're being pedantic of course, but for all intents and purposes, batteries aren't the real source of the power we use every day. Gas, coal, or nuclear generating stations are. Batteries get charged up with that power, then take it to where it's needed and release it. You said it yourself, energy cannot be created nor destroyed. All the batteries in the world aren't going to stop global warming if electricity is coming from Coal. Some battery chemistries form batteries that have a full charge when manufactured, and some of these are not rechargeable. Therefore we'd have to class these in the same category as other non-renewable energy sources. Which doesn't help the problem of finding renewable, clean energy production sources.

New Single Board Computer Lets You Swap Out the CPU and Memory

caseih Re:Just think of what you can do with this! (122 comments)

Very much this. While a few people are doing cool things with robotics, remote sensing, or UAVs with these small SBCs, most sit and gather dust.

Those actually putting their SBCs to use are by far in the minority. I have plans for my Pi to do some remote sensing work, but so far they are stalled. So it's in a drawer until I find time.

My drawer is full of these devices including Pis, GuruPlugs, and SheevaPlugs. Theoretically useful, but never quite panned out. Could make nice file servers, but honestly a hackable NAS box that also runs linux is probably a better buy. If I need a web server facing the internet, I'm better off hosting it somewhere. If I need a local web development server, a virtual machine or my existing desktop machine fits the bill much better. Tried to use a Pi for XBMC, but it would crash during video playback every 20 minutes or so. Not very encouraging.

I'm also tired of messing with the various and sundry ARM boot loaders, since ARM is such an non-standardized platform.

New Russian Law To Forbid Storing Russians' Data Outside the Country

caseih So they don't have to ask the NSA (206 comments)

I wonder how such a thing is going to be enforced. Seems to me this is more about burdening Russian companies who use western services than it is about securing the privacy of Russian citizens. Besides if Putin forces all Russian companies to keep their data local then his cronies can more easily do their own spying on it, rather than have to beg the NSA to give them access, which given Russia's frosty relationship with the US, is probably pretty much cut off these days.

That Toy Is Now a Drone

caseih Re:Not surprised, mixed feelings (268 comments)

Wow, that was unbelievably irresponsible of Ars Technica. I think you're correct in your assessment. It is pretty much all of us.

Even laying aside the FAA, I believe that it wouldn't be too hard to get widespread public support for pretty strict regulations of these devices. And I wouldn't be too opposed to some regulations either.

That Toy Is Now a Drone

caseih Not surprised, mixed feelings (268 comments)

As an RC airplane enthusiast, who likes to dabble in FPV and UAVs, I must say that I'm not surprised. However my feelings are a mix of outrage at the FAA as well as understanding. When a few irresponsible people use their toys in ways that are, well irresponsible, I'm not at all surprised to see the FAA come down hard on everyone. I think in many ways this is a tragedy of the commons. A few idiots have actually ruined it for everyone. When a toy has the power to kill people, or to hurt them, and people do stupid things with them, then it ceases to be a toy. We are now seeing stories in the news almost weekly of stupid people flying their toys in reckless and dangerous ways.

That said, I don't see how the FAA's rules are enforceable, nor do I see how the FAA can actually claim to have the authority to make rules in an an area that, as far as I can tell, congress has never granted them the power to do.

If FAA truly has the power to regulate a hobby, then they need to have a framework in place to allow this activity to continue safely. It's happening everywhere in the world. Banning it in the US will only put companies behind the curve who want to develop and use the technology.

NASA's Orion Spaceship Passes Parachute Test

caseih Re:SpaceX Will Beat NASA at this Game (75 comments)

Yes I agree. I'm also happy that NASA is making progress on this. I think it's a worthwhile endeavor, even if it is tied to earmarks and corporate welfare, much moreso than SpaceX's lucrative NASA contracts.

I also am excited at what SpaceX is doing. They are certainly the farthest along, and most likely to succeed in the near term. Who knows. Maybe in the future if SpaceX is the only American company visiting the space station and hauling astronauts, they could just take over space station operations and open it up to civilian scientists. That'd be cool. If dangerous and impractical.

I suffer from jet lag ...

caseih Re:East - Sleep, West - Awake (163 comments)

For me what matters is rest, period. IE sleep. At any time during the flight in any direction, and as much of it as I can get. Traveling is very tiring anyway. If I get exhausted, say by staying awake coming west as you suggest, I just start feeling crappy and my sleep schedule will take far longer to adjust. Instead I just take a benadryl and sleep while I can. That means I wear a mask and earplugs and try to get 6 hours sleep or so coming west in the daylight. I'll be tired regardless, but less tired this way. That night (in whatever timezone I'm in), I try to sleep as close to my normal bedtime as possible, but earlier is okay. I'll take another benadryl if necessary. But then if I wake up in the night, it's important to not get up and do things. I just lay in bed, and I will fall asleep again. I'll soon be on a fairly normal schedule. The only lingering aspect of jet lag for me is that I do tire more earlier in the day, often going to bed by 8 or 9. But mornings and afternoons don't feel much different for me. That lasts about 5 days or so. If I can work things out so that my first night in country I can sleep for 10 hours or so, I have zero jet lag. One time I managed to stay awake until 7:30 pm, then crashed and slept until 9 am the next morning (did wake up at 3, but didn't get up). Felt wonderful and my schedule was fully adjusted.

Flying lie-flat business class also helps greatly!

Workaholism In America Is Hurting the Economy

caseih Change is as good as a rest (710 comments)

I think the problem is that the nature of most of our jobs and work environments are repetitive, non-physical, dull, uninspiring, and often lacking in meaningful interpersonal communication. You can only take so many hours of that sort of stuff without burning out. In that context I understand and agree with the supposition that our productivity is hurting because of these long hours.

On the other hand, sometimes working long hours isn't that bad of a thing, but it depends on the context. Currently I'm working in a family partnership doing agribusiness (IE farming). Depending on the day I may be working from 8 to 14 hours a day. But since it's a lifestyle as well as a job, and family lives here on farm, it's not quite as soul-sucking as working 14 hours behind a computer screen, though sometimes I do spend hours doing things on the computer doing things like server maintenance, or the odd bit of software development, which is rather tiring after a few straight hours (maybe it's being behind a screen shining in one's eyes that makes jobs so fatiguing). Each day differs pretty significantly. Yesterday I put in some hours after supper and came in at 9:30 pm. Today I was done by 5. Those seasons that demand long hours do get old in a hurry, but they don't last forever, and there are other compensations. Also I take one full day a week off (Sunday). Most farmers really enjoy the lifestyle, and their families too, as well as many farm workers, despite sometimes putting in long hours, and they do find balance and it works out. At least for some people.

So it's not just a simple hours put in issue, but more of an inability to balance personal and family needs against an employer's demands, and the type of work these long hours consist of.

Researchers Unveil Experimental 36-Core Chip

caseih Re:Moore's Law (143 comments)

And hopefully in any lectures on Moore's Law, the students learn that Moore's Law refers to transistors on a die, not the speed of the chips. This 36-core chip probably jumps ahead of Moore's Law a bit, as it's got to be a fairly large die. In any event Moore's Law continues to hold, more or less. Other things like CPU speed have followed a similar trend in times past, but no longer do now.

Russia Wants To Replace US Computer Chips With Local Processors

caseih Re:Logical continuation for applications and OSs (340 comments)

Replace Windows with ReactOS? That's funny. Putin might have taken a passing interest in ReactOS for obvious reasons, but I'm highly dubious that anyone has replaced Windows with ReactOS for any reason, especially in the military. From what I can see ReactOS development crawls along at about the same rate it always has, with no sign that Russian money has caused any dramatic leaps in stability or usability.

Freecode Freezeup

caseih Move to sourceforge? (62 comments)

How will visiting sourceforge help me see summaries of new software releases? Guess I'm confused. I always thought freshmeat.net (renaming and moving it to freecode.com was stupid IMO) was just a listing site, and that's what I've used it for the last 14 years. And it's still been useful at that. Takes money to pay the bills, but it seems to me that this is another example of Dice thinking they can takes something that's popular and monetize it without bothering to find out why it's popular, and what value it gave to the community.

Red Hat Enterprise Linux 7 Released

caseih Re:... and with systemd. (231 comments)

Have you ever written an init script? As an admin you should have written one or two in your day. You'll know how fragile init scripts are, reinventing the wheel over and over again to do basic things like prevent a service from running twice. Want to restart a service automatically when it crashes? Well you hack another script that runs in a cron that uses hackish ways of determining if the daemon has crashed: Check for a running process, find out if it's responding, kill it if necessary, start it again. Gets unsupportable in a hurry on production systems. So we resort to third party solutions like supervisord, which work pretty well, but aren't integrated into the init system at all, so they don't obey runlevels. The two largest unix vendors have not shipped sysv init for many years. Solaris replaced it with SMF, and Apple with LaunchDaemon. systemd is superior to both systems.

As an admin surely you can see the benefit to creating simple daemon definition files that can get your daemon up and running (with restart, with protection against multiple instances) all with two or three lines of a simple text config file.

From what I can see systemd is modular, and if you don't want to use journald, you don't have to. On RHEL7 it's set to small, ram-based log for crash reporting only, with the real enterprise-required logging going to rsyslog which is a conventional logging facility.

I personally cannot find fault with Pottering's work. It just works for me (I am an admin also). I also am extremely grateful for pulseaudio also. It just works now, and lets me do things that no other system currently does, like record one program's output to mp3 while listening to music or watching videos. Can't argue with results.

Damaged US passport chip strands travelers

caseih caseih writes  |  more than 2 years ago

caseih writes "Damaging the embedded chip in your passport is now grounds for denying you the ability to travel in at least one airport in the US. Though the airport can slide the passport through the little number reader as easily as they can wave it in front of an RFID reader, they chose to deny a young child access to the flight, in essence denying the who family. The child had accidentally sat on his passport, creasing the cover, and the passport appeared worn. The claim has been made that breaking the chip in the passport shows that you disrespect the privilege of owning a passport, and that the airport was justified in denying this child from using the passport."

Media doublepeak in reporting BPI raid

caseih caseih writes  |  more than 7 years ago

caseih writes "The BBC reports that "The British Phonographic Industry (BPI) is investigating allegations of an extensive illegal music filesharing ring at a Honeywell plant in Scotland." What's amazing is that the article treats this entire incident as if the BPI is somehow the equivalent of Scotland Yard or even the MI-5. Not only does the article report this as being the equivalent of real crime with hyperbole, invoking the inevideble comparison to fraug, human-smugging, or even pedophilia rings, but it also has some real gems like a quote from a so-called expert saying, "Filesharing music in the workplace is illegal, misuses company resources, wastes employees' time and introduces network security risks." Regardless of one's stance on the problems of copyright infringement, this kind of bad reporting really shows how the copyright cartels have gone too far."
