Re:A battery has replaced Hawaii's last coal plant on Friday January 12, 2024 @12:37PM (#38971194)
To me this is an example of extravagant and inefficient use of money. Instead, it should have been used to find a huge pool cavity somewhere high on one of the Hawaiian mountain or enlarge one. And then pump up the water to the pool when the electricity is cheap, and release/generate electricity when it is in demand. Stupid and robust implementation that just works and certainly less expensive than $219M.

I’m surprised that list doesn’t include a movie UFO. https://m.imdb.com/title/tt6290798/

Even though the plot is rather simplistic, it has a few interesting physical concepts embedded in a clever way.

That's pretty cool - reminds me about an experiment of improving small fridge efficiency by adding insulation on the sides of the fridge. In the end it worked out favourably for energy efficiency angle.

I'd be grateful if folks point out more improvements/builds that target off-grid home/office setups.

Great points...believe it or not it happens, but privately, in a case by case manner. Also why do you think companies and founders are in the business of making employees wealthy?! What is the specific reason for all of these being implemented?
Where exactly I “leave lies”? That’s a serious allegation and is thrown very casually here, as if it is self-obvious.

What he says and what will actually happen is two different things, especially in politics. If you have actually examined the URL I’ve posted, you might (maybe?) realize that money isn’t exactly the problem in the SF municipal budget. Maybe it is something else, like ehm.. actual governance?

And where exactly these taxes will go? From pockets of CEOs to pockets of ... municipal bureaucrats, whose median salary floats at a humble mark of 175K/year?

Look, believe it or not, I am in the same boat - never had issues with paypal, but neither I'm a heavy user. Randomness and the severity of paypal actions is a huge issue for me.

The subject of the discussion is paypal's surprise wedding with crypto. As stated in the above comment, my argument is: from customer perspective it is a bad, crazy proposition.

Hey, paypal has a loooong history of random, inexplicable deplatforming of customers, and mixing that corporate attribute with crypto makes sense only on executive powerpoint slides.

This is a hilariously uninformed statement. Which cryptocurrency?

I'd even argue that the juggernaut BTC was _designed_ to be trackable, and as the recent history shows, law enforcement successfully and multiple times did exactly that when needed - tracked, identified and penalized bad actors.

I've got the invite to paypal's beta program for crypto. Honestly, you've got to be mad to be dealing with paypal. I've read anecdotes from people, losing access to their accounts, locked up money in paypal, etc... It all seemed to be just stories, seemed rare, circumstances unclear. Until one day this summer, out of the blue, paypal demanded ID of my spouse (for her account), and then after reviewing it, "permanently limited" the account, gloriously exclaiming:" Aha, we got your information, now you won't be able to use your current account nor open a new one!"

Trying to get to the customer support is yet another saga, and I will spare your time, but the net result is nil. Nobody in the support knows why the ban happened (there was no real reason to ban a paypal customer with over 8+ years, buying some random stuff on ebay), nobody can revert it, nobody really cares and there are no appeals.

Receiving a note from paypal today regarding crypto looked like a bad, really dumb joke to me and an insult for my spouse. You gotta be completely clueless or insane to trust this shitty company with your crypto. One of the key points for crypto is the lack of "deplatforming", which the sinister paypal does left and right, at the same time not even being able to explain its actions, nor comprehend consequences.

Paypal - never!

Could you cite an example where ECC requirement on GPU was real and demonstrated to be needed? In practice, I don't know anyone who'd willfully take 10-15% perf hit on GPUs, because of a cosmic ray.

The thermal design for "datacenter" card can be better for sure. And on-board memory size and design. That's about it. For how many x over geforce price tag is that?

It is very known thing. Whatever reasons were to create Glassdoor, but now in practice, it became an instrument of misdirection and is used to _deliberately_ and _intentionally_ mislead people.

The case for Mars by Robert Zubrin, Arthur Clarke - highly recommended for technically minded folks. One of my favorites of 2018.

You might want to try COWON mp3 players -- they have the directory structure for tracks and a very good sound quality. I never looked back and everyone how tried COWON do not look at iPods either anymore.

Have you tried to employ Graphics Processing Units (GPUs) to do the computation-intensive tasks?

I could imagine that using CUDA-enabled kernels might be of help for processing images.

What about integrating Adobe PDF? Does Adobe Reader still requires dances around to show something besides a gray screen?

Very nice idea! Do you plan to send out some special seeds (like okra, etc.) as well?
Re:Perfect example of real-life hacking on Friday February 26, 2010 @11:28AM (#1153439)
I thought that "miles" is just a nice name for reward points: "Simply multiply the cost of your travel purchases by 100. For example, if your ticket costs $200, you’d multiply that by 100 to determine you need 20,000 miles to redeem."

In fact, in that story the guy might have had a lot of "miles", but it is only $12,500 in dollar equivalent. It means that this "great" hack is a hack, without "great". Please correct me if I am wrong.

I would be happy to test it - pls let me know.
Re:Don't Suck At Email on Wednesday December 09, 2009 @09:23PM (#987164)
It seems that there is more work associated with your option. If A = all emails, P = number of pending and A>>P, then

his method: click "unread" P times

yours: click "archive" A-P times

A-P >> P

His method is less work.

"costs $20-50k/year" - pardon, but where did you learn it from? Even if PhD students get tuition waivers, the waivers are given along with Teaching or Research Assistant positions. In other words, the PhD students are paid for some assistance, they are not just given the money. And Teaching Assistance at the university (especially, public school) might not be so much fun as it might seem. Not surprisingly, the percentage of Americans in graduate science programs is small.
I do not like to quench the excitement about Canadian immigration opportunities for skilled workers, but you guys really need to check the recent "improvements" in that process. Namely, the list of skilled workers has been recently (Feb, 2008) reduced to a couple dozens professions (http://www.cic.gc.ca/english/immigrate/skilled/apply-who-ins...). In particular, you really need to be a Cook or a Woodcutter with one year experience, to qualify now. Just my $0.02.
One day, carefully designed massive-multiplayer online games will provide better experimentation than agent-based modeling used now in economics. This article illustrates that EVE online is already one step closer to it, since they can introduce "governmental" policies and immediately see the impact on their ingame economy. Very neat!
There is an interesting documentary "Food matters" (http://foodmatters.tv/). The facts presented are astonishing. However, I do not necessarily advocate on taking their point of view, In my opinion it would be reasonable to withhold judgment and look on their facts. It might change your perspective.

The reason why it does not work with a regular XP media is that they (HP, DELL, etc.) install OEM-versions of Windows which: 1) checks for branded BIOS (HP, DELL, etc.) 2) installs from a special OEM-media

If you have DELL you might have luck downloading the image of their OEM-media (Pro or Home) and installing from it.

The most interesting aspect which they did not mention - how the nuclei of close contacts look like in the broader view. I wonder how it globally forms a high-connectivity core.

Here is a popular article about the characteristics of networks if someone is interested:
