"Note that any purchased Rebtel credit will expire after twelve (12) months of inactivity."

I'm one of their customers. My credit is gone without any reminders or notification. I have been left in dark until I tried to use the service yesterday and found out that my credit is gone. The credit is literally my money.

Comparing to what Skype does (https://support.skype.com/en/faq/FA10378/how-do-i-reactivate...), this is totally irresponsible and unacceptable to me. They provide no way of "reactivate" the credit.

So guys, be aware of such irresponsible service providers and check your provider's terms.

The foreign tax credit is an oil subsidy since the 'creative' oil companies started structuring their royalties to foreign governments as taxes, so they can deduct them against profits.

If Exxon has to pay a royalty of $1/barrel to Nigeria for access to their oil fields, rather than account for the royalty 'properly', they structure the deal to pay a $1/barrel tax to Nigeria. Then they can claim that they paid taxes instead of royalties and get the offset from the foreign tax credit.

From what I can see a process running in that "sandbox" would happily write to a file descriptor passed into it...

Like other posters in that thread I am very skeptical that this approach can be made secure and running with acceptable performance (given there are other more practical approaches to restrict processes available (namespaces, seccomp, SELinux...).
> Sorry, I do not see the similarity.

OK, let me try to explain better.

In your example, the only thing that prevents me to invest in the source A (with the ridiculously high EROEI) is how much other resources than energy I currently have. For example, say source A requires diamonds, which are expensive, and I can only afford a handful. But source A is much better investment than the source B, and I absolutely want to invest into A first (at the very least, I can sell the energy with much higher profit margin).

In my example, the only thing that prevents me to invest into higher-yielding asset (and we agree it's a good idea) is some additional limitation of reality (availability of resources), for example the size of the market.

So in both examples, there has to be an additional resource constraint, which prevents putting all investment into the higher-yielding enterprise. In the first example this limiting resource is money, in the 2nd example it cannot be money, but it can be something else.

So if ROI is a good way to compare investment opportunities, EROEI is a good way to compare energy sources.

> It may be more difficult to fake, but it does not answer the question what use the measure has.

An well-known example where ROI was faked is subsidies for ethanol as energy source. EROEI is less than 1, but because of the subsidies, ROI became larger than 1.

The EROEI would be an ultimate measure of where to put your effort (energy) if you were alone in the world and there were no other people. Then you wouldn't need money and could price everything in energy required to obtain it. Or equivalently, the world where people would collectively want to minimize the amount of effort they want to spend. Which is not quite the real world with money (the wealthy people for example can afford less effort than others), but it's useful as an approximation of it (and if you assume free market, then they are very close).

I think if you guys did the math, you'd find that some cheap chinese solar panels + a battery would be way cheaper than running a generator.

While I agree with you for the technical merits of nuclear, I think nuclear has lost for several reasons. One of them, a cultural shift towards decentralization.

I'd say under 10,000 GWh/day required, because:

a) The LLNL flow charts are for primary energy, not energy services; an electric vehicle can travel further on a megajoule of electricity than an internal combustion vehicle can travel on a megajoule of diesel fuel.

b) Long distance shipping, airlines, and (probably) long distance trucking are not going to replace liquid fuels with batteries. Either there's going to be residual use of fossils for those smaller applications or electricity will be used to make synthetic liquids; either way those segments aren't going to contribute to battery requirements.
This looks very much similar to HP CDA (Continuous Delivery Automation), the project was later scrapped. Wish they had open sourced it.
I found the post slightly contradictory but overall strongly evoked the frustration that the author felt. My reading is that most of the problems come from a lack of manpower or perhaps a lack of delegation but I'm only reading this as an outsider. I think that D is a language that I would like to use but I don't because few seem to have heard of it. This is the catch22 problem that D finds itself in. Popularity contests are fickle and not just restricted to the high school playground unfortunately. Look at swift, i read about problems with breaking changes and compiler crashes and it just doesn't seem to matter because Apple.

Anyway, my question is, what are the weak points of D? I should state at the outset that I have no problem with there being a GC as I'm a python programmer not a C programmer but one who wants to learn a compiled language. I'm more interested in any other issues that might warn me away from D.

Guys. It's embarrassing that this is a top article on Hacker News.

There is really no association between the price of oil & the price of solar.

Oil is an expensive form of energy because it is portable & used for transportation. It competes with the price of lithium ion batteries.

Solar is for generating electricity. It competes with coal, gas, geo, hydro, wind.

And don't come back at this with some pathetic reasoning that on some islands or remote places idiots use generators. I say idiots because generators are loud, smell, need maintenance and these days are probably quite a bit more expensive than a solar + battery system.
The larger size iPad Pro is an amazing drawing tablet, I’m really glad to have one. I’d recommend one to anyone trying to take notes with a pen, make sketches, design anything (from furniture to web apps), work as an illustrator, etc. I find the pen and display to beat anything else available right now, unless you need a very large display.

There’s definitely room for software to catch up for other types of uses, but that’s more a matter of third party developers stepping up. (And the general poor market / software ecosystem on the iPad, with relatively weak sales of pro apps in general.)

Don’t expect it to be a laptop replacement. (I know some people who have had success with this, but for me the uses of iPad and laptop are almost entirely non-overlapping.)

It’s also great for watching video, and I have friends who have enjoyed playing games on one.

I think we need to ensure people pay attention, instead of adding even more information to these systems.

Sure, we could add warnings for potentially dangerous railroad crossings (e.g. those that do not have a signal installation), and other dangerous places, but how to ensure that people do not rely even more on their systems and after a crash argue that their system did not warn them of this particular situation?

I know a street segment that is constantly blocked by trucks which blindly followed the GPS to a bridge they can't pass and turning around is almost impossible, although multiple signs warned them. Now and then a truck takes down the roof of the bridge, although a HUGE sign says it will be too low. Before the prevalence of the GPS, this almost never happened AFAIK, and the drivers always blame the GPS.

What about people driving off cliffs, into lakes, or as stated in the article, along blocked streets. If a guy puts up a sign that this street is closed, it is closed and you need to follow, no matter what your GPS tells you. The sign or any legal representative is the normative authority and you must obey - the GPS is merely assisting you.

Drivers need to pay attention - and they might have to learn to do it despite having an assisting device giving them directions.
Instead of warnings, can I get the apps to please know where the crossings are and just avoid them if it doesn't cost too much time penalty?

(E.G. if there is a bridge near by that was built to avoid that issue, send me to it)

D is C++ but improved/simplified. Its not to hard to get into, its more easy for anybody from a C background.

The main virtue of C++ is its vast legacy base that needs to be maintained. Replacing C++ with D can't possibly be for the reason of being "improved/simplified".

I have been using Blue Ocean as the radiator view for our Jenkins projects for a long while now and it does look really nice and sleek. That said, currently that's pretty much the extend it can be used for. I'd say it has about ~5% feature parity with the "old" UI currently, which means that there's not much to do than just look at the pretty progress bars. Can't wait for this to progress though, the old UI of Jenkins is archaic at best.

A weird thing is that northern countries such as Sweden, at or near the polar circle, are often considered dark and unsuitable for solar. But the thing is, during summer the sun shines 24/7 ... so there would be a lot of power during mid summer and no (solar) power during mid winter.
Thinkpads: new models are going to be presented in January, so it might be worth waiting for CES and checking if one of the new models sounds like a great improvement over the current ones worth waiting for.

If you do image editing you have to be careful with Thinkpads, the color space of recent screens has been quite bad in some models. Completely fine for coding etc though.

Actually, this pumping water idea is considered in solar.

During the day, energy is used also to pump water behind a dam. At night, when the solar output is null, the water is released and produces power via normal hydro turbines.

For example in Romania, which produces exces power [1] almost all the time, there is a plan to build a huge reservoir in mountains to use this power to pump water from the major rivers into it, thus building a reserve energy store.[2]

In my career I worked on three C++ projects with about 100 developers, and OOP proven to be useful. If the codebase is so large that not a single person knows it as a whole, OOP allows to express the structure of the code. I surely wouldn't want to do it in C. The only drawback I noticed is that you need to learn more to understand and be proficient in C++.

It's not very hard, it's just impractical. Mainly because a database is a giant bag of statefulness (to put it scientifically).

You need to prepare test data, you need to update and maintain the test data. That is already a big barrier to entry.

The actual testing involves three simple steps: setting the initial state of the database, run your queries/procs, verify the results. This will be unbearably slow even for a small test set. So you start to make things complicated by trying to be smart, like only revert the state you modified, or using SQLite for tests and Postgres for production, or by running the database server on a RAM filesystem, etc, etc.

I've seen a few people go down the rabbit hole and noone came up with a solution I could be happy with.

Hobbies, like everything else, have opportunity costs attached, which even applies just between hobbies (e.g. practicing your X more happens to the detriment of Y, your other hobby), but obviously also between hobbies and work or other lifestyle choices.

There are tons of people whose hobbies have run afoul of their work, or family relations, or health, etc, as the effort, time, etc, for doing a hobby could apply to any of those other things.

Zuckerberg’s Jarvis home AI is like an Alexa that learns your musical tastes
According to [1] there was a system in 1968 that “consistently outperformed humans when presented with the same recognition tasks”.

As someone who was into programming and electronics in the eighties, I also feel a need to object whenever people say things like “we thought it was AI until we could make a computer do it, and now it’s just math” (paraphrasing).

We (those of us interested in the subject back then) had a pretty good idea about what would be possible in the future (because of faster machines and more storage) and what would not be possible in the future (unless a breakthrough was made in understanding intelligence).

Now, I do think we underestimated how fast things have developed, and especially the resources people have access today via the internet, but none of what I have seen today would have been classified as AI by myself back in the eighties.
