"One appealing aspect of LMDB is its relative ease of use from multiple processes, above and beyond its basic capabilities as yet-another-fast-key-value-store."

simdb is only lock free and thread safe. While LMDB is benchmarked at around 10k writes, this should be able to do millions of mixed reads and writes with 4 modern cores. LMDB seems to use a separate lock file to sync multiple threads/processes. The only catch here is that the keys aren't sorted, which doesn't seem to be a requirement of theirs.

That's really interesting, than you for sharing.
The easiest scenario to imagine is a hardware failure or power outage. The database was in the middle of doing something, and then was prevented by a hard drive dying or the lights going out. One way to test such a thing is to literally unplug the computer to see how it handles the failure.

So, let's say you have a client/server application... the client is telling the server (database) to write some records to the database. In the middle of the write, you pull the plug. Some questions you'd want to know: what does the database look like when it restarts? Can we read it? What is the current state? Did any of the new data get written? What does the client think was written? If there was an uncommitted database transaction, was the database left unaltered?

It's just as important to test the client in these scenarios. While the server may have crashed, what does the client think happened? Was it waiting for an ACK or "OK" message? Did it get the message? If the update failed, what does the client do in that situation?

Things can get even more complicated if you're thinking of replication across different servers. If one of the servers fails, how does the replication work? Do sessions fail over to other servers? How many servers are required? If there was a corrupted record, did it propagate or was it scrubbed?

This is something that is only necessary for legacy databases. Modern database providers give you gateways that deal with a huge number of connections with no issues.
The Story of Spoffle
Good point, but one small nitpick. Combined-cycle plants are optimized for efficiency, at the expense of ramp speed, so they are not really used as peakers. Gas turbine plants are what you are thinking of; basically, a jet engine with a generator attached. Right on for the rest.
I totally agree. What a generic, worthless tagline: “Make your website better”. Better how?

Tesla proved the EV market and made EVs sexy and cool, which is helping tip EVs into the mass market. Without Tesla you wouldn't see BMW, Mercedes, VW, Nissan, etc. making mass market and luxury EVs. They'd be making no EVs at all or awful "compliance cars" designed to be undesirable. (The traditional auto industry is full of ICE heads and hates EVs. They have to be dragged kicking and screaming.)

If EVs weren't tipping we'd still be talking about how peak oil (the depletion of easy/cheap oil) means the end of modern transportation.

Tesla didn't make Musk a billionaire. The PayPal acquisition did that.

Does Tesla even still get subsidies? They got that DOE loan years ago but they paid it back and lots of other auto makers got government loans back then too. Or are you referring to EV tax credits? In that case those are also subsidizing Nissan, BMW, GM, and any other company selling a mass market EV.

Yes! There's wind! And pumping water up a mountain as storage.

I'm a fan of LFTR reactors and similar new designs, but the writing is on the wall for nuclear power. Alternative energy shot by it. I still think we should invest in Thorium reactors at the state level, but solar/wind energy has won.
good question so I found this[1] faq which says:

Using a Falcon 9 at 25 satellites per launch it would take 177 flights, about 36 flights per year.
Using a Falcon Heavy with 40 satellites it would take 112 flights, over 5 years that's about 22 flights per year.
Using a BFR assuming 350 satellites per launch, until someone comes up with a better number, would need 13 flights total.

now those are based on the old higher orbit so presumably the numbers move substantially with this new plan.

Sure. Solar and batteries alone cannot do that.

But solar, batteries, wind, thermal, hydro, gas etc all connected via continent wide digital grids definitely can. And it's the option that nicely avoids the NIMBY problem you get with nuclear.
I would really encourage you to get your resume to match a traditional one page format. Something clean, professional and orderly ( https://zety.com/blog/resume-formats is just a search that seems to have some).

If it doesn't look professional, it isn't something that scans well, well, it doesn't get the appropriate information across in a timely manner. That itself is an important skill.

Consider also that France (you list your address as France) has unemployment at about 9% and youth unemployment rate at about 20%. That may not be the best place to be looking for a job.

Even with being some place for 4 years, it doesn't look like you are someone that will stay in one place long enough to recoup the cost of training a person up to the appropriate skill. This applies to everything from the farm hand and fast food (where you're also competing with that youth unemployment rate) to professional jobs. It costs money to onboard someone - even farm hand. If you aren't going to be there for a year, hiring someone who isn't going to stay is likely to lose money.

That "I'm going to go" isn't only communicated with your scattering of locations and durations, but also the volunteer experience listing CouchSurfing weekly as the top item. This is reinforced with the current extracurricular (you're not a student anymore - they're hobbies if that) listing two items... one of which is couch surfing.

If you want a programming job, computer programing isn't a 'personal interest' listed near the end of the second page - it's a first page top item.

Listing "Ideas" and then having it go to a basically empty page... that doesn't inspire any confidence. Note also that ideas are cheap - it's the implementation of those ideas that demonstrate skill. Maybe there are ideas behind the links in the upper right, but as it is, that's a blank white page.

Of these, the most important I would say is make a boring resume - something that follows the form. No, it doesn't make you stand out, but it also is something that is easy to scan and demonstrates professionalism in communication and presentation.
You'll find that nothing could bring us closer to this vision than making compute so remarkably inexpensive and scalable, out of the box, for everyone :) This is why serverless is so exciting to us.
This company sees the intermittent nature of renewables as a the primary problem, but that's thinking left over from the last century, a century where you couldn't make the demand responsive to the supply. That's going to change; the biggest amounts of home load will be heating/cooling of air for the home and water heating. Both of these will be demand responsive. And as cars electrify, that's another huge amount of load that will be responsive. The only thing left is the business model to pay consumers to charge/heat/cool at the right time. We don't even need that many additional batteries because thermal storage is cheap, and an electric car will store 2-3 days of electricity usage, and most people come nowhere close to needing a full 60 kWh of electric driving every day. Those that do will use it, but those that can be more responsive to when they charge will get paid for it.

In the 20th century storage was super expensive, and large precise construction was inexpensive; that's being flipped. In five years, solar plus enough lithium ion storage (or other tech) will be cheaper than the cheapest nuclear. In 10-15, winter levels of sunlight + storage will be cheaper than the cheapest nuclear. They're trying to address the problems of toady, in 20 years. If their development pipeline is 20 years out, they need to anticipate the problems 20 years out, rather than skating to where the puck is now.

The problem has changed; there will be niche needs for nuclear power, I'm sure, but unless they can drive down current nuclear costs to be cheaper than wind or solar, there's going to be little need for nuclear at all.
Apologies I wasn't clear. When I say CCGT can throttle quickly, I compare it to coal and nuclear ("legacy thermal", if you will), not peakers that can ramp in minutes from 0-250MW of output. Appreciate the call out on my ambiguity.

Everything I've read about the duck curve in California and how ISO manages it has indicated that CCGTs are ramping "fast" (~13GW in 3 hours [1]), but I suppose it's all relative.

Rust version has 10% of lines marked as `unsafe`. Programmers need to make 10 times more errors per line to introduce the same number of errors that are considered unsafe in Rust (memory corruption, data races, double frees, deallocated memory usage). I'm not sure what's wrong with this statement.

Want to know my personal favorite? It's ConferenceBadge [1]. The design is clean and the page is very snappy. But what I absolutely love is how they answer every question that I might have on the landing page itself. I am not personally a fan of Close.io's that sells itself as "close more deals," but doesn't answer how.

I think a landing page should answer what it does, and how it does it in very unambiguous terms. Too bad so many SaaS companies try to make promises without giving an idea on how they'll deliver them.

The article you cited said we need 43,000 square miles of solar to power the earth costing 5 trillion dollars, I consider that to be a huge amount of land and money. That would be half the area of Minnesota the state I live in devoted entirely to solar panels. Sure it wouldn't all be in one place but that is still a significant amount of land world wide that have to change land uses.

Also isn't that article also assuming that all of the solar panels would be in the Sahara desert? Where solar power is extremely efficient. If we spread these solar panels across the world we would need significantly more because they would located in places much less suitable for solar power.
We are all allowed to have different subjective experiences. Nobody is "wrong" here.
What about client-side apps? Is it possible to write a cross platform client app with .NET Core, a la Electron way? That would be my dream framework. I've been waiting for it for decades, seriously.

Holy cow, that's an _amazing_ landing page! So effective.
This is interesting, although not that novel. Marshal deserialization has always been unsafe, and in > 10 years as a Ruby engineer I’ve never seen it used in a production system. I would guess that finding a system vulnerable to this exploit would be a more interesting story than the exploit itself.
You'd be surprised by how often I've seen a database fail in prod simply because it ran out of disk space. In both cases monitoring software was running but misconfigured.

What the parent comment is correctly saying is that for certain databases (that are oriented around stateful connections) you might benefit from a infrastructure-level optimization.

However, this is not the case for all databases. Furthermore, modern database vendors are extremely motivated to address the serverless usecase
Australia <-> India Skype has become awful for us in the last 6 months or so. Does anyone know if this is related?
Wow 6 months activity and they pull the account? Not criticizing at this moment in time but it certainly has its good and its bad.

That being said, it seems like they expect some level of activity in the form of engagement (comments? posts?) to keep the account as wel. Ok this seems...maybe reasonable.

However will be concerning to see what China does in this regard. Might they require users to post at least two happy statuses a day, or else you aren’t being “active”? You could then have your social credit score deducted. Or maybe you have to criticize at least one other person for not being loyal enough to the party on their FB wall. This could create a kind of social network dystopia nightmare that we’ve only begun to understand in the West.
No one is saying to make voting "harder," the question is when does it become so easy that you no longer take your civic duty seriously. Mob and cult mentality are incredibly common in online and reality TV voting, do you honestly think people don't devolve into that in national politics? I think that is a naive world view.

Also, that sentiment was driven by racism, not by actual intelligence. If you look up those old tests, there were some questions with no right answer, etc.

Please please explain how rekognition aids ICE in caging children. This is indeed a strawman, unless you prove a direct connection.

And then there's the deathly silence on actual evidence that a majority of Amazonians even want this. Instead, it's very likely the voice of a radical, but vocal minority, quite literally blackmailing the company.

Here's the blackmail clause - "deny ICE rekognition access, or we'll leak confidential company information to BuzzFeed (and the media) and make a hit piece of your policy in an echo chamber that sympathizes with our politics"

I could give a crap about conservatives protesting companies for politician reasons. I don't believe a baker should be able to deny a gay couple a wedding cake, and I certainly don't believe Amazon or valley intersectionaliats should have the power to deny the government of the United States, whose policies have checks and balances in 3 branches of governece, access to tech.

If, on the contrary, you proposed a legal challenge in the courts on constitutional merits, I'd support that. But this power trip of valley intersectionaliats de-platforming everything they disagree with is exhausting, in a free and mature democracy like the US.

Can you prove that? Just logically, if you could vote from your smartphone at 7PM on election night from your couch, do you think that would make people who are more informed vote or that it would attract people who are less informed? I know it sounds insane, but sometimes making people have some sort of motivation to physically move, can be a good thing.
Indeed. There are countries already at 100% zero carbon for electrical generation through the use of solar, wind, hydro, and geothermal:

https://www.electricitymap.org/?wind=false&solar=false&page=...

There is no reason we cannot rapidly expand on this with additional solar and wind, as well as batteries as the cost drops.

No, that's PUE - a measure of the overall efficiency of computing. Today's leading datacenters have a PUE of about 1.12, meaning 12% of their total power is spent on non-compute things (losses in electrical conversion and cooling, for the most part).

A decade ago, PUE numbers were much more commonly closer to 2, (Google's were in the 1.2-1.3 range even in 2008, but things had improved quite a bit since 2005 already, and MSFT and YHOO were working on it), but modern datacenter design has improved that substantially.

I figure that’s a good opening for accessory sales (from a product design perspective). It wouldn’t have to lock you into a phone if the connector was universal (ie, the switch to USB C) and adapters to fit snugly into the slot—they could even be cases. Also has the advantage of modularizing the machine.

And most phones swing above chromebooks for price and power, no? This would be an improvement on the format if you ask me. Especially if it could eventually deliver a proper Linux distro or Mac OS.

CS50x on edx is probably the best introduction to CS and programming available online. He really can't go wrong with that.

If he's not in a rush, he would probably benefit from first reading and working through How to Design Programs by the Racket folks. It covers higher-level concepts than CS50 that would benefit programmers of any level and uses a series of Lisp-y languages to do so. The design process it teaches will allow him to program more systematically and prepare him to tackle other programming courses.

They are scarily strong.

A few years ago. I woke up vomiting and in extreme pain. Housemate drove me to 24 hour clinic. I was stuck in waiting room for hour or so. Eventually I got to see doctor. Clinic was not really confidant they knew what was wrong with me and told my housemate to take me to the hospital. I was stuck for another hour or two in waiting room at hospital all the while in extreme pain and vomiting.

I was diagnosed with a kidney stone and I was given a morphine drip. Almost immediately I was out like a light I don't even remember drifting off - scarily strong stuff I went from worst pain of my life to sleeping like a baby.

AbeBooks is a great place to buy the non-US versions of textbooks (which are almost always identical to the US version, but in grayscale rather than in color).

For instance, on Amazon, the K&R C Programming book goes for $28.52 used, $61.74 new, or $28.70 for a one semester rental [0]. For a book that hasn't changed since 1988, these prices are absurd.

While as on AbeBooks, the international edition goes for $10-11 [1].

Current AMZN employee here. I can anecdotally say that I personally see no problem with selling the technology.

There was a extremely active discussion on an internal mailing list when "the letter" came out that was signed "Amazonians." While there were a small number of very vocal proponents of stopping the sale of the technology, the prevailing opinion was split between indifference and anger by less than 400, mostly young and relatively new Amazon employees, representing themselves as anywhere near a significant portion of "Amazonians" (however much that was intended versus sensationalism, I refuse to speculate).
