What I mean is self-synchronizing like UTF-8. For example the first bit of a byte being 1 if its the start of an instruction and 0 otherwise. Just enough to know where the instruction starts are without having to decode the instructions up to that point and so that a jump to an address that's the middle of an instruction can raise a fault. Checking the security of x86 executables can be hard sometimes because reading a string of instructions started from address FOO will give you a stream of innocuous instructions whereas reading starting at address FOO+1 will give you a different stream of instructions that does something malicious.
I'm just distrustful of drives. All storage is essentially cache, and should be treated like it.

RxWebSockets – Starscream and RxSwift
Elixir is more than syntax. Or rather, it is not even about the syntax :) This is a common question, so I even gave a talk about it some time ago: https://www.youtube.com/watch?v=V5fMQcSy3y8

Elixir features meta-programming, structs and protocols, first-class documentation, strong focus on the tooling, some abstractions that make concurrency more accessible (such as tasks and streams), etc.

However, Erlang and Elixir share a lot! They have the same data-types (with the same names and even the same syntax for almost all of them), the runtime is the same, and the same foundation about processes, fault-tolerance and distribution.

My suggestion is to go with whatever "touches your heart" because, even if Elixir has its own features, they are more alike than they are different and most concepts you learn for one will also apply to the other.
I had the same feeling a few years ago when the sharing economy was the next big thing and people were prompted to subrent their flat, guest room, tools or car. Depending on who you'd ask, it was touted as the best (or the worst) of capitalism and communism combined.

I don't think "externalizing their costs to the consumers" really makes sense.

In an idealized market, costs should be passed onto the consumer. From what I can tell, the book you reference is just complaining that this cost changed from money to labor.

It is also worth noting that, in many cases, this results in a net win for the consumer. Eg, whwn I buy from a full service gas station, I am paying someone to pump my gas, and paying the to sit idle waiting for customers, and paying (in time) to wait for them to finish.

In contrast, in self service, the only cost from above I have is 1 person pumping gas (which switched from being paid with money, to being paid with labor)
> My former accountant had one too, he always took it on trips to France for holidays every year.

Oh, that's funny. The owners of the hostel we stayed at in the Netherlands used to do that, too. Apparently it was one of the V12 Jags from the 70s or 80s (Daimler Sovereign or XJ I think), and for good measure they had an after market trailer hitch attached, so they could bring their caravan along for the trip! I don't dare thinking about how much money that must've cost in fuel alone...
Perhaps, but perhaps not. If you've followed the news since 2001, you'll find that improper deletion of data is a theme that goes back a long time to the point where you should really question whether it's really an accident or the result of purposeful lack-of-enforcement of policy.

bought it earlier, read it pretty quickly. It's good, there is some gold in there and a lot of practical advice. It does feel a little bit expensive though, some sections are a little thin and this is made worse by the use of multiple blank pages between sections which makes it feel like the authors have padded it out.

On the other hand I'm likely to refer back to this book a lot over the next few years, so in that light $80 doesn't feel that bad.

I think I'd have preferred a living resource / subscription model rather than a one off book though.

The source material is still on Bloomberg's website. Look at it, its a 0402 Decoupling Capacitor: https://www.bloomberg.com/toaster/v2/charts/85c4e100b7ab4a8b...

The full article here: https://www.bloomberg.com/news/features/2018-10-04/the-big-h...

-------

As for what that thing is... its this (or something like this): https://www.digikey.com/product-detail/en/avx-corporation/W2...

That's an 8-pin decoupling capacitor. But there are "really" only 2-pins. The 8-pins are there to reduce resistance and inductance.

----------

Its very clear what happened. One expert probably said something like "The Chinese are using small chips to hack us". And a 2nd expert said "The smallest chip I know of is the 0402 chip-capacitor".

The reporters then combined the two expert opinions into an incorrect statement. I would NOT be surprised if the Chinese were using small chips to hack BMCs of SuperMicro (although there's no evidence of it... it would have at least been a believable story).

But as soon as I saw the above graphic, I just WTF'd at Bloomberg. The infographic was about as misleading and WRONG as you can get.
I recently had a similar SSD failure, although it wasn't in a "new fileserver" but my daily use 2013 desktop. It was working, then it was producing write errors corrupting my filesystem, then the whole system died, very quickly. Fortunately for me, some data was recoverable from the corrupted disk; I had a local backup from 12h prior, and a tarsnap backup from about the same time back.

(Um, here's where I have to be critical of tarsnap: their recovery performance is absolutely abysmal for small files. They're latency bound between you, their EC2 instance, and the backing S3 store. Think single or double digit kB/s and then think about how much data you back up with tarsnap. I can't recommend any other backup provider better, but this is an experience where tarsnap left me very disappointed.)

Looking at that SSD and my other SSDs' SMART data, they report extra blocks remaining in SMART, and you can monitor that as it goes down. Ideally you replace the drive before it gets to zero.

My primary mistake was simply not monitoring that data in an effective way.

I don't think anyone who monitors HDDs has any real expectation that the high-level SMART yes/no is going to protect them from data loss. Instead they look at highly predictive factors like "Reallocated_Sector_Ct" or "Raw_Read_Error_Rate" (or even plain old "Power_On_Hours").

For SSDs it's quite similar: Reallocated_Sector_Ct, Power_On_Hours_and_Msec, Available_Reservd_Space, Uncorrectable_Error_Cnt, Erase_Fail_Count, Workld_Media_Wear_Indic, Media_Wearout_Indicator. Maybe NAND_Writes_1GiB.

NVME SSDs provide SMART-like data on logpage 2 ("Available spare", "Percentage used", "Power on hours"). For some reason the NVME spec does not require media to accept host-initiated self-checks, so most NVMe drives don't have the same functionality as smartctl --test. :-(
Prague, Vienna, Berlín I guess
Where, what was it called?
I worked on SSD firmware for quite a long time and here is my perspective.

Early flash used to fairly reliable with almost minimal error correction. However with increasing density, smaller processes and multi level cells, it has gone progressively less reliable and slower. Here are some of the things that we need to worry about: https://www.flashmemorysummit.com/English/Collaterals/Procee...

To compensate for all these deficiencies, the SSD architecture and hence the entire FTL becomes very complicated because any part of it can become damaged at any time. We always have to have backup algorithms to recovery from any scenario. Its difficult to build algorithms that can recovery from arbitrary failures in a reasonable time. I cannot have a drive sitting around for 20 minutes trying to fsck itself.

Another problem is that the job while rewarding is not very lucrative. The chance of a multi million dollar payoff for an employee is low. I have a higher chance working on a web connected gadget to become a millionaire. So that means it is really hard to recruit those who are top notch programmers who known how to figure out the algorithms, write the code, debug the hardware. Most new grads these days are interested in python, javascript and machine learning.

Only a small fraction of Millennials would have been able to vote in 2000, and depending on your definition of the generation (stop date of '95 or '00) the full group either got to vote for the first time in the 2014 midterms or will get to vote for the first time in the 2020 elections.
You’d think the victims would have complained if it had ever happened, too. You can’t hide something like the Shuttle in orbit, so it’ll be clear to anyone who cares to observe.
Presuming it was him, the story would go like "I'll create a blatantly forged document that confirms a narrative that CBS wants to push and send it to them. I expect they will publish it immediately with no fact checking whatsoever, double down when called out on it, and the entire rest of the mainstream media will stick behind them."

Now if that's the story... I'm not saying Karl Rove is an angel or anything, but this seems like he's 10% bad and CBS news and every media source that stuck behind them is 90% bad.
Sorry, but this is just... True?

This seems implausible at first glance. Even making objects flat at the nanometer scale is quite difficult. When you also introduce movement tolerances (e.g. rotation disk is not perfectly aligned), this seems quite extraordinary.

It's a bit better than that from my reading: that quote's for He-3, which we don't expect to show any supersolidity (it's a fermion) unless the He-3 nuclei start forming pairs (the pair would have integer spin) -- which isn't really expected until even lower temperatures.

The key part of this experiment as far as I could tell was that at the same temperatures He-3 showed decreasing flow rate with decreasing temperature, He-4 showed increasing flow rate with decreasing temperature. This is exactly what we'd expect since He-4 nuclei are bosonic, while He-3 nuclei are fermionic. That's pretty good IMO
Yes, this is why us 10%ers have a responsibility to the 90%.

In the past, the wealthy created communal public spaces and affordable services of value. This is how they served the general public. Now, I see what used to be "every-person" activities re-cast as luxuries. Take your family out to a major league ball game? Take them out to the movies? What used to be cheap forms of entertainment will now set you back $100-200 bucks. Nowadays, for cheap entertainment, you have to take your family to see the bush league games, and you stay at home and rent movies when they go to streaming.

Yes, other things are cheaper. However, many of the things that go to having a sense of real physical community aren't getting cheaper, and social media, with all of its potential toxicity and truth warping is taking up more and more of our attention.
From my perspective, I see it as a different way of achieving the same end goal. With "serverless", someone still has to maintain servers somewhere and if your company is big enough, AWS is actually the more expensive option.

So if you are running your own infrastructure on bare metal, application development in erlang/elixir lets you better take advantage of the operations staff that you already have because running that infrastructure is much less complicated than the alternatives.

I already run my own authoritative nameservers and if I automated the maintenance and deployment of that, it'd only be an afternoon of hacking to make available to the public, and a weekend of hacking to add domain registration to it. I don't just work on sr.ht, too, so having a streamlined and integrated domain registration and DNS service would be great for my other projects.

Users and administrators almost certainly prefer a 20 minute IO latency over data corruption. Host operating systems should probably flag an IO as failed long before 20 minutes and then you know 1) nothing made it to disk and 2) have some chance to avoid introducing additional corruption, if e.g., the OS is smart enough to kick out the drive when this happens.

> I wouldn't buy an HDD from Amazon for instance due to their crazy shipping shit

I stopped buying anything electronic from Amazon because one power to USB adapter burned up, tripped a circuit breaker, and it broke my fridge. Luckily, that was the only other thing I had plugged into that circuit at the time.

Another big issue was my friend bought an Apple power adapter that started smoking after a few hours of it being plugged into the wall.

Scary stuff, especially when you consider anything that goes on or in your body could be counterfeit too.
I mean, that's all kind of bullshit, too. In the same sort of way that if you don't drive a Prius or aren't a vegan you contribute to climate change.

Gen X'ers and Baby Boomers didn't really do shit except live life in the time they did like Millennials and Gen Z'ers do now; it was the people in power who had impact.

There's too much pointing fingers in the wrong direction when it comes to these discussions. It wasn't my father who fucked my future over, though people elected during his time had significant impact on educational and housing policies today. You could say he voted for these things, but that's still painting an entire generation in the wrong light, sometimes you don't have a choice.

Imagine in the future blaming Millennials and Gen Z'ers for the problems in 2040 instead of blaming people like Trump and Macron. Incredible.

I remember I once searched for a domain name on Godaddy, and found that it was available. I waited a couple days before I decided on buying it, but next time I checked it was registered by Godaddy. If you wen to the address, you were directed to a website stating the domain has been "parked for your convenience", and you could buy it from them for now twice as much. I remember feeling so completely cheated I never did business with them again, and certainly never searched for available domains with them.

The problem with this line of reasoning -- "how do we know that each denial isn't just a sign of more coercion from powerful forces" -- isn't that it's impossible. It's that that it's unfalsifiable.

I got into a brief argument in comments here not too long ago about the saying "you can't prove a negative" which got bogged down in (what I considered to be) pedantic semantics; what we mean in practice is this kind of "negative." Instead of the conspiracy-minded folks providing proof that powerful, shadowy forces have come out in force against Bloomberg to discredit and suppress their reporting on an actual national security incident, they're demanding that skeptics prove that they haven't. And how can we do this? The complete lack of evidence for this happening might just mean that the shadowy, powerful forces are really good at hiding their tracks. We can posit that if they were really that powerful, they'd have suppressed the original reporting, but we can't prove that Bloomberg didn't just get lucky, or that their diligent, plucky reporters didn't somehow catch the Deep State off-guard for just a moment. We can point out that generally when we see this kind of story, other reporters in other organizations would have corroborated and even expanded the story by now, and that other reporters have said that they've tried and failed to do so. But that might mean the conspiracy is covering their tracks. That they've got to them. That the rest of the journalistic world is IN ON THE CONSPIRACY, MAN.

But it's also possible that the reason it increasingly looks like Bloomberg got played is that, well, Bloomberg got played. Like a cigar, sometimes a bad article is just a bad article.

The modern serverless paradigm is a way to give these more traditional computing runtimes/languages a lot of the features of Erlang/OTP.

The downside to having all of these things in services on the network and outside of the runtime is latency. Imagine a runtime where everything is a message, everything goes into inboxes/queues but passing many of those messages is zero-copy, doesn't hit a network interface, and going from the calling code to the called code isn't even a OS level context switch -- so the message is written to and read from a core/thread's local cache lines.
