> The problem is, processes share code all the time, via shared libs, which makes Spectre attacks able to cross process boundaries.

I don't think that is how it works. Just because multiple processes map the same code (read-only) doesn't mean that they also have mappings to each others' data. If two processes shared mappings to the same data (e.g. after a fork() with no exec()) then what you say may be true.

Just because I can write a program that uses libc doesn't mean that I can use that as a means to extract ssh keys from an ssh-agent that also is using libc.
Re: power cycling, I noticed a similar problem when I reviewed Ford/MS’s SYNC system 10 years ago: if I pressed the phone button without a phone linked, I would be locked out of the sound system until I turned the engine off and on again. What?

nowhere. Both Intel and AMD have processor level "malware".
If the revenue is there, it’s a no brainer to build out your own data center or acquire prebuilt space. Cloud provider margins become your cost savings (clearly, as evidenced by this article). You’re going to need infrastructure people regardless, whether it’s on-prem expertise or AWS/Azure.

It’s disingenuous to inflate the compensation for datacenter employees as a boogie man, or to wave away a “modern cloud DC” as a Herculean undertaking. There rarely is any R&D required, and stock compensation isn’t always necessary.
That's a great catch, I didn't notice that while reading the papers. Here's one that cites Polat's papers, but doesn't seem directly influenced by GlassesOff: https://www.sciencedirect.com/science/article/pii/S004269891...
Yes-ish. There are two reasons we are living inside an event horizon. First the accelerating expansion of the universe means that light emitted from earth now will never reach most of the observable universe. We can look up and see galaxies that are already beyond our cone of influence. That is the primary effect. But a secondary effect is that the mass of the universe (Big Bang remains) is sufficient even though not dense as to bend light emitted from it back onto a closed trajectory. So if there is any void beyond the cosmos that we see , observers in that void would see us—our entire observable universe—as a black hole.
It's funny because publishers are otherwise quick to sue Google for their other aggregator and caching features such as Google news and recently the "view image" removal. But with amp they happily bend over.
Entirely untested and just spitballing... use Firehose to concat a bunch of small files and store based on size or time passage as a larger file to s3.

Then use Lambda transform in firehose to index the byte ranges for each record (file)? (Biggest q in the process would be here... you might have to index after it hits s3)

S3 also allows the Range request header out of the box as well.

Interesting problem, and I can totally related with s3 put costs be astronomical.
I can't believe I read that entire train wreck front to back. If IOTA published this to "expose" MIT, it does quite the opposite. Rule number one, all together now, don't roll your own crypto.

I think I work with a clone of Sergey. He has somehow managed to convince his boss that he knows what he is doing. Every interaction with him is painful as he subconcsiously does everything in his power to discredit me and make himself look good.
We have two of those, as good as they are I wouldn't trust them on an external door[0]. The locking mechanism has to be fairly light weight due to being driven by an actuator and a battery operated one at that, which means instead of a deadbolt-like configuration it is a traditional spring Latch, which could make it susceptible to bumping or even a strong rare earth magnet. Plus the key is pretty simple.

Ask HN: Defunct Startup, how to deal with investor, how to wind down?
I ran a US company and due to unforeseen circumstances, I was unable to return the country to raise an additional round of funding and the company collapsed.

There is currently one angel investor at $150k, some debt holders ~$10k.

I called the investor a year ago and said to him that I want to close down the company -- all the employees have left. We agreed that he'd try to solicit around the company to his contacts and try to get a sale.

I helped to pitch over the phone a once and did maintenance when here and there, and he's mentioned several people he's shown it to but never any reply.

I told him I was going back to school and need him to take over the AWS charges, which he did. I forgot to ask him to take over the domain fees and database charges and have been carrying them myself (student loan).

The company hasn't paid any taxes since its inception (I read online that I don't need to if the company is running a loss every year). I haven't filed a statement of information for a year now, and I'm effectively locked out of the country. The company bank SVB closed the company account due to inactivity.

The investor's lawyer did most of the paper work to get the company up and running. He has most of the documents, and I don't really know how this works. Unfortunately, I couldn't pay his last legal bill.

The fund holding the $10K debt has gone silent on me, and I've been afraid to bring anything up.

Recently AWS suspended the account due to overdue payment. I contacted the investor two weeks ago, and he said he'll take care of it. A week later I noticed it's still not fixed, so I contacted him again, asked if he was tabling things, and that if he was, perhaps I could also pause my payment on the DB (bringing it up the first time). No response for a week.

Anyway, what do I do here? Am I at risk for anything?
I'd rather see a figure of how much more money they MADE than how much they saved by doing something that is not directly related to making more money.
I never got the impression this was intended to surprise or trick anyone because it's far too obvious. It just feels like a way to make the subject matter vaguely interesting to the average reader.
It would be fairly natural to have a small three-way switch onto each light to select between "central control", "override on" and "manual override off", in that order.

That way, you wouldn't have to shut down the entire system.
This is all well and good, but to recast this to 2018, you need to factor in the people who can't recognize fascistic tendencies unless they come with a swastika on their sleeve.

You see it in both the obsession to label anything and anyone a nazi or nazi-adjacent, as well as to turn a blind eye to the real abusive power wielded in the name of anti-fascism.

The ends do not justify the means, and you don't get to paint your team's actions as merely "consequences" like it's some sort of divine and just punishment. You can't cast yourself as a powerless observer when you're actively applying leverage in collusion with institutions.

Consistent rules, actual accountability and real responsibility need to apply to everyone if this is to get better.

Do they still use AWS for compute, with their own data center just for storage? Or do they have their own infrastructure for compute?

If I remember correctly, they noticed they could dust costs significantly in storage compared to S3 because the vast majority of files in your Dropbox folder just sit there and hardly need to be read or written again (photos, etc.).

If they’re not using AWS for compute, it’d be interesting to see what sort of similar reasoning they have for why the costs are cheaper in house.
Fascinating read.

I think we've all worked with a Sergey in our careers so far. And most of us end up doing what Ethan did.

Those are definitely two good reasons, but I think there's another: you are starting up and your core competency isn't object storage.

I'd argue that the core competency of Dropbox is its easy syncing. Dropbox wanted to get that to market quickly. If they had spent the time building out a data storage solution on their own, it would have meant months or years of work before they had a reliable product. Paying AWS means giving Amazon some premium, but it also means that you don't have to build out that item. It's not only about economies of scale and rapid demand. It's also about time to market.

I think it's a reasonable strategy to calculate out something along the lines of "we can pay Amazon $3N to store our data or store it ourselves for $N. However, it will take a year to build a reliable, distributed data store and we don't even know if customers want our product yet. So, let's build it on Amazon and if we get traction, we'll migrate."

S3 is a value-added service and creating your own S3 means sinking time. Even though data storage is very very near to Dropbox's core competency, it's really the syncing that was the selling point of Dropbox. To get that syncing product in front of customers as fast as possible, leveraging S3 made a lot of sense. It gave them a much faster time to market.

As time went on, they had traction, and S3 costs mounted, it made sense for them to start investing in their own data storage.

It's about figuring out what's important (the syncing is the product) and figuring out what will help you go to market fast (S3) and figuring out how to lower costs after you have traction (transitioning to in-house storage).

Yes, a lot of companies use cloud services when they don't need them. However, Google Cloud's compute pricing is reasonably similar to DigitalOcean (with sustained usage discounts) and from what I hear these companies will often negotiate discounts. AWS can seem a bit pricy compared to alternatives, but I'm guessing that Amazon offers just enough discounts to large customers that they look at the cost of running their own stuff and the cost of migration and Amazon doesn't look so bad.

Still, when you're trying to go to market, you don't want to be distracted building pieces that customers don't care about when you can rent it from Amazon for reasonable rates. You haven't even proven that someone wants your product yet and your time is better spent on delivering what the customers want rather than infrastructure that saves costs. As you mature as a company, the calculus can change and Dropbox seems to have hit that transition quite well.
Nowadays, you don't need to do that yourself to run a cloud because you have companies like Joyent offering fully managed private clouds at a fraction of the cost of AWS. They will rack and stack, manage the cloud software, provide escape plans so you aren't locked into them as a vendor and provide architectural guidance to your app teams.

DISCLOSURE - I am a Joyent employee.
Then you ban Christmas trees in public schools, because it might hurt feelings of Muslims

Here’s the thing tho’: a good observant Muslim knows perfectly well what a religious holiday is, and recognises Christianity as a fellow Abrahamic religion, and is no more offended by Christmas than if you wished him or her Eid Mubarak.

The only people offended by Christmas are white left-wing atheists, and it is deeply problematic, and racist, how they use Muslims as a scapegoat.
I feel after getting to a certain scale moving to your own data center is a very smart choice. Its all about how well you can run your data center there after. So, good for them for scoping it out and saving money.
I think most of the self-help is full of jargon and find what is valuable to you. I recently got a copy of Daniel Goleman's Emotional Intelligence and it is a long, laborious read with barely 1 page of actionable items.
I suppose the difference is that people who know about cryptography think that the iota team obviously don't know what they're doing, and people who don't understand cryptography and have a financial stake in iota not being worthless feel differently.

I've taken some cryptography classes and a graduate level cryptanalysis course, and I could immediately tell that the people on the iota side clearly don't know what they're doing. For example, this should trip anyone's bullshit detector:

The X was basically designed for China, you can’t show off with a design that is 3 generations old already! Apple didn’t bother updating their ID for 3 years (6, 6s, 7), which is why sales were so tepid in China for the last two years. The X fixed that.

The effect of iCloud moving will be mostly neutral. As long as WeChat continues to work on iPhone, whatever iCloud does won’t be very significant. I doubt most iPhone users in china even know what iCloud is.
Pre-addressing these problems won't make shy person instantly not shy. It wont make controlling person not controlling nor change someone who is not self aware or don't think much about others.

While these exist in workplace too, setup is different, goals are different and dynamic is completely different. And you can usually find yourself non-group setup with own accountability and tasks.

Most important difference is that in school you are supposed to learn and this turns whole thing to waste of time where you don't learn - and then you miss stuff you was supposed to learn.

I've seen televisions have that issue. They can come back on in the middle of the night. To me, this makes sense for a lightbulb. If your failsafe "backdoor" expects it to be wired to a switch, you would turn that switch off in the event of a power outage. What else would it do when the power comes back on?

One thing I really like about "smart" things, when the power is out at home I can check my phone to see if power is restored. I guess that's similar to calling your home to see if the answering machine is back on.
Oh! I remembered more details about it if it helps. It has to do with e being the "most efficient" numbering base. The reason e is the "most efficient" has to do with wanting to minimize both the size of the alphabet of symbols as well as the number of digits in an average computation. If you allow for a non-integer base, and a non-integer number of digits, the optimum base is e. e rounds to 3. ;-)

The numbers within the EU and EEA are PPP adjusted not that badly off.

With extremes like that you might as well compare it with Detroit or if we don’t stick to the EU might as well compare with Mexico.
Hmm, just a quick clarification for the first approach. It says that the replay operation may then introduce significant load on the primary node. Is this because when new nodes are added, the logs have to be dumped to the new slave nodes from the beginning, and the IO to do so is expensive, possibly interfering with normal operation of the master node?

Well, there was a hospital in India, that when a patient came in feeling unwell in his abdomen and then ...

a) somehow this patient developed a ruptured liver and severe trauma to the skull (given that he survived the flight and was conscious we can easily conclude that neither injury was present before the hospital got involved)

b) missed that someone at the hospital has removed the heart and kidneys from the patient

c) signed off on a "natural causes" death certificate, no mention of what happened to the organs

(note that organs for transplant need to be taken out before death occurs, so it's not like they removed them with the family's permission after clinical death)

d) refuses to investigate how this happened

e) got the government to concur, and actually the government is helping them with d)

That's something that got reported last week, and this was a hospital in India, so third world healthcare.

> which reduced spending on “our third-party datacenter service provider” by $92.5 million offset by increased expenses of $53 million for its own data centers.

They reduced spending on AWS by $92.5M, but still store 10% of data there so ~$103M?

Looking at the $53M cost for their data center vs the $92.5M decrease to the "third-party datacenter", they saved around 43% moving to their own data centers.
TIL that Qbasic has structure types (user defined types) https://en.wikibooks.org/wiki/QBasic/Arrays_and_Types#User-d...

If it had functions as values then it would have had object based programming.

i think the good part about basic was that it supports both unstructured programming with goto/gosub (gets you going quickly) and structured programming (if you don't use goto/gosub and write functions). Maybe we lost this multi paradigm aspect with later (more powerful) languages.

That may have been because of Dijkstra and his 'goto considered harmful' rant : authors of programming languages do not like to support the unstructured paradigm out of fear that they will be taken as a not-so-serious-programming language. Somehow they did not take notice that unstructured programming is quite good as a teaching method and that one can choose not to use goto when it is available. I really don't think that it is such a strong habit that is impossible to unlearn. It is far easier not to learn how to program at all...

This is quite shocking and I am sure it’s not a pattern. My compensation has doubled roughly 6 years over similar period in inflation adjusted dollars and I have considered it as slow growth. Note that most of this is without climbing up management ladder. Most of my friends have also experienced doubling every 5-7 years as far as I can. There are few folks who haven’t moved much but that’s usually because they didn’t kept up with tech or kept chasing next startup or find non dev roles where they can excel. Living in SF/bay below $200K is quite unimaginable these days.
The best part is that part of their argument for why it's not a real vulnerability is that the coordinator might have rejected it - except that the coordinator is essentially a server run by them, which makes the entire "crypto" part of crypto currency totally unnecessary.

>> The SR71 was built in the 50s

The SR-71 is a 60's era aircraft. First flight in 64. Its predecessor, the A-12, flew in 62 with construction starting in Sept. 1960. Prior to that these aircraft were a series of paper designs beginning in the late 50's. Early versions of the J-58 were run in the late 50's, but these early engines were not flown in A-12/SR-71; substantial rework was needed to sustain mach 3.
Bad news: GPS in airplanes is the least complicated piece of kit, and most commercial aviation is literally fly-by-wire.
