> This smells an awful lot like an impossible infinite compression claim; any real compressor must increase the length of at least some inputs due to the pigeonhole principle.

Why even include this sentence when the rest of the post is about the extra state it uses to track collisions?

> Including just one bit of metadata per cache line of memory is 32MiB, more than the 0.75 bits/line (24MiB) calculated on page 5 for the scheme they would like to replace.

Sure? The point of this scheme is to not store any metadata per line of main memory.

> Their next bit of handwavium is that they use "DES" to choose line markers in a way dependent on a secret key which can be changed in case of a LUT overflow. I wasn't immediately able to find a modern figure on how fast hardware "DES" is, but a 2003 paper gives a figure of "21 to 37 cycles of latency" https://www.intopix.com/Ressources/WPs_and_Sc_Pub/intoPIX%20.... -- will this fit into the time budget or will it slow memory accesses? (They first say this is off the critical path but then that the marker is per-line, I don't see how both are true)

21 to 37 cycles is definitely lower latency than accessing memory. And you can easily pipeline it to match the rate of memory accesses.

> When the limited table is exhausted, a new key is chosen and all of memory must be updated (so you really don't want to do that) They dismiss this by again appealing to the rarity as "1-in-2^512" but if that's true you might as well just design the chip to blow up when the condition arises. If any timing information about "line appears in LUT" is visible to a program, then it is just 16 * 2^32 instead for an adversarial program (you can tweak line 1 until it needs a LUT entry, which takes just 2^32 writes; then repeat for the next line)

So an adversarial program can waste CPU? It can already do that.

But more importantly, the LUT only needs to be involved when checking the marker on a memory access. It should be very possible to make it fixed-timing.

Lying is as old as language. Monkeys lie to each other[0]. Lying using video isn't going to be fundamentally new.

Our ancestors have solved this problem for millions of years through context, trust and reputation systems and a bunch of other heuristics. We're in a historically unusual time where we've developed a medium of communication that's cheap to use and very expensive to fake. It's only the transition period back that's ripe for exploitation.

Deepfakes aren't that easy to make and they only do one specific thing and do it quiet poorly if your job is to actually fool people. The handful that I've seen in the news are obviously fake. This is not the general purpose video faking tool I think we're really talking about.

"The Great Filter" and the probability of alien "civilizations" or life in general are massively overstated because of a bias for imagining cool stuff. Existential threats are real, no need to bring extraterrestrials into the discussion.

You two are talking about different things. Frye is talking about warming the engine compartment; Epic is talking about warming the passenger space. You can warm the engine compartment more efficiently without idling by driving at low RPMs for the first few minutes; however, idling is as (or almost as) effective as low-speeding driving at warming the passenger area.
A to Z: Alphabet’s Cloud Software Contributions
Unlike most guides I've seen about ML, this one does a good job of focusing on developing and deploying a simple model first, then iterating. There are also lot of practical tips here, especially around feature engineering.

> the second phase of machine learning involves pulling in as many features as possible and combining them in intuitive ways. During this phase, all of the metrics should still be rising

As Google points out, after you build an initial model, the next step to increase accuracy is to perform feature engineering. They explain that this can be done manually or automatically using something like deep learning. Another option that people here might consider is using a library like Featuretools (https://github.com/featuretools/featuretools) for "automated feature engineering". Note: I am one of the developers.

Our goal is to help you increase the performance of your models without sacrificing the interoperability of your features. We have a post up about how our algorithm works here: https://www.featurelabs.com/blog/deep-feature-synthesis/. There are also plenty of real world demos on our website: https://www.featuretools.com/demos

More assertions that I just don't know that I buy. I don't ultimately think you have to take my assertions as valid counterpoints, but as things currently stand, I don't think either of us have actually presented any data. I'm just not asking anyone to believe that things are truly different than they used to be.

I've similarly been doing interviews for upwards of 20 years now. There are some particularly bad interviews I've done recently, but there were some particularly bad ones I did towards the beginning of my career, as well. Worse, some of the senior engineers I used to be under were quite bad, all told. (Which does not take away from many of the ones I was with that were bloody amazing.)

Which of those categories contains CanBuildFrom? It's #1, right? But instead of the number of characters typed, I think its primary value is in removing (from the call site) implementation details that the reader of the code need not be concerned with.

Its not going to be fixed until the cache participates in the roll back mechanism. After this you still have good old fashioned timing attacks but this can be fixed with a new set of instructions to ensure blocks of code take a minimum amount of time.

My personal opinion is that these are all terrible ideas. You’re attempting to normalize poverty. You can’t not live near jobs. You can’t not consume essential healthcare. This is not an argument about avocado toast.

I used to work for Champion Spark Plug 20 years ago. Chrysler asked us for price reductions every quarter. It got to the point where the engineer assigned to Chrysler hung up the phone one day and said "Fuck it. I'm just going to tell them to get bent because we're already selling them sparkplugs at a loss. What's the worst that could happen? We go out of business? They're already forcing that situation."

I'm certainly not saying that we have no redeeming factors. As you say, that would be an absurd mindset in this world we live in.

However, I don't know how you can deny that we are greedy and have limited ability for compassion. Do you deny Dunbar's number? If not the specific selection, the concept?

Do you deny that some men have 10 figures of wealth while others have nothing to their name?

Do you deny that we have, as a society, enacted a plague upon the planet, and are causing extinction of other species at a rate only witnessed within other extinction events?

Just because one has virtue does not mean one doesn't have vice, and certainly the same applies to the "one" that is human society. While we certainly have accomplished great feats and have seen great individuals, as a collective, we do not know how to relinquish the individual pleasures in order to facilitate comfort and health for all.

As the article I saw here recently that said something along the lines of "people are not stupid; life is just hard", your energies are limited, and there are those who take advantage of the splintered and uncoordinated thoughts of society to gain great wealth and power, and those who use their great wealth and power to splinter and confuse the thoughts of society.

That is the cancer, not my thought that these people exist; do not ignore that their existence is all but guaranteed by the very nature of the creature we must have been to find ourselves the dominant force of this planet.
Coding conversations: Transforming my career
I don't know if people or specifically children were happier in the 80s/90s, but after spending a couple of weeks with my 10-year-old niece, I'm completely floored at how she tries to fill every waking minute passively consuming content such as YouTube. It wouldn't be so bad if children were using the Internet to do something constructive or educational.

Of course, plenty of people from my generation spent their childhoods in front of the TV, but perhaps that was more easily regulated. (My parents, at least, wouldn't let me watch TV endlessly.)
I would consider something free if nobody had to pay anything for it.
When you rate you can indicate why you're giving the rating, but yeah that is what the rating is for. This guy wasn't threatening or aggressive towards us in any way, he was just an unpleasant and bad driver.

So we did what we thought we should: we gave him a rating that reflected our experience.

I did suggest that she complain about the driver's complaint since that was the real problem.. I'm not sure if she ultimately did though, as I left it up to her to decide what to do since it's her Uber account. :)

Browser extensions are subject to a permissions system, just like apps. Their code is also fully visible to you, and fully sandboxed.

The only real danger to extensions right now is that they can auto-update without a user review, and thus can "turn evil". It's happened to a handful of popular extensions (eg. Stylish).

Requiring the user to manually update extensions has its own share of problems though, so I'm not even sure if I disagree with browsers makers decision to auto-update.

But the claim that "all extensions are keyloggers" is just blatant nonsense.
I mean you say that now, but cab drivers can be pretty forceful. Some friends of mine had a dispute with cab driver, he took off with some still in the car, running red lights so they couldn't get out, and eventually stopped somewhere where they had other cab drivers meet him to get my friends to pay more money.

You might try to walk away, and end up with a cab driver chasing you down.
This feels like a Brexit dividend - no seriously hear me out - the normal conduct of government business is so snarled up with Brexit that almost nothing can get through - so despite lobbyists, it seems good ideas with clear benefits get through simply because government has to do something - and the simplest clearest actually obvious ideas are the only ones everyone can understand in the time acaikable
Without knowing how companies actually use my data, I can't put a price tag on it myself.

That means I can only rely on the price put out by the companies that collect it, and if they collude to keep prices low, it doesn't matter if they're caught, because they already have the data.

I also don't know the entire network that my data transits with the amount of money that gets paid for data -- Google could sell to some small company which sells to an international company, which sells to a shell company and ends the trail for most of us.

I suspect that internet and real celebrities will be paid orders of magnitude more for their data anyway.
Surprised there's been hardly any mention of Michael Pollan's new book. He's the author of The Omnivore's Dilemma and In Defense of Food, and most recently How to Change Your Mind -- mostly about the recent advances in the study and therapeutic uses of psychedelics. There's also an accessible chapter or two on the latest neurophysiology findings on the psychedelic or mystical state of consciousness.

The book goes into some detail about a few FDA-approved clinical trials for MDMA and LSD-assisted psychotherapy underway, some approaching Stage 3 -- these are mainly the result of over 15 years of work by MAPS[1] -- if Stage 2 results are anywhere near as successful as the small Stage 1 trials, we're pretty likely to see legal and widespread adoption for the treatment of PTSD, end-of-life anxiety, and/or depression.

> They weren't "poisoned" and it's just as bad in other places, sure. Now can we fix the damn problem already? Or do you just want to keep making excuses?

Oh yeah, just dig up all parts of the water supply that haven't been touched in 50 years, nationwide, and replace them.

In other words, can we fix the problem ? No. Aside from the cost, there's practical problems: we don't even know where half of it is, for one. Parts of it are under streets, bridges, buildings, etc ... They should be torn down

The problem was created by "our grandfaters" saving a buck and now the government "must" fix it.

Okay, but that's just the start. Next up, cleaning all riverwater nationwide of corrosive chemicals.

> It's a matter of principle, of morals.

It could be a matter of life and death, for all the good it'll do. It's impossible. If it was a matter of life and death, we'd be dead.

I was in a similar situation. I took a break from work and rediscovered the reasons I got into software. Then, I went back to work after a nice long break.

Don't just save money, invest it in an S&P 500 index fund.

Time is going to fly by and if, like me, you put money away each month, the interest will be a nice reward to yourself and give you new opportunities when you start to look for them.

James (Product Manager at GitLab) here. I've just picked up merge requests and have seen lots of feedback across multiple issues related to navigating between diffs/files when reviewing a merge request, and I want to make it better too.

There have been a few different solutions proposed including adding a file tree to the merge request interface, so you can quickly see a full list of the files and how they relate to each other. There is a design discovery issue for adding a file tree to the merge request interface https://gitlab.com/gitlab-org/gitlab-ce/issues/49189 scheduled for the next release to work out the UX in more detail.

Would a file tree make reviewing a merge request easier for you? Thanks for the feedback, and would love to hear more here, or on the issue.
Part of this difference is due to how departments are funded: math departments teach a lot of "service" courses for non-math majors. So there are enough TAships to fund most students who want them. Most other programs do not have enough TA positions to support all the students they have.

AT 25 I was going nowhere, having dropped out of my expensive liberal arts college education and the ample financial provisions of my parents (my grades were good too, I just lost interest in normal life paths). So I worked menial jobs, learned to want cheap stuff (I have never had health insurance, 36 years and counting) and no doubt I did display antisocial behavior and talked wild crap.

SO now I am almost sixty,and nothing else ever happened, MENIAL JOBS CONTINUED, the most I ever received as official hourly wages was $12.50 per.

I was amazingly happy every day until just past age 50, what brought me down was DEATHS OF THE LOVED ONES, I seriously don't expect to be happy again , much, for the rest of this lifetime. I had a good run at THE LIFE OF A FOOL, somebody has to do it.

As for advice to younger me, I never listened to advice. AND even when younger I knew that you can't serve two masters, and so I fully expected that my monotonous hijinks would have to be their own reward. CUE some Edith Piaf music, let me grab my coat and I am just slipping out the door.

Good luck and stuff.
Well, that the straw man could liquidate the asset, I assume.
There's a broader issue with the loss of discoverability. It's not exclusive to iOS, but the loss of the home button on the iPhone X and the replacement with gestures seems to mark a significant backwards step. Perhaps this is tolerable or even necessary given the increasing complexity of mobile user stories and maximal screen-to-body ratios, but it poses a lot of challenges.

Mobile is increasingly looking like desktop in terms of the gulf between "ordinary users" and "power users"; applications designed of one group are likely to be highly sub-optimal for the other, presenting developers with a difficult UX compromise. Most users understand the hamburger menu, which could be read as a sign of progress or a dismal failure.

I think it's something about remorse. Maintaining innocence when you know you're guilty shows a lack of remorse about what you've done. Admitting what you did and that you did it shows you at least know it's wrong and that you deserve some punishment.

Also those deals come with stipulations and caveats. Sometimes, turning evidence is done in exchange for lighter sentences. Being able to prosecute and jail a worse criminal in exchange for letting off a lesser one. Or there's reoffending clauses. Less jail time but if they reoffend in a certain period, they have to serve the full sentence.

Also, you say it should be about how long it would take to rehabilitate a person, that's different for every person. In a crime of passion, where someone accidentally kills someone else, should any jail time be given? It requires a certain set of circumstances. A set that may never be repeated again.
Well, if you actually read into the case, the screens that originally got him in trouble almost certainly were genuine parts that had "fallen off the back of the truck" or whatever excuse someone gave for trafficking in stolen components, and the guy's defense was "there's no way I could be infringing on their trademarks because the Apple logos are all inked over to make sure nobody sees them before I put them on the phones, and once they're installed you don't see them either!"

Which is not exactly the tale of plucky indie DIY repair hero people wanted it to be, and probably quite close to the "illegal importer trying to spin his way out of it" Apple accused him of being.
I had an evil idea once for a site where you got paid to supply information on other people. You create an account and narc on all your friends and family by telling the site what things they were interested in and what they have been talking about lately. The more money they make from targeted ads to that person, the more money you get paid :) Like I said, it is evil and no one should do it.
Can Fintech Solve the US Healthcare Crisis?
Right, could be a repeating pattern, but could also be a downward slope.
I actually have no idea if you're right or wrong.

However, one of my primary concerns regarding any "crowd-source" or direct-to-retail investment in startups is the information assymetry. It's tough, if not impossible (and certainly not scalable) for individual investors to do something like due diligence, especially in a manner consistent from startup to startup.

This is a potentially soluble problem, with adequate regulation, and/or with third party providers (although keeping incentives aligned might be tough), but, in the meantime, I fear it could attract businesses that are much higher risk than even VC-funded startups, if not outright scams.

On the other hand, I'm not convinced VCs have quite solved the problem, either, beyond, presumably, filtering out straightforward [1] scams. They do provide some minimum of risk-spreading by not investing in a single company (but their LPs get no say in those choices anyway).
