I have some experience in developing IR/search software ( https://github.com/phaistos-networks/Trinity ) and, the way I see it, it all comes down to accepting the following premises:

- It’s all about the relevance models. Specifically, BM25 and TF-IDF which are widely used by e.g Lucene and variants just won’t do. Specifically, they only word for large enough documents anyway.

- Indexing and Search algorithms and practices haven’t changed much in decades (though some novel ideas have been introduced not long ago). Lucene’s index encoding is compact and facilitates fast access, but even compared to the one made available by Google which is arguable simpler in design, doesn’t result in more than around 5% reduction in index size and postings list access time (according to my measurements that is). Posting lists intersections, unions and other such operations implementations are pretty much common across IR systems as well, with little room for improvement.

To get great results, you need really great relevance models(1), a great query rewrite system(2), and, because query rewrites usually expand a query to include multiple disjunctions (OR terms and phrases), your search engine needs to be particularly efficient at handling those(3).

You also need to care for spelling suggestions and personalisation/content biases and factors, but those are secondary concerns.

> Comments started rolling in, but I had class until almost noon. With me in class and Cory at his day job, it was impossible to coordinate any responses until much later that day.

The quote above clearly shows a huge oversight -- there were no plans in place to block out time to do PR after the announcement. Better to schedule the announcement to coincide with a period when the co-founders would be able clarify the public's perception of the changes. Even for OSS projects, marketing is important. But that's not even the underlying issue.

There is a subtle but very important observation that the OP's article didn't touch and I think will help illuminate why the seemly small changes to Caddy lead to the outburst of entitlement and vitriol directed at Matt and Cory.

Humans are naturally loss averse[0] this is why there is an enormous difference between marketing copy that says "a $5 discount" versus saying "avoid a $5 surcharge". The original announcement[2] was framed[1] like a loss -- existing users should prepare to deal with previously non-existent advertising of Caddy's sponsors -- causing the human instinct of loss aversion to kick in in full force.

This will always happen whenever you switch your user/customer interaction from social to market norms [3] which is essentially what it means to monetize an OSS project. Better to keep a free product unchanged then create a separate product targeted at commercial users [4] to avoid alienating your free users, or incurring their wrath.

Engineers are generally skeptical of marketing but this is one of those situations when good marketing would have helped to put out fires.

$1B $2B $10B makes no difference. You can't.

Same as when Microsoft billions to "disrupt" Google in search with Bing. Fail.

If it was simply a matter of money then there are plenty of companies with alot more than $1B to spend on stealing FB's business.

When companies fail, as most do in the end, it is usually because not of external reasons but internal reasons - typically the company has grown too dogmatic in its own beliefs about its plac in the world which makes it ripe for disruption and replacement. This happened alot more in the early days of computing when the platforms were in flux - today the platforms are relatively stable which makes for long term stability of those companies that won the "winner takes all" battles.

There was a time, hard to believe now, where it looked very much like Microsoft woud own all computing for the foreseeable future. That didn't last long, and dogmatism and internal politics are to blame for that future not happening as anticipated.
I can unlock my phone with my fingerprints in the dark (example, at bed during the night). Do I have to turn on the light to use FaceID or do I have to type in a PIN instead? That would be progress /sarcasm.

I could also unlock my phone and my tablet with my face (don't remember how Sony and Samsung call that method) but it means that I have to point their cameras to me. Maybe it's me but their cameras tend to point to the ceiling when I'm holding them. Fingerprints are faster. Even the swipe pattern on the tablet is faster.

FaceID is probably more about the current impossibility of adding the fingerprint sensor to the bezelless and thin iPhone X. I expect Apple to solve that at the next iteration. FaceID would stay and be useful for some purposes, but people will be back at unlocking iPhones with their fingers.

A couple of these products function on unlicensed bands, which is what you'd need. The latency is very low and close to constant regardless of the length of the haul, which means that it could be difficult to tell that your packets even originated from a location other than your exit.

Not sure if anyone has documented doing this, seems like it would defeat the purpose for anyone with a practical need for it. Maybe I'll need to be the one to show it.

The hard part is probably tamper alarming the enclosure, the rest is just standard setup for the equipment and maybe some site security concerns. For example, considering what to do when the station goes down, since coming to fix it would be a good way to be discovered if your adversary is monitoring it.

Launch a service which takes the best from Fb & Messenger, Instagram & Snapchat (but without a "news" feed), launch a token, reward user activity and new user referals with tokens, generate enough hype and FOMO among key people that enough will start to see a real chance for network effects and thereby for gains in the token value.

A developer, if they so wish, can allow third-parties the use of their property in some use-cases that are beyond "critique or satire".

You need to build a new kind of social network. However, $1B won't help you much with that. You only need to build it and get 100,000 within a couple of months and 10x that number every year by becoming very popular because you have built something that people want. Money can only help you so much, it needs to grow by itself.
> If we open the pandora box of consent under 18, we will have to tread very carefully.

In my country age of consent is 14. There is no pandora's box, there is no widespread abuse of teen girls and children being raped. Only ones who routinely have sex and get pregnant at that age are gypsy girls and that's because their "traditions" require them to marry young.
I would say that part of the reason of FB popularity are the features that are addictive and disruptive. Same with IG. They design for addiction. The question then becomes if you do not design for addiction can you achieve success on the level of FB? If you are thinking in a social sense, then I would ask the question: how might we design an app that helps people connect, without being intrusive and letting people really connect?
How exactly does this analogy translate to unlocking a phone?
There is a bigger issue here: Why wasn't such an analysis done 50 years ago? Where is the incentive for people to uncover fraud?

Like much of the infrastructure in the real world, the sad fact of cybersecurity is that in many cases, attacks aren't known merely because someone semi-informed has not committed much effort to getting in, or more likely, has not yet triggered an event that would publicize their intrusion.

sillysaurus may be overgeneralizing a bit but he is correct about the vast majority of companies. To me, the key differentiator between companies with serious security projects v. companies with me-too, mantlepiece-style security projects is active, engaged technical leadership at the very top.

This is not to defend Equifax as much as it's to desecrate the widespread dogma of the managerial class that an MBA qualifies a person to lead any project. Time after time after time, most of us who've worked in corporate America have seen security pushed to the bottom of the stack, only becoming a consideration for about 18 months after the last close call or underpublicized breach. There is virtually no appreciation for the problem itself at high levels, or the complexity involved in reasonably subjugating it.

CISO is something of a nightmare job because you're essentially the company's designated patsy/lightning rod. Most of the time, CISOs and those in analogous roles get stuck with the blame for the company's security without ever really being given the authority to do anything about it.

I knew a CISO who set up camp, including prop tent, outside of the CIO's office until he finally agreed to get his guys to patch a server. The CISO took a picture of himself doing so, because he knows the game; if the intrusion occurred, he would have apparent visual proof that would allow him to deflect blame onto the CIO.

Reckless disregard like this is absolutely common and routine, and if you have any doubt about that, a cursory inspection of the sites of companies that are not tech pioneers will easily disabuse you of any contrary notion. Equifax is not alone here, not by a long shot. Not even among large companies dealing with sensitive financial data (don't ask how I know).

The only reason we haven't seen (or, more likely, haven't learned about) widespread cyber-intrusion-apocalypse is because semi-competent people just have other things to do, and there is substantial legal risk if caught. I fully believe that 95% of America's biggest companies have systems that are easily penetrable.

Again, let me reiterate that this is not making an excuse for Equifax. It's just acknowledging that the problem supersedes this single instance. We need a revolution in system admin and application security before we'll solve these issues, because the plain fact is that companies simply can't be trusted to do it under the current conditions.

> "From the POV of a free software true believer (Hello there!) there is no point to Open Source."

The key differentiator between open source and free software is ideological. If you value ideology over pragmatism, then I'd see your point, otherwise it's kind of a misguided statement.

There's nothing in the ideals of free software that prevents what the Caddy authors have done. Stallman has made it clear time and time again that the 'free' in free software is a matter of liberty rather than price. The freedom to charge money for free software has been made very clear to anyone paying attention. Here's an article from the GNU Project website about selling free software:

I'm not saying this is true of Face ID but if you set a pin, and there is also a much less secure way to unlock the phone, then yeah the pin was pointless because attackers will just go through the path of least resistance.

Said another way, the chain is only as strong as its weakest link.

Make double digits billions, and dump the majority of the proceeds into creating the most advanced research institute humanity has ever seen.

No research papers, and thus no publishing to journals. Lots of basic research and epistemic hygiene. Emphasis on understanding core mechanics of things from the ground up. Clinical trials used only as mere regulatory formalities, not as crutches to throw things at the wall and see what sticks.

Secondary goal is to bring about the creation and large-scale deployment of robotic infantry to fix the security and human rights situation in some of the world's poorest countries. The technology to do that has already existed for some time.

Beyond that I'd really love to write and direct an HBO series based on X-COM. Bringing back a ton of 90s games with AAA production values would be really fulfilling as well. Recapturing the magic of SimCity 2000 with modern technology is to me what dreams are made of.

That's a claim I have never heard before and I don't agree with. You have some kind of argument to support that drive-by claim? Since there are no fully autonomous SDCs yet you'd have to explain away any existing autonomous robots.
I couldn't agree more. I've long said that it's insane that the law can say that someone is not mature enough to consent to sex, but is mature enough to commit statutory rape. The idea that two teenagers of say 14 and 15 who consensually go with their natural urges can then be both put on a sex offenders register that will affect them negatively for the rest of their lives is absolutely insane and proof of a fundamentally broken system.

Build something that's got most of the well-known features of Facebook, plus/minus whatever you feel like you need to change with regard to privacy, business model, decentralization, etc. You can do all of this for much, much less than $1B. The only thing you're missing is two billion users.

Use the remaining funds to stir up sensational controversies that make people wary of Facebook, lobby governments around the world to harass Facebook, and offer monetary awards to get influential groups of people (e.g. schools) to switch to your platform. Once you've got a bit of momentum, spend the last few million dollars to hire a bunch of shady guys to take out Facebook's leadership and infrastructure -- either physically, with bombs and guns, or virtually, with very powerful malware. By the time they recover (if ever), you're the one who has two billion users.

This is how you destroy a company when you're actually intending to do so.

For the rest of us who don't want to get our hands dirty with guns and viruses, I suspect that $1B and the lofty goal of disrupting Facebook are actually going to get in the way. Facebook won't be disrupted by something that's trying too hard to disrupt them. Zuckerberg will see the competition coming from a mile away and respond with $2B, $3B, or more.

The key is to come up with something that's so completely different from Facebook that they'll have a hard time even seeing you as legitimate competition. You fly under their radar, make no headlines, and refrain from making ambitious statements like "I want to disrupt Facebook" until you've created a whole new market and they can't pivot to compete with you.

The reason the illegal solution above works is because Zuckerberg doesn't expect to be assassinated on his morning jog. Do something that's just as unexpected, only legally this time.

Infosec guy here.

I don't believe those systems are necessarily any more secure than Equifax's. It may be that Equifax got breached first. But it's also partially because it's actually incredibly difficult to steal funds from traditional financial institutions. Not because of technical security measures. But because of procedure and regulations.

As an example, money illegitimately moved from bank A to bank B can (and in most cases must) be reversed. Even if done digitally.

Usually you store the text anyway, so you can select and search it, or have it read by accessibility tools.

From what I remember, the clean, non-customizable interface was one of the main reasons FB surplanted MySpace for a lot of people.

One thing I learned from designing websites is that no one goes to your site for it's artistic design. If your site looks great then it won't hurt. But, if the design gets in the way of accessing the information they're there to find, people will hate it.

MySpace was a perfect example of this, from what I recall.

That implies we have hit or at least know the exact capacity ceiling for, in particular, recurrent/dynamic networks (I do agree that with static networks it seems more clear cut). While it will not be general AI, I'd assume, things like the neutral Turing machine, pointer networks, and many other open research areas leave room to speculate that we have not yet "found" that ceiling.

1. You've never used the device so making statements like "this is much slower" is pointless conjecture.

2. FaceID is completely different to the Nexus which is based solely on 2D image recognition and is easily able to be forged and doesn't work in low light conditions.

3. From what Craig said in the Daring Fireball interview it will actually be much faster than TouchID since the authentication apparently happens in parallel to the unlock operation.

Immediately? No real company can do this. 1-2 weeks after the announcement is the best you'll see, even with something of the magnitude and publicity of Heartbleed. I'm not saying that's how it should be but that's how it is. Most organisation's it's quarterly!

All of these can be designed into a system and still maintain 100% uptime

Sure. If you were designing from a clean slate right now. The vast majority of organisations in the world aren't.

And believe me: in 10 or 20 years your new design would have revealed flaws too, and look laughably primitive to the practitioners of the day.

What's the solution then? An architecture in which no single compromise can compromise the entire system. That's getting harder and harder to do as the landscape homogenises around Lintel.
