People romantically (har) think walls were there to keep the enemy out. It's actually to do the opposite, keep them in. They're chokepoints - takes a long time for even an organized body of people to cross an obstruction. But an unorganized horde? It's a death trap.

Hence the Roman engineering solution to this problem, the Roman roads. They could put a large organized army anywhere within their borders in an insane amount of time, camps always built on the march in the same exact configuration, with predictable roads and ditches. Though restructured to a point historians call fragile, Rome was still a bastion of engineering and organization. There was nowhere to run to and a price to pay.

In those days battles were always a matter of frustrating chase and escape. And once an engagement was forced, the Roman fighting style was terrifying and as equally organized as their infrastructure, nothing like a Hollywood confrontation with copied and pasted CGI fighters.

Lanes of soldiers in a checkerboard pattern called quincunx, timed by a whistle. Enemy faced a human chainsaw, basically. Imagine being their enemy, standing at the forefront of a ragged well-fed line with consistent kits and gear, each man carrying two spears, a sword and a shield.

Whistle blows, and the front line guys sprint at you full speed. At forty yards out they throw their light spear with a barbed tip and it gets stuck in your shield. Guy is still sprinting full speed at you. At ten yards out he throws the heavier spear and it too gets stuck in your shield. He shield slams you, hacks at you a few times unsuccessfully. You survived.

Then the whistle blows again.

Your shield feels noticeably heavier with two spears stuck in it. Guy turns around and runs back and there's another guy sprinting at you, about to throw a spear. You've just now realized first-hand how the Roman Imperial army fights.

Their money doesn't represent resources sitting idle. The whole point of the financial system is that there isn't $X trillion idle. The securities they own are claims on stuff other people are using. Talking about cycling it back into the economy is nonsense, because it isn't, can't be, taken out.

It's definitely rough... I've literally argued against both sides depending on some nitpicky points. I generally get the sentiment either way, I just disagree on the approach mostly because they tend to encroach on individual rights.

People have every privilege to be an asshole so long as they aren't infringing on another's rights. But they all seem to want to infringe on other's rights.

> Do you have the right to prioritize your personal activities over your employers protection of its' data?

It is absolutely fine in many countries to use a work computer for light and occasional personal use or on breaks. And no, employers don't always have the right to monitor all traffic that isn't relevant to the business, or even files on your machine marked as personal. Really depends on the local laws though.

Maybe not necessarily in 100% of the cases but once something is manufactured it is likely that the manufacturer will look to expand its customer base. Hence (imo) the militarization of police across the US and indeed the world.

Since pretty much everyone in this site (at least in the US) makes over $100k/year ... are you okay with not being able to work for a year and a half without pay?

edit:

Since you make over 100k, you're also considered a white-colar employee...

Your boss has decided the work-week is now 60-hours a week, and you don't get paid extra for it.

Oh, and if you don't perform, you're fired.

And if you try to work for a competitor, you will be sued and a protective injunction against you being able to work for the new job will be given.

And that's all a-ok by you, because you make what most would consider to be a wealthy lifestyle.

I loved the nQUIC paper. It's really sad that QUIC has not been thought of as a "meta" protocol of sorts, where you can bring your own crypto (or none at all). I find it kind of annoying that I can't use QUIC for intra-cluster communication with the crypto disabled, and leaving those preocupations for a service-mesh layer, or even just overlaying the entire cluster with a WireGuard VPN.

There are legitimate use cases for "running naked", but now we're doomed to jerry-rigging some BS ephemeral self-signed certificates in order to use any QUIC client that follows the official spec.

I think there is a misunderstanding. The App is used now by our workers in the wood warehouse to replace handwriting invoices. There is no online market place here. As a manager, if I want to know how the business does, I need to call the sales team at the warehouse and have a conversation for about 15 min, and I get no data to analyze. With this App, I am now getting near real-time info about the business without interrupting the workers and the sales team. The App is not for customers.
> Do you think Americans are using free speech well?

I think that's irrelevant, since being a free individual is the main reason being alive and healthy is desirable, not the other way around. If people just existed to keep an abstract group of people alive, with no person in that group actually mattering, actually being allowed to develop as the person they are, not the group they are in -- what's the point of having people at all? What would we be doing that insects or algae aren't already doing much better?

> Just because it's supposed to work that way doesn't mean it actually works that way.

Sure, but if it's not even supposed to work that way, or is even supposed to work the opposite, then that's still a lot worse.
The problem is you're missing an important aspect: members of the board of directors aren't employees.

Yeah, seems to me like the real problem is that people actually have a lot of doppelgangers, and applying facial recognition to the entire population, even if just as accurate as a real person is just not a useful thing to do.

Zoom is SO much more seamless than Meet. Its desktop clients exist, are usable, and don't force you to keep trying Chrome whenever something breaks. (I swear Google never tests their prodcuts on FF/Safari...)

Meet also has a very fixed layout. Its mic control bar on the bottom cuts off the names on the bottom row of participants. The UI on "waiting to connect" page is hilarious; it has a line of vertical dots for changing settings, and a line of horizontal dots for monitoring audio. There's a small concept in design called discoverability -- doesn't exist for Google, lol.
You Would Never Think Blockchain Is Used for This
This remembers me a bug I came across while developing a game for an <old game console here>.

Implementing a network feature, I had to poke a service server. But the OS DNS resolver returned broken results and sometimes hanged or crashed the system.

After a lot of head scratching and exchanges with the first party support, we found the issue to be a misread of the cache line of the CPU, delivering broken data to the OS and causing havok.

The problem was that as the cache line was 32 bytes, if the url being resolved was exactly 32 bytes long, it would trigger this edge case (probably the OS missing the ending null character).

The first party support said there was nothing they would do to solve this and suggested creating an DNS alias, but the domain was a third party address specific per project which in our case with our project codename was 32 bytes, they also were unwilling to modify or create aliases.

My solution was to add a dot in the address and this fixed it, as now the address was 33 bytes and the CPU fetched two cache lines. The first party technical support was surprised by the fix and called it "sneaky ;)"

Fun times.

I agree. It's incredible that the mismatches were only between 70-80%.

For comparison, I did another test where I took one of those youtube videos that shows you the same person's face over ten years. I used the original 12 year old boy as the image I'm using to match. Over 1,300+ images, it had > 70% confidence in all but 4 images (2 had big sunglasses, one the guy was in green-face, and the other one was actually his wife). And this is from a single picture that's ten years old.

Ask HN: Why shouldn’t we care about Dual_EC_DRBG, Intel ME and Crypto Ag?
Today, as proud Americans we face many real threats:

- Terrorism

- Russian hackers and communism

- Culture war breaking up our slowly-evolved perfect family model based on human nature (masculine and feminine traits) (who is against this? feminists)

- Intellecutal property theft by China

The US has superiority in technology (and has for a number of years) because we have the best people. We also have meritocratic immigration policies to bring in the brightest minds (no chain migration, no sir).

I read someone write recently: "but Intel can basically root into all computers"

I don't doubt this, and the NSA is in effect the password manager for the world, since they could have access to the world’s newest computers, so what? Somebody has to be that person, why not us?

You've posted this error here before, but there's an enormous amount of research demonstrating its falsehood. SOUPS is now in its 16th year (https://cups.cs.cmu.edu/soups/ has an overview of previous years) and has featured speakers and organizers including Ian Goldberg, Bill Cheswick, Ross Anderson, Adam Shostack, Ed Felten, Daniel Vogel, Chris Soghoian, Adrienne Porter Felt, David Wagner, Mary Ellen Zurko, Ben Laurie, and Lorrie Cranor. If you know anything about security and HCI, you know these people know a lot more than you do about them; they've been leading innovators in both fields for decades. Some of them have been publishing ways to reconcile usability and security since the mid-90s.

And they unanimously agree that you're full of shit.

In view of the state of research in the field, your statement is at the level of global-warming denialism or homeopathy, if not flat-earthism.

Do you know what a CLO is...?

Or maybe you were born in 2009?

FSB:

"Available data indicates that banks have the largest direct exposures to leveraged loans and CLOs. These exposures are concentrated among a limited number oflarge global banks and have a significant cross-border dimension.

... A number of non-bank investors are also exposed to leveraged loan and CLO markets. These include investment funds, insurance companies, pension funds, broker-dealers and holding companies.

... A comprehensive assessment of the system-wide implications of the exposures of financial institutions to leveraged loans and CLOs is challenging.

... These exposures are generally concentrated among a limited number of banks. These banks’ exposures to leveraged loans and CLOs, on a fully drawn basis, are significant relative to their capital adequacy ratios.

"Similar to other markets, the leveraged loan and CLO markets include direct and indirect forms of interconnectedness, both within and across borders. Direct interconnectedness arises from links in the intermediation chain, from origination and distribution of leveraged loans to securitisation by CLO manager.

... Through these direct links, shocks to the leveraged loan and CLO markets could transmit risks to financial intermediaries not directly exposed to such markets.

... Indirect interconnectedness can arise in the form of common exposures of banks and non-banks to leveraged loans and CLOs, and could provide an avenue for contagion among financial institutions."

Fed:

"Similarly, vulnerabilities stemming from leveraged lending were increasing through mid-February 2020, as demand remained strong while credit standards stayed weak. Issuance came to a halt at the end of February, as investors became more cautious and attentive to volatility in financial markets...

Defaults on leveraged loans ticked up in February and March and are likely to continue to increase, with the specific contour highly dependent on the path of overall economic activity. Such developments would weaken the balance sheets of lenders, including CLOs that hold leveraged loans, and amplify the economic effects of COVID-19."

This stat is clear evidence that there is not equality of opportunity.
That book is incredibly misleading.

This has nothing to do with machine learning. It is a simple correlational situation.

If African Americans have, on average, poorer credit ratings, then correlational models will begin to equate race with poor credit ratings, which will impact their ability to get credit and hence feeding back on that mechanism.

...of course RACE isn't allowed to be factored into financial applications, so the applications will often use other data points, like zip code, that end up having a correlation to bad credit as well as race. ...often producing the same result.

The problem isn't with the models - it's with reality.

The author famously said "Math is Racist". It's hard to get over such stupidity.
Boards don't actively do anything. They're a collection of notables whose presence provides clout to companies so they can attract investors, and whose inside connections to government and other power structures allows companies to curry favor and get special treatment. It's all politics and bullshit.
> The area they ruled (from England to Syria and Egypt) had never been under a unified rule before the Romans.

To be fair, you can say that about almost every empire - mongol, greek, british, ottoman, persian, babylonian, etc. I doubt the mongol empire stretching from vietnam to korea and moscow to baghdad will ever be unified under a single empire.

> If you consider how many different countries and cultures occupy that space today

To be fair, most of the countries and cultures that occupy that space today weren't ruled by the romans. Rome never ruled england as england came into existence after the anglo-saxons conquered roman britannia. As for syria and egypt, the romans never ruled the arabs who dominate the region.

> it really puts the magnitude of their empire into perspective.

Rather than the magnitude, I think the legacy of the roman empire is what separates it from others.

The roman empire wasn't particularly that large.

If you had accuracy similar to a human, and assuming this is an existing procedure humans do use, then of course it's useful -- you're doing the same task cheaper/faster.

It's a bit frustrating that a large portion of articles just refer to "police" as a singular group. This article is about the Memphis Police Department.

If a ring of doctors were caught illegally selling organs, we wouldn't title an article "Doctors have been selling organs for years". If bank tellers in a specific city were taking some money off the top of deposits, we wouldn't write "Bank tellers have been stealing money for years".

I'm sure there are some national issues with policing in the United States, but most police organizations are local. It's very unlikely that every local organization is bad, and even if they were, it would be very unlikely that every local organization is bad in quite the same way.

I don't think headlines like this help us balance the discourse. There's no concerted effort by police nationwide to spy on black reporters and activists. This is about a problem in Memphis, Tennessee. The content of the article doesn't imply anything beyond that. The title is extremely sensationalized, and many people will only read that far.
