Pessoa is one of my favorite poets. I would not describe most of his works as truly remarkable, but his best works are up there with the angels and the astronauts. My favorite poem of all time: Autopsychography The poet is a faker, Who’s so

Telecom act of 1996 paid them to build fiber but they set the speed limits low enough that they could satisfy it with DSL. There’s new DSL tech that’s ~100mbps, so this is that technique again. The fatal flaw in 1996, like today, is not pus

This. I am insanely embarrassed by the third world telecom infrastructure many Americans have to live with. 100Mbps symmetrical is just on the edge of what telcos can jam into dsl over their existing install base. The goal of the telco is t

Yeah VoLTE and VoWiFi were just getting rolled out when I left telecom. It was all IMS and hacks on top of SS7 and stuff like that. WhatsApp really applied a ton of pressure to telcos and changed the game. Do you remember they an internatio

Cinderella ends happily ever after and the New Testament doesn’t. I think it’s that simple.

Ok so like… think about telcos vs say, whatsapp. WhatsApp is sip, it uses srtp, the whole 9 yards. It works way better than telcos… BUT!!! It rides over telco rails. This is the dirty truth. What we think of as telco is evolving. Telco is d

Celsius told their customers they were accruing Bitcoin and then Celsius didn’t buy the Bitcoin to deposit into their accounts, instead using the money to buy their CEL token that their ceo was dumping on exchange. Their business model was

Man, not putting Fully Qualified Domain Names in code has been such a recurring source of pain in my software life. You make so many assumptions about the way people parse domain names and all of them are wrong. Vendors do all kinds of thin

I would say that it really depends on how you think about "the system." If the hardware is in-scope for the system, you're generally out of luck at having provable guarantees unless you're willing to operate a foundry an

I mean, I think this really depends on how you define ethereum. I think we all agree that there hasn’t been an effective attack against the consensus mechanism in a while (we could argue the original dao was sort of a successful attack agai

Cryptography has mathematical proofs of the underlying math that are rigorous. There are constraints such as breaking if a proof of an attack against the discrete log were to emerge or other constraints related to p=np. The implementations

We use this internally at mobilecoin as the base framework for new PRDs. Very clarifying.

3AC isn’t just large. 3AC is the largest trader by volume in the world for like 4 years. Them going bankrupt is like long term capital management going bankrupt.

The answer, as always, is that speculative execution is the devil. I’m not convinced you can write a “for” loop safely on a modern processor.

Does this also include the whole buying toxic assets thing? Not sure where that fits in your 3 options, but it’s definitely something they’ve been doing, to the tune of trillions of dollars.

We all owe djb a great deal of gratitude for this hard-won freedom. This is one of the greatest victories in hacker history. I hope to never see this stricken from the law of the land. Code is speech.

I cannot state how real this is as a startup. There are instances where I have said “yeah I totally agree with you but our lawyers worded it this way.” Most of the time it’s fine and not material. Some of the time it’s the defining detail o

Here’s how I feel about this: You can write all of the tests, you can get all of the audits, but there’s nothing that’s going to stop a 13-year old polish kid from mucking about in the guts of your tech. Security isn’t a promise you can mak

Yeah mobilecoin makes heavy use of SGX. For what it’s worth Intel isn’t going to deprecate this server side for modern use cases anytime soon. The trade offs between zk and hardware accelerated encryption still lean towards hardware though

As someone employing a lot of engineers right now, one of the problems is that engineering will just keep requesting resources ad infinitum if there’s no budgetary limit. The constraints of the business are actually always financial, and wi

Honestly, my guess is that the fab production issues impact everyone. I wonder if they get the same number of runs per $ as they used to pre-covid, my guess would be no. If that’s the case, that drives BoM up and Apple is hyper margin consc

The pace at which apple is pumping out new silicon is astounding. It’s hard to imagine anyone competing with them pound for pound, especially in the flops per watt game. I still can’t get over the fanless MacBook pros and the battery life.

If you spent 2 years somewhere and can’t find a single person to even confirm that you worked the position you’re asserting, something’s wrong.

Came here to say this. As far as I’m concerned this is a privacy protection. It’s trivial to verify someone’s position at Apple with a reference check.

Is this only effective at small scale? Many of the biggest hedge funds in the world that do high frequency make money by effectively front-running the book. If you are executing these trades across exchanges I don't see how you don&#x2

Lightform is sick. I wish they'd open source everything instead of (I assume) selling all IP to a patent troll to recoup sunk costs. If I were a VC, I would make it a covenant in any seed investment that the company had to open-source

I often wonder what the world would be like if apple had gone through with it (I am definitely not advocating for it, but wondering what the trade offs would be on the other side of the rollout). Specifically, I wonder if we would’ve gotten
