My email is eritead@dashborg.com. I'm based in London and interested in discussions related to web development. I wrote a book about delay insensitive circuit design whose landing page is at https://www.delayinsensitive.com. I've been teaching myself Go and AWS lately. My github is https://github.com/gueststar.

gradschool··on NYC Congestion Pricing Tracker
Your points are well taken. I wasn't aware of the Guardian poll and I stand corrected about my implication that the charge lacks public support. With regard to the moral issue, I have less of a problem with tickets that are paying for something like running a train, or for that matter a bridge toll paying off the bonds that enabled the bridge to be built. I have more of a problem with someone demanding money for nothing. I haven't heard it claimed even by its supporters that road maintenance depends on the congestion charge. To my knowledge the main justification has always been that the charge funds the payer's behavior modification. Is it for the payer's own good? Is it for the greater good? You may well differ, but something about that doesn't sit right with me however noble, especially when it pertains to law abiding citizens acting within their rights.
gradschool··on NYC Congestion Pricing Tracker
Congestion charging started in London in 2003. I'm skeptical about the justification that it's intended to disincentivize unnecessary driving because people who drive frequently get a bulk discount rather than a surcharge as one might expect if that were the actual intention. A bulk discount is more indicative of a policy intended to maximize revenue. I'm also skeptical about the justification that it's intended to reduce pollution because the discount for electric cars is ending this year. I have a moral issue with it as well because the roads are financed by everyone's taxes. Around the time the charge was starting it was easy to find supporters for it on tv chat shows but I never met one in real life. I assume there are some but that they support it in a naive attempt to keep anyone poorer than them off the road. Otherwise, the supporter's problem of too much congestion would be easily solved by not driving. The charge has tripled since its introduction so maybe there's an element of poetic justice in it for some of them.

gradschool··on Ask HN: Do you backup your Emails?
I use mpop with a local mailbox file ~/Mail/inbox and mutt as the mua (so no fancy archive hierarchy), cleared annually and copied to a file named like ~/Mail/inbox.2024, searchable with grep, backed up remotely in encrypted tar files on backblaze with passwords committed to memory, locally on a zfs file server, and annually on dvd for at least a decade in case all my hardware gets fried.
gradschool··on Ask HN: Facebook is bullying me, what can I do? Warning
Can confirm. You don't need a lawyer just to write an official sounding letter. Patio11 (Patrick Mackenzie?) has a blog post somewhere about how to write one. In short, avoid emotional or threatening language, write like it's nothing personal, use words like "require" rather than "demand", set a deadline for a reply, and don't say what happens if it's not met. That should scare anybody who reads it into sending it up the chain. Regardless of that, your audience is not just the recipient but the judge to whom you'll show the letter to prove you did everything you could to resolve the matter before going to court.

I used this technique to good effect in what would have been a clear case of tortious interference because of someone posting false and misleading information about a business. IANAL but I'm not convinced facebook has done anything illegal to the OP.

gradschool··on The Soul of an Old Machine: Revisiting the Timeless von Neumann Architecture
I don't like to rain on anyone's parade, but this is at least the third time I've seen one of these comments, and if it were me I'd want someone to point out a drawback that these young whippersnappers might be too respectful to mention. Isn't it a truism in modern computer architecture that computation is cheap whereas communication is expensive? That "fancy routing hardware" is what mitigates this problem as far as possible by enabling signals to propagate between units in the same clock domain within a single clock period. Your system makes the problem worse by requiring a number of clock periods at best directly proportional to their physical separation, and worse depending on the layout. If I were trying to answer this criticism, I'd start by looking up systolic arrays (another great idea that never went anywhere) and finding out what applications were suited to them if any.
gradschool··on Flexible RISC-V Processor: Could Cost Less Than a Dollar
Any ideas on why they'd use NMOS [1] instead of CMOS if they're aiming for low power? Too many layers? My (amateur, outdated, and probably wrong) recollection is that CMOS dissipates very little power except when switching, but not so for NMOS.

gradschool··on The first nuclear clock will test if fundamental constants change
The version of that story I remember is that John Wheeler said to Feynman that the reason all electrons are alike is that there's only one electron, which we perceive as a positron when it's going backwards in time. Feynman instantly refuted the idea by pointing out that there are more electrons than positrons.
gradschool··on Authenticated Boot and Disk Encryption on Linux (2021)
I don't trust bios passwords. There's probably some jumper on the board that bypasses them or a previously planted hardware keylogger. I always boot off separately stored immutable rescue media whenever the machine has been out of my custody and checksum the whole boot device. Your move.
gradschool··on Man Arrested for Creating Child Porn Using AI
> Do prosecutors now need to find and identify depicted victims to prove a CSAM charge?

Surely that would be a good thing if it incentivizes prosecutors to track down the purveyors and distributors instead of just stopping with easily targeted consumers. With nothing to establish beyond mere possession, by some metrics their performance is optimized to the contrary, much like the war on drugs.

> Does believing material was AI generated serve as a defense?

Believing that stolen property was legitimately acquired is a defense against a charge of possession of stolen property, as is plausibly claiming to have been set up. The alternative enables anyone with physical access to cause anyone else to be guilty of a crime, surely a net negative for society.

> We already have severe limitations on fictional depictions of this type of content so prosecuting AI depictions isn't anything particularly new.

Are you advocating its expansion to a general principle? Maybe Agatha Christie should have faced charges for the crimes committed by her characters.

gradschool··on King John's Lost Treasure
King John's treasure is still very much a part of the cultural landscape in Norfolk. Anyone digging a hole for gardening or construction purposes runs the risk of some smartass coming along and asking whether he has found King John's treasure yet.

I saw a documentary some time ago that I can't find any more about some guys who raised money to look for King John's treasure with ground penetrating radar. They were unsuccessful but with more money and more recent technology there might be a startup opportunity in there somewhere. On the other hand, I can't imagine they'd be allowed to keep it.

gradschool··on Ask HN: Roast my startup landing page
I don't like to be negative, but since you asked for a roast, I'm seeing mostly big stretches of empty space with intermittent blurbs of text that reads like the filler text a wordpress theme example page. Toolbar menu options are unresponsive except for one that brings up a noscript dialogue for me. Don't you know that web sites should be readable with javascript disabled?
gradschool··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
Are those arguing for immortality assuming that aside from physical decline we improve monotonically with age? That's not at all clear to me. For example, the general consensus among linguists is that the ability to acquire native fluency in a language is lost after a certain age. Could there be other less obvious deficits in neuroplasticity that people striving for immortality would need to address? Sticking with the same example, how do we know it doesn't confer some evolutionary advantage to repurpose the language acquisition firmware (whatever that may be) to more age appropriate ends later? Oddly enough, a couple of star trek episodes I'm too lazy to look up got me thinking about all this. In one of them, captain Picard gets a chance to relive a regrettable incident from his youth and ends up ruining his life, and in the other, captain Janeway goes back in time to help her younger self and finds out they both have something to learn from each other. Relatedly, someone asked William Shatner what he wished he knew when he was younger and he said a better question would be about what he's glad he didn't know. Disclaimer: I had an unexpected sudden cancer scare last week so maybe you should discount my comment as a rationalization.

I did a search on an obscure topic I like and got impressively well informed results, so hats off to you. If this isn't an awkward question, how does one avoid running afoul of Google's rules against crawling when implementing a service like this? If someone were to post a link to a report obtained through your service on a blog or something, would that be a good thing in your view or more like piracy?

gradschool··on A New Kind Of Dance Science (combinatorics of social dancing)
Choreology is an established discipline. There's no reason to re-invent it without improving on it. Some people might do it professionally. A big budget musical production typically will employ a choreologist to make notes during the rehearsals. Members of the company can ask for reminders about their parts, which the choreologist not only will have written down but will be a good enough dancer to demonstrate.

> Stay away from Manjaro and Pop as they have a history of breaking packages

Further to that, if you intend to use valgrind as part of your development workflow, note that valgrind sometimes stops working on Manjaro and languishes that way for months. For complicated but ultimately boring reasons that you can research for yourself, the issue isn't resolved by reverting to a previously working valgrind package. I was on the verge of switching from Manjaro to Arch for that reason but lately it started working again so I'm giving it a reprieve. If I were starting fresh I'd use Arch.

gradschool··on New Aztec Codices Discovered: The Codices of San Andrés Tetepilco
I think it continues to happen in forms we don't easily recognize because of our biases. When Google tried to scan every book in existence, the copyright lobby put a stop to it because of "intellectual property rights". Nobody's claiming that Sci-hub is sacreligious, but it's on our cultural gatekeepers' hitlist all the same. I suspect that future generations will view these events in the same light as the destruction of the Mayan codices or the library of Alexandria.

Some details about cooling these devices would have been informative in either the article or the white paper.

What breakthrough is going to enable a closely stacked ensemble of them to perform acceptably without overheating?
gradschool··on Systemd by Example (2021)
I wish I could make friends with systemd like y'all. I spent at least a week wrestling unsuccessfully with systemd (admittedly starting from complete ignorance) to make a service that synchronizes a local directory on a laptop with a remote directory on a server after a docker container is stopped but before the filesystems and network stack are torn down during poweroff. It was easy enough to accomplish by manually invoking a script prior to powering off but no amount of cajoling, poring over documentation, or reading and adapting examples from forum posts on my part would get systemd to do it automatically without conflicts, race conditions, or timeouts. Is this not exactly the kind of problem systemd dependences are intended to solve?
