Submission + - Measuring the Impact of Early-2025 AI on Experienced Open-Source Developer Produ (metr.org)

Comment Hmm - is this really like TCP (Score 3, Interesting) 133

From the article:

.. feedback loop allows TCP [to run][ congestion avoidance: If acks return at a slower rate than the data was sent out, that indicates that there is little bandwidth available, and the source throttles...

which does seem to be a far cry from TCP. While common lore (and the modern buffer bloated internet) has it that high RTT means little available bandwidth (and it sure does play havoc with the bandwidth product - giving rise to that lore fairly) - the design calls for packet drop rather than delay to indicate a link being overloaded. And while the source slows down - it does not actually throttles; it just awaits the ack - it wont slow down the next packets. It is just that the window won't grow further. So makes one think of the observations in RFC-2488.

And there is also the expectation of "But the IETF document still plays a subordinate role to that source code.'' in the original article. However one interesting expectation or requirement of IETF standards is that one expects at least one, ideally two, independent implementations based on the written spec. This would alleviate the concerns that the VP8 case is too leading - as one has now an example of an independently derived code base - which has taken the written spec as its lead - and secondly it would also give the community a very fair idea as to any residual IPR issues, by Google or by others. Thanks, Dw.

"There are times when discussing a situation on the radio to a supervisor is not acceptable because of the questions relating to which charges should be filled or what city ordinances may relate to a certain situation."

And those are NOT appropriate for the radio why? That is what a unit-to-unit call is for: rather than the whole talk group hearing it, only the supervisor and the cop here it. AND you get it on the nice multi-track recorder, admissible in court, in case any issues arise.

"I know for fact that every department going doesn't use APCO-25..."

And those departments are upgrading as DHS money becomes available. Moreover, I'm pretty sure California is on APCO-25, since they are buying the equipment to test it, and are testing their radios on that equipment.

"You loose[sic] credibility with me when you make remarks that the police abuse people."
And you "loose" credibility when you assert they don't. I'm not saying ALL cops abuse people, but SOME do - this is a demonstrated and adjudicated fact - and many times they use the cell rather than the radio precisely due to that nice multi-track recorder on the comm center.

The cop has to carry his radio - that's a given. There is no reason for him to have a state paid-for cell phone. Even if he needs to make a phone call pursuant to his duty - again, he can make a PSTN interconnect call on the radio (and again, have the advantage that it is recorded in a nice court admissible format).

Sorry if I touched a nerve, but: it is exactly that mentality - "We are the Thin Blue Line, we must protect our own, no matter what" that is causing people to NOT trust the cops. Rather than saying "Use the radio. Be recorded. If you are doing nothing wrong, you have nothing to fear. If you ARE doing something wrong, IA will find you and destroy you, and we will all help, because enforcing the LAW is our JOB." you have folks like you saying "It's OK if we hide things, because, well, BECAUSE, citizen."

Considering that I DESIGN the equipment the law enforcement types use to check out the system, I suspect I know quite a bit more about APCO-25, the uses of it within various law enforcement contexts, and the infrastructure than you do, sir. I doubt you could tell an LDU1/LDU2 from a TERMLC or a PDU, or even know what those acronyms are. I seriously doubt you have ever worked with any LEO comms officers, where I was working with the Phoenix/Mesa project on the first deployment of APCO-25 there a decade ago. I've worked with the FBI, the Secret Service, and several state level LEOs.

Again: there is NOTHING a LEO needs to discuss officially that cannot go over the radio, and be more secure than going over the PSTN, let alone any cellular networks.

"Come to think of it there are a lot of state LEOs that carry cellphones so they can discuss matters not suitable for regular 2-way radio...."

And that is bullshit. Most states are now on APCO-25, which supports encryption up to AES-256 (it also supports encryption beyond that, if you get the appropriate crypto modules from No Such Agency). The only reason anybody would use a non-secure cellphone vs a secure radio is that the secure radio is recorded at the dispatch center, making it somewhat difficult to discuss how best to "accidentally" allow the suspect to fall on his face, repeatedly.

This kind of thing always makes me wonder why you see so many homeless people. They could just smash someone's head in with a rock and have a nice, clean, warm home with three squares a day and plenty of time to read or watch TV.

Methinks you play The Sims too much - or is the homeless person who's clunked me on the head not going to have to explain himself to my friends who find him in my home and me nowhere to be found?

Or are you implying that prison is better than homelessness? That the threat of larger, nastier people, who might seek to stick a shank (or worse) into you for fun, that the loss of freedom, is better than homelessness? Perhaps it is not a lack of being a sociopath but rather the simple calculation that even a sociopath can make - that freedom is better than imprisonment.

Comment Re:Alternative ways to develop? (Score 1) 262

The issue is developing the negatives. In chemical photography, you don't just expose a piece of film to light and poof! it's a negative. You have to expose the film to light briefly, then keep it in the dark. Then you have to run it through a series of chemical baths that take the molecules of the film that were altered by the light, and "fix" them so they won't be altered by light anymore, while removing the molecules that were NOT altered because no light hit them, to grossly simplify the process. (even Polaroid film does this, it is just that the chemicals are embedded in a capsule on the film, and that capsule is broken when the film is removed from the camera, causing it to bathe the film).

Certain films require different chemicals, in different sequences. The chemicals and sequences for Kodachrome film are different than for Velvia, or other films, and for Kodachrome, are much more complicated (more chemicals, more steps, with very tight control over the time the film is in the chemicals, the strength of the chemicals, the temperature, etc.) That is why, as color films with simpler processes became available, fewer and fewer shops wanted to keep all the gear to process Kodachrome around, until there was only the shop in Parson left.

So you might be able to scan a developed Kodachrome negative on a good film scanner, pull it into your computer, and do "stuff" with it, but you still have to get the film developed first.
