Читаю:
Золотые слова, только господин глава фракции, ключевой вопрос: ЧЬИХ денег?
Если тех лиц, кто с вами говорили, то они понимают деньги только на одних условиях - когда главные хозяева они и все решения принимают они.
А если государственных - то это прямой путь на турма сидеть.
В одной большой недружественной стране давно поняли, что правильная схема такая: ФРС деньги печатает, системообразующие банки их берут, в крупные пенсионные фонды передают, а те покупают новые компании с такими мультами, что глаза на лоб, за три века не окупятся, и когда эти компании потом скисают и исчезают - за это никого не наказывают, вот это школа предпринимательства!
И то, там в последние года фейк ит тил ю мейк ит как-то странно понимать стали - то Лизаньку на турма сидеть пошлют, то SBF возьмут и под суд отдадут. Если это превратится в систему, то и у них со стартапами плохо станет.
Учиться предпринимательству без денег – всё равно, что заниматься плаванием в пустом бассейне.https://t.me/nechaev_official/278

Re: Brute.Fail: Watch brute force attacks fail in real...
So funny story, for a while I worked on a 'reverse' exploit. Which is to say morphing the response from ssh to the client with large malformed packets. The idea was to crash the client making the request. In my case I found these attacks would have like 6 to 10 attempts from the same source address. By time stamping the requests, I could evaluate if the next attack from the same address came more quickly or more slowly. I then had my server "morph" the return payload somewhat randomly and keep the three responses that caused the most slowdown. When I got to 100 variants that had "won" this selection criteria I took the three best and started over from there. After a couple of months of this I finally got a response where after one request I would not get a second.
I felt extremely pleased with myself for about another month, and then my server address got hit with a massive DDOS attack (for me anyway) over my 6MBPS DSL line. So clearly I had hit a nerve somewhere :-). Anyway, I moved my server to a different address and used fail2ban to just note source IPs and put them into the IP tables as banned addresses. That works great and hasn't resulted in the same sort of drama as last time.

Предложение РДК встретиться губернатору Гладкову в церкви и без оружия – отсылка к знаменитой встречи шотландского короля Роберта Брюса с графом Джоном Комином.
В 1306 году, время Второго шотландского междуцарствия, в ходе которого бароны сражались против Роберта Брюса, Брюс предложил Комину встретиться в церкви Грейфрайарс в г. Дамфрисе безоружными, чтобы там перед святым распятием не лгать друг другу и не пытаться друг друга убить. И, конечно, убил Комина, а еще и его дядю, также пришедшего на эту встречу.

Re: High prices make textbook ‘piracy’ acceptable to m...
I came to America poor, and went straight to a public university, on scholarship and no money to even pay for food (grad seminars and special events with free sandwiches and pizza is how I learned about things like quaternions as an undergrad). But as an eastern European hacker, i had a complete disregard of copyright, I also grew up in the 90s when hacker ethos included strong anti-authoritarian elements. No way I was going to pay those ridiculous book prices.
So first thing I did was setup a DC server (direct connect, early 2000s p2p sharing protocol) with a friendly grad student on university infrastructure, where we shared books, encouraged other students to upload books, we also built a dyi book scanner (there's one popular design that comes up first on google). the bookscanner at some point had a near 24/7 utilization, and people were coordinating time slots by dc messages. the room with the scanner (which is also where the DC server was) turned into a kind of unix room/hackerspace, because there was always somebody there working on something only vaguely related to university courses as such.
reminiscing on things like that always makes me realize just how much hacker culture has changed, to a significant extent as a result of societal pressure. I was extremely lucky, because when the handful of us got inevitably discovered, what followed was a series of meetings with department dean and university heads, lots of stern talking, which basically ended after they were convinced that they put sufficient fear of god in us. I'm particularly grateful to one networking and os professor who showed up to every single one of those meetings to advocate on our behalf. said professor had a significant contribution to computing in general, was strong supporter of old school hacker ethos, and is just all around great guy.
only a few years later aaronsw was thrown to the wolves by the cowards and bureaucrats (but I repeat myself) at MIT over his JSTOR downloads, which in my personal perception of history was the end of this kind of "oh captain my captain" university hacker culture.

The satire in the title is reminiscent of how Firebase was born.
We were previously working on a chat system called Envolve (https://www.envolve.com), that was 'Facebook Chat for any website'. A game that was using us for in-game chat created channels, used display: none on them, and passed game state through the chat.
We scratched our head, asked them why, and learned they wanted to focus on the frontend, not to deal with realtime message passing.
This led us to create a 'headless version' of our chat infra (re-written in Scala) that became the Firebase Realtime Database.

It’s so much worse than you think.
Many textbooks come with license keys specifically so you can’t buy used books anymore.
Students who do buy a used book are typically coerced into buying the license key to do digital homework, or whatever other reason.
When I was teaching during a graduate fellowship I accepted paper assignments for students who bought used books, or who shared books with other students. The Pearson representative complained and I was given a talking to by the graduate student dean about consistency or some such nonsense. Eventually I would be reassigned to teach classes that didn’t involve digital components.
We called it the textbook industrial complex.

Считаю, что это гениальный документ. Памятник эпохи!
Во-первых, азербайджанское лобби в Сомольном, судя по всему, расставило своих людей вообще везде, в том числе на вычитке текстов.
И стало значительно лучше.
Только вдумайтесь сколько слоев смысла в формулировке «Совет по улучшению качества жизни при губернаторе Санкт-Петербурга».
Тут и простота целеполагания:
- Что делать будем?
- Может, просто улучшим жизнь?
- Работаем!
Одновременно резко очерчены границы улучшения качества жизни - при губернаторе. Тут временные границы, и социальные, и даже некая загадка оставлена.
Во-вторых, из документа, очевидно, пропал четвертый пункт.
Предписано:
1. Создать совет.
2. Утвердить положение.
3. Возложить контроль.
А вот улучшить качество не жизни не предписано.
Это недосмотр, или сразу так и задумали?

This seems like a great idea. If all the kids are offline, there is much less peer pressure to be online.
This solves the problem of kids being ostracized because their parents limited their screen time or didn't buy them a phone until they were too old.
