В Linux стандартными средствами можно использовать часть оперативной памяти как диск. Для этого требуется указать тип монтирования tmpfs в команде mount
mount -t tmpfs -o size=5G tmpfs /mnt/ram
Теперь путь /mnt/ram можно использовать как обычный каталог. Для чего это может быть нужно?
▫️ Скорость работы с таким каталогом выше чем многие SSD и тем более HDD.
▫️ Если у вас очень быстрый SSD на NVMe M.2 то такой способ особо не прибавит вам скорости, но поможет сохранить ресурс SSD когда требуется обрабатывать очень много мелких файлов и оперативка позволяет выделить нужный объем.
▫️ Оперативка это энергозависимая память, поэтому выключении питания все файлы безвозвратно теряются. Такой "non persistent" каталог гарантирует удаление временных файлов.
Я написал небольшой скрипт для условного теста и сравнения скорости копирования файлов между SSD и RAM.
Вот мои результаты:
Single File Size: 30.0Gb
ssd > ssd: 0:00:12.850 / 2.3Gb/s
sdd > ram: 0:00:06.453 / 4.6Gb/s
ram > ram: 0:00:06.995 / 4.3Gb/s
ram > sdd: 0:00:06.217 / 4.8Gb/s
Dir size: 32.7Gb, File count: 11127
ssd > ssd: 0:00:15.063 / 2.2Gb/s
sdd > ram: 0:00:08.486 / 3.9Gb/s
ram > ram: 0:00:08.032 / 4.1Gb/s
ram > sdd: 0:00:07.026 / 4.7Gb/s
Скрипт для теста ↗️
На моём железе прирост скорости ~2x. Плюс экономия ресурса SSD.
В Windows такой фишки по умолчанию нет, но обязательно найдутся аналогичные решения

Matthijs de Ligt:
“Since November I have done everything, pushing myself in every session and exploring every option, to get back to doing what I love, playing football.
“I am grateful to everyone who has supported me throughout a difficult period in my career. I remain as determined as ever to represent Manchester United and play in front of our incredible supporters as soon as possible.”

Matthijs de Ligt Ig: “After 6 months of treatment and working hard to get back, surgery was the only option left. I’m disappointed I couldn’t help the team the last 6 months and obviously missing out on the World Cup but I am looking forward to doing everything to get back in front of the fans and feeling better again 🙏🏼💪🏼” #MUFC
Matthijs de Ligt has undergone successful surgery to adress a back injury, say Manchester United.
They say De Ligt will begin a new phase of his recovery and is expected to return for United in the early stages of the 2026/27 season.

Michael Carrick on #mufc's future targets:
"You’ve got to aim upwards. That’s the beauty of football, beauty of competition to achieve something and back it up, that’s the challenge.
"For the players, for the squad, for the whole group and football club we want to keep moving in a positive way and in the right direction.
"The closer you get to the top the less room for progress, but progress is what we’re aiming for."
Jamie Carragher on his ‘leave football before it leaves you’ comments on Casemiro:
“In retrospect, do I regret my comments about such a legendary footballer? Yes and no. It must be acknowledged that the implication that Casemiro was 'finished' at the highest level was too harsh and premature.
“My argument was he would be better heading out to the MLS, or accepting offers from Saudi Arabia, because he would never get back to anywhere near his best to achieve the same heights of winning the Champions League or league titles at Old Trafford as he did so brilliantly at Real Madrid.
“At the time, those observations were not controversial. In 2024, Casemiro was unfit, lacked the physicality and athleticism to cope with quicker, sharper opponents, and was exposed when used in a deeper role, either in midfield or at centre-back as he was that night at Selhurst Park.
“This week, Casemiro suggested my remarks were 'disrespectful', and that is fair enough. Anything he says in response comes with the territory, although I would counter and say no disrespect was intended. Quite the contrary.
“Because of his stellar career, it was natural to compare Casemiro to the extraordinarily high standards he set for himself.” #MUFC [Telegraph]

🚨 Manchester United are proposing an initial TWO-YEAR contract offer to Michael Carrick until 2028!
Talks are now underway after co-owner Sir Jim Ratcliffe gave the go-ahead following an executive committee meeting this week where chief executive Omar Berrada and director of football Jason Wilcox made the recommendation for Carrick to get the job full-time 🔴 [Laurie Whitwell, The Athletic] #mufc

Michael Carrick’s backroom staff are expected to stay, with Steve Holland, Jonathan Woodgate and Jonny Evans all in line for new deals. Craig Mawson is also set to continue as first-team goalkeeping coach following his promotion after Ruben Amorim’s departure.
#mufc also want to add a set-piece coach, with Andreas Georgson, highly rated during his previous spell at United, among the contenders to return from Tottenham

Bruno Fernandes:
“I’ve always said, Declan Rice was a player to play for #mufc, I was really sad when he chose to go Arsenal.
“I always thought he would be a PERFRCT fit for our club.”

Excl: #MUFC plan to offer Michael Carrick an initial contract of 2 years until June 2028 with a 1 year option to extend. No formal negotiations have begun so no agreement yet. The 44 yo has been involved in recruitment meetings for the summer.
