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 #linux#triks

Have you been returning your trays and binning used tissues? A large majority of people surveyed agreed that litter left behind poses a public health risk. However, whilst 90% felt that diners should clear their tables after eating at public dining places, the average tray return rate at most hawker centres is only around 30%.

Phase 3 of Re-opening commences today. To accommodate the increase in group size of up to 8 persons, markings on seats and tables at the dining areas of hawker centres have been revised. While we bond over our favourite hawker food, let’s also #ReturnOurTrays and #BinOurTissues. #OurHawkerCulture is not just about the heritage, great food and bustling ambience – it is also about how it brings people from all walks of life together. Let’s keep #OurHawkerCentres clean and safe for everyone 😊 Access control and interim fencing at more markets will also be removed, details at https://www.nea.gov.sg/media/news/news/index/phase-3-of-re-opening-hawker-centres-and-markets

We are all looking forward to dining in again at our favourite places. Let’s not forget good dining habits at #OurHawkerCentres to mitigate the spread of COVID-19! #BinOurTissues & #ReturnOurTrays, to keep the table clean for the next user and reduce the risk of disease transmission to cleaners and other members of the public. Eat from your tray, and don’t leave behind soiled tissues or wet wipes on dining tables. #FightCOVID19#SGClean

Don’t leave your used tissues or wet wipes behind when dining at #OurHawkerCentres! It is important to dispose of used tissues or wet wipes which can be highly contaminated, to #FightCOVID19, especially as we resume our activities gradually. From 19 Jun when dining-in resumes, Safe Distancing Ambassadors at hawker centres and coffeeshops will be on hand to remind patrons to be socially responsible and observe personal hygiene. Let’s all do our part to keep ourselves and those around us safe. https://go.gov.sg/nea17jun20-hygieneathcs-toilets #BinOurTissues#ReturnOurTrays#SGClean#KeepSGClean

Let’s remember to stay at least a metre apart from each other. We wouldn’t want all the effort and resources of the past few months to go to waste. Dining in at #OurHawkerCentres? Let’s not forget to #ReturnOurTrays and #BinOurTissues after enjoying the meal! #SGUnited#SafeDistancing#FightCOVID19
