@maikel basically, it boils down to the few key features of #Monero:

1. #Anonymity & #Privacy: Unlike with any other #cryptocurrency (aka. #Shitcoins) it's not just pseudonymous in that there is no mandatory linkage between individuals & their wallets, but the entire transaction history and balance is hidden. Unlike say #Bitcoin or #Ethereum one cannot track the coins from the moment of mining to their destination.

2. Speed: Monero's network does mine one block every 2 minutes. After 10 blocks any transfered balance gets unlocked for spending. That means that a transfer is completed at worst within 6 minutes and the balance is being unlocked at worst after 24 minutes. This makes it faster than Instant-#SEPA which only has a 1 hour SLA.

3. #Fungibility: Like #cash all it's coins are equal, since they cannot be tracked. This makes Monero the digital equivalent of cash.

4. #Scalability & #Stability: Monero adaptively self-adjusts block sizes and mining difficulty based upon demand (transactions in it's mempool aka. requested transactions that have to be added to the blockchain) and supply (total blockchain hashrate). Unlike Bitcoin and Ethereum it has a fixed Tail Emission Rate of at least 0,6 #XMR (Monero) per block, so the miners solving it get at least 0,6 XMR (+ transaction fees), which is a longterm stable rate. Bitcoin and Ethereum will necessitate huge transfer fees once their last coins are mined to make sense, which will result in the crash of said cryptocurrencies as they'll be too expensive to trade!

5. Anti-#ASIC and focussed on #CPU|s of general-purpose machines: Whilst it does run on #ProofOfWork, it's specifically designed to run poorly on #GPU|s and not on #ASICs as the latter one are not just manufactured #eWaste but also inherently increase the centralization (with less than a dozen big miners controlling >50% of Bitcoin and Ethereum's hashrate respectably). Thus it's the "least worst" in that regard. #ProofOfStake is not possible due to it's privacy-based setup (#Staking necessitates a public balance) and unlike a #Shitcoin like #FileCoin it doesn't incentivize #hoarding components. (in this case: #HDD|s)

6. Accepted & Convertable: Whilst there is a concerted effort to ban Monero, there are payment processors like #NowPayments that accept Monero. It's low transaction fees and good speed make it useable in settings like Restaurants and Online Stores (sadly not retail, because it would need to be like 60x faster)... And even then it's easy to convert to/from Shitcoins.

That's the #TLDW of Whiteboard Crypto, Mental Outlaw and The Hated One

And finally:

7. Monero gets continously developed and enhanced, whereas Bitcoin, #Litecoin and Ethereum don't even do proper #upgrades via #HardForks (see #EthereumClassic)...

3 Тб данных на квадратный сантиметр: как работает молекулярный накопитель

Объемы цифровых данных растут экспоненциально. Соцсети, видеостриминг и облачные сервисы ежедневно производят терабайты информации, а технологии хранения — жесткие диски и SSD — все чаще упираются в физические пределы масштабируемости. Ученые из Австралийского национального университета (ANU) и Университета Манчестера нашли решение: одномолекулярный магнит на основе диспрозия, сохраняющий данные при температурах до 100 Кельвинов (−173 °C). Их исследование, опубликованное в Nature, сулит накопители размером с почтовую марку, вмещающие до 3 Тб на квадратный сантиметр — в сто раз больше, чем у современных жестких дисков. Это открытие может стать крайне полезным для всей индустрии дата-центров. Сегодня разберем, что там создали ученые и как это работает.

My /home directory was stored on a RAID 0 composed of two cheapish SSDs, and one of them already has "slow sectors".

I migrated it to the next best thing I had lying around: An array of 4 mechanical HDDs in RAID 10. (far2 layout)

You would think that HDDs would be painfully slow, but it's not that bad, actually.

It's very slightly slower, but it appears that 4 HDDs working together can almost beat a cheap chinese SSD.

I also remember backing up onto #floppy disks back in the day, but this has always been rather impractical.

The #IBMPC #XT had a 10MB #HDD and 360kB FDD, so with a 2:1 compression ratio, you'd need 15 disks to back the machine up.

This didn't change much in the early '90s. You had a 1440kB FDD, but you also had a 40MB HDD, so you'd need 14 floppies to back it up.

The introduction of USB HDDs, especially compact bus-powered ones, has *greatly* improved the #backup situation.

Хоронить HDD рано: Seagate выпустила самый вместительный жесткий диск в истории — 40 ТБ

Жесткие диски (HDD) все еще живы и даже не думают исчезать. Seagate, одна из крупнейших компаний-производителей HDD, представила первые в истории серийные накопители емкостью 40 ТБ. Это не просто рекорд, а серьезный технологический скачок. Он показал, что старый добрый жесткий диск всё ещё способен удивлять. Давайте разберёмся, что это за зверь, как он устроен и зачем вообще нужны такие объёмы.

I recently cancelled my Dropbox subscription, and will now be running local backups instead. For that purpose I need an external hard drive.

It seems most companies (Western Digital, Kingston, Seagate) are American, with Japanese Toshiba occasionally showing up in my search results.

Does anyone know of/have any experience with European storage manufacturers? If not I guess Toshiba will have to do. :)

And this isn't even the biggest difference...

Just the fairest comparison for #Windows with identical #hardware:

I've seen machines where #Windows10 on a SATA-6G - saturating #SSD got creamed by a 7200rpm SATA-II 7200rpm #HDD with everything else being the same.

So yeah, #LinuxGaming is the superior platform, cuz even #SteamOS does run circles around #Windows11!

Трамплин в интернет: как мы ускорили запуск Яндекс Браузера на слабых ПК

Привет! Это снова Максим из Яндекс Браузера. Мы с командой продолжаем делиться историями об интересных и неочевидных оптимизациях производительности, которые внедряем в наш браузер. В прошлый раз мы писали о том, как улучшили стабильность GPU‑процесса, воспользовавшись оптимизациями в драйверах видеокарт, сделанными специально для Google Chrome. А сегодня речь пойдёт об ускорении старта нашего браузера на Windows.

I am running #PhotoPrism on a Raspberry Pi 5 with 8GB of RAM, using a 1TB SSD as the main and only drive, using the Pimoroni NVMe Base.

So far, I could not properly measure the performance, because I don’t know how to do it, but I am satisfied! Yet, this is definitely not a future-proof solution, since I need way more storage: I still haven’t imported most of my pictures there, and I need to prepare for plenty more to come.

The simplest (yet quite pricey, 261£) option would be to get a Pimoroni NVMe Duo and maximize it with a total of 4TB NVMe SSDs.

I think this is not optimal, though, and probably I could be spending all that money much better… Do you have any advice?

The thing about hosting a personal media gallery is that it requires a lot of resources when indexing the pictures (so only when you add new ones), then it’s super light—correct me if I am wrong, @photoprism. Hence, I’m thinking the best would be an extensible solution where I can add many HDDs and SSDs, without being forced to pump up the other specs too. I would probably be using just one NVMe SSD for the software and the database, and then save everything else in high-performance HDDs, since they are getting cheap and I can get much more storage with less money—of course I am performing a daily backup off-site, as they are more likely to fail, too.

If I am 100% sure that whatever I end up choosing will be solid for many years to come, I am willing to consider spending a bit more on it.
