I have already created a croos-platform solitaire game in Rust with Opus 4.5. Done in one evening. I absolutely do not understand why OpenAI could not write a proper application in 6 months. Do they struggle to use the product they sell?

ROCE do require proper nic/switch tuning. But if you go all in on Mellanox NIC's and switches, its basically on knob on the switch: roce If you buy CX3 and Mellanox SX6036(easy fan adjustment and low power usage) switches on Ebay

Yes, nfs with rdma will increase your performance significantly.

I fully agree with the author, and I have stayed on vanilla JS for decades now. I like the simplicity, ownership, zero dependecies. I have my own bundler in Spring Boot using Google Closure Compiler, which works autonomously with the javasc

The MSSQL developer experience is ok, until you want to pipe the backup over ssh. Then you understand that the Linux support is a joke, with no stdout( https://linux.die.net/man/3/stdout ) support.

Yes CX5 can offload more. I believe CX4 has similar offloading capabilities as CX3, except that it supports 100G. Another note: In my experience, RoCE works much better on CX4+ generation. CX3 is best with Infiniband. I think some firmwares

Maybe you have priced it wrong? I just checked Ebay, a 16GB 12800 Registered ECC module goes for 40-50USD ea. That is crazy! Last year they were like 5 USD each.

With NVMe-oF and RDMA I can saturate a 25G link with spinning disks easiliy with around 16 drives.

I disagree, I play a lot around with enterprise stuff. Its insane that I need to buy enterprise grade hardware that costs 1000x more for lab/experimentation/learning. My only alternative is to wait a few years, and get it from Eba

We're a self hosted shop, we went with Valkey. Valkey also has support for RDMA, which we already is running in our infrastructure.

But that is his point. If you cannot find the session id in redis, you login again. If your Redis server crash, you start a new one and everyone just login again. No data is lost.

When I look at the oil & gas sector, I remember MS-DOS + Wordperfect was the beginning. Then Windows 3.1 + Microsoft Office took over, and since that, its been Microsoft, Azure, and SAP. They refuse Google Cloud, AWS, and many still bel

Every time I give Photoshop a chance I give completely up, the thing doesn't even start on neither Fedora or Ubuntu and I have no interest in configuring Wine for this. GIMP is the least painful way to get the job done. I have been usi

It is a bit different, Mellanox with iSCSI/iSER over IB/RoCE is much less complex than iSCSI over TCP. RoCE runs over UDP, but requires switches with PFC, and ECN. Chelsio plays nice with any switch. Mellanox has much better offlo

ZFS supports self healing, you do not have scrub, it will be corrected during a bad read as long you have a copy. Metadata has 2 copies by default for additional safety for a single disk.

Using a proper NIC (Chelsio) with their iSCSI accelerator will boost your iSCSI performance significantly. Another alternative is Mellanox with RDMA. You need CX4+ for optimal performance over TCP/IP, while the cheap CX3 is excellent w

A 42U rack filled with 1u servers with 8 drives each, will have 84PB of data. It feels like it was a few month ago where you could buy a rack with 1PB of storage, and that was awesome. Not anymore.

I would not worry about running a distro. Most things are similar, there are some minor differences between the GNU applications and the FreeBSD alternatives. But for most people there is nothing to worry about. Most applications runs fine

I just started with FreeCAD this weekend, and in 3 hours I managed to create a simple pci bracket that I could 3dprint. I just followed some YouTube tutorials. When I learned 3D Studio Max 25 years ago, I struggled a lot more.

Gitea is one of the easiest projects to to self-host. And to do regular upgrades, you only need to update one file. It has been a joy to self-host for many years now.

You are correct that writes are not guaranteed to be atomic. PostgreSQL has a feature to handle torn pages: full_page_writes = on, which is enabled by default. This means you do double write. For RocksDB I believe torn pages are not a probl

I have tried multiple enterprise SSD's, for sync writes. Nothing comes close to Optane Dimm, even Optane NVMe is 10x slower than PDIMMS. https://forums.servethehome.com/index.php?threads/so-i-teste...

Its not only about performance, Redis data structures offer an even more advanced caching and data processing. I even use Redis as a cache for ClickHouse.

The biggest advantage of ZFS from a operational experience, is that when you have problems, ZFS tells you why. Checksum errors? Something wrong with the hard drive or SATA/SAS cables. Is the disk slow, zfs events will tell you that it

ZFS snapshot, send, receive, clone, spin up another postgresql server on the backup server, take full backup on that clone once per week

I actually always build PostgreSQL from source as I want 32kb block size as default. It makes ZFS compression more awesome.
