> here is no network protocol for a host to control traffic filtering on upstream providers (deny traffic from certain subnets or countries).

There is no network protocol per se, but there is commercial solutions like fortinet that can block countries iirc, but to note that it's only ip range based so it's not worth a lot

I'm pretty sure BGP magic will let you blackhole a whole subnet.

Early this year I started redoing the backbone of my home network with 10 gb. Some of it's fiber, some of it's 10 gb copper Ethernet. It's been genuinely frustrating the weird incompatibilities between switches and SFP+ modules.

All my switches are MikroTik. My SFP+ modules are MikroTik, Ubiquiti, and some 3rd party ones from before I knew better.

I've had modules that will only run at gigabit in one switch but will give me the full 10 gb in another. I've had modules that refuse to work in one MikroTik switch but will happily work in a different MikroTik switch. I've just had a world of pain.

I've got everything basically working after months of fiddling and I'm inclined to just not… touch… anything.

I've had great luck with 10gtek modules both with Mikrotik gear, with DACs, and one that is connected to an upstream juniper switch. I'm curious what modules were the most troublesom.

* I will note that the 10gb sfp+ modules from 10gtek on a Mikrotik just don't work.

Can you do the installation yourself? In my country i have to make a HVAC technician come to check the installation and sign a paper before i can start mine (200€ for a 15 minutes job, but it's less than the 2-4k it would cost to not do it myself)

[edit] i say that because my hardware is 2.5k euros, so ~3k¯dollars, so we probably have the same high end stuff, and i guarantee you it's not hard to install, and it can be quite fast if you have help from your SO.

Newer units (not all) in the US come pre-charged up to a certain size of lineset. Manufacturers can sell you a whole unit with a charge. The rest is easy to source locally though I haven't tried to get nitrogen myself.

Of course you have exactly one chance with your install this way until you have to call someone.

There's a big difference between used as in I just bought this hard drive and have used it for a week in my home server, and used as in refurbished drive after years of hard labor in someone else's server farm

jabart · 2 months ago

Enterprise drives are way different than anything consumer based. I wouldn't trust a consumer drive used for 2 years, but a true enteprise drive has like millions of hours left of it's life.

Quote from Toshiba's paper on this. [1]

Hard disk drives for enterprise server and storage usage (Enterprise Performance and Enterprise Capacity Drives) have MTTF of up to 2 million hours, at 5 years warranty, 24/7 operation. Operational temperature range is limited, as the temperature in datacenters is carefully controlled. These drives are rated for a workload of 550TB/year, which translates into a continuous data transfer rate of 17.5 Mbyte/s[3]. In contrast, desktop HDDs are designed for lower workloads and are not rated or qualified for 24/7 continuous operation.

From Synology

With support for 550 TB/year workloads1 and rated for a 2.5 million hours mean time to failure (MTTF), HAS5300 SAS drives are built to deliver consistent and class-leading performance in the most intense environments. Persistent write cache technology further helps ensure data integrity for your mission-critical applications.

I admire the courage to store data on refurbished Seagate hard drives. I prefer SSD storage with some backups using cloud cold storage, because I’m not the one replacing the failing hard drives.

Every drive is "used" the moment you turn it on.

I am considering dotnet Maui for a project. On the one hand, I am worried about committing to the Microsoft ecosystem where projects like Maui have been killed in the past and Microsoft has a lot of control. Also XML… On the other hand, I’ve been seeing so many impressive technical things about dotnet itself. Has anyone here used Maui and wants to comment on their experience?

jabart · 3 months ago

MAUI Blazor Hybrid is great if you won't want to learn XAML. Apple killed Silverlight, Microsoft kept it running for ~20 years. If you stayed close to what Xamarin was the migration to MAUI isn't bad from what I've seen.

Hmm. 80B. These days I am on the lookout for new models in the 32B range, since that is what fits and runs comfortably on my MacBook Pro (M4, 64GB).

I use ollama every day for spam filtering: gemma3:27b works great, but I use gpt-oss:20b on a daily basis because it's so much faster and comparable in performance.

Can you talk more about how you are using ollama for spam filtering?

Microsoft owns 49% of OpenAI so why they should worry? JetBrains just proudly announce that they now use GPT-5 by default.

> going all in at the begining and then losing to the competition

Sure, but there are counter examples too. Microsoft went late to the party of cloud computing. Today Azure is their main money printing machine. At some point Visual Studio seemed to be a legacy app only used for Windows-specific app development. Then they released VSCode and boom! It became the most popular editor by a huge margin[0].

Visual Studio is a bad example. It's used for Windows, Web, and Mobile. The big difference between the two is the cost. Visual Studio Pro is $100/month, Enterprise is $300/month, while VSCode is free. It was an incredibly smart marketing play by Microsoft to do that.

I wasn't involved in the specific details but I remember being told that during the power outage from hurricane Sandy, even datacenters that had sufficient generators had trouble getting the diesel to keep them running, because everyone wanted diesel at the same time and both the supply and distribution were bottlenecked.

How long can most DCs run with just the fuel onhand? Have standards around that changed over time?

jabart · 4 months ago

At a call center, that had a whole datacenter in the basement. They had two weeks of fuel on hand at all times. Being on a border of a state, they also had a 2nd grid connection in case one failed.

The whole area lost power for weeks but gym was open 24/7 which became very busy during that time.

jabart commented on QUIC for the kernel lwn.net/Articles/1029851/... · Posted by u/Bogdanp

yello_downunder · 5 months ago

QUIC would work okay, but not really have many advantages for machine-to-machine traffic. Machine-to-machine you tend to have long-lived connections over a pretty good network. In this situation TCP already works well and is currently handled better in the kernel. Eventually QUIC will probably be just as good for TCP in this use case, but we're not there yet.

You still have latency, legacy window sizes, and packet schedulers to deal with.
