With computers like framework and system76, the community for hardware support is solid too now. Seriously considering a switch from M1. I feel like macOS is half baked development environment. I only stay because I never bought a Linux supported computer and I got the M1 air very cheap. But I am considering getting a framework as I just damaged a usb-c port and I am not entering apple’s repairability problem.

> Hope as an industry someday we can get back to simplicity

The services upon services with no idea what underlying layers are doing and pretty much enterprises collaborating to get stuff 'out the door' means we may not go back to simplicity easily. At this point I am only finding work who are basically middleware and rarely doing something unique even there. Basically getting contracts and servicing a business need is all that I see when I try to find jobs these days. Initially I was doing something quite unique in networking but now that the client needs have changed its basically just another product that is servicing clients which big companies like Arista can't do for them as there are custom requirements.

The thing about reliability is that not every single thing needs to be ‘reliable’. The reliability comes from knowing the failure points. Some issues you may not be able to fix right away but simply knowing why something fails is more reliable than not knowing. And that’s the scariest problem I’ve seen. Not knowing failures.

Just don't use wifi or connect your TV to the internet. That works for me. My TV is online only during firmware updates which almost never happen cause its become old and those stopped long time ago.

I use an iPhone and other than that I hope to not use anything else that’s so cloud reliable. Maybe an AppleTV if I get one, but I only watch sports so a few cable channels are more than enough for me I think.

It’s like a football (soccer) team. Yes the players are playing and scoring goals. But a great coach (SAF) is just as important as a great team. Without him, the same team doesn’t perform the same.

Ah okay missed it. So not QF. I was hoping someone does QF at home :P

QuantFinance.

Money in the stock market (or crypto market but similar) is probably the only way to justify tens of thousands of dollars worth of GPUs that become obsolete quickly.

The other thing I can think of is Reseach scientists who use it for research. But funded research scientists that I know generally don't get hardware to take home. They usually either get tons of cloud credits or time on a supercomputer to do their stuff.

This is mobile phones dominating that number. Almost every 4G / 5G phone right now uses a dual stack IPv4/6 connection. This is not necessarily problematic but home broadband is still lagging by a lot. I sometimes never get a prefix assigned. I have to redial PPPoE as IPv6 link uses IPv4 session. It's not plug and play for home broadband unless you use their modem router combo which has other issues.

The big ones do. Small ones are small for a reason.

From a data perspective it's interesting that confidence reduces when a military isn't in an active war zone. But then again if you think about it, it makes perfect sense. I wouldn't know about an accidental breakage system or be confident in one unless I saw it being used in a scenario successfully. So it's more of a psychology thing rather than whether the military is actually reliable. Cause if anything the US military is still the best one in the world and will continue to be. But one can only be confident about this statement as long as it's in an active war zone. Sounds like Shrodingers thought experiment with a default as negative in this case.

If you look at systems like Deco (and a bunch of others I've noticed recently like linksys) the devices have stopped being dns forwarders themselves to clients and instead they assign your ISP (or the ones you've set for your ISP) DNS directly to clients. This means your device now resolves dns over wifi directly. This means each device is now relying directly on google and cloudflare instead of relying on the gateway (which being wired will experience the lowest latency especially when it comes to redirects and should ideally have a robust DNS server).

A local network resolver instead of forwarder on a client seems to work a lot better in my experience especially when I use root DNS on unbound. Yes a root DNS is a lot slower than something like 8.8.8.8 but you could use an upstream dns with unbound if you really want something faster. Either way, a local DNS will be lot less problematic compared to if you devices has to handle all dns over wifi including the redirects (which happen a lot).

Almost every time I see a network problem, it's always a DNS problem. In a typical home network setup these days:

client DNS cache -> upstream DNS -> root DNS. client DNS cache -> local DNS - > upstream DNS -> root DNS.

My setup:

client DNS cache -> local DNS -> root DNS.

The first one works better if the network is wired. Second and third one works better on wireless.

One alternative that works 'okay' is if the client directly uses DoT or DoH for DNS. TCP works little more reliably than UDP (wink) but neither Google nor Cloudflare offer signed profiles for iOS and macOS (third party is there). Stubby works good on linux and android and windows have a built in solution.

Almost all ISPs use Serial and (optional) PLOAM to authenticate your ONU. Nokia GPON SFPs allow you to change almost everything that is exposed to the ISP for authentication. ITU standards mean that ISPs have to work according to the spec.

ISP ONUs are locked for easier management for them. They will give you 1/10th of the speed promised if it helps them deal with support calls remotely rather than visiting your place to fix it. Support calls where people complain for things like 'I forgot my wifi password' cost ISPs a lot of money. So they can basically just login to your ONU at any time remotely and change settings for you like your wifi password. They do remote firmware updates and what not remotely. This is the biggest reason why ISPs love such modem router combos. Support can be guaranteed with a phone call to fix your wifi for the average Joe.

You will not get ISP support if you use your own ONU but if you are using your own ONU then you are already at that point where you know what you are doing. As far as signal issues are concerned, like I said ITU specs mean they can see the signal strength remotely. Everything else they don't have access to but you don't need them to have that access. You can always swap out the ISP provided box to troubleshoot.

If you actually swap out the ONU to a better one, chances are you'll never need to call your ISP unless there is a fiber cut or some serious signal loss somewhere.

Biggest problems I have faced for home networks : ISPs are poorly configured and do very shady things sometimes like DNS hijacking. More often than not poor ONU firmware or hardware means you will see weird things like latency spikes or straight up packet drops. Sometimes IPv6 won't work if the ONU is in bridge mode etc. etc.

This post is overkill but what mostly works for home networks:

SQM - like cake sqm in openwrt - will work wonders if don't have a great ISP. I have seen as much as 5% packet loss on one ISP who said thats acceptable for a home network. Just reduce the load until a point where packet loss is really low. Then use a DNS resolver. DNS resolver will be much more reliable like unbound for your local network as packet loss has cause really problems with DNS for me. Cheap home network equipment dns is not reliable. You could really just buy a cheap Pi and run a local resolver. It would work a lot better than your home router. You may also want to consider replacing the ONU. This is rather easier than you think. The ISP ONU are really bad. A cheap NOKIA SFP GPON is like 20$ on eBay and if you can figure out the PLOAM password and Serial and Mac and VPN ID of your ISP, you will be able to simply swap it for a more stable link.

All in all I would suggest for a simple home setup: get a cheap SFP GPON and replace your ONU. Get a cheap router (either router on stick with Rpi4 for <500mbit or x86 box with SFP for hitting 1gbps with the SFP GPON) and run your own unbound resolver. Get some APs and either wire them or get a cheap mesh router 3 pack on amazon (you can get a wifi 6 3 pack for under 150$ these days on sale) and run it in AP mode.

I’m guessing there are no environmentally friendly alternatives to these materials than can be easily swapped in factories without much hassle.

You should see his interviews with Dr. Ian Cutress. The man basically knows everything in the industry in and out and knows how to create great teams. I want to interview for Tenstorrent at some point and would love to work for him. I feel being part of great teams is what he has been fortunate with. People very easily forget the rest of the team in chip design and make it about one person. I feel he's a true leader in chip design teams, but I also think he has worked with many great people to achieve that.

I just got a new USB-C monitor that delivers 65W watt. I think something like this would be a wonderful desktop for me and I might just get one for a desktop.

Reveal it to whom? Sounds like the game already knows which websites you’ve visited without you clicking on them.

The biggest reason I like xSense is because of unbound and using root dns. OpenWRT supports that, but otherwise I have to setup a local linux instance to serve DNS via unbound. With pfsense and opnsense I find that the dns is a lot more stable than unbound as using a resolver seems to work more reliably than a forwarder like dnsmasq.

What I find easy(ier?) is to run (x)sense on a dedicated firewall and either a mesh with cheap openwrt routers or get something like Deco mesh and run it in AP mode if you don’t have cat6 at home. I think this combination can be under 300$ for a 3-pack of mesh Deco x20 + an intel card on a refurb dell optiplex.

UPI is a modern marvel tbh. Can't praise it enough.

Microsoft had a good licensing model that sort of worked. Instead, they are going towards selling malware for free or at a very low cost to manufacturers. It is kind of sad. The UX on Windows 10 for me still feels better for an average Joe compared to Apple and Gnome or KDE. Windows 10 also had WSL2 which made it an okay development system. Then they made a UI that sort of drifted off into something unknown and put in a bunch of telemetry and spyware. Their browser is now riddled with ads. Microsoft and Google have such talent, then talent that is basically making large surveillance software at this point.

Yep. I think they would throttle under heavy sustained load. But I don’t think these are for sustained load or home servers. Probably designed for places like traffic cams where maybe large image models need ram and prefer no moving parts that can fail. Even places like factory floors.

A temporary solution would be to block all traffic of email to ml domain on computers and vpn used by the military and respond with an error. If anyone outside military computers and emails is sending such classified information this is a bigger problem and not just a typo issue.

Update: missed the part that this is incoming emails problem from non military.

I think super micro makes such edge devices. But then we are talking a different category now.

I just searched for N100 on Amazon and I could find ones for 160$ with 8gb ram and 256gb ssd. What an incredible value. Compared to this I’ve spent well over 80$ on my raspberry pi 4gb (cases ssd cooling charger etc). Sure a pi4 is low power. But I find it less appealing for those wanting simple cheap home servers now that things like these consume less power and are much faster with much better I/O and cooling. Not to mention upgradable memory.

goal is to minimize costs from a big provider by buying in bulk. Something similar to spot instances.

Is there a way to buy droplets for a year at a time? Like 40$ for a year would be a sweet deal for the $4 droplet. Especially for things like PiHole and wireguard.

>Alas, how many of those users know they are running Linux is another question.

That's the whole point. Probably 99% of computer (anything that uses a processor I guess qualifies a computer these days) users in this world don't really care what's running underneath as long it gets the job done. If something can run linux underneath and can still pass as acceptable that's a huge win I think.

Makes me wonder if the couples real reason is not the smartphones in this article but the fact that the relationship is already incompatible to begin with.
