I was very surprised that my power company installed a smart meter that not only can connect to home Wifi, but also can regularly post statistics to a URL of your choice in a simple text format. No hacking needed!
Currently I run GNOME and I switch between dark and light modes back and forth a lot. Several mechanism have to employed to make a ubiquitous look across all applications and I wondered what would it be like in a DM-free environment. This post sheds some light– thanks!
In addition, I’d like to know what terminal emulator the author is using and how are modes handled for it. (Unless it’s all inside that Emacs, of course.)
spnw@emacs.ch - @jummo Ah yes, I cheated a bit by not showing my terminal emulator. I use st, which would require some hacking to make it work with this setup. I’m sure there are GTK terminal emulators that would just work. Also yeah, I do spend as much time as possible in Emacs, so it doesn’t bother me as much. :)
It’s so kind of you to go an extra mile for me!– thank you (-:
One option I thought about, but forgot to mention, is an xterm-compatible terminal and something like the following. Unfortunately, it wouldn’t work across all running instances of xterm.
IPv6 is a benefit dor everyone. As there is no possibility to generate more revenue with it, no manager will have it on their list.
Just a quick law to enforce all new Internet connection to provide IPv6 from date X. Like we have done it with ESP or safety belt for cars.
I really like XMPP and hope the EU enforce the interoperability for message apps. Even if the end-to-end encryption usage rate and and user friendliness of it will decrease.
Than we have it more like email with free to use provider and client.
It would do wonders if I could bridge to proprietary LINE for my daily life. When they discontinued their LINE Lite app (texting, voice/video calls, stickers, mostly stripped all other features—no food delivery, games, videos, timelines, even most ads/tracking was stripped), I didn’t choose to “upgrade”. After a month, the account was locked because it will not operate without a primary iOS/Android device (same as Signal (boo) & probably for similar encryption method reasons). I gave out 3–4 alternative contact options but 90% of the folks I’d known weren’t interested in coms outside LINE—even businesses make this problematic.
It’s neat. A concern though: If I bought a contactless square reader, I could ring up a charge and walk by you down a crowded street and probably make a transaction happen without your knowledge. That seems less than ideal.
With an Apple watch for example, you push the button twice, hold it near the reader and it vibrates a little at you when it’s successful. So it requires user interaction and it notifies you of success. Definitely more difficult to make it happen from just walking down the street.
This is a concern I have with all plastic NFC payment cards. The credit card providers just seem to accept a certain level of fraud as acceptable, but I can’t trust my bank’s debit card to undo fraudulant pickpocketed transactions.
I agree, but the distance on NFC cards is not very far, so if it’s in a purse and/or wallet, it’s fairly safe. On an arm which is unprotected as one wanders around is a different level of access.
I have one of those minimal wallets with aluminum panels. I’ve tested it a little with the door entry NFC reader at work. If the card is half way out of the wallet, I can hold it up right next to reader and it works. But less exposed or further away it does not.
I could do things more scientifically, but I can’t be arsed to dig through the storage room for a NFC development kit, or get the spectrum analyzer from the hardware devs. We used to have a small portable one with a multi-band antenna, but I haven’t seen it in a while…
So, yeah, if you’re concerned about this, just buy a metal wallet.
My NFC card requests to enter my PIN above 50€ and if I do several small payments in short time.
For me it’s a good balance between comfort and security.
I like SpeedCrunch, it’s my go-to calculator on PC. But why this submission has been tagged with “release”?
In SpeedCrunch Download page version 0.12 remains the latest, which is from 2016, as can be seen in repository Downloads page. And per repository Branches page last activity was in 2022. Did I miss something?
BTW two general side notes / gripes:
Download pages, change logs, almost everywhere where version of any project is mentioned would benefit from having version’s release date mentioned next to them (e.g. in parentheses). For some projects unless you’ll find source code repository or look at Last-Modified HTTP Response Header (and file has not been accidentally touch-ed since then) it’s hard to tell from when release is.
In the old times browsers could set downloaded file modified time (e.g. using utimensat on POSIX systems [mtime], SetFileTime on Windows systems [last write time], etc.) to this Last-Modified date, but sadly and reportedly users were using modified time (instead of creation time) to find latest downloads in their Downloads directories, thus all browsers that I know of abandoned this quite useful feature and do not want to add it, forcing me to download using curl with -R, --remote-time option or using other download tools / managers.
I miss in BitBucket one page showing tags and dates for repositories. Something like /tags and /releases in GitHub.
I was expecting to read about how the cheap hardware with open source firmware can be set up with all the features of expensive mesh networks, but that’s not what it was.
I don’t like expensive mesh networks because (a) expensive (b) tend to require special proprietary control systems (c) which often want logins and other privacy-violators. So I buy $40 wifi routers that are known to work well with DD-WRT/OpenWRT and set them up as follows:
all wifi radios set the same SSID
turn off 2.4GHz on the AP nearest the kitchen (microwave fun)
channels are set by hand for minimum overlap
NAT, firewalling, DHCP and DNS are turned off
Cat5e runs to the nearest switch port (three switches: office, den, living room, all interconnected)
Five of these cover the house and the back yard nicely. No meshing. No outside-the-house dependencies except power.
Recent versions support 802.11 r, k and v, but not on all radios. Support is necessary on both ends. If you aren’t active while moving from one ‘best’ station area to another, none of them are needed.
TP-Link Archer C7 with OpenWRT is great.
If you have a home server running a VM with OpenWRT and dumb Access Points from Mikrotik is fun and can cover easily cover multiple rooms/area/house.
AVM‘s FritzBox have DSL/Cable/LTE Modem or Fiber included had quick stable but expensive.
That sounds pretty great. Do you have a wiki/post breaking all of that down? Or least have solid suggestions for cheap routers? Sounds very interesting.
Most of my routers are TP-Link Archer C7, which are routinely on sale in the US for $45 each. If I see a sale on some new plausible router, my criteria are:
at least one gigabit ethernet port, preferably 4.
one for uplink to a switch, the others for local devices that I might want to position there
802.11ac and n on 2.4 and 5Ghz bands
the most usable protocols as of early 2023 – machines that were new in 2010 onwards use n, machines new in 2015 onwards use ac. ax has been out for almost 4 years and is still uncommon except on the newest phones and laptops.
known good firmware from dd-wrt or openwrt in the most recent stable release
It’s reasonable to get everything set up well on machines that don’t have open source firmware, even if they don’t support an AP mode, by carefully turning off all the things I wrote about before and avoiding the ‘WAN’ port.
I don’t trust any of these things as firewalls for outside connections, strictly as access points.
One good reason for having a low DNS TTL not mentioned in the article are DDNS setups.
Residential internet connections are flaky and sometimes a router cycles through multiple dynamic IPs in a matter of minutes, without anything the customer can do.
In practice stability of IPs has nothing to do with IPv4 vs IPv6. Some providers will give you the same IPv4 address for years, others will rotate your IPv6 prefix all the time.
Anecdata: this is true in theory but I’m not sure in practice? Specifically, I used to get the same IPv4 address for weeks at a time - basically until my modem was rebooted. Then in 2014 ARIN entered phase 4 of their IPv4 exhaustion plan (triggered by them getting down to their last /8 block) and all of a sudden my modem’s IPv4 address refreshed far, far more often, IIRC every couple days.
I guess maybe this was not technically required though, and was potentially just my ISP overreacting? 🤷
At least here in Germany will have a different IPv4 address every 24 hours or on reconnect for far most of residential Internet access.
The point with IPv6 is that you not only have one public.
But again in Germany it‘s even hard to find a not regularly changing IPv6 prefix for residential Interner access.
They think it‘s more Staat protection friendly… like cash.
Crazy thoughts.
Ideally, a v6 provider would give you two subnets, one for inbound connections that remained stable, one for outbound connections that was changed frequently. Combined with the privacy extensions randomising the low 64 bits, this should make IP-based tracking difficult.
The origin story of the 24h disconnect is that it used to be the differentiator between a leased line and a dial-up line, which belonged in different regulatory regimes (the most obvious aspect to customers has been cost but with a few backend differences, too). The approach has stuck since.
It’s also a (rather barebone) privacy measure against commercial entities, not the government: the latter can relatively easily obtain a mapping from IP to the address by giving a more-or-less refined reason.
Which is really weird, because implementing an “I’d like my IP to change / not change” checkbox would be trivial. I don’t get why that’s not more common.
That’s not going to be an easy problem to solve. We’ve embraced the current pseudo standards within home internet connectivity, maybe static, maybe dynamic IP, asymmetric speeds, CGNAT, no IPv6, etc. for so long that many people think that these are real industry standards with cost structures and cost savings behind them and we must suffer with them if we want cost effective internet connectivity at all. A lot of home ISP customers suffer from Stockholm syndrome.
I think that DynDNS.org is using a 60s timeout on A records so for a DynDNS/residential setup I think that the article author would approve of something like this:
foo.mydomain.com 14400 IN CNAME bar.my-dyndns-server.com
…
bar.my-dyndns-server.com 60 IN A 192.168.1.100
Specifically, I don’t think that the original author is complaining about the 60s TTL on records at my-dyndns-server.com since that company has to deal with the lack of caching in their DNS zones. He finds sub 1hr TTLs in the CNAME records to be a problem. And he finds CNAME TTLs shorter than the A record TTLs to be a bigger problem. Honestly even Amazon does this 60s TTL on dynamic resources trick.
I didn’t, and it’s way off-topic for here, but maybe someone in this thread knows:
I have been looking for bean-to-cup filter machine that has a burr grinder and drips into an insulated (not heated) jug. So far, I have found precisely one such machine to exist, it doesn’t ship outside the USA, and reviews indicate it often breaks after 6 months. Has anyone heard of such a thing being mass produced? Or a kickstarter or similar for one.
Welp, that router should hopefully be able to handle 25+ gbps… I wonder what the minimum useful specs would be, for some basic routing+firewall only? I got gigabit a few years ago and had to buy a beefier router to make it work, I was very confused for a while.
Can someone please explain the pros and cons of wiring your home with fiber? This article seems to skip explaining why they are going to the trouble of doing this.
Fast. You can lay fibre today that has longer reach at the same speed or higher speed at the same reach than copper.
Headroom. If you lay multi-mode fibre then you can almost certainly replace the physical interfaces at the ends without replacing the fibre. In contrast, if you lay Cat-6 today, GigE is your limit, if you lay Cat-7, the same is true for 10 GigE. The bottleneck for modern fibre is the transceivers at the end, not the cable.
Cost. Fibre is a lot cheaper than the Ethernet cabling that will handle high speeds.
Cons:
Cost. You need optical transcievers at the endpoints. These are more expensive than electrical ones, at least at the lower speeds.
Compatibility. Server NICs all support pluggable transceivers for optical connections but most laptop / consumer-electronics don’t. This means that you’ll probably want a switch with an optical upstream and an electrical downstream (or, ideally, a mix of optical and electrical) for rooms where you want the speed.
Diminishing returns. The jump from 10 Mb/s coax (shared bus) to a 100 Mb/s, full dupliex, switched network was huge. This is fast enough for multiple HD streams. The jump from 100 Mb/s to 1 Gb/s is smaller and you basically notice it only for large uploads or downloads (e.g. installing a game or backing up a disk). The jump to anything bigger needs workloads that I don’t have yet to matter. Possibly some immersive VR / AR thing will need that much, but for video the compression has improved quality a lot more than bandwidth increases in the last couple of decades. An H.264 720p stream now needs less than an artefact-ridden MPEG-1 320x240 stream used to.
If I were doing a new build, I’d be very tempted to lay fibre and cat6, so that I never have to think about it ever again.
IMO the biggest downside is that fiber is more of a pain to work with. You can unplug/replug your copper cables as much as you want, but you have to be careful not to scratch your fiber connectors or bend the cable
(yes, I know you can also kink a copper cable).
If you’re concerned about EMI (i.e. TEMPEST), then fibre also doesn’t have those emissions. The US federal government deploys a lot of fibre for that reason.
In case you happen to be a ham — fiber is RFI-immune. Longer copper ethernet runs can be prone to radiating wideband noise, as well as receiving RFI from nearby transmitters (which then degrades the network connection). Using shielded twisted pair is an option, but it’s nearly as expensive as fiber, and nearly as annoying to terminate as fiber. And, existing OM4 or OM5 fiber looks like it will manage 100Gbit links over in-house distances, which makes it more future-proof than Cat6A or even Cat8.
There’s plenty of usages I can think of that wouldn’t involve writing that to disk. Mostly to do with raw video transmission. Security systems, playing video games in a central beefy computer from a portable peripheral (Steam and Playstation support this), keeping video in a NAS and editing from around the house…
I was very surprised that my power company installed a smart meter that not only can connect to home Wifi, but also can regularly post statistics to a URL of your choice in a simple text format. No hacking needed!
Which smart meter do you have?
It is an Itron, but I think the firmware is specific to Xcel Energy, one of the big electric companies in the central US.
The Acardeur is a great system. I played it in a Hotel in Cologne. Unfortunatley, just too expensive for me.

This is why I select hardware with a focus on openwrt.
The box can run OpenWRT, see AVM FRITZ!Box 4040,
It sure can, but if you’re buying for OpenWRT, it’s unlikely this device will get selected.
It’s not hard to get better hardware for cheaper.

Commercial entities have “solved” the tracking issue by using cookies etc.
I.e. customers prefer changing IP addresses for privacy reasons?
Which is really weird, because implementing an “I’d like my IP to change / not change” checkbox would be trivial. I don’t get why that’s not more common.
The checkbox isn’t the complicated part here.

Pros:
Cons:
If I were doing a new build, I’d be very tempted to lay fibre and cat6, so that I never have to think about it ever again.
you also can’t do PoE for things like cameras or access points.
Very minor nitpick – I believe 2.5GbE and 5GbE were designed to run on Cat-5e and Cat-6 respectively.
ref: https://en.wikipedia.org/wiki/2.5GBASE-T_and_5GBASE-T#Technology
You can actually even do 10GbE over Cat-5e if the run is short enough.
From what I can tell, if you already have SFP slots, optical transcievers are cheaper. For example
IMO the biggest downside is that fiber is more of a pain to work with. You can unplug/replug your copper cables as much as you want, but you have to be careful not to scratch your fiber connectors or bend the cable (yes, I know you can also kink a copper cable).
Thanks. It’s been a little while since I looked and the price for the optical transceivers has come down by over an order of magnitude since then.
If you’re concerned about EMI (i.e. TEMPEST), then fibre also doesn’t have those emissions. The US federal government deploys a lot of fibre for that reason.

Apparently they have a 25gbit connection so I guess you need this to even begin to take advantage of it.
Seems like a crazy amount of bandwidth though - 25gbit, 10gbit AND a 5G backup.
isn’t this too fast to write on a regular SSD? if we take the 550MB/s write speed, how would you benefit from a 25gbit connection?
Use the memory. And Init7 charges the same amount for 1G, 10G and 25G
There’s plenty of usages I can think of that wouldn’t involve writing that to disk. Mostly to do with raw video transmission. Security systems, playing video games in a central beefy computer from a portable peripheral (Steam and Playstation support this), keeping video in a NAS and editing from around the house…
But yeah, that’s a ton of bandwidth.
