Side comment about the difference between “My server is a phone now” and “My phone is a server now.”

In linguistics, the terms “theme” and “rheme” refer to the status of information in a sentence [1]. The theme of a sentence is something that is known or can be assumed from the context (that is, old information), while the rheme is information that is newly introduced in the sentence, often as a comment on the theme. The tendency in many (most? all?) languages is for the theme to precede the rheme in connected discourse.

Without context, a reader is therefore likely to assume from “my X is a Y now” that X is something the writer had previously and that Y is something new. Because most people have a phone but few have their own servers, I was initially confused by the title “My server is a phone now.” I had to read the article to realize that the word order is in fact appropriate: for the writer, the server is old information (something he has had for a while) while the phone (as a server, at least) is new.

In English, theme and rheme might be inferred not only from the position in a sentence but also from how a noun is marked. Possessives like “my” are generally used before nouns referring to things that are previously known or assumed; the definite article “the” is similar. In contrast, the indefinite article “a” (or “an”) usually marks information being newly introduced, so it is more common with rhemes.

I worked as a Japanese-to-English translator for many years. Because the grammatical structure of Japanese sentences is very different from that of English, sentence-by-sentence translation often ends up with paragraphs where the information flow is awkward and unnatural. I gradually learned that I could produce smoother translations by reorganizing my English sentences into an old-to-new information sequence.

I wonder if this is a native/non-native English reader situation. I'm the latter and for me the title promised that I will read about a server that now is capable of letting a person call to order a pizza. That was immediate thought.

It would be very interesting to see a poll results on how many of us thought that the article is about a server doing phone stuff and not a phone doing server stuff.

I don't think so either, as a native English speaker, I originally read this as my server now has phone capabilities, not my phone is now being used as a server.

I don't think it is, I'm also the latter and happened to assume the opposite. The article was exactly what I expected from the title.

I mean, turning a server rack into a phone just isn't something that makes any sense, so it didn't seem like a valid option to consider. I've thrown it at a few LLMs now to see what happens and they also make the same assumption with no extra info, that it's a server now being hosted on a phone. That's the statistics talking. It's very unlikely to be the opposite.

Of course it's clear which is more likely in this specific case, but from the semantic structure I read (present tense) it the other way around. It actually struck me as a grammatical error when I first read (past tense) it.

If I said "my water is ice now," one would assume freezing rather than melting.

So in this case one would assume a server became a phone, when actually a phone became a server.

(English is my first language.)

If you asked any native English speaker what “my X is a phone now” meant, I would wager that nearly all would say that it means that X can now make voice calls, like a phone.

Isn't there a simpler explanation in that "my server" can refer to a role or to a specific machine?

The author uses "server" as a role. So "my server is a phone now" translates to "the server role in my setup is now played by a phone".

Maybe this is just a rewording of what you said. You clearly know a lot more than me about linguistics.

In that case it would still be more clear to say “my phone is my server now”.

The current title is just a bad English construction. Not a big deal and absolutely forgivable since I don’t expect everyone to know perfect English.

tkgally

Yes, I think that’s a rewording of what I said. As you point out, the word “server” in the title refers to a role, not to a particular device. But that role is, for the writer, something that is already known, so it comes first.

This theme-followed-by-rheme is only a tendency, not a hard and fast rule. In casual conversation, people do tend to structure their sentences that way without even thinking about it. In writing or translation, though, a sentence might need to contain a lot of different elements and, in the process of arranging them, a writer might put the rheme before the theme. Readers might think the resulting sentence seems a bit awkward, but they probably won’t be able to pin down the reason. This “My server is a phone now” title was an exception, because (as the comments below show) some people were confused enough to remark on it.

Regardless it is extremely poor phrasing and would have been easily addressed by using "My phone runs a server now".

It's borderline clickbait, unless the author is an English graduate and assumes all their reader will be too. A phone running a server is not very interesting and has been shared many many times on HN before, while I've not heard of a phone running on a server before (which I why I clicked at all).

"My phone is a server now" - OP's choice is a subtle one.

By saying "my server is now ..." implies a change of server platform to a phone but not where it came from.

Some newer phones support bypass charging, which powers the phone directly instead of continuously cycling the battery. Mine doesn't support that, unfortunately, so I've limited charging to 80% to reduce battery stress.

That's surprising to me. It's been a standard feature on laptops for 20 years.

> or is it fine to just limit the charging to 80%

LiPo batteries will fail over time if left fully charged. If you don't need the battery it's best to keep it somewhere around 40%. If 80% is the only option, that's usually good enough.

The primary failure mode starts when the cells are charged near their maximum voltage and kept there.

Afaik mobile electronics’ power circuitry is designed so that power goes straight from charging port to the processor, without constantly charging/discharging the battery, once charging is complete. Unless the system suddenly draws a lot of power (more than the charger is supplying) - which is unlikely in a smartphone.

rcxdude

This is true but lithium-ion batteries degrade even while not being charged or discharged, and this is worse at the extremes of the state of charge (including fully charged), and at higher temperature (and often a plugged in device is on constantly and therefore spends more time at a high temperature than it normally would), so it's still not great for the battery. A lot of devices have a mode where the batter is kept at a lower state of charge if it's been plugged in for a while to try to reduce this.

Some phones bypass the battery when plugged in, but not all do. I know it's advertised as a feature of some gaming phones because graphics-intensive gaming is one use case where you'd want to use the phone heavily while plugged in.

Even then, some phones that advertise bypass charging are actually using a software-based implementation, and they can still end up with swollen batteries after being plugged in for extended periods.

Steamdeck lets you set your preferred % and the dock does pass through charging/power, which I love because that combo guarantees the longest possible life for the battery. I turn it back to 100% for flights, otherwise leave it as 80% at all times. Mine is almost 4 years old now but I don’t feel even a hint of battery degredation yet.

That's what I thought when I read this. It will probably destroy this battery very quickly.

But in other hand, it is probably a pain in the ass to remove the battery and do some workarounds to make sure the phone correctly behaves without it.

> It will probably destroy this battery very quickly.

'Very quickly' seems to be measured in decades from what I see

Most people I know have their laptop docked, either near-permanently at home or taking it between home and a desk with dock (so it's nearly always plugged in when in use)

The 'servers' I've had were all old laptops - yes, with battery (don't have to buy a separate UPS if one is already included). I've now also had two non-server laptops that were plugged into power pretty much all the time. I treated my first laptop perfectly: taking out the battery anytime I'd be in a classroom for several hours and it was already full enough (you know, back when sliding out your battery was possible in the first place), but I'm not noticing any faster degradation on the systems I treat poorly. I'll activate the 80% cap function where it exists (that is, in the latest phones and my work laptop's UEFI config panel), but the evidence of it being helpful has yet to materialize

I have read that studies show that charging to 100% causes degradation and I trust those more than random people's anecdotes (and I'm a random person), but I'm starting to wonder if I've maybe just misunderstood the study results. Maybe it's like how smoking increases your chance for some cancers but you might also be fine in the end. I see people with plenty of much younger and better-treated batteries that can't sustain literally 30 seconds of use whereas mine are reasonably close to the new state (some haven't had many charge cycles, just sat at a stressy high voltage all the time, which was indeed supposed to destroy them), and I don't know how to explain that otherwise

Some phones do too, it depends on their power management integrated circuit (PMIC) and driver. Though it's always better to physically disconnect the battery when not in use, as there is always a trickle current otherwise (most "spicy pillows" batteries are due to deep discharge, as far as I know). The best practice is to store batteries disconnected, at 60% capacity). In theory you could build a small circuit to sit in between the phone and battery to protect it, maybe I'll have a go at it.

stndef

What you can do, with some extra steps, is have Home Assistant installed (and have a Home Assistant server, I guess!) on the phone and use a smart power switch that's also associated with Home Assistant.

The phone's battery can be reported to Home Assistant, where an automation can be triggered to turn off power to the phone when the battery gets above a certain percentage and turned back on when it goes below.

Not the best solution, but certainly an alternative from messing around with trying to get the phone to work without a battery.

Couldn't you just have it charging on a time-regulated supply e.g. smart plug?

daemonologist

Most phones won't boot without the battery. Obvious workaround is to connect a power supply (and large cap) directly to the BMS, but in my experience most phones will shut themselves down when they think they've drawn more than the capacity of their battery, even if the voltage is still high. You can sometimes get around that by rebooting the device every couple of hours (and there might be a software/firmware fix in some cases?), but it's a lot less annoying to just accept a small risk of a house fire.

You could throw the phone in an ammo canister, if the wifi AP is close enough. When I was building hobby quadcopters, which requires several ~half-pound batteries that are a chemistry optimized for maximum power density, a lot of guys recommended steel ammo cans for battery storage.

Depends on how well the canister insulates it. Steel conducts heat fairly well; it'd get hot inside but I'd guess some airflow around the canister would probably keep it from getting hot enough to cook the electronics. (definitely don't take my word for it lol)

hnuser123456

Phones are very low power, likely just a slightly warm spot on the can that radiates, conducts, and convects the heat out. You could also use one of those peltier module phone coolers, to ensure the heat gets out of the phone and into the air faster.

Not really. No sign of a phone. Just a computer — same as what all other servers run on.

"My server runs on a computer with a form factor that is atypical for server workloads" gets a little closer to the heart of the article, but even then it seems the real meat of it is about Android, not the hardware (although that is mentioned too).

How about "My server runs on Android"?

This was based on "Apache Raccoon" https://sourceforge.net/projects/raccoon/files/raccoon/PS_1_... which was a port of Apache to Symbian, and a port of Python for scripting, complete with the ability to write multithreaded code (GIL excepted) using Symbian Active Objects.

alightsoul

FYI you can't do this on phones with locked bootloaders as well as the author did. you could use termux but if termux runs on anything lower than android 8 termux will be significantly limited and you will need postmarketos and maybe fix support for it. with termux, at best things will be slow without root, as the author mentioned rooting resulted in a speed increase.

without root, you also can't bind to ports on any android phone, and rooting often requires an unlocked bootloader and not all android phones support bootloader unlocking. You also need an unlocked bootloader to install postmarket os.

so without binding to ports you can't run a web server unless you run it through a proxy server which the author did, or containers at native speed on postmarket os because you will not be able to flash the phone with postmarket os if you have missing kernel syscalls on android nor root the phone for the speed increase on android depending on your android kernel version i assume.

so with android containers may or may not work without emulating x86, and without root chances are it will be slow specially if you are forced to emulate it as x86 because it turns out you have missing syscalls, nor root to make them faster if they exist on android. again no chances to install postmarket os nor rooting to make containers faster, without bootloader unlocking.

not all android phones can have their bootloaders unlocked unless you find an exploit. https://github.com/zenfyrdev/bootloader-unlock-wall-of-shame

I still think the best bang for your buck is an old desktop PC. Something like an i5 with 8GB RAM and an SSD will suit 99% of home server uses with capacity to spare.

Although I do see the appeal in getting unconventional hardware to do what you want, just for the love of the game.

My server is an extremely quiet Xeon workstation: unlike 1U servers, workstation are typically quiet. The good thing with a Xeon workstation is that it supports ECC RAM only and there are plenty used. For there's no market for used Xeon systems, so you can find stuff like 22-cores / 44-threads CPUs for $25 or something.

Some mod Xeon systems to use regular PC PSU like Be Quiet! ones and Noctua fans, etc. but my HP Z440 workstation is so quiet already I didn't need to.

In my case it's an headless server and is sits between the vacuum cleaner and the cat's food: there are literally only two cables connected to it, the power cable and the ethernet cable.

I can live with the footprint of one tower.

I run many VMs and containers inside those VMs: Git server, pastebin, NAS, containerized/VM-isolated AI agents, etc. but I don't need it to be up 24/7. I basically only need those when I'm working. So electricity usage ain't a big concern to me as it's more like running 8/7.

I don't feel like I'm commuting in a pickup truck: I feel like I have the perfect machine for the task.

Second hand SFF office PCs are super good for this. Machines like Lenovo Thinkcentre or Dell Optiplex.

Because there are so many of them (at least in Denmark where I live) they are pretty cheap and it's easy to get one with an I-processor.

My current machine's idle draw is also very low at 5-6w.*

*Based on some quick research it does seem that I was a bit lucky with mine, so I guess it's fair to mention that mileage may vary.

Buy a refurbished Xeon workstation with DDR4 RAM.

Slap your double NVMe expansion card, your two NVMEs and your 3 3.5" spinning rust in it. If the workstation doesn't come with a Xeon with lots of cores, just buy one on eBay for $25.

"Prior to deployment, smartphones must be processed to remove all but the motherboard, which contains the core compute functionality.

And they accomplished the author's first goal to run real GNU/Linux on the phones.

iPhone hardware wise is like an amazing alternative to rpi (way better hardware)

But the software makes no sense at all for a server, with screen locking due to inactivity and whatnot, not to mention energy and network priority is designed around a consumer use case on the move.

If you run Linux on it and take advantage from the Apple hardware like the light sensors and accelerometer - maybe it makes sense for measuring wave height, sky color, attached to a buoy or oil rig or something, you can even show it on a map due to its GPS. Assuming the oil rig has WiFi or a cell phone booster.

Idk though, maybe for something that important you just get the right stuff - cool hobby nonetheless.

I have similar idea of using my old Xiaomi Mi A1 as a server, but I have never actually done it. The author's first idea and mine was similar, replacing Android with PostmarketOS. And here is the difference, I was not brave enough to actually install PostmarketOS to my phone. Especially after looking at the Postmarket Wiki where not all features for my phone are flagged as supported.

In the end, I abandoned the idea and opted on purchasing an Android TV Box that has been installed with Raspbian for my home server. Sure it may not be as powerful as my phone, but it came with full blown USB that I can use to add any storage I want and it was cheap (today, it was approximately USD 11-12).

Cool project, but slightly better: before the rampocalypse I bought one of those aliexpress fanless linux boxes designed to be a router. I put a 32GB stick of ram in it and a 250GB SSD. I run opnsense in a virtual machine to serve as my home router and then I put the rest of my home server stuff on other virtual machines on that same box. It's still fanless/silent. It takes up zero additional space because it is my router. It would already be running 24/7 because it is my router so the additional energy usage of an additional VM is likely minuscule. The latency to my router is basically zero since it is on the same physical box. And it is using a real SSD so it has faster storage with almost certainly better endurance.

I thought this was going to be a rant about QR code menus.

Can you please tell me more? I'm trying to build a self hosted application (with Claude) so people can scan a QR code and place orders / send messages to the kitchen without having to flag down a server / waiter. It is supposed to save time and money for the restaurant and for the patrons and customers it is supposed to be more convenient. Do you not like this option?

JoshTriplett

Every system like that I've ever used has three fundamental problems:

1) It's optimized for the restaurant first, and the patrons second or not at all, and it shows.

2) Someone thinks "hey, we could sell ads on this", and now it's even more a piece of garbage. (This is also what happened with all the little kiosk-tablets on the tables at some restaurants. We just set them face-down on their screen and talk to a human.)

3) Most of them never anticipate unexpected problems. They might have an "order X" button, but they often don't even have a "call server" button. And when they do, it often doesn't work, because the other end isn't hooked up to something that gets people's attention.

The much lower-tech and more enjoyable solution I've seen used successfully many many times is a call button on the table. Press the button if you want service. Bonus if it has a "press this other button if you want to be left alone".

I always wondered how actually cheaper a QR menu is, compared for instance to an android tablet you set there or pass to the client so they order.

People immediately see the cost of a tablet, the issues with charging, building the app and updating the data, customers not understanding the interface etc.

Yet, they don't seem to grasp all of these are basically the same for a QR code: you're now maintaining an online service just for your restaurant. People still need to understand your site. You'll be dealing with their browser, extensions, languages etc. And you still need the QR code somewhere on the table, visible, explain that it needs to be scanned (by one person ? everyone ? do they need to keep the tab open ? etc.). These will all be costs, you pay either upfront by hiring experts to make the experience good, or on the go with crappy customer experience, your staff spending more time than needed working around the system and explaining it to your customers, and those not coming back.

There are super cheap and simplistic ways to deal with all of that, and I assume GP has seen many of these.

PS: The weirdest experience I ever had was someone at our table scanning the code, to copy/paste it on the browser on their personal profile (default was work browser). They missed a digit in the url params and ended up opening the order menu of a table at the other side of the restaurant, and just started ordering, then waiting for a pretty long time while the other table was dealing with the mess.

Notice that when someone grabs their phone, they're not just grabbing a web browser but also their personal entertainer. Besides chats, many people also have various apps trying to nudge them into engaging with it. I have never been in a restaurant without menu though, I just imagine that I'd end up on HN while contemplating what to pick out of sheer habit and muscle memory

Besides that, there are people who have no smartphone or an empty battery, can't use a smartphone (one of my grandparents can read a menu with a pocket magnifier, but a touchscreen phone is too cumbersome and so they don't know how to use that; another grandparent has memory issues and never learned how to use a smartphone), don't have signal (you need to provide WiFi), have an allergy and need to ask questions or ensure that some ingredient is really taken out, etc. I'm not against the option to order impersonally but a good kitchen communication system would go a lot deeper than slapping wetware with slopware

For whatever random reason, all the QR code menus where I live are implemented in a really, really shitty way: unresponsive, with huge latency, making it unnecessarily hard to make a choice. And good luck asking for a modification, like no mashed potatoes please or anything like that.

Using QR codes to not having to talk to a human and to "optimize" humans out of the loop in a restaurant sounds like a great scenario for an episode of black mirror.

QR code menus are one the shittiest experience people going to a restaurant to enjoy a meal can have.

Not exactly the same usage but I run a headless Chromium with Puppeteer on a Raspberry Pi 4 at home for some light ("ethical") web scraping (as a residential IP is essential sometimes to bypass Cloudflare).

A real html page maxes the cores easily but it works. Keeping the pages open instead of closing / reopening tabs helps.

For reference I tried running it in a container inside my low end Synology DS223j but any container running, even doing nothing, ruins disk performances, weird bug.

Keeping it plugged in like that is going to harm the battery.

That and the fact that my Xiaomi 12 runs USB 2.0 ....

I'm stuck running stuff on MacBook at night when I don't use it because of that.

Just a heads up, proxmox now supports ARM, so with the authors setup, it could potentially run Proxmox along with LXC for containers.

LXC does provide a security boundary, more than Docker but less than a full blown VM.

Nice writeup but use legacy phone is really need to do some tuning and hacks, but that's fun to do if one like it.

For me I have a 24x7 running intel gen 11 nuc, i am lucky to get it installed with 32G memory and two NVME disks years ago and cannot image add those memory and NVME disk with much higher price

Just run some docker and VM on that, use cloudflare tunnel or tailscale funnel if you want to expose some service to the wild internet

I recently even find a pixel 5 and passthrough it to the openclaw VM on that nuc, let it browse the X to find some posts and relax me from doom scrolling, though seems timeline still bad and no much valued post find.

I thought about this a few times but the flash storage is a bit sketchy for running a database, I am worried it can die. Tho android does have sqlite built in and works fine.

kllrnohj

9 hours ago

Any storage device can die, that's why you have a robust backup system, right? Right...? :)

But the flash storage in a phone is going to be the eMMC variety which typically means a proper controller and TLC NAND. Not as robust probably as a "proper" SSD/NVME, but a lot more durable than most micro SD cards. And it'll have health indicators.

lucb1e

9 hours ago

Just because it's a database doesn't mean it does more write cycles on the flash cells than storing regular files would cause it to. Anytime you change something, it writes either a file, or does an update/insert query which causes a file write. In both cases you've written a few bytes to disk, doesn't really matter what the underlying system is (not majorly anyway, surely one solution will turn out to be some % better than another and cause the average phone's storage chip to last 30 years instead of 40 under some defined typical usage pattern)

You can also just insert an SD card to do the write-heavy operations and swap it out when it wears out (you make backups, right? :D)

If your phone supports being USB host you can try USB splitter dongle and attach external SSD drive to it.

Also if your phone has SD card slot you can try "industrial" SD cards. They are small in capacity but ideal for write load.

That's a test of the software more than the hardware. I run a lot of stuff on low-powered hardware and the main problems are when the software allocates a ton of memory unnecessarily (Java software is usually the worst offender) or does a million things for each request that are either unnecessary or duplicate.

Any efficient blog software will handle HN fine on anything that you can call a smartphone, so like maybe not a Nokia with GPRS and 6MB on-board storage, but something like the Samsung S2 from 2011 that basically shipped as a Linux box -- just need to adb push ARM binaries for PHP and a webserver

The main difference is that Camoufox doesn't have an iOS 6 client. Surf is built around that client experience: omnibox, tabs, history, uploads/downloads, touch input, and audio/video streaming targeting 60fps. So Camoufox is great for running browser instances on a VPS, but it doesn't really replace what Surf is doing for an old iPad.

Sounds legit, circumventing the locks people are trying to add to their properties in an attempt to keep costs down and the service available for people that are actually trying to use the service rather than bots roaming around. Really happy for you that you managed to run ten of those. Not a nuisance at all.

That would be a fair point, but I don't see that in the source. The article's first mention of Surf is a link to a previous article <https://seg6.space/posts/resurrecting-ipad-mini/> where the motivation is mentioned:

> I wanted to turn [the old tablet] into a smooth, distraction free reading device, so I [got root and] transferred a few books with iFile and had exactly what I wanted [...] until the reading workflow left the book. \n\n Reading is not really offline anymore. Finding articles, checking references, downloading PDFs, opening links, and asking an LLM about something confusing all happen on the web. [...] [The ancient Safari engine can't provide] JavaScript, CSS, media, and browser APIs expected by current websites [and Apple didn't allow third-party engines.] [...] Since I was on vacation, this also felt like the perfect pet project to hand to an LLM and see how far it could get. Out of that experiment, Surf was born.

The point seems to have been getting iOS 6 to run a modern browser, which was experimentally built with an LLM, not so much have LLMs roam and masquerade themselves on the web via it

logicallee

(not OP). okay here's something that's not the same old post. I don't walk around with it in a backpack though:

I asked Claude to set up Twilio (a phone API), and after setting everything up for it, now I can give my Claude agent instructions in any format where I have access to it (such as our Jira, by email, or when I'm writing a prompt by hand in Claude Code) to call me if it gets stuck or has any questions or needs anything from me, or to call me when it's finished.

so now I sometimes get to relax at home and get a call where Claude tells me that I have a Jira ticket that needs me to answer a question. so I open up Jira, answer the question, and go about my day.

(I also have it call me to remind me about appointments and requires me to press a key to acknowledge it, so that I definitely don't miss the call and confirm that I got it - I did this because I was constantly missing reminders and calendar appointments.)

So, while my server isn't literally a phone, it does call me when it has a question and to remind me about my appointments.
