is rust so much better than C language

lsatenstein — Tue, 03 Nov 2026 22:15:49 GMT

I have studied Rust, and it is definitely not better for the programmer than C.
What you say?
Rudy's claim to glory is not at all in algorithm solving, but in doing type checking agreement, ownership management and strong type checking

But the C compiler (gcc 16.x) or clang compilers do likewise AND as accurately. And where there is possibility of source code confusion, warnings are issued.

For the amateur programmer, Rust will protect him from stupid mistake, mistakes that might get past a c programmer.

The modern C compilers do type checking
, strong length checking, and const/volatile checking.

The experienced C programmer with two years experience does in C code, what the rust programmer does.

Here is my conjecture.

In industry, repair costs of distributed code is expensive. Before code gets released, strong quality code walkthrough and function testing is performed.

I believe that an experienced C programmer can deliver a clean complex Function or program in less time than can an experienced Rust developer.

Here is what favours Rust. For 2 programmers, one.for rust and one.doing c, the rust program is less likely to crash.

But there is no guarantee that the function programmed is accurate and will do what the requestor intended.

I chose C vs Rust, and not Python, java, or lisp vs Rust.

Don't put Rust fully ahead of other languages

Possible super deal or a scam?

Not sure if I'm getting hosed or not, but I made a purchase of 2 8GB Raspberry Pi 5's for $24/FS. New items from a Newegg seller. I figured at that price it was way too good to be true so I didn't order more. But best I can tell they've been shipped and the item was removed from the Newegg site, at least it's showing red "out of stock" notes now. I wasn't sure enough about it to invest any more, but in hindsight I probably should have. I was tempted to do it today but just saw the aforementioned message. All the other versions are massively more money. If indeed these are RP5s w/8GB, I'll be thrilled but this'll be one of those cases I really wish I'd ordered a couple more... I ordered a dual sata hat, 2 power supplies, 2 cases and 2 fan/heatsinks, and didn't have $80 in the whole mess. It's possible these are clones (not that I care as long as they work). Fingers crossed they are what they say. Worst case is I have to buy 2 4GB versions at the regular price since that's really what I needed.

Businesses use my first name as my last even when they should know

marko — Tue, 03 Nov 2026 15:25:02 GMT

I have an unusual german name, so when I give a name for something like a take out order, I just give the first name to make it easier. My first name is also reasonably common as a last name. When they call the order it's completely understandable they use my first name I gave and "Mr" on the front since they don't know. If I had given "Joe" which is not a common last name, they'd probably just call out "Joe".

But other entities like my dentist know my full name but insist on calling me "Mr " on the phone, like just now on a appointment reminder. That seems pretty strange to me, they have a CRM software right there when they call, probably showing my appointment and full name.

So how does that happen? My only guess is that software is showing the last name first like a Contact list would and people don't pay attention and flub the first name as the last. What's odd with that explanation is this isn't just happening at one place but several. I'm curious if others are seeing this going on, I've only noticed this in the last five or so years.

Just Reminiscing

Kobuck — Wed, 21 Oct 2026 19:58:29 GMT

Building an ARM SBC today is a remarkably accurate parallel to 2000's desktop Linux builds.
If you look at Fedora Core 1 (released in 2003) or Red Hat Linux 9, tinkering with a PC back then felt almost exactly like buying a cheap Rockchip or Allwinner ARM board today.
The structural hurdles are identical:

1. The Fight with Monolithic Kernels & Custom Drivers

Today, if you buy a random ARM SBC, you often can't just boot a generic Linux ISO. You have to hunt down a specific fork of the kernel containing custom device trees or proprietary drivers for the board's HDMI out or Wi-Fi chip.
Back in the Fedora Core 1 / Linux Kernel 2.4 era, x86 PCs felt just as fragmented. Hardware wasn't truly universal yet. If you bought a new Winmodem, a Sound Blaster card, or a cutting-edge AGP graphics card, you couldn't just plug-and-play. You had to download the tarball, open a terminal, configure your kernel flags (make menuconfig), and compile a custom bzImage with monolithic driver support because loadable kernel modules were still prone to breaking.

2. Upstream vs. Vendor Kernels

With modern ARM SBC's you constantly stuck choosing between a stale, heavily patched vendor kernel (like an ancient Android-based Linux 4.9 kernel) that supports the board's hardware, or a clean, "mainline" upstream Linux kernel that lacks full hardware support but has modern security updates.
In 2004, Fedora Core 2 made the massive jump from the stable Linux 2.4 kernel to the bleeding-edge Linux 2.6 kernel. It brought radical architectural overhauls (like switching from XFree86 to X.Org for graphics). Doing that upgrade back then felt exactly like trying to jump an ARM board from an old legacy OS to a modern mainline Debian or Arch deployment ( or in my case Fedora builds ) �something always broke, usually your display server or your file system.

3. The Lack of Unified Bootloaders

With modern x86 PCs, UEFI just works. It searches for an EFI system partition, grabs a file, and boots. ARM SBCs don't have a unified BIOS/UEFI standard; they rely on flashing custom U-Boot binaries to specific sectors of an SD card, alongside custom partition tables. Its the reason I'm reaching for Mainline uBoot EFI in my builds.
In the early 2000s, managing GRUB (or LILO!) on x86 was just as precarious. Messing up your partition geometry or installing a second operating system would routinely obliterate the Master Boot Record (MBR), dropping you straight into a terrifying, unbootable grub> rescue prompt.

4. Storage Bottlenecks

Flashing a 4GB raw image onto a slow MicroSD card and watching an ARM board chug during its first boot resize script is a painfully familiar cadence. In 2003, we were installing Fedora Core from a stack of 3 or 4 physical CD-ROMs onto slow IDE hard drives (spinning at 4200 or 5400 RPM over ribbon cables). A full system installation or a package compile took hours of listening to the hard drive thrash.
Building a Linux machine back then meant you were intimately aware of every single layer�from the boot sector to the compressed bzImage, right down to the custom-compiled display drivers.

Do you remember the pain of dealing with dependency hell before yum and dnf?

Alternative Energy For The Home

Dan — Sat, 17 Oct 2026 17:14:02 GMT

As suggested in another thread, do you rely on the mains, (shore power) alone, or do you have / run alternative energy sources in or for your home?

I think most of us who live in non-urban areas likely have generators and/or power stations for outages, but have you invested in any kind of solar for emergencies, or everyday power demands?

Out here, we experience outages often enough (which can run into many hours), that I do keep a decent sized (9000w surge/8400w running) gasoline/propane/NG multi-fuel generator on hand -- and serviced -- to keep the freezers from failing during an outage. That just seemed wise, and I was willing to settle for that until the EPA and ERCOT achieved concurrent max-dysfunction and allowed massive shortages/outages/rolling blackouts during the Polar Vortex of '21, (and managed to kill 147 Texans in the process). The following spring a wicked little neighborhood thunderstorm took specific, accurate and devastating aim at our local substation -- killing it quite dead. They had to truck in a full mobile replacement from another coop. That took all day and most of the following night.

Long story short, there are now also three power stations in the house running in fall-through mode. Two are keeping the freezers supplied, and one is here in the office feeding the computers and internet. The Radio Station is still on AGMs and computer UPS style backups, but as soon as practicable, that will get shifted over to LiFePo4. One of these days I need to get another power station installed to keep the active septic system energized. All of those are set up to run default on the mains, but if that fails, they are also set to be supplied by a pair of 460w solar panels.

Before we get into the deeper cold of the season, I have plans to mount two more panels on the other end of the house to eliminate the potential need of rolling power stations around the house. The small ones carry easily. The big one ... not so much.

Just How "Smart" Are You?

Dan — Fri, 16 Oct 2026 03:28:31 GMT

How deeply have you plunged into the Marvelous Mysterious Magical Land of the Hyper-Connected, massively surveilled?

I didn't include a selection in the poll for the Smart Phone, because that's pretty much assumed (and the most egregious) these days. I also suspect I have missed several devices and categories. But for now, I'm curious how far an obviously very techno-savvy community has delved into the perhaps defining (for better or for worse), technologies of the age.

(Unless I screwed up when I posted this), go ahead and tick all that apply in your particular situation.

Hypothetical new PC plan

Wayne — Thu, 15 Oct 2026 03:02:14 GMT

I have a Lenovo IdeaCentre with a lame power supply which I've upgraded as far as it will go. It's based around an 8 � AMD Ryzen 5 3400G

X-Plane runs OK but with a limit of 4Gb VRAM on the AMD Radeon RX 6400 GPU I'm missing a lot of detail. The max TPU for the GPU is 75W!

I'm thinking of downgrading it a little to 16Gb RAM (from 32Gb) and two 1Tb SSDs down to one 256Gb NvME (system) and one 500Gb SATA
SSD (/home) and giving it to 'er indoors with Linux Mint. It'll still be a very good system!

So, I'll be left with:

TEAMGROUP DDR4 2666MHz PC4-21300 32GB (2 x 16GB) Desktop Memory Elite Plus Series

1Tb WD Blue NvME (system/data) and one 1Tb Crucial SATA SSD (X-Plane 11 & 12)

AM4 is still quite usable these days, so I will only need:

AMD AM4 CPU w cooler
AMD GPU with at least 8Gb VRAM (preferably 12Gb)
AM4 motherboard
Case with included fans
Power supply at least 700W

RAM & storage is so expensive I feel I'll get better value by recycling! I want to keep it under 100,000 yen ($650)

Or am I totally nuts?

Song lyrics

glennzo — Fri, 09 Oct 2026 22:21:17 GMT

In my opinion, some of the most profound rock lyrics ever.

Quote:

The song is over
I'm left with only tears
I must remember
Even if it takes a million years
The song is over
The song is over
Excepting one note, pure and easy
Playing so free like a breath rippling by

Nuthin' But ... Whoops! Not Even a Cricket

Anyone using Yahoo.com's email and black band for open applications

lsatenstein — Mon, 05 Oct 2026 13:08:34 GMT

When I select the mentioned, I have to work to get a list of topics (click all) but it is forgotten if I open any message.
When I open a message I have the top and bottom third blocking the message contents. That is....
I have a 1/3 screen window.

Is this normal, what do I have to do to restore normalicy to yahoo.com interface?

Second, The band at the top is pitch black, I have that problem with Gnome 45, Again, I have to search for the buttons hidden in the black band. Is that band a Gnome 51 feature

I am ok with Google's gmail, but its a pita if I want to switch over. The world knows me as being with Y for 2o+years
