linuxlizard··on Show HN: The Montana MiniComputer
I did my MS-CS in Bozeman. I'm super excited to see MSU on HN FP as well! Very cool!
linuxlizard··on Supreme Court Gives Doge Access to Social Security Data
My college classes used to post grades, on paper, taped to the wall, listed by SSN.
linuxlizard··on Micro Wheeled legged Robot
I want to hack this to drive around the office and find an AP based on signal strength. Bloodhound mode!
linuxlizard··on I asked police to send me their public surveillance footage of my car
Root word comes from the Greek mythological giant. https://en.wikipedia.org/wiki/Argus_Panoptes
linuxlizard··on Ask HN: What less-popular systems programming language are you using?
I'm a big fan of Ada. I first encountered exceptions in Ada. When I first saw Python, way back in version 1.5, I was happy to see exceptions.
linuxlizard··on South Korean president declares martial law, parliament votes to lift it
California.
linuxlizard··on Landowner Sues After State Searches Property Without Warrant or Consent
Are the private schools forced to take any students? Or can they cherry pick just the best students? Do they reject anyone that needs an IEP? Public schools are legally obligated to provide an education to anyone, no matter how much trouble they cause. If these private schools take public coin, they should be required to follow the same laws.
linuxlizard··on Understanding how bureaucracy develops
>When you treat every negative outcome as a system failure, the answer is more systems.

Holy crap, I'm going to save that quote forever. I have a co-worker who treats every line of bad code committed as a reason to add ever more layers to CI. Yo, we caught it in testing. There's no reason to add another form we have to fill out.

linuxlizard··on Ask HN: Why haven't we miniaturized the Ethernet RJ45?
That makes sense. Phones would drive smaller USB and laptops likely drove smaller DisplayPort.
linuxlizard··on Ask HN: Why haven't we miniaturized the Ethernet RJ45?
That does make sense. Ethernet is easily replace by WiFi. There's no easy replacement for USB (can't charge a phone over Bluetooth (yet)).
linuxlizard··on Ask HN: Why haven't we miniaturized the Ethernet RJ45?
Crimping our own cables is more common in data center or IT. Normal people wouldn't cut their own cables. I've given up cutting my own cables for home use (fixing busted heads) because it's easier to just grab a new cable.
linuxlizard··on A novel channel contention mechanism for improving wi-fi's reliability
There's no laws about it. It's mostly a "handshake agreement" enforced via the WiFi Alliance. You go through the WFA certification process to get the "WiFi Certified" sticker. https://www.wi-fi.org/certification

Usually large vendors try to do the right thing.

linuxlizard··on Attacking UNIX Systems via CUPS
I wrote printer code for 10+ years. I appreciate how hard the technical problems are but vendors make it so much worse. I loathe printers. Printers peaked with the LaserJet III.
linuxlizard··on Jeff Bezos' management rules are slowly unraveling inside Amazon

Or just me.

linuxlizard··on CrowdStrike Update: Windows Bluescreen and Boot Loops
Crowdstrike also has an Ubuntu Linux version. We're required to install it at work.
linuxlizard··on The saddest "Just Ship It" story ever (2020)
I came to work over a vacation to fix a critical customer issue. The company rewarded me with a $50 gift card.
linuxlizard··on Reverse engineering ESP32 Wi-Fi driver: the road ahead
Decompiling the microcode blob might run afoul of intellectual property laws. A clean room implementation needs to be done without reading any of the product's actual code.
linuxlizard··on Opening Windows in Linux with sockets, bare hands and 200 lines of C
When I first started using UNIX (Ultrix on a DECStation), I was floored by the wizardry of "hackers" sending me email from Santa Claus. Mind blown!
linuxlizard··on Embezzlers Are Nice People (2017)
>Yeah, I wonder how the EU will deal with people who use that law to hide evidence of their misdeeds...

Here in the US, we elect them to public office.

linuxlizard··on A. K. Dewdney has died
I also read _The New Turing Omnibus_ as a young CS student. I really enjoyed reading about all those different areas of Computer Science.
linuxlizard··on HP Tries Desperately to Make 'Printer as a Subscription' a Thing
Depending on your use case, Cam Scanner (I'm on Android), works very well for the occasional document picture.
linuxlizard··on Scientists Developed a Tool to Reveal Who's at Risk of Burnout, and It's Free
Out of 10, right? Out of 10?
linuxlizard··on Scientists Developed a Tool to Reveal Who's at Risk of Burnout, and It's Free
We had that same burn-out measurement tool in HP-UX, SCO, and SunOS!
linuxlizard··on Framing Frames: Bypassing wi-fi encryption by manipulating transmit queues
An old hub (not switch) does exactly that: all traffic forwarded down each port and I can see what everyone was doing. Even with a switch, a misbehaving device can cause all sorts of havoc on an Ethernet network. 802.1X is supposed to provide port security but isn't used often. Anyone could plug into a wall port and get access to a corporate network.
linuxlizard··on Framing Frames: Bypassing wi-fi encryption by manipulating transmit queues
He's forcing me to work hard, dang it! I'm being forced to study WiFi carefully and learn his (really amazing) tools to fix these issues.
linuxlizard··on Framing Frames: Bypassing wi-fi encryption by manipulating transmit queues
Wi-Fi has the same challenges as if someone just tapped an Ethernet cable. (Except the Ethernet line can't be sniffed from the parking lot.) The amount of unsecure traffic on a basic Ethernet network makes Wi-Fi security slightly better.
linuxlizard··on Framing Frames: Bypassing wi-fi encryption by manipulating transmit queues
I swear Mathy Vanhoef has dedicated his life to making my life miserable. Every time he finds these wifi security problems, we get to spend weeks/months integrating and testing vendor patches.
linuxlizard··on Google Cuts Jobs in Engineering and Other Divisions
Look at Boeing.
linuxlizard··on Developer Productivity for Humans: Software Quality
I know it's ridiculous, but I will use my own time to work on some problems that officially we're not allowed to fix. I make that issue my hobby project and use my time to learn some new tool/technology (that looks good on a resume). For example, right now I'm learning Rust to fix [a hairy build problem]. Taking on the problem gives me back some that developer motivation. Using it as a learning opportunity makes me feel like I'm personally growing.
