linuxlizard··on Ask HN: Who Wants to Be Fired? (June 2022)
"What is it with you kids? Every other day it's 'Food, food, food'" -- Bender
linuxlizard··on Why unprecedented birdflu outbreaks sweeping the world are concerning scientists
My bird feeder does pretty well. https://morebirds.com/collections/caged-squirrel-proof-bird-...

linuxlizard··on You and the planet need a heat pump
I can't remember, sorry.
linuxlizard··on You and the planet need a heat pump
I _just_ ripped out our ~10yo heat pump at home, installed a fully gas furnace. The accursed thing was so loud and it sat right outside my office. When working from home over the winter, it would fire up and drown out any conversation in my office. I gladly ripped it out and danced on its grave.
linuxlizard··on Linux Developer Laptops: Dell's Precision 5500 series reigns supreme (2019)
I've been having very good experiences with my Lenovo P15v dual booting Fedora/Windows. Intel graphics aren't speedy but are reliable. Absolutely gorgeous 4k screen. The usual nice Thinkpad keyboard.
linuxlizard··on Akamai to Acquire Linode
As another long time user of Linode, I have had nothing but good experiences with them. I hope their quality stays up.
linuxlizard··on Signal users can give a recurring monthly contribution
Please continue to contribute to Wikipedia. It's one place in the internet I can go and not be bombarded with ads.
linuxlizard··on Record lifetime for a bubble
But this time is different!
linuxlizard··on Wrapping Up 2021. Leaving C++
I wrote a toy Ada compiler for my master's thesis. It's a very fun language. I miss using it. I was attracted to Python because of exception handling which I learned from Ada.
linuxlizard··on Example Domain
I have a .com domain with 'test' in the name. I was mildly DNS spammed because Microsoft admins would create that thing with test in the name. I'd get 10-20 DNS packets a day. I moved it to an external DNS provider just to give my logs a break.
linuxlizard··on Ask HN: Which tech stack is the most fun?
I loved Tcl way back before I switched to Perl. So cool seeing Tcl and HTML combined like this!
linuxlizard··on Overdue library book returned more than 110 years later
Nice to see my home state/town making cute national news for a change (as opposed to our usual cringe-worthy coverage).
linuxlizard··on If Apple keeps letting its software slip, the next big thing won’t matter
This is some great stuff. Thank you! I'm definitely going to lean into chocolatey. My daily driver is Linux but I still need a Windows machine around.
linuxlizard··on Image file formats that didn’t make it
You should take a look at tiff (also on their list for some reason). I used bmp in my imaging work because it's lossless and uncompressed (I got tired of waiting for 500M png files to open). But tiff is quite simple to understand and is a little more future proof than bmp.
linuxlizard··on Image file formats that didn’t make it
When I was doing imaging, tiff was my go-to. It's uncompressed so huge images would pop open quickly (compared to loss-less png). I could store 16-bit CMYK images in tiff which no other format (except maybe PSD) would do.

Several years ago, I attended a talk at an imaging.org conference where the presenter, an archivist from the Smithsonian, described how they used tiff in their work.

linuxlizard··on Moiré No More
Another great use of an FFT and filtering. https://www.edn.com/buenos-notches-the-filter-wizard-vs-the-... Filtering out vuvuzela noise. Same sort of idea, targeting the frequency peak of an obnoxious interference.
linuxlizard··on Awk: The Power and Promise of a 40-Year-Old Language
I think I remember reading somewhere Larry Wall was inspired to create Perl in order to combine awk+sed functionality. He was sick of awk+sed being almost powerful enough to do what he needed. (I can't find a reference to this though.)
linuxlizard··on Awk: The Power and Promise of a 40-Year-Old Language
I use awk to auto-generate C header files from other header files. I work with $vendor's huge complicated kernel driver codebase. I need small pieces of $vendor's interconnected header files in order to make kernel calls to their drivers without pulling in all their code.
linuxlizard··on Intel to Adopt SiFive's New High-Performance P550 RISC-V Cores with 7nm Platform
Intel sold off their X-Scale/StrongARM to Marvell in 2006. https://www.theregister.com/2006/06/27/intel_sells_xscale/ I was with Marvell at the time and we were pretty excited to get it.
linuxlizard··on Observable Plot
Ditto. I'm learning D3 and the examples and the d3 source itself has been a boon to a new learner like me.
linuxlizard··on Two UK Broadband ISPs Trial New Internet Snooping System
Why didn't they just do what the US Gov did? Snoop but not tell anyone. Certainly would have saved them some grief. https://en.wikipedia.org/wiki/NSA_warrantless_surveillance_(...
linuxlizard··on How does your programming language handle “minus zero” (-0.0)?
Latitude / Longitude coordinate as floating point.

https://gis.stackexchange.com/questions/211796/if-degrees-is...

I made the above post due to a bug in the GPS on our routers. We had a customer close to the meridian in England.

http://www.thegreenwichmeridian.org/tgm/articles.php?article...

Western hemisphere is negative longitude, eastern hemisphere is positive. If your degrees are 0 (within ~100km? I can't remember exactly), then you still need to know if you're east or west of the meridian.

linuxlizard··on Giving Ada a Chance
I very briefly encountered MUMPS in grad school and its eldritch horror has remained seared in my brain.
linuxlizard··on Giving Ada a Chance
I did Ada back in university. I wrote a toy Ada compiler for my master's thesis. I was so enamored with Ada's exception handling at the time! When I discovered Python and its similar exception handling, I jumped onto Python in a heartbeat.
linuxlizard··on Giving Ada a Chance
I enjoyed Fortran/FORTRAN. Is a nice succinct language.

"Lovecraftian hieroglyphics of Fortran" <-- the author never programmed in Perl, I presume.

linuxlizard··on 50 Years of Pascal
Was hoping someone would mention Ada. It's the most Pascal-y of all Pascal's children. I enjoyed my brief time doing Ada. I should look at Nim.
linuxlizard··on Fry's Electronics is closing all stores
I liked CompUSA. The employees I interacted with were great. Boise, ID. Was sad when they closed.
linuxlizard··on The Dunant subsea cable
if this were reddit, I'd be throwing gold at you.
linuxlizard··on I'm tired of this anti-Wayland horseshit
Same here. I still remember the days of XF86Config. X.org was a great step up. And now I've never even noticed the transition to Wayland. Everything still works great.
linuxlizard··on Ask HN: Who is hiring? (February 2021)
Cradlepoint | Boise, ID and Los Gatos, CA USA | Embedded Linux, Web Development, SaaS, DevOps | https://cradlepoint.com/about-us/careers/

At Cradlepoint we build embedded Linux routers which highly integrated carrier network support as a failover solution. We use a large web software stack to manage thousands of routers in the field. Retail location will use our routers as a failover to cellular if their primary DSL/Cable goes down. We also build vehicle mounted routers. City buses use our routers to provide customer Wi-Fi. FEMA uses our routers in the field to provide Internet in disaster areas. We're also investing heavily in the new 5G and FirstNet rollout.

I don't know what the status is of hiring remote. Please contact our HR folks.

Disclaimer: I'm not involved in hiring. I'm just a firmware engineer who really enjoys working here. On the firmware side, we're a lot of C and Python.
