mackman··on Tell HN: Uber sold my email address
If you email really was just uber@domain then this could just be dumb luck. Spammers try permutations all the time.
mackman··on Mercedes-Benz previews its operating system MB.OS
I’d be surprised if this isn’t just another Android fork.
mackman··on Eggspensive
Weird, it looks like Massachusetts is the only state where every store has the same price. I wonder why MA is special in this regard.
mackman··on A Docker footgun led to a vandal deleting NewsBlur's MongoDB database (2021)
My guess is they were going to attempt point in time recovery by replaying transaction or relocation log after the snapshot and stop it before the drop. Unless they made a mistake.
mackman··on Ask HN: Is it just me or is 5G strictly worse than LTE?
I worked on a team that prototyped the “watch the game on your phone at the game” using WiFi. Nobody used it. That isn’t going to be the killer app either.
mackman··on Time to redefine normal body temperature? (2020)
In the afternoon my son’s temperature is closer to 99.5. Of course I never measured it unless I thought he was sick and confirmation bias led me to believe he was feverish. I finally started checking it in the afternoon when he seemed well and realized he was just always warm in the afternoon and all that worrying about his “fever” was pointless.
mackman··on Ask HN: Are you a “lifer”? If so why?
I think the most important thing is that the work stays varied enough to be interesting in the long term. If you aren't able to move to new projects you'll eventually get some combination of bored, restless, and burnt out. Then it might be time to reboot your career inside the company (if that's something they make easy to do) or you might find yourself ready to move on.
mackman··on FTX faces potential hack, sees mysterious outflows totaling more than $600M
Shifting by two is dividing by four. Not so easy, after all!
mackman··on ImageSharp leaving the .NET Foundation due to licensing change
Just because you have a license to use software doesn’t mean you have a license to change the license.
mackman··on pigz: A parallel implementation of gzip for multi-core machines
Hey Eric! Hope you’re well!
mackman··on Why adults still dream about school
This seems correlated to symptoms of imposter syndrome. I stopped having the dreams around the same time I started to get over imposter syndrome. Only took 18 years.
mackman··on The dumbest way to solve a maze [video]
Back when I worked in the video game industry I built a tool to find places in the collision mesh where objects could fall out of the map. It worked by just doing millions of ball simulations. Distributed the job with one sector per core to every developer machine at night. Worked great!
mackman··on Goodbye, shitty Car extends Vehicle object-orientation tutorial (2011)
Long ago in the games industry I was applying for a position at a studio. Didn't end up getting a job but a friend did. A few months later he was bemoaning their terrible code base which included a car class that inherited from wheel four times.
mackman··on Barriers to Business – How cities can pave a path to entrepreneurship
"But officer, you can't close me down... the blockchain says I took care of the rat infestation!"
mackman··on Why can’t we remember being born or our first words?
We moved when my baby was one year old. Both our old and new houses had stairs he would scoot down backwards on his belly. Once right after we moved he would reach the bottom and keep scooting backwards on the floor. He pretty clearly was thrown off by the fewer steps in the new house.
mackman··on Why can’t we remember being born or our first words?
I remember visiting my moms house in my 20s and seeing an old dresser I had as a baby. I immediately had a flash of the feeling of chewing on the drawer handle. My theory is that the memories are there but they just don’t make a lot of sense to us once we start to use language for storage and recall.
mackman··on Teaching GPT-3 to reverse words
I feel like this is a given in a lot of sci-fi I read. "Jokester," an Asimov short story, is premised on people called "Grand Masters" who know how to ask the right questions of Multivac, the globe-spanning supercomputer that appears in a few of his stories.
mackman··on Researchers demo Bluetooth relay attack against Tesla
Can someone please help me understand how using a relay device defeats proximity detection by time of flight? It’s not like the relay device can talk to the remote device faster than the speed of the original signal.
mackman··on Over $1.2B in Bitcoin reserves remains unaccounted for by Luna Fdn. Guard
My understanding was he was offering 20% returns on investments and it seems it was paid for by new money coming in propping up the currency despite the dilution caused by interest payments. That sounded like a Ponzi scheme to me.
mackman··on Over $1.2B in Bitcoin reserves remains unaccounted for by Luna Fdn. Guard
I assure you the foundation won’t make a profit :-)
mackman··on Over $1.2B in Bitcoin reserves remains unaccounted for by Luna Fdn. Guard
The very first thing I though of when I heard about the bitcoin reserves was “that’s a great cover story to hide extracting more solid currency out of an obvious Ponzi scheme.” And low and behold it can’t be accounted for. This is my surprised face.
mackman··on The games Nintendo didn't want you to play: Tengen
Yeah this finally clears up why I have memories of a completely different NES Tetris game than I could find any reference to online. I thought this was one of those Mandela effect situations.
mackman··on Open Infrastructure Map
Anybody know how much trouble you’d get in cross country skiing or snowshoeing along the routes of these big power lines? They clear all the trees and brush and it looks like it would be a great alternative route to get around in winter. All those no trespassing signs have me spooked.
mackman··on The Strange, Unfinished Saga of Cyberpunk 2077
There is paid overtime for some employees. Including engineers. Instead of a project completion bonus for other employees. It’s a bit of a wash.
mackman··on Ask HN: Why is Docusign a $50B company?
You might have been on to something. Today it's a $30B company.
mackman··on Arm AArch64 Adds Memcpy() Instructions
I remember implementing memcpy for a PS3 game. If you were doing a lot of copying (which we were for some streaming systems) it was hugely beneficial to add some explicit memory prefetching with a handful of compiler intrinsics. I think the PPC processor on that lacked out of order execution so you would stall a thread waiting for memory all too easily.
mackman··on For precision, the sapphire clock outshines even the best atomic clocks
Isn’t Doppler shift a frequency shift, not a phase shift? Or is it both?
mackman··on For precision, the sapphire clock outshines even the best atomic clocks
Don’t you just need to determine the scaling factor and now you have precise and accurate?
mackman··on A street snack that has baffled botanists
Have you looked into any processing steps between harvest and serving? I am curious if they are soaking/fermenting/acidifying it in some way which would account for the differences described from straight agave.
mackman··on Bye CUPS: Printing with Netcat
My first introduction to the internet was downloading Magic the Gathering card lists as postscript files via FTP and then FTPing them to a postscript printer. Would have been 1994 and they were some sort of Sun machine at LMU. Internet has been all downhill since then.
