I built things that you probably see and use every day, and changed the world a little.

kw71··on Women Who Code Moves Global HQ from SF to Atlanta with Help from Home Depot
And away from the toxic social atmosphere in California too, which seems to be the source of a lot of the workplace misogyny complaints and even never-ending dating scene of doom that I hear about.
kw71··on Archiving C64 Tapes Correctly
Also longer tapes could be affected more by stretching.

For computers they sold cassettes in short lengths such as 15-minutes.

The Datasette had a digital interface to the computer. This and the known calibration went a long way to help it.

Yeah I didn't think so.

I am having trouble understanding and believing.

How did you get an ostensible power terminal (for pull up) and two terminals for MiTM (input and output) from two terminals? Assuming a situation where there are other pullups on the wire, how did you assert the low state (short to ground) without a connection to ground?

kw71··on LED Strain
This is not that. This is multiplexing and the purpose of it is to save i/o wires. If you film it with a high speed camera you will see something like one digit being lit at a time.

I'm glad it works, but this is the exact product I thought he was trying to avoid buying. While a lot of thought and development probably went into chickenguard, it ain't cheap.
kw71··on Charter, Comcast don’t have First Amendment right to discriminate, court rules
I think the shopping channels pay for carriage, and they are popular beyond my wildest expectations - if I did anything to make one of them go out there would be calls complaining about it immediately!

Like I said above I retired from this business a decade ago but I have a hunch that IP is going to be a better experience over docsis or any other broadband link. I don't see much complaining from fios/uverse customers, and I worked independently on a metro WAN iptv development in moscow, which worked pretty well when the residents had fast-ethernet connections, once we got the infrastructure to handle all the multicast traffic.

Well this isnt so much the case anymore with switched networks. This was a thing 10 years ago when I retired from broadcasting. Basically the headend sets up a video session for the program if someone in the area tunes to the channel. This is like vod streaming except more than one viewer can utilize the session/stream.

It's a business decision, the network usually demands a per-subscriber fee for carriage on a cable plant.
kw71··on Fixed price of Coca-Cola from 1886 to 1959
Back in the 70s I heard from more than one adult that you'd get your five cents back when returning the bottle.

In the non-"bottle bill" area of the US where I lived, the last time I remember bringing bottles back to the grocery was during the 1980's.

That's why there's a warning light for this

> Not having to talk to an octogenarian about politics.

Nobody "has" to do this on phone. Of course there are people predisposed to this but you don't have to talk to them or you can change the subject. For instance I still enjoy discussing radio stations and usually it's interesting to hear about someone's elaborate construction and what they are doing with it while they are willing to hear how I am getting over the equator and atlantic with no amplifier and a shitty piece of wire.

kw71··on C64 OS: A Commodore 64 OS with Modern Concepts
It might add to the understanding, for those who are familiar with some other legacy stuff, to note that the cbm serial data port was a reimplementation of ieee488/gpib in a shift register style to cut down on the cabling cost. It was synchronus but some fastloader software reimplemented it in an async fashion (thanks to being able to upload code to the drive) along with changing the clk wire to be another data wire.

I think the digitizing oscilloscope is quite an advantage compared to the old stuff ;)

I am a die hard LeCroy user and fan, but recommend the rigol when asked what to buy. For most people, my criticisms of it are of no concern (I am frequently chaining instruments with GPIB and operating them remotely, and the usb stuff on the rigol doesn't fit into that and just too slow.)
kw71··on Ask HN: Favorite teachers on YouTube?
Oh god, not eevblog. That unlistenable whiny voice and his production values. I tried to tolerate it once but all he did was break stuff. And there's so much he got wrong that it's difficult to believe that he ever had a job.
kw71··on Ask HN: Favorite teachers on YouTube?
I wish he would grow up, cut the profanity, sex talk and ethnic bashing so that my kid could watch.

Or maybe they can monitor the wires on the legitimate read head instead. This was possible on a formerly common fuel dispenser in the USA

kw71··on Ask HN: Ever had a “are we the baddies” moment?
It depends a lot on the crops and the actual production methods, but from talking to my neighbors at the post office, in organics, sometimes more land is consumed (since production per unit area can be lower) and soil erosion is higher (you cannot no-till without herbicides.) I am not very well versed in this but simply wanted to point out that our assumptions may not be correct.

As for traditional production, herbicides, pesticides, and genetic contamination are big issues.

kw71··on Ask HN: Ever had a “are we the baddies” moment?
Yes I have five Rhode Island Reds and four Dominiques. They are all hens. They reached adulthood this year, each bird lays an egg every 1-2 days.

So far we have only been doing the eggs but expect them to stop laying when they reach 3-4 years old. This is my first flock so I don't really know yet. I am not sure if I have the guts to prepare a bird for meat.

kw71··on Ask HN: Ever had a “are we the baddies” moment?
I live in an agricultural area, have worked on industrial farms and hatcheries installing and maintaining computers and machinery, and keep livestock in my backyard.

The videos you see are extremely one-sided and manipulative. You cannot do anything right by these people. I am personally against, for instance, debeaking, and the production of foie gras is horrible on a Holocaust level. But for example I saw one recently that criticized the use of nipple drinkers that guarantee clean water for the birds instead of letting them drink water from the ground that's contaminated by feces. Another campaign I was exposed to this year misrepresented a cattle crush as a device that actually crushes cows, instead of its actual purpose to immobilize an animal while it receives medical treatment. There are a lot of good points to be made about cruelty in industrialized farming, but they ruin it with these shock videos and ridiculous assertions.

These tactics and misrepresentative propaganda, while they may be effective at fundraising from young and gullible city people, have caused states to pass laws making it a crime to film undercover at farms, and I believe that this is a setback for the animal rights movement, on top of some of the proponents' general dishonesty.

Vegetable farming is not a great thing for the environment either, and sometimes "organic" production does more harm.

Battery cages bother me and eggs produced differently are ridiculously priced (a dozen normal eggs costs $1.10 at my walmart today, recently the price has been below $0.30.) So I started my own flock. Today I have nine happy birds and am not supporting the battery cage operation, which incidentally was the subject of a salmonella-related recall this year. I hope to be bringing home some turkeys from the farm fest in the next county in a couple weeks.

I have a local homeless shelter that takes clothing. I know they are not connected with any industrial profit machine.

They figured this out at McDonalds in Moscow. Kudos to CFA, queue management at QSR are otherwise seriously lacking.

The case might be made that these people were sentenced to prison, not slavery or involuntary servitude.

Why don't you set a breakpoint just before it encrypts what it's collected, peek in memory and find out for yourself?
