#softwaredevelopment is broken. Everywhere. Academia, big tech, business. I did a detailed study of X when it was Twitter and showed how they hid errors and faked results. See blackliszt.com/twitter/. Sadly, there are proven methods to produce great software, which bureaucracies

#SoftwareDevelopment is a nightmare. Takes too long, bug-riddled, doesn't meet goals. There are proven methods that do work that are mostly ignored by big tech, academia and the rest of the establishment. Here is a path for getting good results fast. blackliszt.com/2024/06/the-am…

The murder of the United Healthcare CEO is inexcusable. When reading about it, I learned about how his company was subject to the largest #securitybreach and #ransomware computer outage ever. Months of chaos and over 100M people with private information for sale on the dark

Yes there is too much #regulation. Cutting them is good. But the underlying problem and the cause of their growth is that they tell you HOW to get things done when they should tell you WHAT to get done. Most regulations are like telling people is great detail HOW to get to work

Senator Wyden is demanding that #HHS impose #MFA on Health Care companies to prevent data leaks. MFA will make security worse, not better. Here's why and how to really fix the problem: blackliszt.com/2024/12/mfa-wo…

@SenatorWyden and many experts proclaim that a lack of MFA enabled the hack that led to the huge security breach at United Healthcare. Imposing MFA will NOT fix the problem. There are solutions, but all the experts ignore them, even thought they're proven in practice, for example

AI could automate what doctors do. The technology exists and has been proven. It would reduce costs and improve health. But it's unlikely to happen soon. blackliszt.com/2025/01/ai-can…

A quick summary of how to reduce medical costs and improve health. Big subject, big ideas. blackliszt.com/2025/01/how-to…

Wellness visits and disease prevention sound like terrific ideas. They are widely practiced. In fact, they are a major driver of the explosion of healthcare costs in recent decades -- even as health and longevity have been declining. Something's going on here. Understanding the

A form of AI can automate medical diagnosis. I talk about the obstacles and the path to success. Most important, I'm concerned that automation will further cement harmful medical practices that are currently standard. Automation should not happen until this is resolved. See

Voter ID and paper ballots are a great start. But they're not nearly enough to prevent cheating! How about we join most other civilized countries -- even France :-) -- and toss the machines and go to hand-counting the ballots. #VotingPlatform #voterID #paperballots

Voter ID and paper ballots aren't nearly enough to stop election fraud. Here's how to stop the rest of it, by concentrating on the "back office" where the counting takes place. blackliszt.com/2025/03/voter-… Governor Glenn Youngkin Elon Musk Donald J. Trump Greg Abbott

Generative AI is the thing. It's amazing! People are even turning to AI tools like Chatgpt for medical advice -- even a growing number of doctors! Can you get valuable health advice from a generative AI tool like ChatGpt? I ran some experiments, I got answers. They're not

I ran an experiment with Chatgpt and the Covid vaccine. The results were amazing. Amazingly bad. blackliszt.com/2025/07/chatgp…

Super-top software programmers are frequently criticized by colleagues and managers for not being team players, etc. There's another side to the story. blackliszt.com/2025/07/whats-…

The fraud that is broad and deep in Minnesota demonstrates that new regulations won’t assure election integrity. You can require paper ballots, voter ID, hand counting, whatever. If the local people who do the work ignore the rules, the results will be whatever the crooks want

These are the words of the first 16 scientists of 46 that have left the Intergovernmental Panel on Climate Change (IPCC) due to the corruption of science within the organisation. Dr Robert Balling: The IPCC notes that “No significant acceleration in the rate of sea level rise
