wiseleo··on Waymo imported over 3,200 Zeekr robotaxis in the US despite 102.5% tariffs
They'll request refunds eventually. Consumers can't. B2B certainly can.
wiseleo··on Ask HN: What business would you build if you couldn't use the internet?
My fallback tends to be photography. There's always a need for someone who is better than a random person. I can be fully self-contained with my camera.
wiseleo··on License plate reader searches should require a warrant
When speaking, I use a short definition. When writing, I use the expanded definition so it's clear what it means.
wiseleo··on License plate reader searches should require a warrant
I always define them as "Remotely managed, field-upgradeable, multi-interconnected computing devices with full spectrum cameras and other sensory capabilities. Information is monitored in real-time by increasingly capable AI technology. They have edge AI capability for intelligent classification. They can be upgraded without announcement at any time. They can be replaced in the field with higher capabilities at any time. The data they captured can be accessed at any time by anyone with sufficient permissions granted by an entity capable of granting such permissions. Not all users have the same permissions. Multiple user interfaces with differing capabilities exist. There exists a capability to aggregate data streams from multiple sources provided the user has sufficient permissions. Deleted data remains accessible to users with higher clearance."

Here's a case study of what happens when this information is public (it's linked as the "data-driven" series). This information should not exist unless the plate is flagged and the reason for that is sufficient to obtain a warrant. https://www.eff.org/deeplinks/2026/04/open-records-laws-reve...

wiseleo··on I was interviewed by an AI bot for a job
I'd invite a fire marshal into that discussion. They'll know whom to call if it's not their purview, but electrical panels tend to be a fire risk.
wiseleo··on Show HN: Jemini – Gemini for the Epstein Files
Monumental and amazing work. Thank you!
wiseleo··on Ring cancels its partnership with Flock Safety after surveillance backlash
Nothing prevents them from having another meeting unless there's an act of Congress to do so.
wiseleo··on GPT-5 outperforms federal judges in legal reasoning experiment
Right... So how far are we from creating SIBYL? Watch that show (Psycho-Pass) to see what happens when AI starts judging humanity at scale and who is behind that "AI".

More to the point, this decade is going to set some scary precedents that would need to be overturned. Would AI know which case law carries more weight and which was purely politically motivated with no basis in reality?

wiseleo··on Gmail will no longer support checking emails from third-party accounts via POP
I've been using this feature (POP3 fetch from external accounts, send as external accounts) for over 10 years. It's unfortunate that it will break soon. :(
wiseleo··on We all dodged a bullet
I can't pass phishing training on my first try because it often has bad advice as answers they are convinced are correct. Reading headers is one of such gems.
wiseleo··on Job-seekers are dodging AI interviewers
AI interviews are just a survey with a slower data entry interface.

wiseleo··on Ask HN: Anyone using augmented reality, VR, glasses, helmets etc. in industry?
There is at least one use case where I would want AR. I was doing some cable runs last night 30' in the air, and AR would have been very beneficial to highlight the exact path instead of spending a lot of time confirming and reconfirming with the team.
wiseleo··on Show HN: Inspect and extract files from MSI installers directly in your browser
Thank you for InstallWatch Pro mention. That app tends to get reinvented every so often. I remember seeing something like it as early as 1996.
wiseleo··on The Microsoft Excel superstars throw down in Vegas
Oh it is a gateway drug. New Excel now features lambda functions. There is Python integration with Excel. VBA is tolerable once you understand real software engineering.
wiseleo··on The Microsoft Excel superstars throw down in Vegas
Game servers sometimes leak a lot of data to the client. I once built an app that would intercept API responses made by my legitimate game client and generate intelligence on every player's troop deployment on the entire server. It got to the point where I could track the logins of every player and predict whether they would login to attack during the next time period. Each player could deploy a fixed number of troops per each 24-hour cycle. There were 3 battles per cycle. Once they deployed all troops, they were just a spectator.

I recruited a 24/7 team and dominated that game. We could predict with 100% accuracy how the opponent's team members would deploy their troops, in what quantity, and when. :)

My data model updated a shared spreadsheet, so my team members could see the actions we still needed to take without having to learn a new UI.

wiseleo··on 16-Bit CPU in Excel
Great accomplishment!
wiseleo··on 400 license plate cameras coming to San Francisco
This changes surveillance from requiring the cooperation of a cell carrier to passive warrantless mass surveillance. This will be abused. https://www.eff.org/deeplinks/2015/01/what-we-learned-oaklan...
wiseleo··on Ask HN: Why aren't any of my classes taught by my instructors anymore?
I prefer pre-recorded classes. It saves me the hassle of taking notes and preserves the instructor's sanity. I don't like class discussions.

The instructor's role is ideally to answer questions. Having to orally re-deliver content to a huge room of people feels archaic and inefficient. This does require the students to be motivated to learn the class. The challenge is maintaining the motivation for the extraneous content required for a degree but perceived as unnecessary by many students. If I am learning information security, I am far less interested in art history.

I believe any course should be waivable by a conversation with the instructor. Someone using LibreOffice on Linux is wasting time in the intro to computers course.

I once took a course on introduction to Internet. I advised the instructor I was an experienced CLI Internet user but wanted to take his course to learn how to explain complex technical topics to a non-technical audience. I also informed him that asking me questions could derail class discussions. We talked about Unix shell applications like archie and gopher in that class.

The instructor was great and I learned a lot about presenting technical content to non-technical audience, which was my goal. He once asked me a question during a lecture on NNTP on the permanence of Usenet posts and I canceled his post with a control message. ;)

wiseleo··on Ask HN: How to find online employment for a person with limited functionality
Start growing your reputation on an online marketplace like upwork. Bid on small projects that don't take long. As your reputation grows, so will your earning ability.
wiseleo··on Ask HN: What 1980s/90s-era shareware did you purchase?
I don't remember my early shareware purchases, but I made some for utilities. I do remember receiving by mail a floppy for his freeware from someone who first sent me anonymous ftp instructions. I don't remember what utility software that floppy contained.

I recently paid for several license keys. My most recent license keys are for AirServer, which is an excellent Apple TV emulator for Windows and Netspot, which is a WiFi heatmapper.

Shareware is alive and well on the App Store.

wiseleo··on Ask HN: Technical and non-technical goals for 2024?
Complete SICP '86 and CS61A '12. That should help me build the foundation I am lacking.
wiseleo··on Remote controlling an HP 1670G logic analyzer with a Linux PC X server
The 16500-series logic analysis system mainframe has its little siblings as 1650-series and 1660-series. The 16700-series logic analysis system mainframe has its little siblings as 1670-series.

They support oscilloscope cards, except when they don't. Those are the 16530-16534a boards. Specifically, the earlier scope boards 16530-16532a have been reported to not show a trace over X for an unknown reason. I will investigate that in the near future. You will want the 16533a or 16534a oscilloscope boards. Alternatively, you can simply purchase the integrated oscilloscope versions of these analyzers.

You'll notice the 1670G model in the article has the 2ch scope built in. That scope works over X11.

This a deep rabbit hole, but my 16500B from 1992 came with a 102-channel logic analyzer and a 2ch 250MHz 1gsa oscilloscope. There are many other interesting boards it can support and I am acquiring them as opportunity presents itself. It cost me $150 including shipping. :)

Here's a good starting point into these machines. https://youtu.be/6w5w3ezpVHE?si=BfsiazkXvHK-L1MV

If you want your mind blown, consider that the 16500A came with a color touch screen in 1988 (I checked HP archives) and it could already be configured for X11 networking with the appropriate add-in card. There's also Windows software to operate these systems over a modem. The blank mainframe cost $7200.

wiseleo··on Ask HN: What's your "it's not stupid if it works" story?
Microsoft SQL Server Express has limits on its database size. Windows Internal Database, which is the same thing as far as APIs are concerned, does not. Well, it does, but the limit is over 500GB. So, I made Sharepoint and other vendor apps run on it.

In the same spirit, Microsoft shipped Business Contact Manager for Outlook on Office 2003 CD. That thing is functionally a CRM that was allegedly limited to 5 users. It, of course, runs on an SQL Server and so I made it run under Windows Internal Database, tested it with more than 5 users, and made it a lot more usable.

wiseleo··on Judge allows major 'right to repair' lawsuit against John Deere to move forward
As an electronics tech, I can reverse engineer just about any fault code being thrown at me by a computer. Logic analyzers and oscilloscopes don't lie and my equipment has more than 100 channels. There are countless EEs in USA. Some of them would rise to the challenge. I certainly would repair electronic faults in tractors. To me, they would be just another PCB.

There's no difference between having a capacitor replaced or EEPROM reflashed by someone wearing a green shirt and not. If the fault is gone, it's gone. Publishing the tools to validate repair would alleviate the pressure on JD's service network.

wiseleo··on Brother have gotten to where they are now by not innovating
I like Canon ImageCLASS series printers. They are not expensive, reliable, and some of them are software supported through Windows 9x.
wiseleo··on The new toll to drive into Manhattan won't change much by itself
Accessibility.

I was in NYC yesterday. I had a somewhat heavy carryon and had to deal with a few too many staircases. I could not determine where the elevators and escalators were easily. I am sure that information exists, but countless subway stations are inaccessible. Buses are far more accessible.
