I found a bug in my UIX library having to do with DMA and multiple transfer buffers. It only reproduces on one platform. I've narrowed it to a specific process, but I still don't know why it halts. It doesn't do it right away, so it's an intermittent problem. The best kind.
*cracks knuckles*
Prior to working on lil embedded widgets I was spoiled. I had numerous ways to do forensics on my running code, not the least of which was a debugger.
I don't typically have a debugger anymore, and while it's possible to use debug probes with embedded gear they're usually so slow that I want to get out and push.
Now since I don't have one, I've been forced to think more clearly about how my code runs and what it's doing at runtime at any given point.
One day a guy told me GFX was failing after a couple of days when writing text. I immediately narrowed it mentally to three places within a labyrinth of code, with a most likely culprit that turned out to be the thing. I knew it because it smelled like heap frag and I was right.
That's just one example. The opener of this post is another, assuming I'm right about it (I am)
A few years ago I wouldn't have been able to do that.
I'm super glad for these new abilities. It feels a bit like a superpower.

I installed VB6 and got some old stuff running![^]
That's about three days in lost productivity, so I hope it will be worth it 
Registering the COM Callable Wrapper was a pain and took most of the time.
I needed to run regasm.
The trick was in setting the /codebase parameter, which shows an error, but still does something that made it work 
Also running it with the -tlb switch somehow works miracles.
For anyone who may have to do this sometime:
regasm -tlb C:\Windows\SysWOW64\MyCCW.dll
regasm C:\Windows\SysWOW64\MyDLL.dll /codebase /tlb:C:\Windows\SysWOW64\MyCCW.tlb The VB6 codebase has a total size of 1.63GB, plus VB6, which is another 3.77 GB, makes it 5.4 GB.
The VM I needed to run it was a staggering 203 GB, which takes quite a chunck out of my 1 TB drive
It now sits safe in some external storage (I don't dare delete it yet) 
That alone should be worth it

Did you know that MS Edge has a built-in VPN?
It automatically applies VPN when you are connected to a public wifi.
Here are some more details[^] which I'm reading now.
I work out of a coffee shop once a week so this is important to me.
I'm trying to figure out :
1. how to know I'm actually protected
2. how "much" i'm protected by this VPN.
It is very interesting that MS is doing this though becuase it seems like the obvious thing to do that no other browser seems to do. Others you have to pay for separate VPN.

Yeah, because it's still 2010, and every site on the net is still using HTTP rather than HTTPS, right?! 
Whilst there are still reasons for using a VPN[^], the MS page you linked to seems like it was written by a gibbering idiot marketing executive who doesn't understand the first thing they're talking about.

I've wondered about that. So if I'm on an HTTPS site, then the moment I hit SUBMIT the data is encrypted locally (using the public key of the target site) and then transfered so even a person on same wifi can't see it right?
The one thing I'm looking to be protected from which I know is a current issue is token grabbing.
Here's what I mean. You are already signed into your Google account on your laptop. When you go to a site like stackoverflow or CP that you use your google credentials and you're on the public wifi then the nefarious actor can grab your token and use it to sign into your account.
I'm hoping / guessing that the VPN would protect me from that. But I'm wondering how I could prove that it does that??

Correct.
If they had enough control of the network, they could see your DNS request(s) and know what site(s) you were connecting to, unless you use DNS over HTTPS[^].
They could see the IP address of the server you were connecting to. They could potentially the SNI[^] header indicating which site, unless the server uses ESNI[^].
But they would not be able to see or modify any of the request or response data, including the URLs, query strings, headers, and request bodies.
(Unless of course they had installed malware on your machine, or installed a malicious root certificate allowing them to MitM any site. But if they've done that, you've got bigger problems, and a VPN won't help you.)

Again, assuming all the sites involved are using HTTPS, then nobody else can see the cookie / token to grab it. It would be part of the data that was encrypted.
And I doubt Google would allow any site not served over HTTPS to use their OAuth service to sign users in.
raddevus wrote: I'm hoping / guessing that the VPN would protect me from that.
If you're accessing sites which are not using HTTPS, then a VPN would prevent users on the local network from seeing or messing with your traffic. But it would not protect you if someone was inside the VPN provider's network and monitoring the traffic! All you've done is moved the point of trust from the people running your local network to the people providing the VPN.
There is also the potential of attacks against the VPN itself - for example:

Fantastic information (and links). I really appreciate you taking your time to explain these things to me.

The solution to the token interception is to not use Google or Facebook for federated logins. Why would you want to let these two advertising companies know where else you go on the internet?

Yes, you are correct, but even though I'm a "technologist" I am also a lazy human.
And I have 257 passwords in my password manager. This would mean even more.
I know that's not a great reason but I like the federated thing for sites I trust like this one (CP).

I opened Edge and then Copilot and ask this question: tell me about Edge's new vpn service
Here is the response:
Certainly! Microsoft Edge now offers a built-in VPN service called Edge Secure Network. Hereβs how it works:
Encryption: Edge Secure Network encrypts your internet connection, making it secure and private.
Location Obscuring: It hides your location and IP address, preventing third parties and hackers from accessing your sensitive data.
Automatic Activation: The VPN activates automatically when you connect to open Wi-Fi networks or visit unsecured websites.
Limitations: Currently, it provides 5 GB of data and is not available for enterprise users.
To enable it:
Open Microsoft Edge.
Go to Settings > Privacy, search, and services.
Turn on Microsoft Edge Secure Network and choose Optimized3. Enjoy safer browsing with Edge Secure Network! 😊
It does say not for enterprise users and I couldn't find it in my settings, but I am an enterprise user. I'll try at home later and see if I can find it.
HTH
Jack of all trades, master of none, though often times better than master of one.

Great. All these free VPN services make it easier for the most toxic people on the Internet to evade bans at places with comment sections, including one I moderate.

Web2.0 is dead. Comments are dead. Turn off the comments. No one comments any more.
This is me, not commenting. 
Long live Web3.0 You should only allow people to create NFTs which contain their comments, for upload to your site.

I have some article ideas (web stuff) and I've learned enough about React to be dangerously dumb about writing React code, and learning that I sort of hate React.
But React seems to be all the rage, and given one of my article ideas is implementing a sidebar menu (which I know has been done but all the example I've found are crappy) but I don't want to create another crappy article on sidebars, I want to show how to do it right, and I'm doubting whether I know enough to accomplish that.
I don't know if I know enough. And I've been using the older "class" way of creating React front-end stuff, not the newfangled "hooks" way, which honestly defies for the most part my understanding, no matter how many YouTube videos I watch. So it seems I would first have to understand hooks to appease the modern React coder. 
And then, I'm pretty much loathing how React does things with state management.
And then I watch videos on what is coming down the pike with React (among other things, some major handwaving about async stuff that only a React geek would comprehend, maybe) and I get the sense that React, and its evolution over time, has been and continues to be quilt patches applied on top of fraying quilt patches, which leaves me wondering, how solid is their core architecture to begin with?
So I'm stuck - I want to write some web articles but I'm not convinced that React is where I want to continue my learning, and all of this has made me gunshy of other frameworks. No wonder I roll my own, but that's besides the point.
Suggestions?

I feel that same way about React specifically.
I wrote an article here that I would really appreciate you taking a look at: LibreGrid: Drop Into Your App, In 5 Minutes CRUD Your Custom JSON Data[^]
I built this thing that is custom and allows you to retrieve, display and edit data from any webapi but then I just froze on it.
The things I like about React:
1. You can add React into any current web app easily -- just replace a section with a component.
The things I don't like about React:
1. it changes a lot - one thing is I like JS classes to wrap stuff and now they have moved toward function-based stuff (I know JS functions are like classes but still different).
2. State stuff and all those add-ons Redux etc. I want basic stuff not all that other stuff
3. It is confusing to me how to create a stand-alone component even though supposedly that is what React is supposed to let you do -- I mean a component I can just "drop-in" on a web site.
I hope you'll check out my article and let me know what you think.

I'll definitely take a look, and I definitely have concerns about the how often it changes and the state stuff.
And weird stuff, like I've been researching how to create components dynamically (like, lets say I have metadata that says I need a datetime control, a dropdown, whatever) and stumbled across this bizarre statement that a tag in the render, if it starts with a capital letter, is what makes React "know" that it's a component, not say, I guess, an HTML element. And then there's something about the component referencing the actual component you want, and magic rendering happens.
That capital first letter thing just seems so kludgy.

I have worked with React and have something of a love-hate relationship with it. While it has some interesting ideas, and I do like the functional-first approach to the design of React, my big problem with it is the "throwing the baby out with the bathwater" approach they take to new releases. With React, there is always a latest-and-greatest way of doing things which is the marketing equivalent of "new and improved" features which are incompatible with what was there before. Granted, this is all opt-in, but it does leave you with the impression that you're doing things the wrong way, even when this was the right way 6 months ago.
