A guy bought a bootleg Sunton 4.3" inch off AliExpress. For those of you not familiar with it, it's basically a clearinghouse for chinese knockoffs and a good source of hard to find electronics, even if it's sketchy as hell.
Anyway, he couldn't get the display working, because the thing doesn't advertise what it knocked off, did not come with schematics, nor code.
Based on little more than an image and the name of the LCD controller it used I was able to find the sunton device it was clearly a copy of.
Then we got the display working with the Sunton code.
Now it uses a different touch controller IC than the real mccoy so I'm having the guy run an I2C scan to find out the address the device reports on.
From there I will basically work my way backward to a touch driver chip.
It feels a bit like old school hacking.

so, a number of my clients allow me to submit IT support requests via email. Since I'm not an employee, I have no access to the employee portal. I'm left to emailing support-asses@yourguess.com. I made that last part up.
me: "Hi, your remote server is not accessible, and I am on a tight deadline. Help."
email: "Opened on your behalf..."
email: "Your incident has been re-assigned..."
Via email, I have no ability to tweak the priority level. Or get any contact. I need to start an IT support company

When looking for IT support software that was on premises and not online, I was amazed how difficult it was to find something that catered for both our support and IT department needs. It seems support and development are different worlds and they have no clue what's happening on the development side or how information should be coupled with e.g. Git or Continous Integration systems.

I had some fun with a bit of Microsoft nonsense the other day. I have a rather large hosts file - it's over 600KB. I read something about various devices phoning home to them with every URL visited so I put that address into my hosts file and mapped it to 127.0.0.1. I think it was urs.microsoft.com. Adding that single line to the file triggered the AV program at work and it was deemed to be malicious. At home it triggered a medium level warning when I did a virus scan. I removed that line and it accepted the file with no warnings or notification of any kind.
Apparently Microsoft deems it to be an act of malice to block one of their sites and I think that is nonsense.

Thirtysome years ago I designed and built cryptographic modules for EFT processing. Early days...
In those days there were two main algorithms for PIN verification.
The IBM Derived PIN system used data from the mag stripe (some of the account number and other fields) to crunch up with DES and other things to generate the expected PIN, which was verified by direct comparison (at a processing system, since the terminal did not have the relevant DES keys etc).
The (more popular) VISA method took the PIN and some stripe data, crunched them up and came out with a 4 digit value which was compared with the PVV (PIN verification value) from the stripe (or issuer's database).
This can be viewed as an elaborate hash function (4 digit PIN -> 4 digit PVV)
I investigated its properties as a hash, and (re-)discovered some interesting statistics.
Obviously a 1:1 mapping could be fairly easily brute-forced, so information is "destroyed" to make it a one-way operation.
As a consequence, looking at the PVV space:
1/e (almost 37%) of PVVs are unreachable - no corresponding PINs
1/e have one PIN mapped to them
1/2e (over 18%) of PVVs have TWO PINs that map to them
1/6e (6%+) of PVVS have THREE PINs that map
1/24e (1.5%+) have FOUR ... and so on
So, (back in PIN space) there is a very real chance that your card has more than one PIN that would work. (Good luck finding the other(s)!)
That fact blew the mind of more than a few bean-counters and auditors....
With regard to OG's thread below, we had requests from card issuing institutions to NOT generate "simple" PINs.
In the end I think we discarded PINs with 4 consecutive digits or more than two repeats.
(A little repetition is good - my favoured PINs have two characteristics:
They can be keyed by laying my hand over the PIN pad and merely flexing fingers.
They include a repeat so even keen watchers wind up missing something.)
Some time later, customer selected PINs (and PIN change terminals) hit the streets...
Ah, nostalgia (ain't what it used to be)!

American here for context
In the light of recent revelations of MS cooperating with the CCP and the PLA and the fact that the DoD and the Feds (I know that's redundant) moved all their crap to the cloud - all of it classified - none of it protected by the OS, I give you this...
So, I have deliberately covered my built in webcam. I login through a password or a pin. The login process or whatever it is has thrown an exception condition. I cannot login. The mouse has gone stupid. The laptop is hung.
The inmates are in charge of the asylum.

Well, just uncover your webcam, submit a new blood sample, and schedule your subcutaneous tracking capsule injection. You will be right as rain in no time!

the part that I found hilarious was the exception condition.
I read all of the time the holy grail for developers is to get a job in the big 5. F*** if I know the term now, it comes up now and again. I'm just one of those grunt developers that face palms when they do not handle an obvious situation - and honestly I'm not sure covering the webcam caused it. But don't you think that the login screen should be crash proof?

I was going to make the Subject
"It is your computer BUT we will tell you how you can use it"
This is a Hardware Question if it should not be in the Lounge
Please inform me where to post
Config
W7 64 bit Pro
Firefox browser DuckGo search engine
Chrome Block all Cookies
I have a VB app that stores data in SQLite DB the name of the YouTube site and a link to open the site with a list of all the videos.
A number of things are failing
1 The site will not load content if I use "Open Link in New Window"
2 The site will not load content if I use "Open Link in New Tab"
This varies no consistent behavior political ads show Liberty Mutual ad blocked ? ?
3 In Firefox I turned OFF "Block Popup Windows" it was on OFF no change
As of now the ads do not show but I am presented with a skip button to close the ad
that did not show
If I login to Google then Google and Firefox seem to play nice
except "Open Link in New Window"
Any suggestions on how to make Google and Firefox play nice?
Any settings I should change in either ?
I did try just using "Block 3rd Party Cookies" ONLY no change

I know that Google Chrome now blocks all 3rd party cookies. As for the other browsers, they may also block 3rd party cookies, but I honestly don't know. It's something I'd have to check.
When it comes to blocking all cookies, I think it would inevitably interfere with the function of most web pages. Instead of blocking all cookies, require the browser to prompt you whenever a page sets a cookie. This way, you can allow cookies for the websites you trust, and disallow all other sites by default.
Take a look at Google's/YouTube's cross-origin-resource-sharing policy. That could shed some light on things. Google may require you to set some sort of HTTP request header in certain cases.
If the problem that you are experiencing occurs in the same way across all browsers, I get the feeling that it would be a CORS issue.
You may also want to try disabling all browser extensions to see if that has any effect. I recently encountered a bug on my site. It turns out that a specific plugin was causing the error. I disabled the plugin, and the problem is fixed.

3.4M PIN numbers that were pulled together from a whole bunch of data breaches have been heat mapped, and they are quite interesting (to me at least): https://www.grc.com/miscfiles/pin.png[^]
Given that most (if not all ATM / shop card readers work with 4 digit PINs, it's interesting to see what people generally use. Notice the lines and clusters: identical pairs (0000, 0101, ...) birthdate day and month, birth year seem to be pretty common, but it's interesting to note two things:
1) There are a small number of "empty" or "near empty" cells where people just aren't disposed to use that combination.
2) 20 out of the possible 10,000 different PIN values are used by 27% of the population ... so if you want to "brute force" a PIN, those are the ones to try first - if you are using one of them, it's probably time to change it:
1234, 4321, 0000, 7777, 2000, 2222, 9999, 5555, 1122, 8888, 2001, 1111, 1212, 1004, 4444, 6969, 3333, 6666, 1313, 1010

Very interesting picture. Any four consecutive digits appear to be highly used.

Yeah - it's surprising how much human beings can skew what you might assume was pretty random data!

We're all a bunch of skew be do's.
These numbers are interesting (7410, 7942, 8520) since they don't seem to follow any pattern.
|
|
|
|
|
No pattern? 7410 goes down one side of a standard keypad, while 8520 goes down the middle.

Totally missed that. Thanks!
