Key Safe Override
Kylee Evancho
Does anyone know how to disable kuka "safe robot override reduction active". I am trying to jog the robot at 100% speed but it jogs at really slow speed for some reason with message "safe robot override reduction active".
Check safety configuration. The message is set if safety config demands a slow velocity for whatever reason. Might be a violated monitoring range or some setup velocity bounds in safety configuration.
i would like it to check if file already exist, if it doesnt just copy file, else check if my function(s) is already in there, and if not, then add tmy functions, wrapped in a unique flag or something + add a flag that developer can remove if he/she is editing the function code.
while you will add override/class or override/controllers folder inside your module, Prestashop will automatically check override functions. If we are talking about chnage .tpl files inside theme while installation (or something similar), than you can add need checks in your code.
Looks like its already there, but why isnt people using it then when they build a module. Hmmm. Ive seen many modules that do the override in stupid ways with fatal consequences for other modules. So I guess I gotta learn how to use this. Thanks for enlighting me.
Do you know?
lets say Im building a module and Im creating a MyModuleController.php that I want to put in /controllers/front/
is there also a build-in method for that? I mean for the copy of file to /controllers/front/
I have created a simple module for testing override. When Installing the files are placing correctly but while uninstalling they are not getting deleted. More strange thing is the class overrides removes some lines from the override class file. Any suggestion experts.
It should not be necessary, Prestashop should remove the code from the override. You should not attempt to remove the file, because there may be other modules overriding the same class/controller, and you will break that other module if you remove it
In a particular class that extends ActiveRecord::Base, I need to update a different ActiveRecord object whenever this one is created. Is it safe to override the save method and do the following in the save?
In fact, given what you've said, it sounds like before_save is what you want, as you can catch any errors that occur whilst saving the second model and prevent the first one from being saved (by returning false from the before_save call).
Is it safe to override Free method? I'm asking because I would like to use something like this. I know it's very ugly to use TerminateThread, but in my case it's very critical to kill the process with all its threads immediately.
You can't override Free because it's not virtual. If you define your own Free method it will hide the TObject.Free method (note the compiler warning) if the static type is your class type. This is definitely not a good idea since the object will then never get destroyed.
However, sometimes we forget our codes or lose the necessary information to open the safe. In these situations, an override key can prove invaluable in regaining access to the safe without damaging its contents or the safe itself.
There are different types of override keys for various safes, including tubular keys, double-sided keys, and high-security keys. The type of override key required will depend on the specific make and model of the safe.
My bed goes to full extents when power off or klipper disconnect/restart. I use a probe for Z and need the Z_safe_home to z hop during G28. However, this is a problem (Z_SAFE_HOME) when the bed is at the full extent of travel.
Core XY system where nozzle is at the top of machine and Z moves up to the nozzle.

A user is trying to access a poorly maintained website using a modern OS (Windows 10) and web browser (Firefox 100.0). They want to download something from there, but they are seeing a security warning indicating that the host is using a deprecated TLS protocol version and/or has an issue with its certificate. The user been in touch with the person who owns the domain and downloadable content, and this person is being slow to get it fixed.
They are considering firing up an old Windows XP computer running an also-old Internet Explorer, which I'm open to letting them do, as long as they don't share their data on the network and take the device offline as soon as they are done. LMK if you can think of any reasons why this would be a bad idea.
The user can proceed to download the file - either by using http instead of https if the site allows it, or ignoring the browser's TLS / certificate warnings and proceeding anyway, or by using an older operating system from the same vintage as the site's TLS setup, or by using a command line tool such as curl or wget, or another method. But, as others have mentioned, a man in the middle (MITM) would be in a position to impersonate the site, and serve the user a malicious file instead of the true and correct file.
To mitigate this problem, the user would be well advised to verify the integrity of the file, by taking a checksum hash of the file after downloading it, and ensuring that it matches the known correct checksum for the file.
Even if the user isn't sending anything confidential to the site, they are downloading from it. Any attacker in the position to perform a MitM attack will be able to change any resource from the site and the clients cannot detect the attack.
What kinds of resources? For example, the attacker may replace every page with a message "This site needs Flash Plugin 14.5.6.7.8.9rev114 to run, click here to download." and most users will happily download the file.
Yes, you need TLS for read only websites. Because otherwise a rogue WiFi hotspot can serve whatever content it wants on your domain and the user has no way to know it's not authentic. Also, browsers disable features on non-secure websites and display increasingly scary warnings about the website being insecure. So just set up let's encrypt with automatic renewal.
If the file is "look how funny my dog jumps" video and the computer where the user downloads and uses it is not of a national security importance and uses a wired connection to a reputable ISP, then - maybe ok.
A poorly maintained website is probably poorly maintained in many aspects. It may as well be already controlled by malicious parties, because the owner lagged not only with TLS certificate renewal, but with the security updates as well. The site may be already serving malware.
The potential for man-in-the-middle attacks mean that any executable code downloaded from the site is suspect. Do not trust any binaries unless and until you can verify their safety independently.
There are two ways that I know of: by hashing the file and comparing it to a hash delivered over TLS or some other, secure channel, and by uploading it to a site like VirusTotal that scans it with a bunch of malware scanners. Neither approach is flawless; malware can still hide in there, but they greatly mitigate the risk. If you're in a high-stakes situation or have any additional reason to suspect the file, confining it to a sandbox (e.g., a virtual machine) is a good idea.
If you're just downloading file that you will treat as plain text, it's not really a risk, but do beware of media files that could exploit vulnerabilities in a player program. As fraxinus helpfully mentioned, the site itself can try to exploit browser vulnerabilities (JavaScript or otherwise). Of course, the file can also simply contain bogus data; if it's a financial report, don't trust the numbers.
All of these things can also occur even with TLS enabled if a site is compromised by a malicious actor, so TLS is not a guarantee of safety, anyway. This is why we put digital signatures on binaries... although build servers and dependency chains can be compromised as well. No security is perfect, but we reduce risks where we can.
TLS encrypts the traffic. Without that, as you've correctly identified, any passwords you send aren't secret. In addition to that, Internet Service Providers at the very least can trivially identify what is being transferred to you, including your ISP, the host's, and any others involved in the connection between you and the host. Other actors on your local network and on the host's network may even be able to see the traffic, depending on the network setup. If there is any reason you don't want the whole world knowing what specific page you are visiting and what specific files you are downloading, you must not connect without TLS. Even with encryption, law enforcement agencies can generally get logs from a host, but ISPs, criminals, and private investigators cannot so easily get ahold of them.
