    Would be nice. Not sure why LTT hasn't been doing this. I've never seen it for any of their streams. I saw one for GN's stream after this one.

    BlueJedi reacted to TheLastMillennial in Texas Instruments Bans all ASM Programs/ Games on TI-84 Plus CE Calculators.   
    EDIT: A jailbreak has been released for OS 5.6.0 and below!
    You can find the topic about it here:
     
    Original post:
    I know I'm new to this forum, but I have been an active member of the calculator community for over 4 years. I'm trying to spread the word about this as much as I can, hopefully achieving a segment on TechLinked, and to give TI enough negative backlash to consider negotiating better terms with the community. I'll keep this article as an overview, but I'll link my in-depth sources at the end.
    If you want to get up to speed quickly, I made a video that summarizes the vast majority of all the information I've gathered across dozens of sources! There's a lot of information that wasn't covered in this thread so check it out if you want to know everything!

    What exactly happened?
    Just a few days ago, TI Education announced that the most recent OS for theTI-84 Plus CE (-T) and TI-83 Premium CE removes the ability for the calculator to run any Assembly (ASM) code. With the decision planned to go global, this means that any program written in ASM or C will not run on any CE operating on the newest TI OS 5.5.1 or higher!

    Why did this happen?
    One big factor in the decision to ban ASM was due to a video created by a student and a teacher that showed the exact steps to bypass a Test Mode restriction in OS 5.2.2, an obsolete, 3 year old OS. What made the matter worse is they passed the issue off as if it were still present in modern OSes! With the video gaining almost a quarter of a million views, TI thought they'd need to take some drastic measures to uphold their Exam Mode security reputation.
     
    Why is this so frustrating?
    This is quite a punch in the gut for the community, TI had given TI-Planet (a very reputable TI forum that has been reporting on calculator news for over a decade) a beta build of OS 5.5.0 to review and post about. This build given to TI-Planet had all the benifits of the new Python abilities, however ASM was not banned on this build. To the community, it looks like TI knew we would hate the removal of ASM and therefor gave a different build to us just to drum up support. Then when release date came, they pulled the rug from under our feet and released OS 5.5.1 instead which did include the ASM restrictions
     
    TI-Planet, has privately shared security flaws related to Exam Mode TI needed to fix, and kept vulnerabilities a secret as to not cause this exact situation. TI Planet has put so much meticulous care into protecting the hobby of thousands of students and future Computer Science Majors, like me, it's infuriating to see one clumsy video with a quarter of a million views set years of hard work go up in smoke.
     
    TI Planet's time trying to protect the community isn't the only thing wasted, the hundreds developer's countless hours spent creating amazing content from overclocking utilities, to math additions like CAS, and games will become obsolete when newer calculators inevitably outnumber older ones. TI does offer alternative programming options like TI-BASIC and Python, but as TI Planet user jean-baptiste boric points out on Cemetech:
    Source: Cemetech: English
     
    It's also infuriating that TI's consistent reactions of killing a fly with a sledge hammer has done nothing to solve their security, in fact it has only worsened it. I think forum Planet Casio explains it better than I can:
    Note: I have paraphrased the French to English translation in order to make it sound as coherent as possible.
    (Source: Planète Casio: Français | English)
     
    Now that ASM is banned and this situation can't get much worse, the community is already finding exploits that allows not only the ability to run ASM code anyways, but ways to bypass TI's insecure Exam Mode (which was only ever 'secure' because the community was careful not to release the exploits to the public). The community is already brainstorming alternatives that will both satisfy TI and the dedicated programming community. We're doing our best to come to terms with TI and avoid creating another cat-and-mouse game of finding and patching exploits (which happened on the Nspire).
     
    Conclusion:
    Like I said at the beginning, my goal is to spread the word about this as much as I can. Although this is only effecting the CE line up of calculators right now, TI has not ruled out releasing updates to older models that also bans ASM.

    While we wait for our results heres one...
    Just be careful because people are going crazy from being in lock down! Actually I've just been talking about this with the microwave, toaster while drinking coffee and all of us agreed that things are getting bad. I didn't mention anything to the washing machine as she puts a different spin on everything. Certainly not to the fridge as he is acting cold and distant. In the end the iron calmed me down as she said everything will be fine, no situation is too pressing. The hoover was very unsympathetic... told me to just suck it up, but the fan was more optimistic and hoped it would all soon blow over! The toilet looked a bit flushed when I asked its opinion and didn’t say anything but the door knob told me to get a grip.The front door said I was unhinged and so the curtains told me to ........yes, you guessed it 😝.....pull myself together. Then I just asked the computer she said to just restart your self and everything will be running smoothly 🤣🙃

    That's fair. Not suggesting a permanent solution for all your systems. If the issue is because you're seeing power dips, than a line conditioner will only get you so far. A good line interactive UPS is a line conditioner too and makes up for any shortfalls from the wall. They usually give somewhat helpful real-time power stats too. Can be helpful to see what the wall power is doing while you're overclocking.

    BlueJedi reacted to Gorgon in RX5700XT on Linux - Works!   
    Well the Kernel 5.5 attempt was a dismal failure. It appears the preview drivers are built against 5.3 and dont work under 5.5 (DKMS errors). Which kind of sucks and I couldn't be bothered at this point to try to uninstall the preview drives, upgrade the kernel then try a re-install of the preview drivers.
     
    So I've spent part of the day getting the GPUs instrumented under Zabbix so I can start seeing the long-term trends.
     
    So far I'm seeing averages of 999,431 and 1,003,163PPD

    Following instructions from a kind user on FoldingForm I managed to get my 2 new RX5700XTs working on Ubuntu 18.04.4.
     
    First you need to be running the 18.04.4 with the Hardware Enablement (HWE) so you have the 5.3 Kernal.
    Next you need the Adreneline 20.10 Preview Drivers
    Unpack them:
    sudo tar -Jxvf amdgpu-pro-20.10-1028677-ubuntu-18.04.tar.xz change to the directory:
    cd amdgpu-pro-20.10-1028677-ubuntu-18.04 install the drivers:
    ./amdgpu-pro-install --headless --opencl=pal Then add the unprivileged fahclient user to the video group:
    sudo usermod -a -G video fahclient Replace the systemd service file so that fahclient loads properly:
    sudo nano /etc/systemd/system/FAHClient.service [Unit] Description=Folding@Home Client After=network.target [Service] Type=simple ExecStart=/usr/bin/FAHClient /etc/fahclient/config.xml --pid-file=/var/run/fahclient/fahclient.pid --daemon PIDFile=/var/run/fahclient/fahclient.pid User=fahclient RuntimeDirectory=fahclient WorkingDirectory=~ [Install] WantedBy=multi-user.target Reboot:
    sudo shutdown -r now  
    If you get No GPUs found errors then add the GPUs.txt file
    sudo wget http://fah-web.stanford.edu/file-releases/public/GPUs.txt -P /var/lib/fahclient/ If you get OpenCL index errors you should install the Dev package:
    sudo apt install ocl-icd-opencl-dev and you might need to remove then re-install the FAHClient packages or just set the GPU and OpenCL indexes manually to 0 and 0 for the first card and 1 and 1 for the second etc.

    BlueJedi reacted to Gorgon in HOWTO: Remotely Access your Folding Systems - Part 1 FAHControl   
    There's been a few posts lately where people have been having issues accessing a Folding Rig from another Computer using the Advanced Control client.
     
    Couple of important points. Even on your local machine Folding is divided between two parts. The Server which manages folding the Work Units (WUs) downloaded from the Work Servers and the Client that allows you to Configure, Monitor and Control the Server.
     
    Just to be confusing the server is called FAHClient and the Client can be either the Advanced Control Python Application or the Web Server built in to FAHClient. These two control processes on FAHClient have their access restricted by default to just the computer they are running on (the "localhost" or 127.0.0.1 (loopback IP Address)). The WebControl runs on TCP Port 7396 and can be accessed by any browser on the computer the Server is running on by the URL:
    http://127.0.0.1:7396 where 127.0.0.1 is the IP Address referring to the localhost or the IP address of the computer can be used:
              
    http://<ip address>:7396 The Advanced Control uses TCP port 36330 ( and can be also accessed using using any TELNET client that supports UNIX terminal emulation such as PuTTY, which the Windows Telnet Client, unfortunately does not )
    In order to permit access to either the Web Control or using the Advanced client on another PC you have to allow access on the remote system.
    Assuming you are on a Local Area Network (LAN) and protected by a router with a firewall blocking external connections the easiest way of doing this is to use the Advanced Control application on the system you want to manage remotely to add the IP Network Address and Mask that will allow all the hosts on your LAN Access without a password.
    Using a command prompt and running the command:
    ipconfig you can display your IPv4 address and then click on the "Configuration" button in Advanced Control enter at the bottom of the "Remote Access" tab your network address and mask in BOTH the "IP Address Restriction" and "Passwordless IP Address Restriction" Dialogs. You LAN's IP Network will typically be 192.168.1.0/24 as this is the default for most home routers.
    Note that you MUST leave in the localhost address 127.0.01 and use spaces to separate the values.
    Once you have entered the new values and saved them you have to close the Advanced Control Application and Stop and Restart the FAHClient server. If you are in the middle of folding a WU first pause the Work Unit before closing the Advanced Control. To stop the server right-click on the "Folding" applet in the Taskbar and select quit. To restart the server click on the "Folding@home" desktop shortcut which will also launch the Web Control.
    Un Pause the Work Unit to Resume Folding and then try to access the Sever from another computer using either a web browser or the Advanced Control if it installed.
