I have read this post however I still have a question. I understand that saying 32 bit processor implies registers of size 32 bit long each of which can hold up to 2^32 data. My question goes little bit further. So during the execution cycle, how does 32bit register span into the main memory? In order word, does it mean that each register can deal with 2^32 memory addresses so that any instruction in this region can be fetched in one clock cycle? Let's block ads! بخوانید...

On some Windows environments (Windows 7 and Windows Vista), I have some scripts running and one of the things those scripts are doing, is trying to copy files. The results of those commands are logged in a logfile. While looking into that logfile, I've just seen the following result: The system cannot find the path specified. This obviously is not very helpful (which file does he try to copy, to which directory, ...), so I would like to replace the existing copy commands by xcopy or other com...

I have a watermark.png that was made to overlay videos with 1280 width. When i use a different size video, the watermark is totally out of proportion. So i'm looking for a single command that can scale the watermark to fit the original video size. I do not want to resize the original video. This is the current working format i use which works fine with 1280 width videos. (watermark placed left-bottom) -i video.mp4 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=1:main_h-overlay_h-...

Why is my mac (Snow Leopard) asking me for installer changes (system.install.root.user) by itself? I do not recall doing anything to enable this. I feel like someone is trying to hack into my computer. I hope it is a false feeling. ...

In my php.ini, I see this option called Command buffer size, which is set to 4096. However, what is this and what exactly does this do? In what cases would you want to increase (or decrease) this limit? I tried googling around but came up empty. ...

I'm trying to create a Powershell script that watches a folder for new MP3 files and converts them to M4A format using FFMPEG and FDK AAC encoder. Since fdkaac.exe won't take MP3 files as input, I use this command, which pipes from ffmpeg: ffmpeg -i $path -f caf - | fdkaac -p5 -b64 - -o $outfolder$outname.m4a This works just fine if I enter it into a command prompt and the resulting M4A file that's generated has no problems. However if I run this from Powershell, the M4A file is created but co...

I am using Samsung SSD 850 EVO 500 GB. Instead of installing a fresh copy of Windows 10 on it, an old image of the OS created from an old HHD was used I am worried this may affect the performance/age of the SSD. Which I understood is made to run on 4k bytes per sector. screenshots are on my laptop now after the migration to the ssd. Let's block ads! بخوانید...

Yes, proof UPS,FEX ED, and etc all use them. QRcode are simple patte of binary values either a 1(black) or 0(white) and that is it. The squares can be bigger or smaller, but you still have a 2 digit alphabet. There are no different fonts,styles, or anything. Also because they are so uniform sizes can be auto-detected. They also built-in error checking which is never done,sure spell check can help on text but sometimes it also causes errors, with individual letters when typing or handwriting. If ...

Your dates show the 17th of each month, which I'm guessing is an irrelevant complication. Can we assume you're talking about whole months and not subdividing amounts by fractional months? –xa0fixer1234 12 mins ago I'm guessing you were busy re-entering things manually while I was embedding your original image. I rolled this back to the "pretty" version because I didn't notice any substantive changes. If you were actually changing things, we'll need to do some code formatting so your man...

I have a system that records video to disk, and sometimes the system has an error. I'm trying to recreate the recording system in the lab, without the actual camera (it's expensive and there aren't any spares), to attempt to replicate the usage patte that causes the error. I'm having trouble taming ffmpeg. Background: The video is captured in one thread continuously from an rtsp:// URL provided by the attached camera with this command: ffmpeg -i rtsp://192.168.0.10/h264 -c copy -map 0 -f segmen...

I'm having problems where email is showing up in an account that it is not being sent to. Email was sent from a PHP form with the intended recipient of [email protected] but the emails keep showing up at [email protected] Is there any way to tell if this is being caused by a filter or something at the ymail address that is automatically forwarding stuff to the earthlink address?

I need to time an object that stays still on a wall but may fail and fall off the wall after some time. Instead of sitting there for the fall that may never occur I would like to use a smartphone camera to sense motion as a trigger for a stopwatch. The app ideally would take snaps from the start of the timing and at the end so as to see what motion triggered the smartphone camera to stop timing... Any ideas? P.S. Did some research that comes up with one rudimentary app for timing laps of runners...

Is there a way to set up Microsoft Windows so you can enter accented characters (with diacritics, such as é, ř, ...) by holding a key and then selected the variant you like? I mean the similar way which works on tablets and mobile phones. E.g. you hold the key e and instead of auto-repeating the same character the system would offer you a small menu on the position of the cursor offering é, è, ê etc. Note: I am aware of other ways to enter accented characters. This question is purely about this ...

I have two LG monitors (different ones) connected to my PC, one via D-SUB and the other (a newer monitor) via HDMI. When my PC goes to sleep and sends the VESA sleep command, both of my monitors shut down and go to sleep. The D-SUB monitor's light tus yellow, but the HDMI one just completely shuts off. When I move the mouse and the screens come up from sleep, the D-SUB monitor tus on but the HDMI monitor stays off, and I have to tu it on by pressing the power button, after which it works fine. T...

I've been trying out tails on a USB flash drive. By default, when I create the persistence storage, it fills up the entire remaining space of the flash drive. This basically makes the flash drive useless for any "typical" usage, i.e. a simple, cross-OS storage device, because the encrypted storage is a pain to mount in many OS. What I was hoping to do is: install Tails on the flash drive in it's default FAT32 partition (the installer does this automatically) create a partition with the persisten...

I cannot alter my modem firmware and there's no legal way to enable bridge mode. I want to add a router so that I can have complete control over the network. If I use DMZ to achieve this, how secure am I? What would happen if an attacker is able to breach my less-secure modem (that is also a router) and change some settings like DNS? Is there any approaches to minimize risks? Router/Modem from my ISP¹ => DMZ => Router with DHCP and NAT => All my devices ¹wifi disabled, no wired devices ...

I have a todo script in my terminal where I add paths to folders that I am working on. For example badoop project X: /path/to/project/folder Then the next day I run badoop and I get the list that I have added. I would love to be able to click on the path and the terminal to cd into it! At the moment if I cmd+click it opens the folder in the finder. But is there a way to get the terminal to point to that path Let's block ads! بخوانید...

I am trying to dual boot windows and linux by putting my second ssd in this optical drive caddy. However, the caddy is not recognized by the BIOS. As far as I can tell from this site, I am running the latest version for my model (v1.21). When I tu on the computer, the blue light on the caddy lights up so I am assuming there is at least getting stata power if not data. Did I get a bricked caddy? Unfortunately I do not have another laptop to test it in. The ssd works perfectly if I put it directly...
