HPR4348: Resizing the root partition on a PC

לפני יומיים

—

This show has been flagged as Explicit by the host. Background It all happened when I noticed that a disk space monitor sitting in the top right hand side on my Gnome desktop was red. On inspection I discovered that my root filesystem was 87% full. The root partition was only 37GB in size which meant there was less than 4GB of space left. When I thought back I remembered that my PC was running a bit slower than usual and that that the lack of space in the root partition could have been to blame. I had some tasks that I wanted to complete and thought I’d better do something about the lack of space before it became an even bigger problem. What happened As per usual all this happened when I was short of time and I was in a bit of a hurry. Lesson one don’t do this sort of thing when your in a bit of a hurry. Because I was in a hurry I didn’t spend time doing a complete backup. Lesson two do a backup. My plan was to get some space back by shrinking my home partition leaving some empty space to allow me to increase the size of my root partition. For speed and ease I decided to use Gparted as I have used this many times in the past. Wikipedia article about Gparted Official Gparted webpage It’s not a good idea to try and resize and or move a mounted filesystem so a bootable live version of Gparted would be a good idea. The reason for this is that if you run Gparted from your normal Linux OS and the OS decides to write something to the disk while Gparted is also trying to write or move things on the disk then as you could imagine very bad things could and probably would happen. I knew I had an old bootable live CDROM with Gparted on it as I had used this many times in the past though not for a few years. As I was short on time I thought this would be the quickest way to get the job done. I booted up the live CD and setup the various operations such as shrinking the home partitions, moving it to the right to leave space for the root partition then finally increasing the size of the almost full root partition. What I didn’t notice at the time is that there was a tiny explanation mark on at least one of the partitions. I probably missed this because I was in a hurry. Lesson three don’t rush things and be on the lookout for any error messages. When I clicked the green tick button to carry out the operations it briefly seemed to start and almost instantly stopped saying that there were errors and that the operation was unsuccessful and something about unsupported 64 bit filesystems. At this point I thought / hoped that nothing had actually happened. My guess was that the old live Gparted distribution I was using didn’t support Ext4 though I could be completely wrong on this. Lesson four don’t use old versions of Gparted particularly when performing operations on modern filesystems. Wikipedia article about the Ext4 filesystem I removed the Gparted bootable CD and rebooted my PC. At this point I got lots of errors scrolling up the screen I then got a message I’ve never see before from memory I think it said Journaling It then said something about pass 1 pass 2 pass 3 and continued all the way to 5. Then it talked about recovering data blocks. At this point I got very nervous. I had all sorts of fears going through my head. I imagined I may have lost all the contents of my hard-rive. The whole experience was very scary. I let it complete all operations and eventually my Ubuntu operating system came up and seemed okay. I rebooted the PC and this time it booted correctly with no error messages and everting was okay. I have often seen things said about Journaling filesystems and how good they are though until this point I had never seen any real examples of them repairing a filesystem. Both my root and home partitions were EXT 4 and thankfully EXT 4 supports Journaling which I believe on this occasion saved me from a great deal of pain. Lesson five it might be a good idea to use Journaling filesystems. Wikipdeai article about Journaling filesystems This still left me with the original problem in that I had little free space on my root filesystems. This time I decided to take my time and break the task up into smaller chunks and not to do it in one go. First I downloaded the newest Live distribution version of Gparted I performed the checksum test to make sure the download was successful with no errors. The next day I tried to write it to a CD-ROM something I haven’t done for a very long time. I initially couldn’t understand why I couldn’t click on the write button then I looked at my blank CD-ROM using the UBUNTU GNOME DISKS application. It reported that the disk was read only. I did a bit of goggling and came across a post saying that they had come across this and that they solved this by installing the CD-ROM writing application Brasero. Wikipedia article about Brasero ) Official website for Brasero Installing Brasero solved the problem and allowed me to write the image file to CD-ROM. I was actually surprised that it wasn’t installed as I’ve used this application in the past. Just goes to show how long it’s been since I’ve written anything to CD-ROM! I booted the CD-ROM to check that Gparted worked and didn’t see any explanation marks on any of my partitions. I was short on time and didn’t want to rush things so decided to stop at this point. Later on I popped the live bootable Gparted CD-ROM running version 1.6.0.3 AMD 64 version into my PC and booted it up. Everything seemed okay and there were no errors showing. I took my home partition SDA6 and shrunk it down by about 20 GB and then shifted it 20 GB to the right to the end of the disk. This left a 20 GB gap at the end of my root partition. I then increased the size of my root partition SDA5 by approximately 20 GB to fill the empty space. It took Gparted about one hour and 40 minutes to complete all the operations. The root partition is now reporting 61% full rather than 86% full. The root partition is now approximately 53 GB in size with 31 GB used. 22 GB is now free which is a bit more comfortable. Picture 1 Is a screenshot of GParted showing the new sizes of my root and home partitions. I removed the GParted CD from my CD-ROM drive and rebooted the PC to thankfully find all was well and no errors reported. Conclusion My PC is now running more smoothly. All I can say after all this is that I consider myself very lucky this time and I hope I learned some valuable lessons along the way. Provide feedback on this episode .…

HPR4347: "Of my country!" Brazil - in a Southern city viewing

לפני 3 ימים

—

This show has been flagged as Clean by the host. I’m glad I’m here with you! I'll tell my impressions on things of my Brazilian country. Pardon me for some high-volume transitions ! Trying and testing the brickabrackis ( possibilities ). Pleasing or not. Thanks! Topics: 1- Sistema Único de Saúde (the national health system) Works! Any citizen, any person, has access to health treatment: no payment, no check if the person has payed taxes on anything, if is a worker or not. Of course, waiting time might be a problem if it's not an urgency or emergency, and quality varies (as any service, paid or not), according to city (capital or country town, more structured or smaller cities), hospital, the specific doctor and support team etc. 2- Tap water The water from the tap is safe, recognized as drinking water (in my city, and maybe in many if not most). The water treatment company ("Sanepar") here even sells their water bottled, and sponsors events that distribute them (sports events) to show the quality. But people don't use to drink from the tap it directly. If they do not use a filter, it's common to buy water in 20 liters carboys (big plastic bottles, 20L is a bit more than 5 gallons) . I use this last option, but drink water under the shower also. Most people (that I know, of course) simply don't drink water ! I don't know. I don't understand how it is, but they don't drink water, not even a liter per day. Coffee and soda are the most common "substitutes". 3- Religion numbers Statistics about religion are very misleading. You can find different numbers but it's generally: more than half identifying as Catholics. More than 20% evangelical, 10% without religion. But those numbers say nothing about reality of what you find in the streets. Maybe because in some areas it's embarassing to identify as an atheist, as if you're immoral and cannot be trusted; so, people without religion simply say the religion of the family, or the generic "catholic, non-practicing". 4- Brazilian Law Our law is written and detailed. Everything you could want to know about our judicial system, our rights and etc. are explicit in laws; and our Constitution, in force since 1988, with more than 200 articles, guides all. The Supreme Court can make and change interpretations and, thus, issue binding decisions that are not seem in the law, but this is the exception. Cover of the official edition of the Brazilian Constitution in the English Language. (Source: https://www.stf.jus.br/arquivo/cms/legislacaoConstituicao/anexo/Brazil_Federal_Constitution_EC_125.pdf. Accessed on February 2025.) Most of the norms are federal and encompass the entire nation: it is a reason we are so "equal", in many senses, while living in a country with 212 million people (official estimation of IBGE, July 1st 2024 * ) and that represents 48% of the size of South America. 5- Now something very specific to my city, a capital city on the south of the country It's not expected to say Good morning when you cross with a stranger on the street. No Hello or Good morning to the bus driver also. I mean, a lot of people greet, but many don't and it's common to not do so. In many other parts of the country, of course, it's different. For example, I lived in a capital city on the north, and everybody expected you to say Good Morning! when entering an elevator in the morning, behavior that generally makes people think you're strange here in my southern city. If I ask for the name of a seller on a store, to be more polite saying his or her name occasionally if I am making a lot of questions and demanding more attention time, they ask, you're not from here are you? And I am. If anything here sounds not good, please reject and keep the good. It's only impressions that I wanted to share. Thank you. * This news in English: From: Agência IBGE.

HPR4342: How I use Git to blog on the web and gopherspace

לפני 10 ימים

—

This show has been flagged as Clean by the host. First, I create a Git repository some place on the server. This is the Git repo that's going to be populated with your content, but it doesn't have to be in a world-viewable location on your server. Instead, you can place this anywhere, and then use a Git hook or a cronjob to copy files from it to a world-viewable directory. I don't cover that here. I refer to this location as the staging directory. Next, create a bare repository on your server. In its hooks directory, create a shell script called post-receive: #!/usr/bin/bash # while read oldrev newrev refname do BR=`git rev-parse --symbolic --abbrev-ref $refname` if [ "$BR" == "master" ]; then WEB_DIR="/my/staging/dir" export GIT_DIR="$WEB_DIR/.git" pushd $WEB_DIR > /dev/null git pull popd > /dev/null fi done Now when you push to your bare repository, you are triggering the post-receive script to run, which in turn triggers a git pull in your staging directory. Once your staging directory contains the content you want to distribute, you can copy them to live directories, or you could make your staging directory live (remember to exclude the .git directory though), or whatever you want. For gopher, I create a file listing by date using a shell script: #!/usr/bin/bash SED=/usr/bin/sed DIR_BASE=/my/live/dir DIR_LIVE=blog DIR_STAGING=staging DATE=${DATE:-`date --rfc-3339=date`} for POST in `find "$DIR_BASE"/"$DIR_STAGING" \ -type f -name "item.md" -exec grep -Hl "$DATE" {} \;`; do POSTDIR=`dirname "$POST"` cp "$POST" "$DIR_BASE"/"$DIR_LIVE"/`basename $POSTDIR`.txt echo -e 0Latest'\t'../"$DIR_LIVE"/`basename $POSTDIR`.txt > /tmp/updater.tmp echo -e 0"$DATE" `basename $POSTDIR`'\t'../"$DIR_LIVE"/`basename $POSTDIR`.txt \ >> /tmp/updater.tmp "${SED}" -i "/0Latest/ r /tmp/updater.tmp" "$DIR_BASE"/date/gophermap "${SED}" -i '0,/0Latest/{/0Latest/d;}' "$DIR_BASE"/date/gophermap /usr/bin/rm /tmp/updater.tmp done Provide feedback on this episode .…

HPR4341: Transferring Large Data Sets

לפני 11 ימים

—

This show has been flagged as Clean by the host. Transferring Large Data Sets Very large data sets present their own problems. Not everyone has directories with hundreds of gigabytes of project files, but I do, and I assume I'm not the only one. For instance, I have a directory with over 700 radio shows, many of these directories also have a podcast, and they also have pictures and text files. Doing a properties check on the directory I see 450 gigabytes of data. When I started envisioning Libre Indie Archive I wanted to move the directories into archival storage using optical drives. My first attempt at this didn't work because I lost metadata when I wrote the optical drives since optical drives are read only. After further work and study I learned that tar files can preserve meta data if they are created and uncompressed as root. In fact, if you are running tar as root preserving file ownership and permissions is the default. So this means that optical drives are an option if you write tar archives onto the optical drives. I have better success rates with 25 GB Blue Ray Discs than with the 50 GB discs. So, if your directory breaks up into projects that fit on 25 GB discs, that's great. My data did not do this easily but tar does have an option to write a data set to multiple tar files each with a maximum size, labelling them -0 -1, etc. When using this multi volume feature you cannot use compression. So you will get tar files, not tar.gz files. It's better to break the file sets up in more reasonable sizes so I decided to divide the shows up alphabetically by title, so all the shows starting with the letter a would be one data set and then down the alphabet, one letter at a time. Most of the letters would result in a single tar file labeled -0 that would fit on the 25 GB disc. Many letters, however, took two or even three tar files that would have to be written on different disks and then concatenated on the primary system before they are extracted to the correct location in primaryfiles. There is a companion program to tar, called tarcat, that I used to combine 2 or 3 tar files split by length into a single tar file that could be extracted. I ran engrampa as root to extract the files. So, I used a tar command on the working system where my Something Blue radio shows are stored. Then I used K3b to burn these files onto a 25 GB Blu Ray Disc carefully labeling the discs and writing a text file that I used to keep up with which files I had already copied to Disc. Then on the Libre Indie Archive primary system I copied from the Blu Ray to the boot drive the file or files for that data set. Then I would use tarcat to combine the files if there was more than one file for that data set. And finally I would extract the files to primaryfiles by running engrampa as root. Now I'm going to go into details on each of these steps. First make sure that the Libre Indie Archive program, prep.sh, is in your home directory on your workstation. Then from the data directory to be archived, in my case the something_blue directory run prep.sh like this. ~/prep.sh This will create a file named IA_Origin.txt that lists the date, the computer and directory being archived, and the users and userids on that system. All very helpful information to have if at some time in the future you need to do a restore. Next create a tar data set for each letter of the alphabet. (You may want to divide your data set in a different way.) Open a terminal in the same directory as the data directory, my something_blue directory, so that ls displays something_blue (your data directory). I keep the Something Blue shows and podcasts in subdirectories in the something_blue directory. Here's the tar command. Example a: sudo tar -cv --tape-length=20000000 --file=somethingblue-a-{0..50}.tar /home/larry/delta/something_blue/a* This is for the letter a so the --file parameter includes the letter a. The numbers 0..50 in the squirelly brackets are the sequence numbers for the files. I only had one file for the letter a, somethingblue-a-0.tar. The last parameter is the source for the tar files, in this case /home/larry/delta/something_blue/a* All of the files and directories in the something_blue directory that start with the letter a. You may want to change the --tape-length parameter. As listed it stores up to 19.1 GB. The maximum capacity of a 25 GB Blu-ray is 23.3GB for data storage. Example b: For the letter b, I ended up with three tar files. somethingblue-b-0.tar somethingblue-b-1.tar somethingblue-b-2.tar I will use these files in the example below using tarcat to combine the files. I use K3b to burn Blu-Ray data discs. Besides installing K3b you have to install some other programs and then there is a particular setup that needs to be done including selecting cdrecord and no multisession. Here's an excellent article that will go step by step through the installation and setup. How to burn Blu-ray discs on Ubuntu and derivatives using K3b? https://en.ubunlog.com/how-to-burn-blu-ray-discs-on-ubuntu-and-derivatives-using-k3b/ I also always check Verify data and I use the Linux/Unix file system, not windows which will rename your files if the filenames are too long. I installed a Blu-Ray reader into the primary system and I used thunar to copy the files from the Blu-Ray Disc to the boot drive. In the primaryfiles directory I make a subdirectory, something_blue, to hold the archived shows. If there is only one file, like in example a above, you can skip the concatenation step. If there is more than one file, like Example b above, you use tarcat to concatenate these files into one tar file. You have to do this. If you try to extract from just one of the numbered files when there is more than one you will get an error. So if I try to extract from somethingblue-b-0.tar and I get an error it doesn't mean that there's anything wrong with that file. It just has to be concatenated with the other b files before it can be extracted. There is a companion program to tar called tarcat that should be used to concatenate the tar files. Here's the command I used for example b, above. tarcat somethingblue-b-0.tar somethingblue-b-1.tar somethingblue-b-2.tar > sb-b.tar This will concatenate the three smaller tar files into one bigger tar file named sb-b.tar In order to preserve the meta data you have to extract the files as root. In order to make it easier to select the files to be extracted and where to store them I use the GUI archive manager, engrampa. To run engrampa as root open a terminal with CTRL-ALT t and use this command sudo -H engrampa Click Open and select the tar file to extract. Then follow the path until you are in the something_blue directory and you are seeing the folders and files you want to extract. Type Ctrl a to select them all. (instead of the something_blue directory you will go to your_data directory) Then click Extract at the top of the window. Open the directory where you want the files to go. In my case, primaryfiles/something_blue Then click Extract again in the lower right. After the files are extracted go to your data directory in primaryfiles and check that the directories and files are where you expect them to be. You can also open a terminal in that directory and type ls -l to review the meta data. When dealing with data chunks sized 20 GB or more each one of these steps takes time. The reason I like using an optical disk backup to transfer the files from the working system to Libre Indie Archive is because it gives me an easy to store backup that is not on a spinning drive and that cannot be overwritten. Still optical disk storage is not perfect either. It's just another belt to go with your suspenders. Another way to transfer directories into the primaryfiles directory is with ssh over the network. This is not as safe as using optical disks and it also does not provide the extra snapshot backup. It also takes a long time but it is not as labor intensive. After I spend some more time thinking about this and testing I will do a podcast about transferring large data sets with ssh. Although I am transferring large data sets to move them into archival storage using Libre Indie Archive there are many other situations where you might want to move a large data set while preserving the meta data. So what I have written about tar files, optical discs, and running thunar and engrampa as root is generally applicable. As always comments are appreciated. You can comment on Hacker Public Radio or on Mastodon. Visit my blog at home.gamerplus.org where I will post the show notes and embed the Mastodon thread for comments about thie podcast.

This show has been flagged as Clean by the host. Civilization IV added some new Victory types, and I decided to illustrate one of them, the Culture victory, by going through an example of achieving this, the Culture victory.

HPR4338: 328eforth

לפני 16 ימים

Review of the book the Arduino controlled by eforth by dr chen-hanson ting published in 2018 written by chen-hanson ting Late Dr. ting was a chemist turned engineer. he earned a phd in chemistry at the U of Chicago in 1965. taught chemistry in Taiwan until 1975. became a firmware engineer until hI retirement in 2000. he was a forth advocate for more than 50 years, especially a forth called eforth that has been ported to many devices, including the micro chip atmega 328 found on the arduino uno board. I found this book while searching for forths for the arduino uno boards. the source code and documentation for eforth is available in a lot of places I will put a few links in the show notes. I believe I mentioned this forth in an earlier hpr where I talked about choosing a forth. forth interest group https://forth.org https://wiki.forth-ev.de https://chochain.github.io (pdf) When I first encountered dr tings forth for arduino I was interested for one reason, it was easily assembled using avra, the gnu port of the atmel assembler. this was nice because using atmels (now microchips) assemblers on Linux required installing wine and installing wine, in the past, on a 64 bit Slackware meant installing 32 bit libraries to have a multI lib Slackware. ( that not an issue now). assembling the forth code in avra is quick, its only a little bit over 5k in size in the end. After playing with eforth for a while I became frustrated because I could create new words in the dictionary and the examples ran fine, but nothing persisted across reboot. so I dropped eforth and ended up using flashforth, which is a great, robust full featured forth. I still recommend flashforth if your starting out with forth on a microcontroller its solid software with good documentation. At the end of last year I thought it would be fun to write my own forth. and after looking into doing that I revisited 328eforth and thought, no how about I fix the problems with eforth on the arduino. so I dug out the book and began reading. Jones forth port at https://ratfactor.com/nasmjf The book has 6 parts. part 1 is dr tings musings on how he ended up creating 328eforth. part 2 explains installing eforth. the 3rd part begins exercising the arduino board using forth in the interactive interpreter. part 4 explains 328eforth implementation and design decisions. part 5 is the full commented source code of 328eforth and, this is the best part, dr tings explanation of what is going on in the code broken down by functional sections. a gold mine of information! part 6 conclusions The last part is his conclusions and examples to learn forth. This is a great free software project. nothing is hidden. it is accessible to anybody who would take the time to read and dig into the code. its makes assembly language much less dark and foreboding. I'll finish by reading a couple of paragraphs from dr tings book dr ting concludes: People using computers are trained to be slaves. You are taught to push certain buttons, and your are taught to push certain keys. Then, you get employed to push buttons and keys to work as slaves. Computers, programming languages, and operating systems are made complicated to enslave…

In here: 1- Carrying weight more safely - When picking up weight in front of your body, embrace the core (tighten the abdomen); - it gives you more stability, so you are more capable to do the task. 2- Microphone types a) by connection i) USB: connects directly to the computer, in the universal serial bus port. Plug and use! ii) XLR: needs a USB audio interface , with XLR input, to connect to the computer. There are more options of microphones and, if you can spend on an interface, quality is generally better. XLR connectors: female (left) and male. ( Image by Michael Piotrowski / Wikimedia Commons – CC BY-SA 3.0 .) b) by diaphragm i) condenser: captures the voice in more detail, with deeper bass, more detailed treble… Most of the USB microphones uses this technology. As a disadvantage, they catch even minimal sound details of the environment, vibrating with little sound waves around, even distant. That’s why you might get as recording result the clear details of noise from the street, or reverberation (echo) of an untreated room if you use it without the best environment. (If it’s ok for you even in these situations, it’s a merit of other factors, not a merit of the condenser diaphragm) . Usage : A favorite of singers in studio, among several other applications. As you can see on videos of professionals singing, one don’t talk on top of it (which might produce a low and undesired muffled sound) but on the side — and on the correct side, because most models of microphones have a cardioid pollar pattern. A side-adress microphone (captures the sound from one specific side), condenser-type. (Image by Arthur Fox / https://mynewmicrophone.com/diaphragm.) ii) dynamic: responds to the audio source (voice, instrument) very close to the diaphragm, do not capture sound more than some centimeters (or some inches) away. It’s the best for amateur use, or in a room without acoustic treatment. Usage : Musicians performing live use dynamic microphones so the instruments (and crowd) around don’t get their sound amplified by this artist’s microphone. Radios prefer dynamic mics, because it goes to a more impactful voice, rejects eventual sounds from noisy mixers or keyboards nearby that the radio host might be operating. A top-adress microphone (captures the sound from the top), dynamic-type. (Image by Arthur Fox / https://mynewmicrophone.com/diaphragm.) The RE20 from Electro-Voice (not the photo above) is a favorite of radio stations, in part for being dynamic, in part for reducing the proximity effect (that is, the sound “exploding” when the source gets too near to the capsule) because of its technology, named Variable-D. A word about captation pattern (no, the name is polar pattern): it says about the directional response. For example, some are omnidirectional (captures sound equally from all the sides); most of them are cardioid, capturing the sound coming from the front (the speaker, the instrument directed to it), but rejects sound from…
