sorry to bug but, do you.... have... bananabay that is NOT missing textures and other problems for SFM...? I just spent HOURS trying to make it behave, I even fucked around with file editing shit to try and make it work, I am a broken man and trying to use hammer is just one thing to many just for a goddamn decent beach map ;n;

Have you tried repacking the map in TF2? I don’t know the science of it and people have explained it on the SFM discussions groups if you want to know how/why it works, but this is the command that I put into the TF2 console to first see if I can get a map to load into SFM if it won’t:

bsp_repack -nocompress maps\[MAP GOES HERE].bsp maps\[MAP GOES HERE]_repack.bsp

Note that I put _repack as my suffix but you can put _edit or whatever you need just to differentiate it from your original (e.g. pl_snowycoast becomes pl_snowycoast_repack). Then you’ll take that from your TF2 maps folder and drop it off somewhere in an SFM maps folder. 

Note that you also have to have the map somewhere in your TF2 maps folder already (preferably not your downloads/maps folder).

You want to avoid renaming filenames for maps in Windows Explorer as much as possible, but this above method allows you to change the name without having an issue. A few friends a while back passed me an SFM-converted version of a map that I had renamed before plopping it into SFM but it didn’t like that, nor did it like being changed back, so I redownloaded it and didn’t touch the filename and it worked. 

If the repacking doesn’t work (and I recommend trying the repack method anyway for your own education because SFM is Not Nice) you can download the Jungle Inferno maps from the description of this workshop entry here.

MySQL Connector/Python 8.0.21 has been released

Dear MySQL users, MySQL Connector/Python 8.0.21 is the latest GA release version of the MySQL Connector Python 8.0 series. The X DevAPI enables application developers to write code that combines the strengths of the relational and document models using a modern, NoSQL-like syntax that does not assume previous experience writing traditional SQL. To learn more about how to write applications using the X DevAPI, see http://dev.mysql.com/doc/x-devapi-userguide/en/ For more information about how the X DevAPI is implemented in MySQL Connector/Python, and its usage, see http://dev.mysql.com/doc/dev/connector-python Please note that the X DevAPI requires at least MySQL Server version 8.0 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see http://dev.mysql.com/doc/refman/8.0/en/document-store.html To download MySQL Connector/Python 8.0.21, see the “General Availability (GA) Releases” tab at http://dev.mysql.com/downloads/connector/python/ Enjoy! Changes in MySQL Connector/Python 8.0.21 (2020-07-13, General Availability) Functionality Added or Changed * Implemented context managers to define the runtimecontext to establish when executing a with statement. Itwas added to the Connection and Cursor objects in theclassic protocol, and to Session in the X DevAPI. Thanksto WEN-FENG SHIH for the patch. (Bug #19586444, Bug#71663, Bug #28779784, Bug #89113) * Added compression support to X Protocol connections.Supported compression algorithms are zlib/deflate andlz4. Specifically, the supported algorithms (in order ofpreference) are lz4_message and deflate_stream. Thecompression threshold is set at 1000 bytes.A new compress X DevAPI connection option accepts eitherrequired, disabled, or preferred (default). + preferred: If Connector/Python and the server cannotreach consensus on algorithm or styles, then nocompression is used; and this is logged. + required: Like preferred, except the connection isterminated with an error if the connector and serverare unable to reach agreement. + disabled: Compression is not used. Bugs Fixed * The connect_timeout option applied to all blocking socketoperations but now properly only applies to the timeoutwhen establishing the connection. (Bug #30996790) * In X DevAPI implementation, an error was raised whenusing the fractional part in DATETIME types. The error:“ValueError: Datetime mapping scenario unhandled” (Bug#30950184) * Because MySQL stores TEXT types as BLOB and JSON asLONGBLOB, the TEXT and JSON types are now converted tostr and the rest of the BLOB types as bytes. Previously,as an example, a column of type TEXT that only containeddigits was read as type=integer by Connector/Python. (Bug#29808262, Bug #95437) * Connector/Python assumed that MySQL libraries were underlib/ when compiling the C extension, but now uses themysql_config flags which adds the correct include andlibraries paths. Thanks to Daniël van Eeden for thepatch. (Bug #29181907, Bug #93846) On Behalf of Oracle/MySQL Engineering Team, Balasubramanian Kandasamy https://insidemysql.com/mysql-connector-python-8-0-21/

System administration command. Manipulate logfiles according to commands given in config_files.

Options

-d, --debug Debug mode. No changes will be made to logfiles. -f, --force Force rotation of logfiles. -h, --help Describe options. -m command, --mail command Use the specified command to mail logfiles. The default command is /bin/mail -s. -s file, --state file Save state information in file. The default is /var/lib/logrotate.status. --usage Show syntax and options. -v, --verbose Describe what is being done and what logfiles are affected.

Configuration Commands

Logrotate directives may appear on their own or as part of logfile definitions—instructions for specific logfiles. You may use wildcards to specify those files. Enclose directives for logfile definitions in a beginning and ending curly brace. For example: compress /var/log/messages { rotate 5 weekly } compress Compress old versions of logfiles with gzip. compresscmd command Use command to compress logfiles. Default is gzip. compressext extension Append filename extension to compressed files instead of the compress command's default. compressoptions options Specify options to pass to the compress command. Default for gzip is -9 for maximum compression. copy Copy logfile, but do not change the original. copytruncate Copy logfile, then truncate it in place. For use with programs whose logging cannot be temporarily halted. create [permissions] [owner] [group] After rotation, re-create logfile with the specified permissions, owner, and group. permissions must be in octal. If any of these parameters is missing, the logfile's original attributes will be used. daily Rotate logfiles every day. delaycompress Don't compress logfile until the next rotation. endscript End a postrotate or prerotate script. extension extension Give rotated logfiles the specified extension. Any compression extension will be appended to this. firstaction May only be used as part of a logfile definition. Begin a shell script to execute once if any files match.

Guide to add zRAM on the Synology DiskStation DS212j

My Synology DiskStation DS212j has gotten slower over the years ever since I bought in 2012. DSM operating system security and software upgrades introduced feature bloat that required more memory and caused memory to page to disk. Wikipedia gives an amazing overview of why paging is bad and why zRAM is amazing for memory constrained PCs.

zram (also called zRAM and, initially, compcache) is a Linux kernel feature that provides a form of virtual memory compression. zram increases performance by avoiding paging to disk and using a compressed block device in RAM instead, inside which paging takes place until it is necessary to use the swap space on a hard disk drive. Since using zram is an alternative way to provide swapping on RAM, zram allows Linux to make a better use of RAM when swapping/paging is required, especially on older computers with less RAM installed.

Pretty cool, huh? The Android community often uses zRAM as a way to bring back older devices back to life and I figured I could do the same with my aging DiskStation that only came with 256MB of RAM compared to the more recent DS216 that comes with twice that at 512MB.

I successfully compiled and added the zRAM module to my DS212j and wanted to share the steps. My DS212j uses the Linux kernel 2.6.32 so this guide should be applicable to any Synology DS that uses the same kernel.

Setting up the DSM 6.1 Tool Chain

Synology has provided excellent documentation on how to compile kernel modules. You should follow their tutorial on how to setup the toolkit to compile the kernel.

Steps for the DS212j are roughly:

Setup toolkit: mkdir -p /toolkit

cd /toolkit

git clone https://github.com/SynologyOpenSource/pkgscripts-ng.git

cd /toolkit/pkgscripts-ng/

./EnvDeploy -v 6.1 -p 6281

Compiling the 2.6.32 Kernel

You will need to follow the Synology documentation to compile kernel modules here in order to build the LZO kernel module. This is a dependent kernel module for zRAM.

Steps are roughly:

Download the kernel source for the closest branch that is currently deployed on your Synology: https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/

Extract the source to /toolkit/build_env/ds.x64-6.1/root/

Enter the tool chain chroot: chroot /toolkit/build_env/ds.x64-6.1 /bin/bash

cd root/linux-2.6.32

cp synoconfigs/88f6281 .config

export ARCH="arm"

export CROSS_COMPILE="/usr/local/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-"

make oldconfig

make menuconfig

Build LZO modules because they’re dependencies for zRAM. Enter Cryptographic API to select LZO compression algorithm as a module. Exit and save.

make prepare

make modules

Copy lzo_compress.ko, lzo_decompress.ko, lzo.ko to your Synology

Compiling the Compcache Kernel Module

I have successfully compiled the Compcache 0.6.2 kernel module and gotten it to work with the stock 2.6.32 kernel. The latest version doesn’t seem to work so we’re going to stick with 0.6.2 where we will follow the Compcache documentation here.

cd /root/

Download Compcache 0.6.2 module source: wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/compcache/compcache-0.6.2.tar.gz

tar -xzf compcache-0.6.2.tar.gz

cd compcache-0.6.2

export KERNEL_BUILD_PATH=/root/linux-2.6.32

make

Copy ramzswap.ko to your Synology

Installation

Copy kernel modules to Synology DSM

Test kernels by inserting them

/sbin/insmod /lib/modules/lzo_decompress.ko /sbin/insmod /lib/modules/lzo_compress.ko /sbin/insmod /lib/modules/lzo.ko /sbin/insmod /lib/modules/ramzswap.ko disksize_kb=131072 /sbin/swapon /dev/ramzswap0 -p 5

Enable swap with: /sbin/swapon /dev/ramzswap0 -p 5

Verify everything worked by checking dmesg for errors

nschimme@NilsDiskStation:~$ dmesg | grep -E "(ramzswap|lzo)" [ 100.500000] alg: No test for lzo (lzo-generic) [ 100.550000] ramzswap: num_devices not specified. Using default: 1 [ 100.550000] ramzswap: /dev/ramzswap0 initialized: disksize_kb=131072 [ 100.560000] ramzswap: Invalid ioctl 21297 [ 101.560000] Adding 131064k swap on /dev/ramzswap0. Priority:5 extents:1 across:131064k SS nschimme@NilsDiskStation:~$

Add above insmod/swapon commands to /etc/rc.local to make the changes permanent

zRAM Results

It’s super effective! I’ve noticed that there was roughly ~100MB of paged memory usually and I’ve managed to get it all to fit within ~30MB of compressed memory space rather than going down to the hard drive. Responsiveness in the DSM OS has greatly improved as a result.
