Why Microsoft Windows sucks? (This article is Work In Progress, comments are warmly welcomed, read ALL before commenting. Email => echo aUB0ZXJyeS5pbQo= | base64 -d ! I will be more than happy to improve this article. Please DO read the conclusion. DO NOT take it for granted, it's not simply debasing Windows. Win-Win situation is something I would like to see.) Simply keep /home on a separate partition (Btrfs => subvolume / LVM => logical volume). NOTE: remember to tar /etc and where you put custom stuff in case you need them, also look into /var for run time data like mysql, etc. under /var/lib). Also /opt and /usr/local for software compiled from source. Backup: tar ~ or preferably $HOME directly (of course you can use | & send it over the network using netcat and/or via SSH without consuming extra local disk space. Use rsync to copy it to external HDD or to NFS on NAS via SSH. Examples:
It's so easy to switch distributions or replace your hard disk. For apps, APTonCD (for Debian based distros) offers the backup to all installed packages on the fly, unless you clean all the package caches in /var/cache/apt/archives by using apt-get clean command. Note: The UUID may change if you replace any hardware, for example a larger and faster Hard Disk. Remember to change the UUID (use blkid) reference in /boot/grub/menu.lst (/boot/grub/grub.cfg for GRUB2) and /etc/fstab. Labelling file system is also a good idea. To reinstall a Debian based Linux distro, simply export all installed packages to a list by executing the command on the source PC: sudo dpkg --get-selections > pkg.list Restore all packages on the newly installed destination PC: sudo dpkg --set-selections < /path/to/pkg.list sudo apt-get dselect-upgrade Grab a tea or coffee, it's done when you are back! Note: Be careful when using this migration method when moving between different architecture (e.g. x86->x86_64). For Arch Linux users, check Backing up and retrieving a list of installed packages Mac OS XMigration Assistant offers pain free migration over wireless network or FireWire! Since 10.5 Leopard it supports Time Machine backup or other disk (USB), to another Mac. Imagine the use case => you replace the internal Hard Drive with a bigger and faster one. Re-install OS X and plug the old HD to your Mac via USB, all user settings and apps can be migrated seamlessly. Even dummies can do this. This should profit from its UNIX ancestors. In real world, I had replaced my Macbook HDD (80G Seagate Momentus 5400.3) because it's slow and small capacity. I replaced it with a Seagate Momentus 7200.4 320G. What I did was replace the Hard Drive according to the official guide, made a external USB HD with the old HD, reinstalled Mac OS X. Then plug the external HD during the 1st boot, Migration Assistant will pop up and ask you to migrate all user settings, Applications and other data. Cool! I went out for a walk and then it's done. Of course you can use tools like CCC to copy the whole OS over to the new HD. I just don't bother, I want a fresh OS X install. Update: I bought a MacBook Air for TAOTAO, it is running OS X 10.8 (now 10.9). I migrated user settings and data from 10.7 Time Machine backup, everything works out-of-the-box as if I am using the old MacBook. The most incredible part is it even took care of packages compiled and installed via Homebrew. Although I had to install Xcode Command Line Tools before I could use it. This is productivity!!! NOTE: I had to install a mising dependency - libpng (brew doctor told me) before I can use brew. WindowsUpdate: The new Windows Easy Transfer tool in Windows 7 works pretty well out of the box if you migrate from Windows 7 to Windows 7. However, it doesn't work with previous versions (between different Windows versions)...Pain in the ass - Windows patching (hot fixes/service packs, leftovers and reboots)
If we install Microsoft Windows from scratch on new hardware, at least 2-4 hours will be wasted on applying Windows Updates, along with endless restart cycles. Update leftover, garbages, ignore this if you have a big enough disk. While I think nobody likes to keep junks at home, right? So you need to manually delete the craps:
Linux In most of the modern Linux distributions, package updates, security patches (errata) and even new versions of Linux kernel (pre-compiled) will be push to end-users from official repositories (if configured). With Ksplice some Linux distributions (Free on Fedora and Ubuntu) is capable of applying security patches to the running kernel without rebooting. This is mission impossible for Windows n the foreseeable future. Update: Now we have kpatch, and live patching (kernel/livepatch) is in the Linux Kernel mainline since 4.0. Mac OS X Most of the important patches can be pushed to every Mac OS X installation. Even dummies will be able to upgrade their Mac OS X without difficulties. Of course, standalone/combo patches are always available on apple.com File System
I am used to the *NIX file system and directory structure. As I am a hardcore user of GNU/Linux (Since 2001) combined with Mac OS X. *NIX has a simple and clear directory structure, everything is under Root /, user profiles are under ~ or $HOME clean and tidy, easy to manage. Less fragmentation compared with FAT32/NTFS. Although officially, ext{2,3} is supposed to be fragment-free. But why there is still e2defrag? And in ext4, there is an online defrag tool e4defrag. The so-called next generation Linux file system Btrfs has online engagement function:) I am NOT 100% sure about this... (@WIP) Once M$FT's WinFS in 'Longhorn' - code name for Vista drew some of my attention. But the disappointing truth was that there was no such WinFS in Vista or Server 2008. Only a higher version of NTFS. NTFS is all right. However, it is definitely NOT able to compete with ext4, Btrfs or ZFS... NOTE: It's easier to take advantage of RAID on Linux because software-based RAID support is built-in (md, LVM, Btrfs / ZFS). The best practice is to combine RAID (all about performance and data reliability) - MD (multiple devices / mdadm) + LVM (about storage management and file system). Btrfs (file system with built-in volume management)is the future of Linux file system, often considered an equivalent of ZFS (on Solaris and FreeBSD). It's really cool! Try it out and see yourself, you'll love it! But DO remember to use raid1 or raid10 for data (metadata is by default replicated across drives) backup your data!!! => READ this => Btrfs TipsUpgrade (rolling releases)
We all know that some great GNU/Linux distros like Gentoo, Arch Linux and Debian sid (close but not full rolling release) are rolling releases. They have the concept of rolling upgrade which means, whenever there is a new release or version, we can just upgrade on top of the existing installation, all configurations and software packages will be upgraded automatically, dependencies will be resolved by package management. However, do prepare to fix endless problems, for example every time you don't upgrade Arch Linux after a few weeks;-) However, whenever we upgrade Windows nothing seems to be smooth. Mac OS X does a relatively good job as well, upgrade is an easy job. Migrating user settings/data is an easy job via Migration Assistant. Stability, Reliability and SecurityI don't want to discuss any more about the stability, reliability and security difference between *NIX and Windows. We all know the story. *NIX and Windows, totally different. BSOD (Blue Screen of Death) & System HangOne more thing about bloody Windows, BSOD. System hang! There is no way to recover unless hard reset, power off and on. I have never experienced any system hang on Mac OS X so far, 3+ years (I did experienced a few unexpected shutdown and a couple of system hangs since 10.6 Snow Leopard). Aqua on top of Darwin seems to be well optimized, very stable. Sometimes X11 (also known as X Window System, X) on Linux crashes or hangs. I can still kill the x session and restart it. The rest of the system is still alive. Login via either pseudo consoles or SSH to write back cache to disk and try to do backup unsaved work, use the Magic SysRq key (Alt + R, E, I, S, U B, reverse BUSIER) to safely reboot. I have experienced many unexplained Linux system hangs (mostly on desktops / laptops) over the years, most of them were caused by my own silliness (I don't want to talk about this here anyway;-) Fortunately I didn't lose any important data because I use Chrome sync, Google Docs (Drive now) and Dropbox to push everything into the cloud. Also, do remember to use tmux (byobu / screen) when doing administration jobs on remote host, you know why;-) Internet Explorer (devil)IE seems to become a part of the fatty Windows kernel now, at least a very important part of the whole operating system. IE can be a severe security threat to Windows because of Browser Help Object. It is easy to inject malicious code by making use of the BHO, and run the codes inside other processes. What I can't understand is why Microsoft allows IE to be such a big potential threat to the whole operating system. The architecture of Windows is really ridiculous. I have never heard that browser can cause such a big risk in *NIX world. I did remember there were a lot of buffer/stack overflow or things like that for Linux, and by doing that someone can get root privilege. Most of them were kernel or device, device driver related. Browser? Never heard of, maybe I am ignorant... So, who is to blame? Microsoft Windows architect? I believe IE is losing its market share anyway. Although a lot of Internet banking or web apps still rely on ActiveX, as a result they are only compatible with IE and Windows(Run ies4linux, IE in WINE, I don't think it's a good workaround, we don't count running Windows in Virtual Machines either). I can't say IE is totally crap, but in fact it is very stupid and crappy. I have to use it because of web conferencing tool, Siebel CRM and netbank. But I normally run IE in a Guest Windows XP running in VirtualBox or VMWare Workstation/Fusion. Better choice out there in the market: Chrome, Chromium, Firefox, Opera. RegistryThe concept Registry should be a great idea and innovation, but Microsoft's implementation turned out to be crap. Back in Windows 98/98SE era, Registry was easy to get overstaffed and causes Windows to crash a lot. It's still a core of the Windows OS, even Windows Mobile. So many garbages in registry, normally don't try to clean up, just forget about it. I prefer text file based configuration implementation in Linux (in /etc). That's far more reliable and straightforward. No native Multi-Workspace (virtual desktop)
