  • Perfect is the enemy of “Good Enough”

    - by Daniel Moth
    This is one of the quotes that I was against, but now it is totally part of my core beliefs: "Perfect is the enemy of Good Enough" Folks used to share this quote a lot with me in my early career and my frequent interpretation was that they were incompetent people that were satisfied with mediocrity, i.e. I ignored them and their advice. (Yes, I went through an arrogance phase). I later "grew up" and "realized" that they were missing the point, so instead of ignoring them I would retort: "Of course we have to aim for perfection, because as human beings we'll never achieve perfection, so by aiming for perfection we will indeed achieve good enough results". (Yes, I went through a smart ass phase). Later I grew up a bit more and "understood" that what I was really being told is to finish my work earlier and move on to other things because by trying to perfect that one thing, another N things that I was responsible for were suffering by not getting my attention - all things on my plate need to move beyond the line, not just one of them to go way over the line. It is really a statement of increasing scale and scope. To put it in other words, getting PASS grades on 10 things is better than getting an A+ with distinction on 1-2 and a FAIL on the rest. Instead of saying “I am able to do very well these X items” it is best if you can say I can do well enough on these X * Y items”, where Y > 1. That is how breadth impact is achieved. In the future, I may grow up again and have a different interpretation, but for now - even though I secretly try to "perfect" things, I try not to do that at the expense of other responsibilities. This means that I haven't had anybody quote that saying to me in a while (or perhaps my quality of work has dropped so much that it doesn't apply to me any more - who knows :-)). Wikipedia attributes the quote to Voltaire and it also makes connections to the “Law of diminishing returns”, and to the “80-20 rule” or “Pareto principle”… it commonly takes 20% of the full time to complete 80% of a task while to complete the last 20% of a task takes 80% of the effort …check out the Wikipedia entry on “Perfect is the enemy of Good” and its links. Also use your favorite search engine to search and see what others are saying (Bing, Google) – it is worth internalizing this in a way that makes sense to you… Comments about this post by Daniel Moth welcome at the original blog.

  • Software Center doesn't show files installed

    - by postfuturist
    When I install a program in the Software Center that happens to install a menu option, it is discoverable through the menu, but if it is a package that is documentation, or command-line only, there is no simple way to discover how to actually access the content / software. Is there a way in the Software Center to see what files or executables were installed with a particular package so I can actually use / read it?

  • Do any OO languages support a mechanism to guarantee an overriden method will call the base?

    - by Aaron Anodide
    I think this might be a useful language feature and was wondering if any languages already support it. The idea is if you have: class C virtual F statement1 statement2 and class D inherits C override F statement1 statement2 C.F() There would be a keyword applied to C.F() such that removing the last line of code above would cause a compiler error because it's saying "This method can be overridden but the implementation here needs to run no matter what".

  • How can I set up the Trusty Desktop ISO for preseeding?

    - by user288087
    With Precise, I used to create a USB stick using the so-called "Alternate" installer DVD with my own preseed.txt, update isolinux/txt.cfg with a new menu item that would pass my preseed file on the command line, and watch as the installer happily did all the right things to create a Ubuntu install on the hard drive of the machine I booted. With Trusty, the 'alternate' image has disappeared. Is it still possible to preseed a Trusty install, and if so, how do I get the d-i/ubiquity system to use my preseed file?

  • I'm looking to learn how to apply traditional animation techniques to my graphics engine - are there any tutorials or online-resources that can help?

    - by blueberryfields
    There are many traditional animation techniques - such as blurring of motion, motion along an elliptical curve rather than a straight line, counter-motion before beginning of movement - which help with creating the appearance of a realistic 3D animated character. I'm looking to incorporate tools and short cuts for some of these into my graphics engine, to make it easier for my end users to use these techniques in their animations. Is there a good resource listing the techniques and the principles behind them, especially how they might apply to a graphics engine or 3D animation?

  • How do I control how often search engines visit my site?

    - by Nick
    I've been using the following line in the <head> of my sites for years: <meta name="revisit-after" content="3 days" /> I recently discovered that it's not one of the meta tags that Google understands, which I take to mean that there's no point in including it, and that it's been doing no good at all for years. How often do search engines crawl a website by default, and what reliable ways are there to increase or decrease that frequency?

  • Why can't Ubuntu find an ext3 filesystem on my hard-drive?

    - by urig
    This question is related to this question: Not enough components to start the RAID array? I'm trying to retrieve data from a "Western Digital MyBook World Edition (white light)" NAS device. This is basically an embedded Linux box with a 1TB HDD in it formatted in ext3. It stopped booting one day for no apparent reason. I have extracted the HDD from the NAS device and installed it in a desktop machine running Ubuntu 10.10 in the hope of accessing the files on the drive. I have followed instructions in this forum post, intended to mount the drive through Terminal: http://mybookworld.wikidot.com/forum/t-90514/how-to-recover-data-from-wd-my-book-world-edition-nas-device#post-976452 I have identified the partition that I want to mount and recover files from as /dev/sd4 by running "fdisk -l" and getting this: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0001cf00 Device Boot Start End Blocks Id System /dev/sdb1 5 248 1959930 fd Linux raid autodetect /dev/sdb2 249 280 257040 fd Linux raid autodetect /dev/sdb3 281 403 987997+ fd Linux raid autodetect /dev/sdb4 404 121601 973522935 fd Linux raid autodetect// When I try to mount using: "mount -t ext3 /dev/sdb4 /media/xyz" I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so And "dmesg | tail" shows me: [ 15.184757] [drm] Initialized nouveau 0.0.16 20090420 for 0000:01:00.0 on minor 0 [ 15.986859] [drm] nouveau 0000:01:00.0: Allocating FIFO number 1 [ 15.988379] [drm] nouveau 0000:01:00.0: nouveau_channel_alloc: initialised FIFO 1 [ 16.353379] EXT4-fs (sda5): re-mounted.

I guess that last line is the punch line :) Why can't it find the ext3 filesystem on my drive? What do I need to do to mount this partition and copy its contents? Does it have anything to do with the drive being part of a RAID Array (see question mentioned above)? Many thanks to any who can help.

  • Help writing server script to ban IP's from a list

    - by Chev_603
    I have a VPS that I use as an openvpn and web server. For some reason, my apache log files are filled with thousands of these hack attempts: "POST /xmlrpc.php HTTP/1.0" 404 395 These attack attempts fill up 90% of my logs. I think it's a WordPress vulnerability they're looking for. Obviously they are not successful (I don't even have Wordpress on my server), but it's annoying and probably resource consuming as well. I am trying to write a bash script that will do the following: Search the apache logs and grab the offending IP's (even if they try it once), Sort them into a list with each unique IP on a seperate line, And then block them using the IP table rules. I am a bash newb, and so far my script does everything except Step 3. I can manually block the IP's, but that's tedious and besides, this is Linux and it's perfectly capable of doing it for me. I also want the script to be customizable so that I (or anyone else who wants to use it) can change the variables to suit whatever situation I/they may deal with in the future. Here is the script so far: #!/bin/bash ##IP LIST GENERATOR ##Author Chev Young ##Script to search Apache logs and list IP's based on custom filters ## ##Define our variables: DIRECT=~/Script ##Location of script&where to put results/temp files LOGFILE=/var/log/apache2/access.log ## Logfile to search for offenders TEMPLIST=xml_temp ## Temporary file name IP_LIST=ipstoban ## Name of results file FILTER1=xmlrpc ## What are we looking for? (Requests we want to ban) cd $DIRECT if [ ! -f $TEMPLIST ];then touch $TEMPLIST ##Create temp file fi cat $LOGFILE | grep $FILTER1 >> $DIRECT/$TEMPLIST ## Only interested in the IP's, so: sed -e 's/\([0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+\).*$/\1/' -e t -e d $DIRECT/$TEMPLIST | sort | uniq > $DIRECT/$IP_LIST rm $TEMPLIST ## Clean temp file echo "Done. Results located at $DIRECT/$IP_LIST" So I need help with the next part of the script, which should ban the IP's (incoming and perhaps outgoing too) from the resulting $IP_LIST file. I don't care if it utilizes UFW or IPTables directly, as long as it bans the IP's. I'd probably run it as a cron task. What I'm having trouble with is understanding how to use line of the result file as a seperate variable to do something like: ufw deny $IP1 $IP2 $IP3, ect Any ideas? Thanks.
