Fight BufferBloat by testing fq_codel by default in Arch

hi,
As suggested  by Dave Taht in here , there is a "chicken/egg" problem in the development of fq_codel as a replacement of pfifo_fast.
Basically it needs to be enabled as default in the wild to collect enough data for all kinds of scenarios.  Dave is trying to put a simple "debloat" script in Ubuntu, Arch and others.  So i decided to put the default enablement of his script in discussion.

  • Changing MS Office (test drive) from default word processor

    Sorry for sucking up so much topic space, but I spent the better part of an hour trying to figure out how to change my legitimate MS word 2004 to the default word processor from the test drive version that comes on the MBP. Everytime I click on a MS word file I get an error message because I deleted the test drive version that was set as the default to open the word documents--how do i change this???
    Any ideas? Seriously, I googled it and everything, it must be more simple than this!

    Hi seagonus,
    If you have removed the test drive from your computer, and now have the full version of Office installed, highlight the file, click on the More Info tab to the right. A box will open that will have a drop down that says "open with" . In the list you will see the option for Microsoft Word (default). If this doesn't work, then you haven't truly removed the test drive, and that could be the problem. If so run the uninstaller again that comes in your MS Office folder under "Additional Tools". Good luck!

  • Reg: Test Configuration with Default variant

    Hi Guru's
      I am new here.. Guide me to achieve this.
      I do created the Test script ,Test data and also the Test Configuration
      Whats my problem is  I do run the TC with external variant (File that i have mapped) .
       its works fine but Default variant is not triggering all other variant are triggering.
       What to do to run all the external variant including default variant . Guide me with steps.
    Thanks in advance
    Regards
    Anandh

    Hi Anandh,
    ECATTDEFAULT is a special variant which is not intended to be uploaded from external files.
    If you use the download option to prepare your external variant file as a sample, you will see that ECATTDEFAULT is deactivated by using * in front. It's only downloaded to the sample file for giving the scripts import parameter defaults as a reference.
    If you like use these default values for individual fields of other variants simply leave those fields blank in the other variants.
    To have your test executed with the whole record of ECATTDEFAULT simply copy the *ECATTDEFAULT line in your external data file and give it an other similar name, e.g. ECATTDEFAULT1.
    Kind regards

  • Larch-4 testing, can also 'livify' existing Arch installation

    I've uploaded a testing repository for larch-4 to:
    ftp://archie.dotsrc.org/projects/archie/larch/testing
    It has some added features which need testing - especially with USB, which is difficult for me to test because my computers are rather old and don't support USB boot.
    It should now be possible to adjust the session-saving behaviour without modifying the larch scripts - additional scripts (hooks / event-handlers, call them what you will ...) can be placed in a 'scripts' folder in the root directory of the boot device (using the profile mechanism) to adjust loading and saving of overlay files. Initial description (sorry, it's still rather sketchy) in the session-saving doc page.
    The home directory is now a separate sqf (not overlayed).
    Added options to mklarch to build a CD/USB-stick from an existing Arch installation. This can be done, for example, from a live CD (using the -x option) or even from the system itself while it is running (option -X). This could be rather dangerous - don't do it on your main installation. I've tried it out - without obvious damage - on a test installation, and it looked quite promising, but be careful.
    Added option -r to mklarch to ensure regeneration of base and system sqfs when 'reusing' an installation (with options -b, -x, -X).
    Changed the place where the live CD is built (default /home/larchroot) and the structure within this folder. The installation is now made directly to this location and the building is done in subfolder .larch, where the final iso also lands.
    To use it, just copy the larch-setup.sh script to an empty folder and run it (as before). Then you have the new mklarch set up and ready to go.
    Feedback welcome.

    Hi gradgrind, this tool is really what I'm looking for. I have 3 partitions: /dev/sda1 -> swap; /dev/sda2 -> reiserfs (partition where my system is installed); /dev/sda3 -> reiserfs (partition where I'm running mklarch script). I want to try larch but I have a few questions.
    1) To create a LiveCD from my current arch setup I only need to  run
    ./mklarch -X
    If you're running the system you want to save, yes. But from your description it sounds like you're doing something else. Do I understand correctly that you have some other system unrelated to sda2 on sda3 and you want to run mklarch from sda3? And what you want to livify is sda2? Then you need to do something like:
    # mount -o dev,exec /dev/sda2 /mnt/sda2
    # ./mklarch -x /mnt/sda2
    Note the small 'x'.
    spookykid wrote:2) Is it possible to add gensplash to larch?
    Sorry, I have no idea about gensplash. If it's supported by Arch then it should work with larch too, but it's not something in which I have any interest.
    spookykid wrote:3) For what I've read about larch I can have a system installed with 4 GB and that will fit on a 700 MB CD?
    I hope I didn't write that. You might need that much free space to build a 700MB CD, but a more accurate estimate of what fits would be about 2GB. If you want more you'll need correspondingly more free space and a DVD or a large USB-stick.
    spookykid wrote:4) Larch will only go for my /dev/sda2 partition (where i have my system) or will it add all available partitions to the live image?
    It just packs up what it finds at the mount point, so if you've got other stuff mounted within the system (I guess in your case you probably haven't) don't be surprised if it tries to pack that up too. I think (I hope!) it ignores stuff mounted within /mnt and /media, but I'd have to look at the code again to be sure. For people who have /home or /var or whatever on separate partitions it is necessary to mount these before running mklarch.
    If you use 'mklarch -X' (big 'X') to build a live CD from the currently running system, all the mounts should be ok anyway, but I think that in general building from a separate system, as you seem to want to do might be slightly safer.
    In any case, please back up anything important before running mklarch - just in case! It runs as root and could do all sorts of nasty things. I don't think it will, but don't blame me if it feeds your grandmother to the ravenous bugblatter beast of Traal

  • Can I test (junit) default case of switch-case statement ?

    Hi,
    I have a class which has switch-case statements and I am trying to junit test with 100% coverage. My switch-case workes based on enum values.
    say my enum values are 1, 2.
    switch(getEnumValues) {
    case 1:
    return "some value";
    case 2:
    return "some value";
    default:
    throw new UnsupportedOperationException("No such enum value supported.");
    I have test case to test the case 1 and 2 but I am not able to test default case. Can anyone please let me know how can I right a junit test case for default case.

    ~If I'm reading the OP correctly, they're 1 and 2, not ONE and TWO. That is, not values of a Java enum.
    If this is the case, then the easiest way to test the default case is to break the swtich out into a separate, package-accessible method that takes and arg and passes that onto the switch. (There may be variations on this, depending on how your code is structured.)
    However, in a similar vein to what the others are saying, if you already know that you'll only ever have 1 and 2 by the time you get to the switch (maybe because the value comes from an argument to the enclosing method, and you've already unit tested that it appropriately throws an IllegalArgumentException when other values are passed, then there's no need to test the default.
    Finally, though if it is ints 1 and 2, rather than a true enum, why not switch to an enum?

  • How to change default ringtone to a custom one for IPhone 5.

    I have gone into settings  through Sounds made the change, but it does not register as the default even though the ringtone chosen has the checkmark beside it.  Ringtone still lists the factory default under sounds & vibrations.
    I am able to customize ringtones for individual contacts.

  • URL links provided in emails (Windows Mail) stopped working. I get a popup message: "Windows cannot find...." asking me to make the URL is correct. I connect to Internet Explorer, but not Firefox, my default browser.

    I have already updated Firefox to latest version and reset the default mail program to Windows Mail. But Windows Mail now doesn't want to recognize Firefox. If I shift to Internet Explorer, I have no problem. I have no problem receiving or sending emails, just using links contained in them.
    This happened suddenly, two days ago, at the end of a day when linking had been possible, per usual.

    nothing that I could find would solve my problem, so I just gave up trying...
    then I had a group of Microsoft Updates badly interact with each other, causing me all kinds of stability problems involving SQL and printer drivers.
    To fix those issues, I backed out all updates within the prior two months, then [slowly and painfully!] reinstalled them -- when done in groups, you can tell how Microsoft corrects bad updates by noting which ones are not reinstalled.
    I also had to download and install every single MS SQL update available before everything that was broken worked again. Note that none of the updates had titles that suggested anything at all to do with web browsing (other than Internet Explorer) or Firefox.
    There was also at least one Firefox update shortly after my re-installation of Windows Updates.
    Funny thing happened along that path: as of today (version 32.0.1) has none of the problems I reported, but I cannot say for certain which change fixed them: I was far more concerned fixing SQL and printer issues to even test Firefox for default file association settings.
    Sorry that I cannot be more useful, other than the general suggestions to:
    (1) keep your system fully updated with all patches
    (2) keep your anti-virus, anti-malware, and anti-spybot software current as well
    (3) keep any program that uses HTML and other browser protocols also up to date
    (4) take regular snapshots of your registry, and create a system restore point before every system and software update, so you can more easily back out problems
    (5) keep the installation package(s) for prior version(s) of software (and Windows Update files) at least until you verify an update hasn't broken anything.
    Hope that helps.

  • How to set default locale in JDK1.3.0 to US?

    Hi, everyone!
    I found the default locale in JDK 1.3.0 is not set to US when I converted our JDK from 1.2 to 1.3.0. So I have to change code by passing Locale.US.
    The output from below test code is:
    default=��100.00
    US=$100.00
    import java.util.Locale;
    import java.text.*;
    public class TestCurrency
    public static void main(String[] args)
    int amount = 100;
    //default
    NumberFormat moneyWriter = NumberFormat.getCurrencyInstance();
    System.out.println ("default=" + moneyWriter.format(amount) );
    //US
    moneyWriter = NumberFormat.getCurrencyInstance(Locale.US);
    System.out.println ("US=" + moneyWriter.format(amount) );
    Can anyone tell me how to set default locale in JDK 1.3.0 to US?
    Thanks!

    You have to set something on your computer (outside Java) to tell it that you are in the US. You didn't say, but I'm going to guess that you are using Windows; if that's so, then try Regional Options in Control Panel.

  • Office Test Drive is a pain

    Bought new MacBook - great!
    FireWire all my work and applications from iMac - great!
    Start using Office (purchased 2yrs ago) and Test Drive wants me to buy again - not so great!
    Removed Test Drive using "Remove" application residing in Test Drive folder and change all my files in "Get info" to open using my original version of Office but get error 10660. Now all my existing and new files will not open and come up with error 10660. The only way to open them is to change "open with" in "Get info" on every single file
    (this is 100s) even although I changed "open with" to "chnage all". When I go to the "open with" menu I can still see the old version of Test Drive as default even although I used the remove application - pain in the **
    This is another case of Microsoft trying to take over the world. Why has Apple allowed this?
    Any suggestions would be very welcome.
    thx

    I didn't install Office just used the FireWire cable to transfer. Surely this is the whole idea that you don't need to install your exisiting software again! It was a couple of days before I realised that Test Drive had taken control of my computer.
    Thanks for your comments anyway but I still think Apple should re-think pre-loading Test Drive. It has and will cost me time to put it right. Who do you think I should send the bill to?
    Ok I've stopped moaning now!

  • Status updates history period default

    Hi
    Is there any way to change the default status updates history date range from 3 months please?  Currently as the status approver for a major change program I'm getting several hundred tasks to approve every day across multiple project plans; the problem
    is that when I go in to clear down to run my weekly reports it lists every task submission for the last 3 months.  The thing is, IE can take several minutes before it displays the page in full as it chews through all of the data which is annoying
    to say the least.
    I'd quite like it to show only the last 3 weeks, not the last 3 months.
    Does anyone have any suggestions please?
    Thanks.

    Hi,
    As far as I tested, changing the default 3 months range from the date range feature will unfortunaltely not be kept in your IE cache next time you'll navigate to the status update history page. Thus you'll have to set it again every time you access
    the page.
    I guess this 3 months default value might be changed programmabily but I can't help on this.
    Hope this helps,

  • Bought and set new ringtone, but won't ring with anything except default

    I've got an iPhone 3GS (only a few days old) and downloaded a ringtone from iTunes direct to the 'phone.
    I set it as my main ringtone through Settings > Sounds > Ringtone. All seemed simple enough. Except when I then tested it, the default tone still rang. I tried changing the ringtone to one of the other iPhone core ones that are already on the 'phone, but found I couldn't change to any of these either...
    I've synced the 'phone, I can select the ringtones on my 'phone and play them to test them, but I can't change my ringtone - at all. This is driving me insane.
    Anybody have any ideas?

    OK, I'm officially an idiot. I've been testing it by calling from my wife's 'phone. I've now just checked her contact record and at some point in the dim and distant past I've set a specific ringtone for her contact...
    By resetting that to the default it's now using the correct ringtone... D'oh!
    Apologies for wasting your time, and thanks for trying to help this dimwit... :S

  • While connecting to the default instance from out side of the server it's reaches to Named instance ?i

    Hi All,
    We have two named instance in "test" server. the names like test\a & test\b... The tcp\ip for test\a is dynamic and for test\b is default port 1433... Now customer requested to install the default instance...we had an issue with installation
    that is the default port number is in use so, the default installation failed and then i changed the settings in registry to use the dynamic port for default instance and then i manually start the sql servers...seems all are good...but when i connecting this
    default instance from out side of the box through SSMS it's pointing to the named instance which one having the default port number(test\b).
    We can change the port number for test\b and assign that port to default instance...but the applications which are connecting to the test\b those are using the default port number...so, we don't want to disturb the connectivity...
    is there any way to fix this issue with out changing the port number for test\b ?
    it is urgent...we have to fix this issue ASAP.. 
    Thanks in Advance,
    rup

    Hi rup,
    Glad to hear the issue is resolved.
    As your post, if SQL Server is configured to use dynamic port,
    it is difficult for application connectivity because the port number selected changes every time that the Database Engine is started.
    From your description, you have changed the dynamic port number to static port number. To avoid a common pitfall, please also ensure that 
    you have deleted the entry (0 or some random port) for dynamic port in SQL Server Configuration Manager. For more details, please review this
    blog.
