• How can I make the function keys the default on a Logitech K760 Bluetooh keyboard?

  - by Chas. Owens

  I had hoped that solaar would help, but it seems to only work for the Logitech wireless devices that use Logitech's proprietary scheme. I have Bluetooth keyboard (K760). I know it can be told to use the function keys (rather than the media keys) by default because I can do it on under OS X with software from Logitech. Just remapping the keys won't work as F1, F2, and F3 are special in that they switch which Bluetooth device I connect to and the keys are not sent to the OS.

• Can I install Natty alongside Maverick and retain my encrypted /home partition?

  - by Jon

  This is my partitioning scheme: 10GB partition empty -- will be installing Natty here 10GB partition containing Maverick 2GB swap partition 300GB encrypted /home partition I've had few problems in the past with having two ubuntu installs on two separate partitions, giving /home it's own partition, but I'm a little concerned since I'm now using an encrypted /home partition. Install won't try to wipe my /home if I click " encrypt home directory," will it?

• Can you be a manager and a programmer at the same time?

  - by Pierre 303

  Managing other programmers while you are yourself a part of the programming work force. It's a very common scheme, at least in the companies I worked for. Can you be a good programmer or a good manager if you do both at the same time? I'm questioning the effectiveness of an individual that has to be in two very different roles, requiring very different skills, environment, concentration, organization, etc.

• SQL Server 2008 R2 Reporting Services: A generic error occurred in GDI+

  While building some maps today in SQL Server 2008 R2 Reporting Services, I kept coming up with an error that said: A generic error occurred in GDI+ I was struggling to think what I'd done wrong. After much nashing of teeth and removal of hair, I finally worked out what the error was.

• How were some language communities (eg, Ruby and Python) able to prevent fragmentation while others (eg, Lisp or ML) were not?

  - by chrisaycock

  The term "Lisp" (or "Lisp-like") is an umbrella for lots of different languages, such as Common Lisp, Scheme, and Arc. There is similar fragmentation is other language communities, like in ML. However, Ruby and Python have both managed to avoid this fate, where innovation occurred more on the implementation (like PyPy or YARV) instead of making changes to the language itself. Did the Ruby and Python communities do something special to prevent language fragmentation?

• Top down space game control problem

  - by Phil

  As the title suggests I'm developing a top down space game. I'm not looking to use newtonian physics with the player controlled ship. I'm trying to achieve a control scheme somewhat similar to that of FlatSpace 2 (awesome game). I can't figure out how to achieve this feeling with keyboard controls as opposed to mouse controls though. Any suggestions? I'm using Unity3d and C# or javaScript (unityScript or whatever is the correct term) works fine if you want to drop some code examples. Edit: Of course I should describe FlatSpace 2's control scheme, sorry. You hold the mouse button down and move the mouse in the direction you want the ship to move in. But it's not the controls I don't know how to do but rather the feeling of a mix of driving a car and flying an aircraft. It's really well made. Youtube link: FlatSpace2 on iPhone I'm not developing an iPhone game but the video shows the principle of the movement style. Edit 2 As there seems to be a slight interest, I'll post the version of the code I've used to continue. It works good enough. Sometimes good enough is sufficient! using UnityEngine; using System.Collections; public class ShipMovement : MonoBehaviour { public float directionModifier; float shipRotationAngle; public float shipRotationSpeed = 0; public double thrustModifier; public double accelerationModifier; public double shipBaseAcceleration = 0; public Vector2 directionVector; public Vector2 accelerationVector = new Vector2(0,0); public Vector2 frictionVector = new Vector2(0,0); public int shipFriction = 0; public Vector2 shipSpeedVector; public Vector2 shipPositionVector; public Vector2 speedCap = new Vector2(0,0); void Update() { directionModifier = -Input.GetAxis("Horizontal"); shipRotationAngle += ( shipRotationSpeed * directionModifier ) * Time.deltaTime; thrustModifier = Input.GetAxis("Vertical"); accelerationModifier = ( ( shipBaseAcceleration * thrustModifier ) ) * Time.deltaTime; directionVector = new Vector2( Mathf.Cos(shipRotationAngle ), Mathf.Sin(shipRotationAngle) ); //accelerationVector = Vector2(directionVector.x * System.Convert.ToDouble(accelerationModifier), directionVector.y * System.Convert.ToDouble(accelerationModifier)); accelerationVector.x = directionVector.x * (float)accelerationModifier; accelerationVector.y = directionVector.y * (float)accelerationModifier; // Set friction based on how "floaty" controls you want shipSpeedVector.x *= 0.9f; //Use a variable here shipSpeedVector.y *= 0.9f; //<-- as well shipSpeedVector += accelerationVector; shipPositionVector += shipSpeedVector; gameObject.transform.position = new Vector3(shipPositionVector.x, 0, shipPositionVector.y); } }

• How to separate production and test assets during development?

  - by bcsanches

  Hi Folks, this is like a complement for Assets Management, database or versioning system?. I am wondering about how to separate development, specially programmers assets from production assets? For example, if we keep all the assets on the same repository, how do you keep with programmers assets and final game assets? Do you keep a separate directory for each of those, allowing duplicates? Or do you use some fancy scheme for striping out the "development" and "test" assets from final build?

• Advantages to Multiple Methods over Switch

  - by tandu

  I received a code review from a senior developer today asking "By the way, what is your objection to dispatching functions by way of a switch statement?" I have read in many places about how pumping an argument through switch to call methods is bad OOP, not as extensible, etc. However, I can't really come up with a definitive answer for him. I would like to settle this for myself once and for all. Here are our competing code suggestions (php used as an example, but can apply more universally): class Switch { public function go($arg) { switch ($arg) { case "one": echo "one\n"; break; case "two": echo "two\n"; break; case "three": echo "three\n"; break; default: throw new Exception("Unknown call: $arg"); break; } } } class Oop { public function go_one() { echo "one\n"; } public function go_two() { echo "two\n"; } public function go_three() { echo "three\n"; } public function __call($_, $__) { throw new Exception("Unknown call $_ with arguments: " . print_r($__, true)); } } Part of his argument was "It (switch method) has a much cleaner way of handling default cases than what you have in the generic __call() magic method." I disagree about the cleanliness and in fact prefer call, but I would like to hear what others have to say. Arguments I can come up with in support of Oop scheme: A bit cleaner in terms of the code you have to write (less, easier to read, less keywords to consider) Not all actions delegated to a single method. Not much difference in execution here, but at least the text is more compartmentalized. In the same vein, another method can be added anywhere in the class instead of a specific spot. Methods are namespaced, which is nice. Does not apply here, but consider a case where Switch::go() operated on a member rather than a parameter. You would have to change the member first, then call the method. For Oop you can call the methods independently at any time. Arguments I can come up with in support of Switch scheme: For the sake of argument, cleaner method of dealing with a default (unknown) request Seems less magical, which might make unfamiliar developers feel more comfortable Anyone have anything to add for either side? I'd like to have a good answer for him.

• Botnet Malware Sleeps Eight Months Activation, Child Concerns

  Daily Safety Check experts used a computer forensic analysis of a significant botnet that consisted of Carberp and SpyEye malware to come up with the details for their report. The analysis found that the botnet profiled the behavior of the slave computers it infected, similar to surveillance techniques used by law enforcement agencies, for an average of eight months. During the eight months, the botnet analyzed each computer's users and assigned ratings to certain activities to form a complete profile for each. Doing so allowed those behind the scheme to determine which were the most favora...

• Weird Ubuntu Desktop Boot Partition On External Hard Drive

  - by Magnitus

  I have a Thinkpad with Windows 7. Last time I installed an Ubuntu/Windows dual boot, Windows was never same after and regularly got corrupted so this time, I installed Ubuntu on a separate external hard drive. I took a 500 GB external hard drive and used Windows to shrink the partition on it to 400 GB, freeing 100 GB to install Ubuntu. Then I modified the booting priority of my computer to boot from the external hard drive if present. Then, I installed Ubuntu desktop on the external hard drive using a DVD, picked the most simplistic partitioning scheme I could get away with (didn't go auto as it didn't include the external hard drive as a choice) and voilà. Fast forward some time and I'm trying to refresh my understanding of Linux partitions to install a bunch of servers, so I'm looking at the current partitioning scheme on my external hard drive and find the boot partition puzzling... sda is my integrated hard drive with Windows 7. sdb is my Ubuntu desktop external hard drive. Running parted on sdb, I get this: (parted) print Model: WD My Passport 0740 (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 393GB 393GB primary ntfs boot 2 393GB 500GB 107GB extended 5 393GB 425GB 32.8GB logical linux-swap(v1) 6 425GB 500GB 74.6GB logical ext4 At this point, I'm wondering why the ntfs partition is flagged as "boot" and not my ext4 partition which is the partition that contains / (and by extension, /boot since it's not on its own separate partition). Looking at mtab only confirms what I already know: eric@eric-ThinkPad-W530:~$ sudo cat /etc/mtab /dev/sdb6 / ext4 rw,errors=remount-ro 0 0 proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 none /sys/fs/cgroup tmpfs rw 0 0 none /sys/fs/fuse/connections fusectl rw 0 0 none /sys/kernel/debug debugfs rw 0 0 none /sys/kernel/security securityfs rw 0 0 udev /dev devtmpfs rw,mode=0755 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0 tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0 none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0 none /run/shm tmpfs rw,nosuid,nodev 0 0 none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0 none /sys/fs/pstore pstore rw 0 0 systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=eric 0 0 /dev/sdb1 /media/eric/My\040Passport fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0 My lack of understanding concerning this is not vital to anything (this is only my development desktop partition), but somehow annoys me. Any insight that could shed some light on this would be welcome.

• Ubuntu 10.04 preseed unattended install results in faulty partition table

  - by joschi

  I'm currently trying to set up an unattended installation of Ubuntu 10.04 (Lucid Lynx) through preseeding. But whenever I try to create a custom partition scheme, the Debian installer (which Ubuntu is using) produces a faulty partition table. I've taken the partition scheme described in the example preseed file: d-i partman-auto/expert_recipe string \ boot-root :: \ 40 50 100 ext3 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ /boot } \ . \ 500 10000 1000000000 ext3 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ method{ swap } format{ } \ . Unfortunately it also produces an incorrect partition table on the disk. The installation process itself is working and the installed system eventually boots and is working, as far as I can tell. But fdisk and cfdisk are still complaining: # fdisk -l /dev/sda Disk /dev/sda: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 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: 0x000a1cdd Device Boot Start End Blocks Id System /dev/sda1 * 1 5 37888 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 5 2089 16736257 5 Extended /dev/sda5 5 2013 16121856 83 Linux /dev/sda6 2013 2089 613376 82 Linux swap / Solaris cfdisk even refuses to start at all: # cfdisk /dev/sda FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder parted on the other hand does not complain about the cylinder boundary of /dev/sda1: # parted /dev/sda p Model: VMware Virtual disk (scsi) Disk /dev/sda: 17.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 39.8MB 38.8MB primary ext4 boot 2 40.9MB 17.2GB 17.1GB extended 5 40.9MB 16.5GB 16.5GB logical ext4 6 16.6GB 17.2GB 628MB logical linux-swap(v1) Since the installed system is working, it shouldn't be a big problem but I'm afraid that this will mean trouble in the future.

• Switch Windows 8 from a hybrid MBR/GPT => GPT only on Macbook Pro Retina

  - by Sid

  I used DiskUtility+Bootcamp Wizard to setup my hard drive for Windows 8 (final MSDN). Somewhere in that process, the Apple tools turned my GPT disk into a hybrid MBR/GPT. All my 4 primary MBR partitions are used up, so when I try turning on Bitlocker in Windows 8, it complains about not finding a System drive. I know on Windows 8 the Bitlocker setup tries to create the 200(?)MB system partition if it's missing. However with all 4 partitions filled I suspect it can't create system drive = it can't find it = throws back an error like "BitLocker Setup could not find a target system drive. You may need to manually prepare your drive for BitLocker". I've already tried disabling hibernation, swap file etc. Now I'm thinking that if I were to get rid of the MBR scheme altogether, perhaps I can be alright within the GPT world without MBR's 4 primary partitions limit. So, how can I get rid of the MBR tables on the hybrid scheme in a manner that still leaves Mac OS and Windows 8 in working conditions? Details: Hardware is the MacbookPro Retina. Primary MBR partitions are consumed as follows: EFI partition HFS+ partition (=encrypted, therefore ="Apple_CoreStorage") HFS+ partition (Recovery partition, contains unencrypted Mac bootloader) NTFS partition (Windows8 all-in-one partition) diskutil list output sid-mbpr:~ sid$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_CoreStorage 160.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data Win8 90.1 GB disk0s4 GPT vs MBR addresses sid-mbpr:~ sid$ sudo gptsync /dev/rdisk0 Password: Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 312909639 Unknown 3 312909640 314179175 Mac OS X Boot 4 314179584 490233855 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 312909639 ac Apple RAID 3 312909640 314179175 ab Mac OS X Boot 4 * 314179584 490233855 07 NTFS/HPFS Status: GPT partition of type 'Unknown' found, will not touch this disk.** **: Ignore this message, the gptsync tool is old and doesn't understand the UUID for "Apple_CoreStorage" / FileVault2 partitions.

• Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx)

  - by Finglish

  Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx) I am attempting to use nginx to serve private files from django. For X-Access-Redirect settings I followed the following guide http://www.chicagodjango.com/blog/permission-based-file-serving/ Here is my site config file (/etc/nginx/site-available/sitename): server { listen 80; listen 443 default_server ssl; server_name localhost; client_max_body_size 50M; ssl_certificate /home/user/site.crt; ssl_certificate_key /home/user/site.key; access_log /home/user/nginx/access.log; error_log /home/user/nginx/error.log; location / { access_log /home/user/gunicorn/access.log; error_log /home/user/gunicorn/error.log; alias /path_to/app; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_pass http://127.0.0.1:8000; proxy_connect_timeout 100s; proxy_send_timeout 100s; proxy_read_timeout 100s; } location /protected/ { internal; alias /home/user/protected; } } I then tried using the following in my django view to test the download: response = HttpResponse() response['Content-Type'] = "application/zip" response['X-Accel-Redirect'] = '/protected/test.zip' return response but instead of the file download I get: 403 Forbidden nginx/1.1.19 Please note: I have removed all the personal data from the the config file, so if there are any obvious mistakes not related to my error that is probably why.

• Configuring https access on HP A5120 Switch

  - by GerryEgan

  I am trying to configure HTTPS management on a HP a5120 switch running Version 5.20.99, Release 2215 and not having much luck. I have followed the manual by creating an SSL policy first and then enabling the HTTPS server with the SSL policy: ssl server-policy sslpol ip https ssl-server-policy sslpol ip https enable When I try and log onto the switch with Google Chrome I get the following error: Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. When I look this up I have found references to errors due to TLS being used in SSL. I can find no way to specify the SSL version in the server policy. The manual has a configuration example that uses MSCEP to retrieve a certificate but in Windows 2008 R2 that feature is only available in Enterprise and Datacentre editions which I don't have. I have SSH configured and it is using a locally generated certificate so I'm not sure if I can use that but I'd like to if possible. Has anybody been able to setup HTTPS management on HP A series switches without MSCEP? Any and all help appreciated! here is a copy of my config with the interfaces removed: version 5.20.99, Release 2215 # sysname MYSYSNAME # irf domain 10 irf mac-address persistent timer irf auto-update enable undo irf link-delay # domain default enable system # telnet server enable # vlan 1 # vlan 100 description Management # radius scheme system primary authentication 127.0.0.1 1645 primary accounting 127.0.0.1 1646 user-name-format without-domain # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher authorization-attribute level 3 service-type ssh telnet terminal service-type web # stp enable # ssl server-policy sslpol pki-domain MYDOMAIN # interface NULL0 # interface Vlan-interface199 ip address 192.168.199.140 255.255.255.0 # interface GigabitEthernet1/0/1 poe enable stp edged-port enable # interface Ten-GigabitEthernet2/1/2 # dhcp-snooping # ntp-service unicast-server 192.168.1.71 # ssh server enable # ip https ssl-server-policy sslpol ip https enable # load xml-configuration # user-interface aux 0 1 user-interface vty 0 15 authentication-mode scheme

• Is my webserver being abused for banking fraud?

  - by koffie

  Since a few weeks i'm getting a lot of 403 errors from apache in my log files that seem to be related to a bank frauding scheme.

I suspect not, because it's giving 403 to all requests. But any extra checks that I can do to ensure that my server is not being abused are welcome. I'm also curious on how the "bad guys" expected my server to behave. I.e. are they just expecting my server to act as a proxy to hide the ip of the fake site, or are they expecting that my server will actually serve the fake banking website? Is the ip 1.2.3.4 more likely to be the ip of a victim or the ip of a bad guy. I suspect a bad guy, because it's quite unlikely that a real person would visit 4 bank sites in a second. If it's from a bad guy I'm very curious at what he is trying to do.

My nginx .conf file looks like this: server { # ... location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 60; proxy_pass http://localhost:8000/; } } The idea is to allow requests of 20M for two locations: /admin/path/to/upload?param=value /installer/other/path/to/upload?param=value I've tried to add location directives at the same level than the one I've pasted here (getting 404 errors) and also tried to add them inside the location / directive (getting 413 Entity Too Large errors). My location directives look like these in their simplest form: location /admin/path/to/upload/ { client_max_body_size 20M; } location /installer/other/path/to/upload/ { client_max_body_size 20M; } But they don't work (actually I tested lots of combinations and I'm desperate thinking about this. Please, help If you can: What settings do I need to set to make this work? Thank you so much!

• Nginx and Gunicorn hanging on GET requests

  - by whatWhat

  I'm using Nginx + Gunicorn which is serving my Django project. All GET requests hang for ~1 min. The content seems to be available immediately as I can see it in the Browser inspector but the browser itself looks like it's still waiting for more data. Heres my Ngnix config #allow for up to 3 connections per second. limit_req_zone $binary_remote_addr zone=one:10m rate=3r/s; server { listen 80; server_name example.com; root /var/www/example.com/example/; # serve directly - analogous for static/staticfiles location /media/ { # this changes depending on your python version root /home/example/; } location /static/ { # if asset versioning is used if ($query_string) { expires max; } root /var/www/example.com; } location / { #Allow for a burst of 50. limit_req zone=one burst=50 nodelay; proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 10; proxy_pass http://localhost:8001/; } # what to serve if upstream is not available or crashes error_page 500 502 503 504 /media/50x.html; } My Gunicorn Config: bind = "127.0.0.1:8001" workers = 3 worker_class = "gevent" Is there anything obvious that would be causing the requests to stay open for so long?
