How to get a Sun Ray to load a firmware from elsewhere

- by vdiozguy

I run a Sun Ray/VDI demo environment internally within the company - and because it's not a public service, I need to tell my Sun Rays to connect to it directly so that I don't get redirected to the corporate servers. To get any new Sun Ray to connect to *my* setup I usually pull out my laptop so that the Sun Ray can load the new version of the F/W along with the permission to pull up the management GUI via STOP-S.But there is a better way if you have another Sun Ray server handy:1) allow your Sun Ray to connect to the default corporate server2) log in to a "regular" session, that is a Solaris or Linux desktop on the Sun Ray server itself3) in a terminal, utswitch to your server (/opt/SUNWut/bin/utswitch -h myserver)4) again, login to a regular session there5) in a terminal, issue "/opt/SUNWut/lib/utload -S myserver -w"6) Watch your firmware load and wait7) the Sun Ray will reboot and connect to the first server again. Repeat steps 2-48) issue "/opt/SUNWut/lib/utload -S myserver -f SunRay.enableGUI"9) Press STOP-S and be merryNOTE: I'm sure there is even yet a better way - this is totally unsupported, most likely a figment of my imagination. In any case, this post will self-destruct in BOOM.

Lumia 920 or iPhone5, which is it gonna be?

- by Sahil Malik

SharePoint 2010 Training: more information Deciding on a new phone is so difficult. I currently use an iPhone4, and I am itching to upgrade to either iPhone5 or Lumia 920. The decision is difficult because a lot of my work depends on my communication device, and whatever I pick, I will be stuck with for 2 years. Here is how I see the two stacking up. iPhone 5 of course based on rumors so far. I didn’t even consider Android here because I don’t like Android as an OS. It’s too insecure, privacy intrusive, and frankly unreliable. I cannot bet my work on Android, sorry not gonna happen. Read full article ....

My company's management wants to deduct from the salary of under performing employees. How can I convince them not to?

- by Sparky

My company's management wants to deduct from the salary of under performing employees. I'm a member of the Core Strategy committee and they want my opinion also. I believe that the throughput from an employee depends on a lot of things such as the particular work assigned to them, other members of his/her team, other reasons etc. Such penalizations will be demoralizing to the people. How can I convince my management not to do so?

when to choose ruby on rails over java [closed]

- by Dany Y

I have been working with Java EE for 6 years, and I have mostly used it even for simple applications like data-entry to database). I heard Ruby on Rails is superior to Java in this domain. What are the actual advantages of Ruby. and should I switch ? P.S : I know this is a subjective question, and the most probable answer is "depends on what you'll use it for", but this is exactly what I want to know when to use what. Thank you

Breaking up a large PHP object used to abstract the database. Best practices?

- by John Kershaw

Two years ago it was thought a single object with functions such as $database->get_user_from_id($ID) would be a good idea. The functions return objects (not arrays), and the front-end code never worries about the database. This was great, until we started growing the database. There's now 30+ tables, and around 150 functions in the database object. It's getting impractical and unmanageable and I'm going to be breaking it up. What is a good solution to this problem? The project is large, so there's a limit to the extent I can change things. My current plan is to extend the current object for each table, then have the database object contain these. So, the above example would turn into (assume "user" is a table) $database->user->get_user_from_id($ID). Instead of one large file, we would have a file for every table.

Is encoding needed in this decryption?

- by Lijo

I have a Encryption – Decryption scenario as shown below. //[Clear text ID string as input] -- [(ASCII GetByte) + Encoding] -- [Encrption as byte array] -- [Database column is in VarBinary] -- [Pass byte[] as VarBinary parameter to SP for comparison] //[ID stored as VarBinary in Database] -- [Read as byte array] -- [(Decrypt as byte array) + Encoding + (ASCII Get String)] -- Show as string in the UI My question is in the decryption scenario. After decryption I get a byte array. I am doing an encoding (IBM037) after that. Is it correct? Is there something wrong in the flow shown above? private static byte[] GetEncryptedID(string id) { Interface_Request input = new Interface_Request(); input.RequestText = Encodeto64(id); input.RequestType = Encryption; ProgramInterface inputRequest = new ProgramInterface(); inputRequest.Test_Trial_Request = input; using (KTestService operation = new KTestService()) { return ((operation.KTrialOperation(inputRequest)).Test_Trial_Response.ResponseText); } } private static string GetDecryptedID(byte[] id) { Interface_Request input = new Interface_Request(); input.RequestText = id; input.RequestType = Decryption; ProgramInterface request = new ProgramInterface(); request.Test_Trial_Request = input; using (KTestService operationD = new KTestService()) { ProgramInterface1 response = operationD.KI014Operation(request); byte[] decryptedValue = response.ICSF_AES_Response.ResponseText; Encoding sourceByteFormat = Encoding.GetEncoding("IBM037"); Encoding destinationByteFormat = Encoding.ASCII; //Convert from one byte format to other (IBM to ASCII) byte[] ibmEncodedBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat,decryptedValue); return System.Text.ASCIIEncoding.ASCII.GetString(ibmEncodedBytes); } } private static byte[] EncodeTo64(string toEncode) { byte[] dataInBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode); Encoding destinationByteFormat = Encoding.GetEncoding("IBM037"); Encoding sourceByteFormat = Encoding.ASCII; //Convert from one byte format to other (ASCII to IBM) byte[] asciiBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat, dataInBytes); return asciiBytes; }

Are CK Metrics still considered useful? Is there an open source tool to help?

- by DeveloperDon

Chidamber & Kemerer proposed several metrics for object oriented code. Among them, depth of inheritance tree, weighted number of methods, number of member functions, number of children, and coupling between objects. Using a base of code, they tried to correlated these metrics to the defect density and maintenance effort using covariant analysis. Are these metrics actionable in projects? Perhaps they can guide refactoring. For example weighted number of methods might show which God classes needed to be broken into more cohesive classes that address a single concern. Is there approach superseded by a better method, and is there a tool that can identify problem code, particularly in moderately large project being handed off to a new developer or team?

What are some good examples of using pass by name?

- by Paul

When I write programs I using pass by value or pass by reference always seem to be logical methods. When learning about different programming languages I came across pass by name. Pass by name is a parameter passing method that waits to evaluate the parameter value until it is used. See Stack Overflow pass by name question for more information on the method. What I would like to know is: what are some good examples and/or reasons to use pass by name and should it be re-introduced into some more modern languages.

Is Oberon really "a better Pascal"?

- by Maksee

Reading Niklaus Wirth, one can notice that despite some popularity of Pascal, he is not glad that Oberon (as a "polished" successor of Pascal and Modula) didn't get much popularity. I never did anything in Oberon, but reading the page Oberon For Pascal Developers I really did not like many of the changes as a Delphi/pascal developer, for example forcing the reserved words to be always uppercase making the language case-sensitive getting rid of enumeration types What do you think about Oberon, is it really "a better Pascal" from your point of view?

Bluetooth fix for Ubuntu 12.04, lenovo G580

- by Sam Abraham

Bluetooth not working, it shows turned on but manager indicated Bluetooth disabled. Uninstalled default manager and installed Blueman. The same with Blueman, clicking on connect to devices gets response 'adapters not found'. I've found many more people with the same problem. The fixes found in the archive don't work for me. I've tried a couple of things from the forum. I'm not familiar with computer hardware or software but have been using Ubuntu cause it saves me money, it's fairly easy to use and it does not tax my mid-range lap. Any help will be appreciated.

12.04 - why does the network icon dissapear every time my machine is turned off

- by Howard Walker

After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

How to check if a cdrom is in the tray remotely (via ssh)?

- by adempewolff

I have a server running Ubuntu 10.04 (it's on the other side of the world and I haven't built up the wherewithal to upgrade it remotely yet) and I have been told that there is a CD in one of it's two CD drives. I want to rip an image of the cd and then download it to my local computer (I don't need help with either of these steps). However, I cannot seem to confirm whether or not there actually is a CD in the drive as I was told. It did not automatically mount anywhere (which I'm thinking might just be a result of it being a headless server not running X, nautilus, or any of the other nice user friendly things). There are two CD drives connected via SCSI: austin@austinvpn:/proc/scsi$ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: WDC WD400EB-75CP Rev: 06.0 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: Lite-On Model: LTN486S 48x Max Rev: YDS6 Type: CD-ROM ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: SAMSUNG Model: CD-R/RW SW-248F Rev: R602 Type: CD-ROM ANSI SCSI revision: 05 However when I try mounting either of these devices (and every other device that could possibly be the cd-drive), it says no medium found: austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd1 /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd0 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom1 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrw /cdrom mount: no medium found on /dev/sr1 Here are the contents of my /dev folder: austin@austinvpn:/proc/scsi$ ls /dev agpgart loop6 ram6 tty10 tty38 tty8 austinvpn loop7 ram7 tty11 tty39 tty9 block lp0 ram8 tty12 tty4 ttyS0 bsg mapper ram9 tty13 tty40 ttyS1 btrfs-control mcelog random tty14 tty41 ttyS2 bus mem rfkill tty15 tty42 ttyS3 cdrom net root tty16 tty43 urandom cdrom1 network_latency rtc tty17 tty44 usbmon0 cdrw network_throughput rtc0 tty18 tty45 usbmon1 char null scd0 tty19 tty46 usbmon2 console oldmem scd1 tty2 tty47 usbmon3 core parport0 sda tty20 tty48 usbmon4 cpu_dma_latency pktcdvd sda1 tty21 tty49 vcs disk port sda2 tty22 tty5 vcs1 dri ppp sda5 tty23 tty50 vcs2 ecryptfs psaux sg0 tty24 tty51 vcs3 fb0 ptmx sg1 tty25 tty52 vcs4 fd pts sg2 tty26 tty53 vcs5 full ram0 shm tty27 tty54 vcs6 fuse ram1 snapshot tty28 tty55 vcs7 hpet ram10 snd tty29 tty56 vcsa input ram11 sndstat tty3 tty57 vcsa1 kmsg ram12 sr0 tty30 tty58 vcsa2 log ram13 sr1 tty31 tty59 vcsa3 loop0 ram14 stderr tty32 tty6 vcsa4 loop1 ram15 stdin tty33 tty60 vcsa5 loop2 ram2 stdout tty34 tty61 vcsa6 loop3 ram3 tty tty35 tty62 vcsa7 loop4 ram4 tty0 tty36 tty63 vga_arbiter loop5 ram5 tty1 tty37 tty7 zero And here is my fstab file: austin@austinvpn:/proc/scsi$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

New install preserving home directory

- by john francis lee

I have 32bit 11.10 installed on an LVM disk taking up all 500gb, and I would like to install 64bit 12.04 on top ... preserving the data in my home directory. I used to do that pre-LVM by just not formatting the partition mounted as /home, installing over / and /usr and formatting /tmp ... but now I don't recognize the partition table. I've never had much luck with 'upograde' and so I just install afresh when I want t new version. Surely I can do what I want, can't I?

.pam_environment in kerberized nfs4 home directory

- by Paul Stoever

How can I get pam_env to read the user's .pam_environment file, if the user's file is located in a kerberized NFS4 mount? The file and directory permissions for the .pam_environment file are set in a way, that allows the local root to read the file. Reading .pam_environment only fails on the first login. Subsequent logins successfully read the file. The client uses Ubuntu 12.04 Desktop, NFS/Kerberos server is 12.04 Server. The Kerberos/NFS4 stuff works with exception of this. From /var/log/auth for first login: ... lightdm: pam_krb5(lightdm:auth): user USERNAME authenticated as USERNAME@REALM lightdm: pam_unix(lightdm:session): session closed for user lightdm lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_unix(lightdm:session): session opened for user USERNAME by (uid=0) ...

Network does not connect at boot

- by Daniel Svozil

I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel
