• Canonical détaille ses plans pour le support de l'UEFI Secure Boot, GRUB 2 ne sera plus utilisé par défaut sur les futures versions d'Ubuntu

  Canonical détaille ses plans pour le support de l'UEFI Secure Boot GRUB 2 ne sera plus utilisé par défaut sur les futures versions d'Ubuntu Pour son futur système d'exploitation Windows 8, Microsoft a opté pour l'utilisation de l'UEFI ( Unified Extensible Firmware Interface) en remplacement du BIOS. Les constructeurs désireux de proposer des dispositifs sous l'OS seront donc obligés de passer à l'UEFI, avec une activation par défaut de la fonction Secure Boot. Cette fonctionnalité de sécurité offrira au système d'exploitation un processus de démarrage signé et mesuré, qui aide à protéger le PC en détectant les logiciels malveillants au démarrage, et en empêchant le chargement de c...

• Is the using of dirname(__FILE__) a good practice?

  - by webose

  looking at the code of Joomla I see that in the first line of the index, it defines the base path of installation with the dirname(FILE) is this a font of possible risk for the site, I mean if a non controlled error message show the internal path of the Joomla directory, because of, for example a failed include, can it be used to perform some kind of attack to the site ? If yes, is it convenient to use this function ? Any idea is welcome. Thanks

• Windows 8: Paradigm Shift

  You've probably heard a lot about the loss of the Start button in Windows 8. While it isn't completely lost - you can still get to it via a convoluted path - its disappearance is merely a sign of the rethinking that went into the operating system's creation. Window 8's designers made certain assumptions while building the new system: Users will interact with the operating system predominantly through a touch interface. Users will do their computing on mobile devices, and may in fact use several different devices for the same purposes. They may even want to get work done on devices they do n...

• Prerequisites for Account management via an IPhone App?

  - by Icky

  Hello. I have been reading a couple of threads for this topic on this site. I want to create an App, which communicates with a server and has the following features: the User can create/manage an account on the server the App communicates with the server via a secure connection the User is updated about important news through messages From what I understood so far, I need to take care of the following: establish a secure connection with the server send account information(user data, password) to the server and authenticate the client side management and encryption of account data/information is handled by the server, so the App only sends data, the server stores/encrypts (no need for me to take care of anything) So far, I think, I have covered the most important features. I have read, that NSURLConnection can be used, to send the authentication data. But how is further communication ensured? And how is the encryption managed? Are there any useful tutorials on this, because this is the first time I delve into this topic, and any guidance is greatly appreciated! Also, if I have missed anything important (e.g. with managing accounts) please tell me.

• Azure : The process cannot access the file "" because it is being used by another process.

  - by Shantanu

  Hi all, I am trying to get a matlab-compiled exe running on Azure cloud, and for that purpose need to get a v78.zip onto the local storage of the cloud and unzip it, before I can try to run an exe on the cloud. The program works fine when executed locally, but on deployment gives and error at line marked below in the code. The error is : The process cannot access the file 'C:\Resources\directory\cc0a20f5c1314f299ade4973ff1f4cad.WebRole.LocalStorage1\v78.zip' because it is being used by another process. Exception Details: System.IO.IOException: The process cannot access the file 'C:\Resources\directory\cc0a20f5c1314f299ade4973ff1f4cad.WebRole.LocalStorage1\v78.zip' because it is being used by another process. The code is given below: string localPath = RoleEnvironment.GetLocalResource("LocalStorage1").RootPath; Response.Write(localPath + " \n"); Directory.SetCurrentDirectory(localPath); CloudBlob mblob = GetProgramContainer().GetBlobReference("v78.zip"); CloudBlockBlob mbblob = mblob.ToBlockBlob; CloudBlob zipblob = GetProgramContainer().GetBlobReference("7z.exe"); string zipPath = Path.Combine(localPath, "7z.exe"); string matlabPath = Path.Combine(localPath, "v78.zip"); IEnumerable<ListBlockItem> blocklist = mbblob.DownloadBlockList(); BlobStream stream = mbblob.OpenRead(); FileStream fs = File.Create(matlabPath); (Exception occurs here) It'll be great help if someone could tell me where I'm going wrong. Thanks! Shan

• Linux & Windows Boot Up Times in Amazon Web Service and Windows Azure

  - by Adron

  I've been working with Windows Azure and Amazon Web Services EC2 for a good many months now (almost getting to the years range) and I've seen something over and over that seems troubling. With AWS & Linux I commonly get instance startup times with EC2 around the 1-3 minute range. With AWS & Windows OS on an EC2 instance it often takes 10-20 minutes. With Windows Azure Web or Service Role I often get anywhere from 6-30 minutes waiting for a role to startup. I assume of course this involves booting up a windows instance somewhere in the fabric. I know there has always been tons of FUD about windows vs. Linux, but I'd really like to know why it is that Windows 08 or 03 boots so much slower in the cloud than Linux. Any specific technical information regarding this would be greatly appreciated! Thanks.

• MySQL is killing the server IO.

  - by OneOfOne

  I manage a fairly large/busy vBulletin forums (~2-3k requests per second, running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site. The last idea I can think of is using replication, but I'm not sure how much that would help and worried about database sync. I'm out of ideas, any tips on how to improve the situation would be highly appreciated. Specs : Debian Lenny 64bit ~12Ghz (6 cores) CPU, 7520gb RAM, 160gb disk.

• How should I host a site that could potentially get a short spike in traffic of 1000%+

  - by James Simpson

  This is a purely theoretical question, but what if I had a site that would normally only get a couple thousand hits a day, but for a few days each month that could shoot to several hundred thousand or even several million hits over the period of 1-3 days. The site would be pretty bare-bones (as in, 2-3 total pages with 1-2 max MySQL queries on each page and some PHP), so bandwidth wouldn't be the issue, but sheer volume taking down the site would be the main concern. Cloud hosting seems like the best way to go, but would something like Amazon EC2, MediaTemple, or something else be the right choice in this case?

• UEC - Can the Cluster Controller and Storage Controller be seperate systems?

  - by Jeremy Hajek

  My department is implementing an Ubuntu Enterprise Cloud. I have done the testing and am quite comfortable with the 4 pieces, CC/SC, CLC, WS, NC. Looking at various documents below it appears the the Storage Controller and Cluster Controller (eucalyptus-sc and eucalyptus-cc) are always installed on the same system. My question is this: can I install the storage controller and the cluster controller on separate systems? http://open.eucalyptus.com/wiki/EucalyptusAdvanced_v2.0 the picture indicates that cc and sc are two different machines http://www.canonical.com/sites/default/files/active/Whitepaper-UbuntuEnterpriseCloudArchitecture-v1.pdf P.10 1st paragraph uses the word "machine(s)" http://software.intel.com/file/31966 P. 8 indicates the same separate architecture BUT... https://help.ubuntu.com/community/UEC/PackageInstallSeparate indicates below that the SC and CC are to be on the same system.

• Automatic time tracking with central server, web reports

  - by user124209

  I need a software for automatic time tracking on Windows. With the following features: It should record time spent using the computer each day. Start time and end time. It should record what programs the employee used and total time for that program for specified period of time. It must have a centralized server that collects and stores all data. It could be a cloud server outside of a company network. It must have a web interface for viewing the monthly reports (the last but the most important requirement!). A nice feature to have would be an automatic generation of timesheets and Mac OS X support. I am looking to use it for a small team, this is not for personal use. Does anybody knows about software with these features?

• How can I access my music anywhere?

  - by musicfreak

  So here's the idea: I use multiple computers on an almost daily basis. I would like to be able to access my entire music library from any of those computers through the Internet. Is there a service or perhaps some software that would allow me to host my music "in the cloud", or in some other way access it from a different computer? I've searched for something like this and the closest I've found is the Media Player application found in Opera Unite, but that requires my home computer to be turned on at all times, which is less than ideal. I'm willing to pay, but not so much that I could just rent a private server for a lower price. Thanks in advance.

• What are the challenges when my enterprise desires to move the processing component of an applicatio

  - by Berkay

  Assume that i have an enterprise accounting application that consists of a front-end interface, a processing tier, and a back-end database. This is an application that contains private business data, and thus is traditionally run in a secure private network environment within the enterprise. What are the challenges that appear when my enterprise desires to move the processing component of this application to a cloud computing data center in order to achieve greater scalability or to reduce IT costs ? Pls note: do i have to make significant changes to my own infrastructure to enable external access to formerly private resources? do i have to modify the application code to handle new network topology ? thanks, if you give your answers in a simple manner, really appreciated.

• Problem with Xen, xvda and sda

  - by Javier J. Salmeron Garcia

  I am creating a cloud for my university using Eucalyptus with Xen (PCs have Debian Squeeze 64 bit installed). I have a problem with the following guest configuration: # # Configuration file for the Xen instance evenmorefinalfoo, created # by xen-tools 4.2 on Thu May 26 11:03:06 2011. # # # Kernel + memory size # kernel = '/boot/vmlinuz-2.6.32-5-xen-amd64' ramdisk = '/boot/initrd.img-2.6.32-5-xen-amd64' vcpus = '1' memory = '128' # # Disk device(s). # root = '/dev/sda2 ro' disk = [ 'file:/home/xen/domains/evenmorefinalfoo/disk.img,sda2,w', 'file:/home/xen/domains/evenmorefinalfoo/swap.img,sda1,w', ] As you can see, the disk and swap images are meant to be mounted on sda1 and sda2. However, when I start the guest, these are mounted on xvda1 xvda2, provoking an error. Is there anything that I can do about that? It seems like it is a Xen error. Thank you in advance,

• Keeping rackspace vserver alive

  - by mit

  It appears to me that rackspace somehow freezes cloud VMs after some idle time. This means the first page request to a php page takes much longer to respond than the subsequent requests. I am actually querying a machine with wget from a different host now to keep it "alive". But I wonder what frequency would be necessary. Does anyone know the time period after which they send a VM to "sleep"? I guess it would be some minutes. EDIT: There is no caching involved on the php site. It just recently moved from another vhost and there was never such latency on the first request.

• Azure Linux Virtual Machines Price per Hour, Computation or Running?

  - by Arjun Bajaj

  first of all, I couldn't find a StackExchange site on Cloud Computing. I think this is the most appropriate site, because some of you might be using Azure. So I just wanted to know: The Windows Azure Pricing Page shows Linux Virtual Machine Price as $0.013/hr for an extra small VM. The monthly price comes up to about $10. Is this price charged as number of hours of computation done on the VM or number of hours of running the VM? And if I shutdown the VM, will I be charged anything?

• How to make a vm scale when demand for resource increases

  - by Cray XT3

  i am having a server with 16 virtual core and 24G RAM,using Xen virtualization and ubuntu as dom0 Created 4 VMs (in para mode),each with different applications. CPU Load vary on each vm,somtimes first vm reaches nearly 100% CPU and others under 25% or even less. So is there a way in which vm can get cpu from other vms when they are not actually using it or utilization is under 25%.Same in the case of RAM also. I am not sure whether i am mentioning Cloud here. Initially i would like to give every vm a single VCPU,but can scale up to 8 or more by taking cpu from other vms if they are not using it. Is there any kind of tool that makes vm to scale its resources when demand increases. Is cloudstack and openstack designed for these kind of purpose or is that just a GUI to manage VMs.

• Best Solution For My Requirements

  - by Eray

  Hello, I'm a web developer. I have a few small online web application and a few Wordpress blogs. But i don't have too much experience with installing / configuring web servers . One of my web application needs cron jobs. It will check a lot of web sites availability. And, this application will leech too much RAM. And i think shared-hosting isn't suitable for this. But 1GB storage is enough i think. I don't need too much storage for my web sites. What do you think ? Which hosting solution is more suitable for my requirements ? Reseller ? VPS ? Cloud Server ? etc ...

• Using the same local folder for Dropbox and Skydrive

  - by roryok

  Ever since I switched to windows phone I've sorely missed having an official dropbox app. Recently I've toyed with the idea of moving all my crucial files to SkyDrive instead. I have more storage on SkyDrive and the WP SkyDrive integration is very handy. I'm thinking about having both cloud sync services point to the same local folder for the first few weeks. That way if I want to go back its an easy task (and I can keep using dropbox's superior public folder) Has anyone else done this? Are there any potential issues (permissions, conflicts etc)

• Is virtual machine slower than the underlying physical machine?

  - by Michal Illich

  This question is quite general, but most specifically I'm interested in knowing if virtual machine running Ubuntu Enterprise Cloud will be any slower than the same physical machine without any virtualization. How much (1%, 5%, 10%)? Did anyone measure performance difference of web server or db server (virtual VS physical)? If it depends on configuration, let's imagine two quad core processors, 12 GB of memory and a bunch of SSD disks, running 64-bit ubuntu enterprise server. On top of that, just 1 virtual machine allowed to use all resources available.

• Hosting solution for startup social app?

  - by happyhardik

  We are in a process of building up a social app. Initially we will have only a few thousands of users than will grow with time. Which would be the best and suitable hosting for this purpose? Grid, cloud or VPS? (it has to be economic, as we are just starting up) The hosting needs to be strong, so, in case our app has increase in the user base all of a sudden it wont break up or slow down the app. Our app is in PHP, MySQL. Sorry, if question posted in wrong place. Thanks, for your time. :)

• FTP Server with MySQL access, and POST notification

  - by TIW

  Im looking for an FTP server solution, that we can host either internally on a dedicated server, or on Rackspace Cloud/AWS, that provides a HTTP POST notification when a file is uploaded, and allows user accounts to be created either through an API or MySQL database. There are several offerings that provide email notification - but has anyone come across anything that matches the above requirements. BrickFTP being a IaaS system is an option, but we would prefer something hosted in house. I don't believe the standard FTP servers provided with Apache can do the above ... can they?

• Data storage solutions for rapidly running out of space

  - by Grimlockz

  I have 2 web servers (1 live and other backup), the issue I have is our storage is rapidly running out. All the data on the server is used by our customers and new documents are uploaded to the server daily. So nothing can be deleted as it's always in use. We use a flat file structure with no database. I'm seeking solutions or ideas for the best place to move the our data to. The data has to be secure and needs to run on a linux environment. Not sure where to start - clusters, vmware, or they such solutions for huge file servers?

• Solution for file store needing large number of simultaneous connections

  - by Tennyson H

  So I'm fairly new to large-scale architectures. We're currently using linode instances for our project, but we're brainstorming about scaling. We need a file store system than can deliver ~50mb folders (user data) to our computing instances in a reasonable amount of time (<20 sec), and scale to 10000+ total users, and perhaps 100+ simultaneous transfers. We are also unsure whether to network mount (sshfs/nfs) or just do a full transfer store-instance at the beginning and rsync instance- store at the end. I've experimented with SSH-FS between our little Linode instances but it seems to be bottlenecked at 15mb/s total bandwith, which wouldn't do under 10+ transfer stress let alone scale v. large. I also tried to investigate NFS but couldn't get it working but have little hope that it'll do within our linode network. Are there tools on other cloud providers that match our needs? Should we be mounting, or should we be transferring? Thanks very much!

• Javascript CS-PRNG - 64-bit random

  - by Jack

  Hi, I need to generate a cryptographically secure 64-bit unsigned random integer in Javascript. The first problem is that Javascript only allows 64-bit signed integers, so 9223372036854775808 is the biggest supported integer without going into floating point use I think? To fix this I can use a big number library, no problem. My Method: var randNum = SHA256( randBigInt(128, 0) ) % 2^64; Where SHA256() is a secure hash function and randBigInt() is defined below as a non-crypto PRNG, im giving it a 128bit seed so brute force shouldn't be a problem. randBigInt(n,s) //return an n-bit random BigInt (n>=1). If s=1, then the most significant of those n bits is set to 1. Is this a secure method to generate a cryptographically secure 64-bit random int? And importantly does taking the 2^64 mod guarantee 100% I have a 64-bit number? An abstract example, say this number is prime (it isn't i know), I will use it in the Galois Field [2^p], where p must be 64bits so that every possible 1-63bit number is a field element. In this query, my random int must be larger than any 63-bit number. And Im not sure im correct in taking the 2^64 mod of a 256bit hash output. Thanks (hope that makes sense)
