  • Unable to log in due to freeze, occasional error message

    - by Xianlin Xiong
    I'm new to Ubuntu. And I have some problems now. I downloaded Ubuntu 11.10 and burned it onto a CD. Then I load it in my conputer, it's easy. But when I finished those and restarted the computer, the problem comes: After I choose to log in the Ubuntu system,the screen stays in pink, and it can't jump into (about 30 min), and then I have no choices but to press Ctrl+Alt+Del to reboot. Another time I choose Ubuntu to log in, it shows on the screen that "BusyBox v1.18.4 ...... built-in shell ...... initramfs". However the Live CD works very well. What’s more, there is a Windows 7 partition on the hard drive. (Windows 7 is also okay.) But I leave more than 20GB on the hard drive to Ubuntu. When I installed Ubuntu, I only made two partitions (swap and /). I don’t know where the problems happened and how to deal with them. And I hope someone can help me out with the troubles.

  • Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

    - by ismaelf
    I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

  • Librated error when creating partition table

    - by Marko
    I bought a Dell Inspiron 5521 laptop a few days ago that came with Ubuntu preinstalled. I haven't used Ubuntu yet, and I don't have any experience in using it. I wanted to install Windows 7 64-bit on my laptop alongside Ubuntu, and made two bootable USB drives with Gparted and Windows 7. There wasn't a suitable partition on my laptop in which I could install Windows 7. I've read the instructions for using Gparted to create or manage my hard drive. I inserted the USB, booted from BIOS, and followed the procedure in installing Gparted. Then I entered Gparted, and the following error occurred: Librated error when Creating partition table. It asked me to click on either OK or Cancel. Either way I had my hard disk shown to me in the user window, in partitions that were made by the manufacturer: Partition File sys Label Size Flags /dev/sda1 fat32 dellutility 300.00 Mib diag /dev/sda2 fat32 os 3.00 Gib lba /dev/sda3 ext4 912.46 Gib boot /dev/sda4 extended 15.75 Gib (had a subpart) /dev/sda5 linux-swap 15.75 Gib ...and a option to switch to dev/sdb that's unused and of capacity 3Gib. I've used the biggest partition 912.46 Gib, and tried to reduce its size, and clicked OK. Then when I tried to make a new partition, it said it can't make any more partitions, no more than a maximum of 5. I would like to keep Ubuntu and slowly learn, but I also need to use programs that work in Windows. Thank you for taking the time to answer my question.

  • How to deal with bad developers who hold back the project

    - by ILovePaperTowels
    We're at the end of a project, but we continue to run into issues because of a single piece of the project. This piece is handled by a specific developer. Finally, we grabbed latest and started reviewing it. It's just horrendous code! Trying to step through it was difficult and it's a relatively simple workflow. The point of this question is, how to deal with this situation. The developer has a hard time accepting criticism (constructive or otherwise) and feels he is more knowledgeable than others on the team who are, well, highly decorated, experienced and accomplished developers. It's difficult to even get into a topic about development because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but it is a hard sell since devs are in short supply where we are and this is a corporation with a LOT of political bs. Management has been notified a few times but nothing is happening.

  • Ubuntu 12.04 (dual boot with Windows 7), doesn't boot after I deleted some files from Windows. What can I do?

    - by sacha
    The Ubuntu 12.04 I have installed (in Dual-Boot with Windows 7) using WUBI worked perfectly for over a month. Then it informed me that I ran out of space on the hard drive and I assumed it was because my hard drive on Windows was full. I logged into Windows and deleted the whole New Volume D. But now the problem is that it is not possible to log into Ubuntu but in Windows it's possible. I really paid attention about not deleting important files in Windows. When i try to log into Ubuntu : _either it does not go far and i have to restart the computer _or it goes until the loading time and a message says something like "[...] Graphics could not be detected [...]" and they ask to choose between 4 options including "Start with poor Graphics", "Reconfigure Graphics", "Troubleshoot" and "Restart the computer". But none of the options run and i also have to restart the computer manually from that point I have plenty of useful files in Ubuntu so i want to find another way to solve the problem instead of Uninstall/Reinstall Ubuntu. I want to know what happened ? And how to make it work ?

  • How to structure reading of commands given at a(n interactive) CLI prompt?

    - by Anto
    Let's say I have a program called theprogram (the marketing team was on strike when the product was to be named). I start that program by typing, perhaps not surprisingly, the program name as a command into a command prompt. After that, I get into a loop (from the users standpoint, an interactive command-line prompt), where one command will be read from the user, and depending on what command was given, the program will execute some instructions. I have been doing something like the following (in C-like pseudocode): main_loop{ in=read_input(); if(in=="command 1") do_something(); else if(in=="command 2") do_something_else(); ... } (In a real program, I would probably encapsulate more things into different procedures, this is just an example.) This works well for a small amount of commands, but let's say you have 100, 1000 or even 10 000 of them (the manual would be huge!). It is clearly a bad idea to have 10 000 ifs and else ifs after each other, for instance, the program would be hard to read, hard to maintain, contain a lot of boilerplate code... Yeah, you don't want to do that, so what approach would you recommend me to use (I will probably never use 10 000 commands in a program, but the solution should, at least preferably, be able to scale to that kind of massive (?) problems. The solution doesn't have to allow for arguments to the commands)?

  • One of my VMs went boom using Virtual Box and how it got fixed

    - by Enrique Lima
    I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

  • Why doesn't wireless work on Wubi 12.04 with a Broadcom BCM4312 card?

    - by Kristin
    I have recently set up ubuntu 12.04 on my laptop using the Wubi installer. I am having a very difficult time setting up a wireless internet connection. I am currently set up with an ethernet connection which I have used to download all new updates and to activate the Broadcom STA wireless driver. I have tried several things in the terminal based on other people's posts: ~$ rfkill list 0: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: yes ~$ rfkill unblock all It doesn't change anything. I also tried rebooting and connecting to the internet on my Windows Vista OS, and it worked, so I know that the connection should not be hard blocked. I have also tried installing b43 firmware (lp/phy version) that is supposed to work with my chip (BCM4312). It seems to have no effect. Then I tried: ~$ iwconfig lo no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:0 Noise level:0 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 eth0 no wireless extensions. This is my first time trying to work with ubuntu, so I would appreciate any help. Thanks. Also sorry this is poorly formatted. I'm having troubles with that too.

  • Resized Ubuntu 14.04 partition will not boot

    - by user292577
    First, a little background info: I intended to install Ubuntu alongside OS X, but I accidentally erased my entire hard drive and was left with Ubuntu alone. Yesterday, I finally tried to create a desperate partition and OS X. I successfully shrank my Ubuntu partition and created ~40 GB of free space. I used gparted to do this. At first I tried to use Internet Recovery to install OS X on the unallocated space I had created, but discovered I couldn't. I went back to gparted and created a FAT partition with that space. I'm pretty sure I actually did this using my Ubuntu partition on my hard drive (the one I had just shrunken), rather than the USB live boot I had used to shrink it. Therefore, at this point, I think my Ubuntu partition was still functioning properly. I went back to internet recovery and used disk utility to turn the FAT partition into a Mac OS Extended (Journaled) [HFS/HFS+] partition. I believe this is probably where the problem occurred. I successfully reinstalled OS X and found it to be fully functioning. However, when I tried to boot back into the Ubuntu partition all I got was a black screen with a little white cursor (it looks similar to a terminal screen/the Mac DFU mode, but I can't type anything into it. Is there anything I can do to repair my Ubuntu partition? If not, can I at least recover the data from it? Thank you for any help.

  • 12.04 doesn't boot anymore after a power failure

    - by Felix
    I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive? Ubuntu 12.04 64-bit Edit: it is ONLY Ubuntu on this Netbook, which uses the whole 500gb HDD as 1 Partition. Filesystem is NTFS. Whole Hardware seems okay. The USB drive which i used to instl the Os was formated in fat32

  • b43 Firmware Error when trying to install Ubuuntu 14.04 on XP Laptop

    - by WizardNo.7
    I know I'm an Ubuntu and Linux n00b, but I've been browsing the web for a few days searching for a solution, and none of the other b43 posts etc solve my problem. I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(It's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed(which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers, and then I get the usual: [ 95.514833] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found [ 95.514847] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found [ 95.514855] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all the instruction on this website. After this I have to hard reboot or shut-down. I don't have a previous Linux install so cannot do the apt-get from my previous install. I cannot access the boot options menu by using F6 or similar. Any ideas? Thanks beforehand!

  • Implementing Explosions

    - by Xkynar
    I want to add explosions to my 2D game, but im having a hard time with the architecture. Several game elements might be responsible for explosions, like, lets say, explosive barrels and bullets (and there might be chain reactions with close barrels). The only options i can come up with are: 1 - Having an array of explosions and treat them as a game element as important as any other Pros: Having a single array which is updated and drawn with all the other game element arrays makes it more organized and simple to update, and the explosive barrels at a first glance would be easy to create, simply by passing the explosion array as a pointer to each explosive barrel constructor Cons: It might be hard for the bullets to add an explosion to the vector, since bullets are shot by a Weapon class which is located in every mob, so lets say, if i create a new enemy and add it to the enemy array, that enemy will have a weapon and functions to be able to use it, and if i want the weapon (rocket launcher in this case) to have access to the explosions array to be able to add a new one, id have to pass the explosion array as a pointer to the enemy, which would then pass it to the weapon, which would pass it to the bullets (ugly chain). Another problem I can think of is a little more weird: If im checking the collisions between explosions and barrels (so i create a chain reaction) and i detect an explosion colliding with a barrel, if i add a new explosion while im iterating the explosions java will trow an exception. So this is kinda annoying, i cant iterate through the explosions and add a new explosion, i must do it in another way... The other way which isnt really well thought yet is to just add an explosive component to every element that might explode so that when it dies, it explodes or something, but i dont have good ways on implementing this theory either Honestly i dont like either the solutions so id like to know how is it usually done by actual game developers, sorry if my problem seems trivial and dumb.

  • Three Ubuntu 12.04 + Xfce problems

    - by user1708495
    sorry to bother you, but I wanted to set up a minimal Ubuntu 12.04 with minimal Xfce and probably due to my unawareness of several important things, not everything is working properly. -Sometimes when I shutdown I get error message from iwlwifi: It starts with a time out error about sending a power table and after several other errors it says "On demand firmware reload and "Unable to initialize device". And the shutdown stops there so I can only use hard shutdown. -Also when I boot, I often boot to a black screen, but pressing ctrl+alt+f1 gets me to the login prompt (I do not use a login manager). But then I sometimes cannot type. Seems probably more like a X server problem. When it works I only see the Plymouth splash for a very short time or sometimes not at all. -And the last problem is the most annoying one: Frequently Xfce freezes completely. I think ctrl+alt+f1 works sometimes, but other times I also have to use hard shutdown. When it freezes the cpu fan gets louder. I've been using Xbuntu for a while before, but with "real" Linux I am more a beginner, so I hope you forgive my questions Thanks

  • "drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6]" during install

    - by Warez J. Coxtrong
    I have a desktop PC which I built a while back. It has an Athlon XP 2500+, 2.5GB RAM, and an Nvidia (PNY Verto) Geforce 6200. I removed the CD drive to add another hard drive so I install from a USB flash drive. When I try to install 12.04 it seems to work just fine. The GUI boots up and wifi even connects to my router. I go through the language screen, the partition screen, the keyboard screen, the location screen, and the import my Windows settings screen just fine. But as soon as I'm done with all that the next screen goes black and displays this message: drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6] Since the GUI starts just fine earlier during the install, I know I shouldn't be having any display problems, but I am. How do I get Ubuntu to install properly? I have four IDE hard drives, all Western Digital: a 250GB, a 160GB, a 40GB occupied by Windows XP, and a 120GB that I'm trying to use for Ubuntu. 3GB of the 120GB drive are formatted for swap. I have checked the MD5sum of install image file and it all matches up. d791352694374f1c478779f7f4447a3f ubuntu-12.04-desktop-i386.iso

  • Where do I read more about building an architecture like Google has? [on hold]

    - by user107148
    I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

  • Trouble installing Ubuntu.

    - by CV13
    I have a blank 1TB hard drive that I have run ubuntu on before. I recently formatted it and am trying to reinstall Ubuntu 12.04 LTS on there. Using the Universal USB installer and the 64-bit iso file, I booted up my computer with only my 1TB hard drive connected. I go through the installation process normally, until I restart my computer at the end. Once restarted, I start to experience the problem deal with here. When I run it normally, it goes to a black screen with a blinking cursor. When I select the "Recovery Mode" option, a bunch of lines scroll across the screen, the last of which is "hostap_pci: Registered netdevice wifi0". It then stops there with a blinking cursor. When I follow the instructions on the page I linked to (replacing "quiet splash" with "nomodeset") and bunch of lines scroll through after I press Ctrl+x. The last line displayed is Adding 8386556k swap on /dev/sda5. Priority:-1 extents:1 across: 8386556k It then stops there with a blinking cursor. How do I fix this problem?

  • Surface development: it&rsquo;s just like software development

    - by Dennis Vroegop
    Surface is magic. Everyone using it seems to think that way. And I have to be honest, after working for almost 2 years with the platform I still get that special feeling the moment I turn on the unit to do some more work. The whole user experience, the rich environment of the SDK, the touch, even the look and feel of the Surface environment is so much different from the stuff I’ve been working on all my career that I am still bewildered by it. But… and this is a big but.. in the end we’re still talking about a computer and that needs software to become useful. Deep down the magic of the Surface unit there is a PC somewhere, running Windows Vista and the .net framework 3.5. When you write that magic software that makes the platform come alive you’re still working with .net, WPF/XNA, C#, VB.Net and all those other tools and technologies you know so well. Sure, the whole user experience is different from what you’ve known. And the way of thinking about users, their interaction and the positioning of screen elements requires a whole new paradigm. And that takes time. It took me about half a year before I had the feeling I got it nailed down. But when that moment came (about 18 months ago…) I realized that everything I had learned so far on software development still is true when it comes to Surface. The last 6 months I have been working with some people with a different background to start a new company. The idea was that the new company would be focussing on Surface and Surface only. These people come from a marketing background and had some good ideas for some applications. And I have to admit: their ideas were good. Very good. Where it all fell down of course is that these ideas need to be implemented in a piece of software. And creating great software takes skilled developers and a lot of time and money. That’s where things went wrong: the marketing guys didn’t realize and didn’t want to realize that software development is a job that takes skill. You can’t just hire a bunch of developers and expect them to deliver the best sort of software, especially not when it comes to Surface. I tried to explain that yes, their User Interface in Photoshop looked great, but no: I couldn’t develop an application like that in a weeks time. Even worse: the while backend of the software (WCF for communications, SQL Server for the database, etc) would take a lot more time than the frontend. They didn’t understand. It took them a couple of days to drawn the UI in Photoshop so in Blend I should be able to build the software in about the same amount of time. Well, you and I know that it doesn’t work that way. Software is hard to write, and even harder to write well, and it takes skill and dedication. It’s not something you can do as fast as you can draw a mock up for a Surface application in Photohop. The same holds true for web applications of course. A lot of designers there fail to appreciate the hard work that goes into writing the plumbing for a good web app that can handle thousands of users. Although the UI is very important, it’s not all there is to it. And in Surface development this is the same. The UI should create the feeling of magic, but the software behind it is what makes it come alive. And that takes time. A lot of time. So brush of you skills and don’t throw them away if you start developing for Surface. Because projects (and colaborations) can fail there as hard as they can in any other area of software development. On a side note: we decided to stop the colaboration (something the other parties involved didn’t appreciate and were very angry about) and decided to hire a designer for the Surface projects. The focus is back where it belongs: on the software development we know so well and have been doing very well for 13 years. UI is just a part of the whole project and not the end product. So my company Detrio is still going strong when it comes to develivering Surface solutions but once again from a technological background, not a marketing background.

  • No, iCloud Isn’t Backing Them All Up: How to Manage Photos on Your iPhone or iPad

    - by Chris Hoffman
    Are the photos you take with your iPhone or iPad backed up in case you lose your device? If you’re just relying on iCloud to manage your important memories, your photos may not be backed up at all. Apple’s iCloud has a photo-syncing feature in the form of “Photo Stream,” but Photo Stream doesn’t actually perform any long-term backups of your photos. iCloud’s Photo Backup Limitations Assuming you’ve set up iCloud on your iPhone or iPad, your device is using a feature called “Photo Stream” to automatically upload the photos you take to your iCloud storage and sync them across your devices. Unfortunately, there are some big limitations here. 1000 Photos: Photo Stream only backs up the latest 1000 photos. Do you have 1500 photos in your Camera Roll folder on your phone? If so, only the latest 1000 photos are stored in your iCloud account online. If you don’t have those photos backed up elsewhere, you’ll lose them when you lose your phone. If you have 1000 photos and take one more, the oldest photo will be removed from your iCloud Photo Stream. 30 Days: Apple also states that photos in your Photo Stream will be automatically deleted after 30 days “to give your devices plenty of time to connect and download them.” Some people report photos aren’t deleted after 30 days, but it’s clear you shouldn’t rely on iCloud for more than 30 days of storage. iCloud Storage Limits: Apple only gives you 5 GB of iCloud storage space for free, and this is shared between backups, documents, and all other iCloud data. This 5 GB can fill up pretty quickly. If your iCloud storage is full and you haven’t purchased any more storage more from Apple, your photos aren’t being backed up. Videos Aren’t Included: Photo Stream doesn’t include videos, so any videos you take aren’t automatically backed up. It’s clear that iCloud’s Photo Stream isn’t designed as a long-term way to store your photos, just a convenient way to access recent photos on all your devices before you back them up for real. iCloud’s Photo Stream is Designed for Desktop Backups If you have a Mac, you can launch iPhoto and enable the Automatic Import option under Photo Stream in its preferences pane. Assuming your Mac is on and connected to the Internet, iPhoto will automatically download photos from your photo stream and make local backups of them on your hard drive. You’ll then have to back up your photos manually so you don’t lose them if your Mac’s hard drive ever fails. If you have a Windows PC, you can install the iCloud Control Panel, which will create a Photo Stream folder on your PC. Your photos will be automatically downloaded to this folder and stored in it. You’ll want to back up your photos so you don’t lose them if your PC’s hard drive ever fails. Photo Stream is clearly designed to be used along with a desktop application. Photo Stream temporarily backs up your photos to iCloud so iPhoto or iCloud Control Panel can download them to your Mac or PC and make a local backup before they’re deleted. You could also use iTunes to sync your photos from your device to your PC or Mac, but we don’t really recommend it — you should never have to use iTunes. How to Actually Back Up All Your Photos Online So Photo Stream is actually pretty inconvenient — or, at least, it’s just a way to temporarily sync photos between your devices without storing them long-term. But what if you actually want to automatically back up your photos online without them being deleted automatically? The solution here is a third-party app that does this for you, offering the automatic photo uploads with long-term storage. There are several good services with apps in the App Store: Dropbox: Dropbox’s Camera Upload feature allows you to automatically upload the photos — and videos — you take to your Dropbox account. They’ll be easily accessible anywhere there’s a Dropbox app and you can get much more free Dropbox storage than you can iCloud storage. Dropbox will never automatically delete your old photos. Google+: Google+ offers photo and video backups with its Auto Upload feature, too. Photos will be stored in your Google+ Photos — formerly Picasa Web Albums — and will be marked as private by default so no one else can view them. Full-size photos will count against your free 15 GB of Google account storage space, but you can also choose to upload an unlimited amount of photos at a smaller resolution. Flickr: The Flickr app is no longer a mess. Flickr offers an Auto Upload feature for uploading full-size photos you take and free Flickr accounts offer a massive 1 TB of storage for you to store your photos. The massive amount of free storage alone makes Flickr worth a look. Use any of these services and you’ll get an online, automatic photo backup solution you can rely on. You’ll get a good chunk of free space, your photos will never be automatically deleted, and you can easily access them from any device. You won’t have to worry about storing local copies of your photos and backing them up manually. Apple should fix this mess and offer a better solution for long-term photo backup, especially considering the limitations aren’t immediately obvious to users. Until they do, third-party apps are ready to step in and take their place. You can also automatically back up your photos to the web on Android with Google+’s Auto Upload or Dropbox’s Camera Upload.

  • How to find domain registrar and DNS hosting with good DNSSEC support?

    - by rsp
    Simplified problem I want to buy a domain and make a website that is fully secured with DNSSEC. Background I've been hearing about the insecurity of DNS for years. I've watched all of the talks by Dan Kaminsky and others from DNS exploits to The future of DNS Security Panel. I knew that using DNS without security is a disaster waiting to happen. I followed the development of the DNSSEC standard. I celebrated the key signing ceremony. Everything was on the right track to finally have a secure DNS system in place. And now more than 2 years later I wanted to just do what everyone said I should do: use DNSSEC for a new domain. So I need a domain registrar and a DNS hosting service that supports DNSSEC. Surprisingly it is not that easy to even find out who does support DNSSEC. It was actually much easier to find info on DNSSEC two years ago when everyone was going to support DNSSEC Real Soon Now but now years passed and I hardly see any progress done. I just hope that I was just looking in the wrong places and someone here will explain all of the doubts. I hope that other people who want to have a secure website will also find this question useful. What is needed registrar and DNS servers with full DNSSEC support for .com domains What is not needed IPv6 support Web hosting anything more What I found out so far Go Daddy offers Premium DNS service for additional $36 per year that lets you "Secure up to 5 domains with DNSSEC". easyDNS has DNSSEC available in Beta across all service levels (you need to enable the "beta" flag in configuration) but it doesn't seem to be production ready and judging from the lack of updates it isn't a feature of highest priority (the last update from March 2011 on the easyDNS blog). Name.com - according to The Register (US domain registrar does IPv6, DNSSEC) it has DNSSEC support since 2010 but right now (October 2012) I couldn't find anything related to DNSSEC on their website. Dynadot that is very often recommended doesn't support DNSSEC Namecheap that is also often recommended doesn't support DNSSEC. The support answer from 2011 suggested that it was being added but in 2012 still no ETA is given to customers. DynDNS was supposed to support DNSSEC, I found a link explaining DNSSEC support but it gives 404 Not Found page and offers a search box - when searching for DNSSEC I get "No results were found for your query." GKG was recommended online for DNSSEC support but it's hard to find any information on the level of DNSSEC support - there is a brief explanation on what is DNSSEC and how to sign Delegation Signer records in their FAQ but no information about the level of actual support can be found. Ask Slashdot: Which Registrars Support DNSSEC? from July 2011 - Answers list Go Daddy, DynDNS, GKG, Name.com as registrars that support DNSSEC but: see above. Related questions How to find web hosting that meets my requirements? What is needed to add DNSSEC to my site? DNS hosting better managed by Domain provider or Hosting provider? Registrar with good security, DNS hosting, and DNSSEC and IPv6 resolvers? In no. 1 no one is ever mentioning DNS at all. In no. 2 answers only mention the .se TLD, there are very few answers and they seem very outdated. In no. 3 one answer says "On projects that demand higher security, I might look for a web host that supports DNSSEC" but no more information is provided. The only relevant answers are in no. 4 where easyDNS is recommended by someone who has never used them personally. Meanwhile, as of October 2012, the support of DNSSEC is described as "in beta" on the easyDNS feature list. Another one recommends SiteGround but searching their site for DNSSEC returns no results. Other answers recommend web hosting providers that don't meet the requirement of DNSSEC support. Also the question mentioned above lists 9 very specific requirements other than only DNSSEC (like eg. HTTP-only login cookies, two-factor authentications, no DNS record limits, DNS statistics of queries/day, audit trails etc.) which might have excluded many possible recommendations if one is only interested in DNSSEC support. Conclusions I thought that by the end of 2012 the support of DNSSEC among domain registrars and DNS providers would be nearly universal. I am shocked that the support seems virtually nonexistent. Is this a result of some serious problems with the DNSSEC adoption? Or is it just not a hot topic and no one bothers anymore? According to the DNSSEC Scoreboard roughly about 0.1% of .com domains support DNSSEC. Could that be caused by the lack of DNSSEC support among registrars and DNS providers, is the information too hard to find or maybe no one cares? There is even no "dnssec" tag here. Questions The information is surprisingly hard to find. That is why I am asking for first-hand experience and personal recommendations. Has anyone here actually set up a website with DNSSEC, from the domain registration to the configuration of DNS servers? Can anyone recommend any of the registrars mentioned above? Can anyone recommend any registrar not mentioned above?

  • How big can my SharePoint 2010 installation be?

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). 3 years ago, I had published “How big can my SharePoint 2007 installation be?” Well, SharePoint 2010 has significant under the covers improvements. So, how big can your SharePoint 2010 installation be? There are three kinds of limits you should know about Hard limits that cannot be exceeded by design. Configurable that are, well configurable – but the default values are set for a pretty good reason, so if you need to tweak, plan and understand before you tweak. Soft limits, you can exceed them, but it is not recommended that you do. Before you read any of the limits, read these two important disclaimers - 1. The limit depends on what you’re doing. So, don’t take the below as gospel, the reality depends on your situation. 2. There are many additional considerations in planning your SharePoint solution scalability and performance, besides just the below. So with those in mind, here goes.   Hard Limits - Zones per web app 5 RBS NAS performance Time to first byte of any response from NAS must be less than 20 milliseconds List row size 8000 bytes driven by how SP stores list items internally Max file size 2GB (default is 50MB, configurable). RBS does not increase this limit. Search metadata properties 10,000 per item crawled (pretty damn high, you’ll never need to worry about it). Max # of concurrent in-memory enterprise content types 5000 per web server, per tenant Max # of external system connections 500 per web server PerformancePoint services using Excel services as a datasource No single query can fetch more than 1 million excel cells Office Web Apps Renders One doc per second, per CPU core, per Application server, limited to a maximum of 8 cores.   Configurable Limits - Row Size Limit 6, configurable via SPWebApplication.MaxListItemRowStorage property List view lookup 8 join operations per query Max number of list items that a single operation can process at one time in normal hours 5000 Configurable via SPWebApplication.MaxItemsPerThrottledOperation   Also you get a warning at 3000, which is configurable via SPWebApplication.MaxItemsPerThrottledOperationWarningLevel   In addition, throttle overrides can be requested, throttle overrides can be disabled, and time windows can be set when throttle is disabled. Max number of list items for administrators that a single operation can process at one time in normal hours 20000 Configurable via SPWebApplication.MaxItemsPerThrottledOperationOverride Enumerating subsites 2000 Word and Powerpoint co-authoring simultaneous editors 10 (Hard limit is 99). # of webparts on a page 25 Search Crawl DBs per search service app 10 Items per crawl db 25 million Search Keywords 200 per site collection. There is a max limit of 5000, which can then be modified by editing the web.config/client.config. Concurrent # of workflows on a content db 15. Workflows running in the timer service are not counted in this limit. Further workflows are queued. Can be configured via the Set-SPFarmConfig powershell commandlet. Number of events picked by the workflow timer job and delivered to workflows 100. You can increase this limit by running additional instances of the workflow timer service. Visio services file size 50MB Visio web drawing recalculation timeout 120 seconds Configurable via – Powershell commandlet Set-SPVisioPerformance Visio services minimum and maximum cache age for data connected diagrams 0 to 24 hours. Default is 60 minutes. Configurable via – Powershell commandlet Set-SPVisioPerformance   Soft Limits - Content Databases 300 per web app Application Pools 10 per web server Managed Paths 20 per web app Content Database Size 200GB per Content DB Size of 1 site collection 100GB # of sites in a site collection 250,000 Documents in a library 30 Million, with nesting.

  • How to Sync Any Folder With SkyDrive on Windows 8.1

    - by Chris Hoffman
    Before Windows 8.1, it was possible to sync any folder on your computer with SkyDrive using symbolic links. This method no longer works now that SkyDrive is baked into Windows 8.1, but there are other tricks you can use. Creating a symbolic link or directory junction inside your SkyDrive folder will give you an empty folder in your SkyDrive cloud storage. Confusingly, the files will appear inside the SkyDrive Modern app as if they were being synced, but they aren’t. The Solution With SkyDrive refusing to understand and accept symbolic links in its own folder, the best option is probably to use symbolic links anyway — but in reverse. For example, let’s say you have a program that automatically saves important data to a folder anywhere on your hard drive — whether it’s C:\Users\USER\Documents\, C:\Program\Data, or anywhere else. Rather than trying to trick SkyDrive into understanding a symbolic link, we could instead move the actual folder itself to SkyDrive and then use a symbolic link at the folder’s original location to trick the original program. This may not work for every single program out there. But it will likely work for most programs, which use standard Windows API calls to access folders and save files. We’re just flipping the old solution here — we can’t trick SkyDrive anymore, so let’s try to trick other programs instead. Moving a Folder and Creating a Symbolic Link First, ensure no program is using the external folder. For example, if it’s a program data or settings folder, close the program that’s using the folder. Next, simply move the folder to your SkyDrive folder. Right-click the external folder, select Cut, go to the SkyDrive folder, right-click and select Paste. The folder will now be located in the SkyDrive folder itself, so it will sync normally. Next, open a Command Prompt window as Administrator. Right-click the Start button on the taskbar or press Windows Key + X and select Command Prompt (Administrator) to open it. Run the following command to create a symbolic link at the original location of the folder: mklink /d “C:\Original\Folder\Location” “C:\Users\NAME\SkyDrive\FOLDERNAME\” Enter the correct paths for the exact location of the original folder and the current location of the folder in your SkyDrive. Windows will then create a symbolic link at the folder’s original location. Most programs should hopefully be tricked by this symbolic location, saving their files directly to SkyDrive. You can test this yourself. Put a file into the folder at its original location. It will be saved to SkyDrive and sync normally, appearing in your SkyDrive storage online. One downside here is that you won’t be able to save a file onto SkyDrive without it taking up space on the same hard drive SkyDrive is on. You won’t be able to scatter folders across multiple hard drives and sync them all. However, you could always change the location of the SkyDrive folder on Windows 8.1 and put it on a drive with a larger amount of free space. To do this, right-click the SkyDrive folder in File Explorer, select Properties, and use the options on the Location tab. You could even use Storage Spaces to combine the drives into one larger drive. Automatically Copy the Original Files to SkyDrive Another option would be to run a program that automatically copies files from another folder on your computer to your SkyDrive folder. For example, let’s say you want to sync copies of important log files that a program creates in a specific folder. You could use a program that allows you to schedule automatic folder-mirroring, configuring the program to regularly copy the contents of your log folder to your SkyDrive folder. This may be a useful alternative for some use cases, although it isn’t the same as standard syncing. You’ll end up with two copies of the files taking up space on your system, which won’t be ideal for large files. The files also won’t be instantly uploaded to your SkyDrive storage after they’re created, but only after the scheduled task runs. There are many options for this, including Microsoft’s own SyncToy, which continues to work on Windows 8. If you were using the symbolic link trick to automatically sync copies of PC game save files with SkyDrive, you could just install GameSave Manager. It can be configured to automatically create backup copies of your computer’s PC game save files on a schedule, saving them to SkyDrive where they’ll be synced and backed up online. SkyDrive support was completely rewritten for Windows 8.1, so it’s not surprising that this trick no longer works. The ability to use symbolic links in previous versions of SkyDrive was never officially supported, so it’s not surprising to see it break after a rewrite. None of the methods above are as convenient and quick as the old symbolic link method, but they’re the best we can do with the SkyDrive integration Microsoft has given us in Windows 8.1. It’s still possible to use symbolic links to easily sync other folders with competing cloud storage services like Dropbox and Google Drive, so you may want to consider switching away from SkyDrive if this feature is critical to you.

  • A Visual Studio Release Grows in Brooklyn

    - by andrewbrust
    Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan.  Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn.  How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that.  NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that.  Likewise, while Office 2010 is a product whose value is apparent.  Appreciating VS 2010’s value takes a bit more savvy.  Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product.  How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers?  Well, it can be tough.  Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons.  Support fro SharePoint development is a big one.  In previous versions of VS, that support has been anemic, at best.  Shortage of SharePoint developers is a huge issue in the industry, and this should help.  There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform.  ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS.  So too does jQuery, the Open Source environment that makes JavaScript development a breeze.  The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection.  If you’re not a developer, this may sound confusing and minute.  I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features.  This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug.  Cool?  Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done.  Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred.  VS 2010 allows all that.  This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s.  His answer was an earnest “we don’t think so.”  If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it.  It will make software development much cheaper and more efficient.  Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now.  There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7.  With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age.  How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely?  Hard to say.  But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK.  And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics?  I honestly don’t know, because it’s the market’s prerogative to pass that judgement.  I can say this though: based on today’s show, I think Microsoft’s been doing its homework.
