• Error related to pkg-config when installing frei0r as part of another package

  - by Anentropic

  I am trying to build https://github.com/mltframework/shotcut on OS X Lion (using their script in scripts/build_shotcut.sh) and after numerous hurdles I'm stuck on this error: ./configure: line 16062: syntax error near unexpected token `OPENCV,' ./configure: line 16062: `PKG_CHECK_MODULES(OPENCV, opencv >= 1.0.0, HAVE_OPENCV=true, true)' ERROR: Unable to configure frei0r From what I already googled this means that the PKG_CHECK_MODULES macro hasn't been defined, which probably means there's something wrong with my pkg-config, which I installed via Homebrew. Sounds like the pkg.m4 file isn't found. When I brew install pkg-config I get the following warning: Warning: m4 macros were installed to "share/aclocal". Homebrew does not append "/usr/local/share/aclocal" to "/usr/share/aclocal/dirlist". If an autoconf script you use requires these m4 macros, you'll need to add this path manually. Well I've appended that line to the dirlist file and it doesn't fix the problem above. Can anyone suggest a way forward here? I have briefly tried building my own pkg-config from source but (bizarrely) when I tried to ./configure I got the following error: checking for pkg-config... no ./configure: line 13540: --exists: command not found configure: error: pkg-config and glib-2.0 not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values if building pkg-config needs pkg-config it seems like a weird catch 22 situation... I think this is probably an unnecessary sidetrack anyway.

• Connection problems via Wifi (multiple devices)

  - by Kelvin Farrell

  I'm having connection issues with my router (Linksys WRT610N) at home. There are a number of things that are happening (may be more, this is just what I've mainly noticed)... 1) Using my laptop (Macbook Pro OSX Lion), I am unable to complete any operations with my external FTP server, hosted with FatCow. I can connect to it, navigate through all the files, but when I try to edit/delete/add a file the operation times out. EVERY time. I've used two other Wifi connection on my laptop and neither have this issue. 2) I am unable to upload photos/videos to Facebook or Twitter using my phone (Samsung Galaxy S2) or my tablet (HP Touchpad - CM9). Neither am I able to upload files to Dropbox via either of the devices. Same thing happens in all situations; the upload will begin and it will just hang on 0% forever. After about 10 mins I am always forced to disconnect the Wifi to stop the action. 3) My laptop is having slow internet speed, even though we are on 20mb broadband. Speedtests say I'm getting a good connection and my Ping is good, but when using streaming services like Spotify, it takes forever to load a page and frequently stops to buffer whilst playing a song. Don't know if it's worth mentioning but I have no issues with my XBox (Ethernet), AppleTV (Wifi) or my girlfrield's phone (Nokia Lumia 800 - WP7.5) on the network. I'd really appreciate any help. This is driving me insane and is really affecting both my working and leisure use of the internet.

• MacBook Pro and Backtrack 5R1 Configuration

  - by user119346

  I have a Macbook pro Quad core (2.2/8gb ram/750gb hdd). I have went through tons of forums on the Internet, but none of them seemed to be updated for the current Backtrack 5R1, or the question of getting it to correctly work on the MBP. Can anyone help? I don’t have a USB Dongle, and I want to be able to use the internal airport extreme wireless of the MBP to use BT 5R1. I have downloaded Backtrack 5R1 onto VMWare Fusion, and got it up and running, but to no avail. It keeps recognizing my card as a Ethernet connection. Kismac wont recognize the card either. So what I am asking for is this: The proper “download method.” for Backtrack 5R1 to my MacBook Pro. (YES I AM WILLING TO RE-DOWNLOAD BT 5R1). The Complete process from start to finish, UP TO DATE, from someone who has done this using an MBP Running Lion OSX. The proper tweaks, settings, or commands to get my airport extreme wireless card to work (it is BROADCOM 4331 I think). The wireless connection I need to use the tools on both Backtrack 5R1 and Kismac. I mainly need to test WEP cracking on my network for security. The difference between running BT 5R1 on VMWARE Fusion and running from downloading it directly to the MBP, if there is, How to download it directly to the MBP?

• 2011 i7 Macbook Pro unable to boot from any Windows CD?

  - by Craig Otis

  I'm encountering issues installing Windows alongside my Lion install. I'm attempting to install from the internal SuperDrive, after using Boot Camp to partition what was a single, HFS+ volume. When holding down Option at boot, the CD appears in the startup list, but upon selecting it, I get a gray screen for 5 minutes, then a flashing white folder. I tried installing rEFIt and using this to boot the CD, but I receive an error about "Not Found" being returned from the "LocateDevicePath", and a mention of the firmware not supporting booting using legacy methods. In the Console, when opening the StartupDisk preference pane (which never presents the CD as a selectable option), I see: 11/25/11 4:39:31.159 PM System Preferences: isCDROM: 0 isDVDROM:1 11/25/11 4:39:31.159 PM System Preferences: mountable disk appeared: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.214 PM System Preferences: - So far so good, passing disk to System Searcher. 11/25/11 4:39:33.218 PM System Preferences: OSXCheck: No boot.efi in System Folder or volume root. 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD I'm at a loss here. I've done my research, but it sounds like most of the rEFIt errors of this nature are caused by installing from a thumbdrive, or an external drive. I'm using the internal SuperDrive. Also, I've tried this with two different disks: A Windows XP SP2 CD A Windows 7 x86 DVD Both are disks I've had around for years, and I've used them reliably in the past. The system is an early 2011 15" Macbook Pro, all firmware updates installed.

• hosts.deny ignored by MacOSX 10.8

  - by David Holm

  I have been trying to set up my MacOS X Server, which I recently upgraded to Mountain Lion, to use denyhosts as I need to open port 22 to it. denyhosts is set up and adds entries to /etc/hosts.deny so I decided to add my laptops IP to it in order to verify that it actually works but I can still log in and my IP shows up in /private/var/log/system.log. I even rebooted the server once just to be sure there wasn't some service that had to be restarted. I tried the following entries: ALL: <my laptop's IP> sshd: <my laptop's IP> sshd: 127.0.0.1 My /etc/sshd_config has the following parameters set: UsePAM yes UseDNS no I Googled if deny.hosts has been deprecated in OSX 10.7 or 10.8 but I couldn't find any indications that it has. Any ideas of what is going wrong or if there is an alternative way to achieve the same result? Yes, a private key would solve this problem but for the time being I would like to stick to using password authentication. I also like the idea of denyhosts actually blocking access to all services running on the server and not just ssh.

• Configuring SASL support in libmemcached

• How can I make non-anti-aliased text look good in Firefox on Mac OS X?

  - by cosmic.osmo

  After being a Windows user for the last 10 years, I got a MacBook Pro, which I'm working on configuring to my liking. I find small-size anti-aliased text to be blurry and hard to read, so I typically disable it. I've found the settings in the General Control Panel, and used TinkerTool to increase the anti-alias threshold size to 18pt. Mac OS X and other applications appear to respect these settings. A problem appears when I use Firefox. By default, it's configured to ignore the Mac OS anti-alias settings. This is changed by going to about:config, and setting gfx.use_text_smoothing_setting = true (default is false). However, even with this setting, it appears Firefox is still rendering the fonts under the assumption that they will be anti-aliased, which results in very odd and uneven spacing, as you can see in this example (pay attention to the placement of the "s" in "Disable"): With anti-aliasing: Without anti-aliasing: How can I configure Firefox to both not use anti-aliasing and to use correct font spacing? I'm using Mac OS X Lion and Firefox 5.

• Wake on Demand for Apache server in OS X 10.8

  - by Gary

  Mac OS X Mountain Lion does not have a Web Sharing box in the Sharing system prefs menu. It is thoroughly discussed on the web that the Apache server is available, and that it can be turned on manually in the command line, or by using a convenient Prefs Pane. That works while the computer is awake. But, when my computer goes to sleep, the server stops working, even though Wake for Network Access is checked in the Energy Saver Pref Pane. From the discussion on Bonjour, I see that this problem probably results from the fact that Apache isn't registered with Bonjour. Does that sound likely? If not, please make some suggestions. The connection is via hard-wired ethernet. If registration with Bonjour is the problem, I'd like to know how to register it. You gave a nice description of dns-sd, and the command description says dns-sd -R Name Type Domain Port [TXT...] (Register a service)", but I don't know what to use for "Name" or "Type", or the format of the domain. I tried some dns-sd -B searches and found nothing I could use as a model, and it doesn't show up in Bonjour Browser. Any suggestions would be appreciated.

• Outlook / Gmail 'too many simultaneous connections' error

  - by sam

  I'm just setting up Outlook for Mac, and I'm trying to add a Google Apps application for business email (Gmail). I've set it up correctly (same details worked in Mac mail). But I keep getting two errors, either or just a error asking for the username and password again. Just to confirm the user name and password are correct, although when I go into menu command Tools - Account and look in the password field for that account it's blank. But if I just click cancel on the popup asking for my username password it just continues to get mail in the background for about 30 seconds, before again asking again for the password, or showing the above error which I can click 'yes' to and again it will get the mail. But after 30 seconds it does the same thing. I've got two other accounts set up fine, one a horde account (hosted webmail using POP3) and the other a iCloud .me account running on IMAP. What might be causing this and how I can remedy it? A bit more background: the machine is a MacBook Pro running Mac OS X v10.7 (Lion). Update 2013-11-02 I've updated Outlook to SP3, but I still get the same error.

• Mac updated just now, postgres now broken

  - by user52224

  I run postgres 9.1 / ruby 1.9.2 / rails 3.1.0 on a maxbook air for local dev. It's all been running smoothly for months, (though this is the first time I've done development on a mac.) It's a macbook air from last year, and today I got the mac osx software update message as I have a few times before, and my system downloaded approx 450mb of updates and restarted. It now says it's on OSX 10.7.3. Point is, postgres has stopped working, when I start my thin server (mirror heroku cedar) as normal, and then browse to my rails app I get: PG::Error could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"? What happened? After browsing around a few questions I'm still confused, but here's some extra info: Running psql from command line gives same error I can run pgadmin 3 and connect via it and run SQL no problems Running which psql shows the version as /usr/bin/psql I created a PostgreSQL user back when I got the mac (it's always been on lion) I've no idea why, almost certainly I was following a tutorial which I neglected to store in my notes. Point is I am aware there is a _postgres user as well. I know it's rubbish, but apart from a note on passwords, I don't have any extra info on how I configured postgres - though the obvious implication is that I did not use the _postgres user. Anyone have suggestions or information on what might have changed / what I can try to debug and fix? Thanks. Edit: Playing around based on this question and answer: http://stackoverflow.com/questions/7975414/check-status-of-postgresql-server-mac-os-x, see this string of commands: $ sudo su postgreSQL bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data pg_ctl: another server might be running; trying to start server anyway server starting bash-3.2$ 2012-04-08 19:03:39 GMT FATAL: lock file "postmaster.pid" already exists 2012-04-08 19:03:39 GMT HINT: Is another postmaster (PID 68) running in data directory "/Library/PostgreSQL/9.1/data"? bash-3.2$ exit

• How to install Windows 7 on a MacBook with HDDs and no optical drive, without rEFIt

  - by user1238528

  I just removed the SuperDrive on my MacBook Pro and replaced it with an SSD. So now my laptop has a SSD, and a HDD, but no optical drive. I have Lion on the SSD and I want to install Windows 7 on the HDD. Unfortunately, Boot Camp only will install Windows off of the Windows DVD. I have made a bootable Windows 7 thumb drive but my MacBook Pro won’t boot off it. So my question is how can I install Windows on the other HDD? I have thought about maybe using Oracle VirtualBox to install it on that hard drive, but I don’t know if that would allow me to boot directly into Windows. I really don't want to go down the whole virtualization route. I know I could just take out the SSD, put back in the optical drive, run the Windows 7 DVD, take the optical drive back out, put the SSD back in. But that sounds like a nightmare. Also, I really don’t want to use things like rEFIt. Any advice?

• How do I connect to SSH without the password to be requested every time ? - Already follow some answers here but it doesn't work

  - by MEM

  MAC OS X Lion 10.7.3 1) On host, I've created an authorized_keys file inside .ssh folder, by doing: touch authorized_keys 2) I've copy my public ssh key into host .ssh folder by doing: scp ~/.ssh/mykey.pub [email protected]:/home/userhost/.ssh/mykey.pub 3) I've place it's contents inside authorized files by doing: cat mykey.pub >> authorized_keys 4) Then I've removed the mykey.pub file: rm mykey.pub 5) On my terminal, locally, inside my ~/.ssh folder I made: ssh-add mykey (notice that it is without the pub extension); 6) I've closed and opened again the terminal. When I first connect to this host, it has being added to the *known_hosts* file inside ~/.ssh; I've pico known_hosts and the hash is there. Still, every time I connect by doing: ssh [email protected] it requests a password ! What am I missing here ? UPDATE: I've done EVEN TWO MORE THINGS here: 7) Set your key to be the default identity - if it doesn't exist, create; touch ~/.ssh/config and place inside the following line: IdentityFile ~/.ssh/yourkeyname *id_rsa is normally your default key. You should switched to your key. This tells that the outgoing ssh connections should use this as a default identity.* 8) Add a bash process to your ssh-agent: ssh-agent bash ssh-add ~/.ssh/yourkeyname Lisinge answer helped but it's not definitive. If we restart our machine, the password gets prompted again!!! How can we debug this? What can we do here? How can we check where is this process failing ? UPDATE 2: If I use: ssh -v -i <keyfile> [email protected] I get among other things: OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 Warning: Identity file yourkeyname not accessible: No such file or directory. This message refers to what? The identify file is not accessible on the localhost, or it's not accessible on the remote host ? Please advice

• Wake a Mac display from sleep via SSH

  - by MaxGabriel

  I'm using Jenkins as a CI server, where I'm SSHing into an iMac running OS X Mountain Lion (10.8.4) to run some UIAutomation integrations tests on an iOS app. The iMac actually sits 10 ft from me (but across a table) so I'm able to see the screen. However, the tests don't wake up the display, so I often can't see them. Is there a way to wake up the display from the terminal once Jenkins has SSHed in? So far I have tried using Applescript to press an arrow key, and using the Wake Assist application. I also tried setting the wake schedule to be the current date. Finally, I tried using the caffeinate command: caffeinate -t 300 &. The computer's "Wake for Wi-Fi access" checkbox is enabled. So far my best workaround is to just set the iMac to stay awake for atleast 3 hours. However, it'd be nice to keep normal sleep behavior, as I hypothesize that the screen waking from sleep would alert me visually that the integration tests are running. It's also significantly cooler :)

• Mac OS X will only upload zero-byte files through FTP

  - by tabacitu

  I'm using Mac OS X Lion and i've been having this problem with FTP (any FTP client, mind you. I tried Transmit, FileZilla, Cyberduck and the Terminal, all with the same result) I can browse files in my FTP Client, but when I upload files, the client hangs for a few seconds, then thinks it uploaded the files successfully, but it only creates a new file with one blank line in it. Sometimes, it manages to upload 4-5 lines. It then returns: 226 - Error during read from data connection 226 Transfer aborted But 2xx is a success message. It is not a server issue, since any Windows machine will upload just fine using the same network. Can anybody figure out what the problem is? It renders my mac useless for web development. The problem persists with SFTP and FTP with SSL/TLS. Later edit: Solved! Ok, turns out the problem goes away when I take out my router and connect directly through PPPoE. So the problem is with the router, I thought. But no, the problem is with the mac that connects through a router that connects through a PPPoE and tries to upload using FTP. Pretty specific, I know. The problem is with the MTU (maximum transmission unit). Apparently, mac os x breaks the file into chunks that are too large for the router to send, because the router's MTU was set lower than Mac OS X's. My router's was 1492, which is ok, but my Mac's MTU was 1500, which is unacceptable. I don't even understand why it works directly with PPPoE. Anyway, if you encounter the same problem, this is how you diagnose and fix it: In terminal, run: ifconfig | grep mtu to see what the MTU is for en0 (or en1, mine was en0) If it's 1500, run sudo ifconfig en0 mtu 1300 This should solve it. If so, it may only be until the next restart. You can also change the MTU in System Preferences \ Network \ Ethernet - Advanced \ Hardware

• Cannot ssh into server

  - by revolver

  I am trying to SSH into a linux machine running ubuntu, but the interactive shell stuck somewhere and I can't key in anything. I am on Mac OS X Lion. This only happens when I am trying to access via an external IP. Local LAN SSH is working perfectly. macbook:~ user$ ssh -v -v user@serverip // i skipped the rest of the log, but I can paste it here again if needed.

I checked var/log/auth on the server and saw that the a session is being created and I had already logged in, but I don't see any responses on my client machine. I googled around and a lot of the solution had to do with the Broadcom wireless driver, but I am not even using one, so I am pretty clueless here. To give you more information, the linux machine is also running a web server, and I have no problem accessing the web server. Thanks. Any help is appreciated.

• Viewing local websites on my iOS device over Wi-fi

  - by John

  Trying to view some local html/css/js files in a mobile browser on my iOS device. Thought maybe file-sharing would be an option, and is, but I'm not completely satisfied with it. Any time I try to do the following an error occurs. Web sharing is on and available at http://192.168.1.101/~user but I have to manually copy the files in. If I try to symlink a folder in so that the address could be viewed at ''~user/some_dir by issuing $ ln -s /Users/user/dev/some_dir ~/Sites/ then I get a 403 forbidden error. I've tried to remedy this by modifying a user.conf file in /private/etc/apache2/ and using the following syntax: <Directory "/Users/user/Sites/"> Options Indexes MultiViews SymLinks AllowOverride None Order allow,deny Allow from all </Directory> but nope, still doesn't work. I get a 403 error. If I try to symlink each individual file in instead of using a directory as a sub-directory, same error. Any help would be greatly appreciated! I'd just like to symlink directories into the ~/Sites one and browse them on my iOS device over wifi. I'm on OS X 10.7 Lion trying to connect with iOS 5.

• Same script, different behavior [migrated]

  - by Antoine_935

  I just stumbled upon an interesting bug... Still trying to figure out what is exactly happening. Maybe you can help. First, the context. I'm currently building yet another man to html converter (for some reasons I won't motivate here, but I need it). So, have a look at the screenshot below (see the link), more precisely at the outlined spots. See? On the upper shell, I have &lt ; and &gt ;, that is, escaped html. While on the shell below I have < and directly. But as you can see (or do I seriously need looking glass ?), the command man 2 semget | webmanneris the same on both sides, as is the which webmanner. The two are executed roughly at the same moment, with no modification made to the script between. [Oops, cannot post pictures just yet... Here comes the link] http://aspyct.org/media/webmanner-bug.png But the shell below is older (open about 1 hour ago). Newer shells all print out &lt ;. So my first guess was that it somehow had a cached reference to the old inode of the file, or old blocks or whatever. So I modified parts of the script, at the start and then at the end, to print different messages. And, surprise, the message shown up on both terminals. But still, same difference between &lt ; and <. I'm confused... How to explain that behavior? I'm working on a OSX 10.8 (Mountain Lion) EDIT: OK, there is one big difference: the shell below uses ruby 1.9.3, while above is 1.8.7. Is there any known difference in string handling between the two versions ?

• Accessing CIFS shares from an OS X machine incredibly slow

  - by Aron Rotteveel

  This is a longshot, because this issue seems over-reported and unanswered on the internet (see references below), but it is about time this issue is permanently solved. The facts: Server: Windows Server 2008, acting as a file server Client: OS X Lion 10.7.3. Method of connecting: directly via IP through Finder: smb://192.168.1.100/share The problem: The initial connection attempt takes about a minute. After the connection is made, it takes one more minute to show the directories in Finder. After navigating to any other directory, it takes several seconds/minutes to parse the directory, seemingly based on the size of the contents. Actually, my entire Finder has this problem after connecting. When using Finder to show my desktop, it can literally take up to a minute to load. Obviously, this is not right. I have no clue how to fix this and would appreciate any help I can get. I am unsure about other relevant information I can provide, but if there is any, please let me know so I can update the post. I seem to be not the only one having this problem: Most importantly, an apple.stackexchange.com entry. Unsolved and unanswered. Several users on the Apple support forums. Users on EduGeek.

• Big Data&rsquo;s Killer App&hellip;

  - by jean-pierre.dijcks

  Recently Keith spent  some time talking about the cloud on this blog and I will spare you my thoughts on the whole thing. What I do want to write down is something about the Big Data movement and what I think is the killer app for Big Data... Where is this coming from, ok, I confess... I spent 3 days in cloud land at the Cloud Connect conference in Santa Clara and it was quite a lot of fun. One of the nice things at Cloud Connect was that there was a track dedicated to Big Data, which prompted me to some extend to write this post. What is Big Data anyways? The most valuable point made in the Big Data track was that Big Data in itself is not very cool. Doing something with Big Data is what makes all of this cool and interesting to a business user! The other good insight I got was that a lot of people think Big Data means a single gigantic monolithic system holding gazillions of bytes or documents or log files. Well turns out that most people in the Big Data track are talking about a lot of collections of smaller data sets. So rather than thinking "big = monolithic" you should be thinking "big = many data sets". This is more than just theoretical, it is actually relevant when thinking about big data and how to process it. It is important because it means that the platform that stores data will most likely consist out of multiple solutions. You may be storing logs on something like HDFS, you may store your customer information in Oracle and you may store distilled clickstream information in some distilled form in MySQL. The big question you will need to solve is not what lives where, but how to get it all together and get some value out of all that data. NoSQL and MapReduce Nope, sorry, this is not the killer app... and no I'm not saying this because my business card says Oracle and I'm therefore biased. I think language is important, but as with storage I think pragmatic is better. In other words, some questions can be answered with SQL very efficiently, others can be answered with PERL or TCL others with MR. History should teach us that anyone trying to solve a problem will use any and all tools around. For example, most data warehouses (Big Data 1.0?) get a lot of data in flat files. Everyone then runs a bunch of shell scripts to massage or verify those files and then shoves those files into the database. We've even built shell script support into external tables to allow for this. I think the Big Data projects will do the same. Some people will use MapReduce, although I would argue that things like Cascading are more interesting, some people will use Java. Some data is stored on HDFS making Cascading the way to go, some data is stored in Oracle and SQL does do a good job there. As with storage and with history, be pragmatic and use what fits and neither NoSQL nor MR will be the one and only. Also, a language, while important, does in itself not deliver business value. So while cool it is not a killer app... Vertical Behavioral Analytics This is the killer app! And you are now thinking: "what does that mean?" Let's decompose that heading. First of all, analytics. I would think you had guessed by now that this is really what I'm after, and of course you are right. But not just analytics, which has a very large scope and means many things to many people. I'm not just after Business Intelligence (analytics 1.0?) or data mining (analytics 2.0?) but I'm after something more interesting that you can only do after collecting large volumes of specific data. That all important data is about behavior. What do my customers do? More importantly why do they behave like that? If you can figure that out, you can tailor web sites, stores, products etc. to that behavior and figure out how to be successful. Today's behavior that is somewhat easily tracked is web site clicks, search patterns and all of those things that a web site or web server tracks. that is where the Big Data lives and where these patters are now emerging. Other examples however are emerging, and one of the examples used at the conference was about prediction churn for a telco based on the social network its members are a part of. That social network is not about LinkedIn or Facebook, but about who calls whom. I call you a lot, you switch provider, and I might/will switch too. And that just naturally brings me to the next word, vertical. Vertical in this context means per industry, e.g. communications or retail or government or any other vertical. The reason for being more specific than just behavioral analytics is that each industry has its own data sources, has its own quirky logic and has its own demands and priorities. Of course, the methods and some of the software will be common and some will have both retail and service industry analytics in place (your corner coffee store for example). But the gist of it all is that analytics that can predict customer behavior for a specific focused group of people in a specific industry is what makes Big Data interesting. Building a Vertical Behavioral Analysis System Well, that is going to be interesting. I have not seen much going on in that space and if I had to have some criticism on the cloud connect conference it would be the lack of concrete user cases on big data. The telco example, while a step into the vertical behavioral part is not really on big data. It used a sample of data from the customers' data warehouse. One thing I do think, and this is where I think parts of the NoSQL stuff come from, is that we will be doing this analysis where the data is. Over the past 10 years we at Oracle have called this in-database analytics. I guess we were (too) early? Now the entire market is going there including companies like SAS. In-place btw does not mean "no data movement at all", what it means that you will do this on data's permanent home. For SAS that is kind of the current problem. Most of the inputs live in a data warehouse. So why move it into SAS and back? That all worked with 1 TB data warehouses, but when we are looking at 100TB to 500 TB of distilled data... Comments? As it is still early days with these systems, I'm very interested in seeing reactions and thoughts to some of these thoughts...

• Windows Azure VMs - New "Stopped" VM Options Provide Cost-effective Flexibility for On-Demand Workloads

  - by KeithMayer

  Originally posted on: http://geekswithblogs.net/KeithMayer/archive/2013/06/22/windows-azure-vms---new-stopped-vm-options-provide-cost-effective.aspxDidn’t make it to TechEd this year? Don’t worry!  This month, we’ll be releasing a new article series that highlights the Best of TechEd announcements and technical information for IT Pros.  Today’s article focuses on a new, much-heralded enhancement to Windows Azure Infrastructure Services to make it more cost-effective for spinning VMs up and down on-demand on the Windows Azure cloud platform. NEW! VMs that are shutdown from the Windows Azure Management Portal will no longer continue to accumulate compute charges while stopped! Previous to this enhancement being available, the Azure platform maintained fabric resource reservations for VMs, even in a shutdown state, to ensure consistent resource availability when starting those VMs in the future.  And, this meant that VMs had to be exported and completely deprovisioned when not in use to avoid compute charges. In this article, I'll provide more details on the scenarios that this enhancement best fits, and I'll also review the new options and considerations that we now have for performing safe shutdowns of Windows Azure VMs. Which scenarios does the new enhancement best fit? Being able to easily shutdown VMs from the Windows Azure Management Portal without continued compute charges is a great enhancement for certain cloud use cases, such as: On-demand dev/test/lab environments - Freely start and stop lab VMs so that they are only accumulating compute charges when being actively used.  "Bursting" load-balanced web applications - Provision a number of load-balanced VMs, but keep the minimum number of VMs running to support "normal" loads. Easily start-up the remaining VMs only when needed to support peak loads. Disaster Recovery - Start-up "cold" VMs when needed to recover from disaster scenarios. BUT ... there is a consideration to keep in mind when using the Windows Azure Management Portal to shutdown VMs: although performing a VM shutdown via the Windows Azure Management Portal causes that VM to no longer accumulate compute charges, it also deallocates the VM from fabric resources to which it was previously assigned.  These fabric resources include compute resources such as virtual CPU cores and memory, as well as network resources, such as IP addresses.  This means that when the VM is later started after being shutdown from the portal, the VM could be assigned a different IP address or placed on a different compute node within the fabric. In some cases, you may want to shutdown VMs using the old approach, where fabric resource assignments are maintained while the VM is in a shutdown state.  Specifically, you may wish to do this when temporarily shutting down or restarting a "7x24" VM as part of a maintenance activity.  Good news - you can still revert back to the old VM shutdown behavior when necessary by using the alternate VM shutdown approaches listed below.  Let's walk through each approach for performing a VM Shutdown action on Windows Azure so that we can understand the benefits and considerations of each... How many ways can I shutdown a VM? In Windows Azure Infrastructure Services, there's three general ways that can be used to safely shutdown VMs: Shutdown VM via Windows Azure Management Portal Shutdown Guest Operating System inside the VM Stop VM via Windows PowerShell using Windows Azure PowerShell Module Although each of these options performs a safe shutdown of the guest operation system and the VM itself, each option handles the VM shutdown end state differently. Shutdown VM via Windows Azure Management Portal When clicking the Shutdown button at the bottom of the Virtual Machines page in the Windows Azure Management Portal, the VM is safely shutdown and "deallocated" from fabric resources.  Shutdown button on Virtual Machines page in Windows Azure Management Portal  When the shutdown process completes, the VM will be shown on the Virtual Machines page with a "Stopped ( Deallocated )" status as shown in the figure below. Virtual Machine in a "Stopped (Deallocated)" Status "Deallocated" means that the VM configuration is no longer being actively associated with fabric resources, such as virtual CPUs, memory and networks. In this state, the VM will not continue to allocate compute charges, but since fabric resources are deallocated, the VM could receive a different internal IP address ( called "Dynamic IPs" or "DIPs" in Windows Azure ) the next time it is started.  TIP: If you are leveraging this shutdown option and consistency of DIPs is important to applications running inside your VMs, you should consider using virtual networks with your VMs.  Virtual networks permit you to assign a specific IP Address Space for use with VMs that are assigned to that virtual network.  As long as you start VMs in the same order in which they were originally provisioned, each VM should be reassigned the same DIP that it was previously using. What about consistency of External IP Addresses? Great question! External IP addresses ( called "Virtual IPs" or "VIPs" in Windows Azure ) are associated with the cloud service in which one or more Windows Azure VMs are running.  As long as at least 1 VM inside a cloud service remains in a "Running" state, the VIP assigned to a cloud service will be preserved.  If all VMs inside a cloud service are in a "Stopped ( Deallocated )" status, then the cloud service may receive a different VIP when VMs are next restarted. TIP: If consistency of VIPs is important for the cloud services in which you are running VMs, consider keeping one VM inside each cloud service in the alternate VM shutdown state listed below to preserve the VIP associated with the cloud service. Shutdown Guest Operating System inside the VM When performing a Guest OS shutdown or restart ( ie., a shutdown or restart operation initiated from the Guest OS running inside the VM ), the VM configuration will not be deallocated from fabric resources. In the figure below, the VM has been shutdown from within the Guest OS and is shown with a "Stopped" VM status rather than the "Stopped ( Deallocated )" VM status that was shown in the previous figure. Note that it may require a few minutes for the Windows Azure Management Portal to reflect that the VM is in a "Stopped" state in this scenario, because we are performing an OS shutdown inside the VM rather than through an Azure management endpoint. Virtual Machine in a "Stopped" Status VMs shown in a "Stopped" status will continue to accumulate compute charges, because fabric resources are still being reserved for these VMs.  However, this also means that DIPs and VIPs are preserved for VMs in this state, so you don't have to worry about VMs and cloud services getting different IP addresses when they are started in the future. Stop VM via Windows PowerShell In the latest version of the Windows Azure PowerShell Module, a new -StayProvisioned parameter has been added to the Stop-AzureVM cmdlet. This new parameter provides the flexibility to choose the VM configuration end result when stopping VMs using PowerShell: When running the Stop-AzureVM cmdlet without the -StayProvisioned parameter specified, the VM will be safely stopped and deallocated; that is, the VM will be left in a "Stopped ( Deallocated )" status just like the end result when a VM Shutdown operation is performed via the Windows Azure Management Portal.  When running the Stop-AzureVM cmdlet with the -StayProvisioned parameter specified, the VM will be safely stopped but fabric resource reservations will be preserved; that is the VM will be left in a "Stopped" status just like the end result when performing a Guest OS shutdown operation. So, with PowerShell, you can choose how Windows Azure should handle VM configuration and fabric resource reservations when stopping VMs on a case-by-case basis. TIP: It's important to note that the -StayProvisioned parameter is only available in the latest version of the Windows Azure PowerShell Module.  So, if you've previously downloaded this module, be sure to download and install the latest version to get this new functionality.

• XCode Build Parse Error 'Unexpected @ in Program'

  - by Grymjack

  I'm following a tutorial for creating an animation using Xcode Version 4.5.2 in Mountain Lion 10.8.2. When trying to build the code below, I get a Parse Error Unexpected '@' in program showing up for the 'hopAnimation=' line. While searching, I have found examples that build simple animations in a different way, but nothing that seems to address this particular problem. I'm a noob to XCode programming and if anyone could help me correct the syntax, I would highly appreciate it. I would also like to thank all the contributors to stackflow for making this such a valuable resource. Searching for the answers to most of my prior questions always seemed to have you guys at the top of the results list. ViewController.m - (void)viewDidLoad { // load all the frames of our animation into an array NSArray *hopAnimation; hopAnimation=[[NSArray alloc] arrayWithObjects: [UIImage imageNamed:@”frame-1.png”], [UIImage imageNamed:@”frame-2.png”], [UIImage imageNamed:@”frame-3.png”], [UIImage imageNamed:@”frame-4.png”], [UIImage imageNamed:@”frame-5.png”], [UIImage imageNamed:@”frame-6.png”], [UIImage imageNamed:@”frame-7.png”], [UIImage imageNamed:@”frame-8.png”], [UIImage imageNamed:@”frame-9.png”], [UIImage imageNamed:@”frame-10.png”], [UIImage imageNamed:@”frame-11.png”], [UIImage imageNamed:@”frame-12.png”], [UIImage imageNamed:@”frame-13.png”], [UIImage imageNamed:@”frame-14.png”], [UIImage imageNamed:@”frame-15.png”], [UIImage imageNamed:@”frame-16.png”], [UIImage imageNamed:@”frame-17.png”], [UIImage imageNamed:@”frame-18.png”], [UIImage imageNamed:@”frame-19.png”], [UIImage imageNamed:@”frame-20.png”],nil]; self.bunnyView1.animationImages=hopAnimation; self.bunnyView2.animationImages=hopAnimation; self.bunnyView3.animationImages=hopAnimation; self.bunnyView4.animationImages=hopAnimation; self.bunnyView5.animationImages=hopAnimation; self.bunnyView1.animationDuration=1; self.bunnyView2.animationDuration=1; self.bunnyView3.animationDuration=1; self.bunnyView4.animationDuration=1; self.bunnyView5.animationDuration=1; [super viewDidLoad]; }

• Automatically grow document view of NSScrollView using auto layout?

  - by Monolo

  Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)? I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results. fittingSize of the document view reports the correct size. An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout. Edited to clarify: The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method. What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly. NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).
