• Should I install an AV product on my domain controllers?

  - by mhud

  Should I run a server-specific antivirus, regular antivirus, or no antivirus at all on my servers, particularly my Domain Controllers? Here's some background about why I'm asking this question: I've never questioned that antivirus software should be running on all windows machines, period. Lately I've had some obscure Active Directory related issues that I have tracked down to antivirus software running on our domain controllers. The specific issue was that Symantec Endpoint Protection was running on all domain controllers. Occasionally, our Exchange server triggered a false-positive in Symantec's "Network Threat Protection" on each DC in sequence. After exhausting access to all DCs, Exchange began refusing requests, presumably because it could not communicate with any Global Catalog servers or perform any authentication. Outages would last about ten minutes at a time, and would occur once every few days. It took a long time to isolate the problem because it was not easily reproducible and generally investigation was done after the issue resolved itself.

• cd ~ dumps me in a seemingly empty directory

  - by Davidos

  This is on a Linux mint box. I'm told everywhere to use the command cd ~ To switch to the root directory before doing some command line magic. For some reason though, it dumps me in a directory named ~ where ls gives nothing and I can't get back to my home directory; I have to restart the terminal session to get out of the empty root directory. I'm positive that everything is just hidden to me, but even as a super-user I can't get the folders to show themselves. I usually just fall back to using a graphical file browser to roam those forbidden files, but I've recently just been shut out of my root directory, and the machine refuses to allow me to change the permissions on the stupid thing even when I type the root password in. It may just be some over-rigorous end-user shielding on the part of the mint team, but it's getting to be really frustrating now.

• Linux virtualized screen resolution

  - by vladev

  Hopefully there is a positive answer to this question: I have a 15.4" laptop with native screen resolution of 1920x1200. You can imagine that everything is completely unreadable by default. If I increase the font size it becomes readable, but ugly. Is it possible to set the "real" resolution to 1920x1200 so it plays nice with the monitor, but set some "virtual" resolution of 1440x900 so that everything starts looking nice. Note: If I just change the resolution to 1440x900 everything becomes blurry, since this is not the monitor's default resolution. I know that having a small monitor with high resolution is not very optimal - not my choice. (Using nvidia GF8400M)

• Windows 8 Update on Bootcamp

  - by RazorSharp

  I currently have Windows 8 Consumer Preview installed on a Mac Bootcamp Partition. Microsoft recently released the Windows 8 Release Preview, and I'd like to upgrade, but I'm worried that upgrading to the Release Preview (while in the Windows 8 partition) will erase my other partitions (ex. the Mac OS X partition). By upgrading from Consumer to Release (using the installer on Microsoft's website) while IN the Windows 8 partition, will it end up re-formating the whole hard drive / erasing partitions / removing Mac OS X? Are there any 100% positive answers out there? Will this work, and if not then how would you suggest updating? Note: I have a Time Machine backup of my Mac, but it isn't the WHOLE Mac.

• DSP - Problems using the inverse Fast Fourier Transform

  - by Trap

  I've been playing around a little with the Exocortex implementation of the FFT, but I'm having some problems. First, after calculating the inverse FFT of an unchanged frequency spectrum obtained by a previous forward FFT, one would expect to get the original signal back, but this is not the case. I had to figure out that I needed to scale the FFT output to about 1 / fftLength to get the amplitudes ok. Why is this? Second, whenever I modify the amplitudes of the frequency bins before calling the iFFT the signal gets distorted at low frequencies. However, this does not happen if I attenuate all the bins by the same factor. Let me put a very simplified example of the output buffer of a 4-sample FFT: // Bin 0 (DC) FFTOut[0] = 0.0000610351563 FFTOut[1] = 0.0 // Bin 1 FFTOut[2] = 0.000331878662 FFTOut[3] = 0.000629425049 // Central bin FFTOut[4] = -0.0000381469727 FFTOut[5] = 0.0 // Bin 3, this is a negative frequency bin. FFTOut[6] = 0.000331878662 FFTOut[7] = -0.000629425049 The output is composed of pairs of floats, each representing the real and imaginay parts of a single bin. So, bin 0 (array indexes 0, 1) would represent the real and imaginary parts of the DC frequency. As you can see, bins 1 and 3 both have the same values, (except for the sign of the Im part), so I guess these are the negative frequency values, and finally indexes (4, 5) would be the central frequency bin. To attenuate the frequency bin 1 this is what I do: // Attenuate the 'positive' bin FFTOut[2] *= 0.5; FFTOut[3] *= 0.5; // Attenuate its corresponding negative bin. FFTOut[6] *= 0.5; FFTOut[7] *= 0.5; For the actual tests I'm using a 1024-length FFT and I always provide all the samples so no 0-padding is needed. // Attenuate var halfSize = fftWindowLength / 2; float leftFreq = 0f; float rightFreq = 22050f; for( var c = 1; c < halfSize; c++ ) { var freq = c * (44100d / halfSize); // Calc. positive and negative frequency locations. var k = c * 2; var nk = (fftWindowLength - c) * 2; // This kind of attenuation corresponds to a high-pass filter. // The attenuation at the transition band is linearly applied, could // this be the cause of the distortion of low frequencies? var attn = (freq < leftFreq) ? 0 : (freq < rightFreq) ? ((freq - leftFreq) / (rightFreq - leftFreq)) : 1; mFFTOut[ k ] *= (float)attn; mFFTOut[ k + 1 ] *= (float)attn; mFFTOut[ nk ] *= (float)attn; mFFTOut[ nk + 1 ] *= (float)attn; } Obviously I'm doing something wrong but can't figure out what or where.

• Microsoft launches IE9 preview – No support for XP

  - by samsudeen

  Microsoft launched the developer preview version of Internet Explorer 9 (IE9) at MIX 10 web conference yesterday.This release is aimed getting the feedback from website designers , developers and other community to make IE9 development better from its previous versions. Microsoft will update the developer preview every eight weeks and the next update is expected on mid of march.So what is new and interesting  about IE9 Chakra Chakra (The new scripting engine of IE9) renders the Java script much faster compared to IE8 and other browsers thus improving the performance significantly.According to Microsoft Chakra renders the java script in background with a separate thread parallel to the main engine which is complete new way of rendering from the current browser technologies Standards Microsoft is desperate to make ( surprisingly!!!) IE9 compliance to  web standards by supporting the open standards such as Accelerated support for HTML5 video support for new web technologies such as CSS3 and SVG2. ACID3 Test IE9 scores (55/100) in its latest ACID3 test which is much better compared to the IE8 score (22/100) but not even  nearer to their rivals Chrome, Opera, and Safari which scores 100/100 in ACID3 testing I am little disappointed over not able to download the  developer preview on my XP machine. The early comments looks much positive for IE9.If you want to explore IE9,check the Microsoft Test drive site  at Microsoft IE9 Test-drive You can also download the IE9 developer preview at Download Preview Join us on Facebook to read all our stories right inside your Facebook news feed.

• The Disloyalty Card

  - by David Dorf

  Let's take a break from technology for a second; please indulge me. (That's for you Erick.) A few months back, James Hoffmann reported that Gwilym Davies, the 2009 World Barista Champion, had implemented a rather unique idea for his cafe: the disloyalty card. His card lists eight nearby cafes in London that the cardholder must visit and try a coffee. After sampling all eight and collecting the required stamps, Gwilym provides a free coffee from his shop. His idea sends customers to his competitors. What does this say about Gwilym? First, it tells me he's confident in his abilities to make a mean cup of java. Second, it tells me he's truly passionate about his his trade. But was this a sound business endeavor? Obviously the risk is that one of his loyal customers might just find a better product at a competitor and not return. But the goal isn't really to strengthen his customer base -- its to strengthen the market, which will in turn provide more customers over the long run. This idea seems great for frequently purchased products like restaurants, bars, bakeries, music, and of course, cafes. Its probably not a good idea for high priced merchandise or infrequently purchased items like shoes, electronics, and housewares. Nevertheless, its a great example of thinking in reverse. Try this: Instead of telling your staff how you want customers treated, list out the ways you don't want customers treated. Why should you limit people's imagination and freedom to engage customers? Instead, give them guidelines to avoid the bad behavior, and leave them open to be creative with the positive behavior. Instead of asking the question, "how can we get more people in our stores?" try asking the inverse: "why aren't people visiting our stores?" Innovation doesn't only come from asking "why?" Often it comes from asking "why not?"

• Work Item Visualizer for TFS 2010 - New Extension

  - by MikeParks

  I released another new extension to the Visual Studio Gallery again today called Work Item Visualizer for TFS 2010. I've only heard positive things about it so far, hopefully it stays that way :) Basically, it creates a diagram of all work items linked to a work item ID which the user specifies in a search box. This extension was coded using DGML (the same graph rendering language used for the Visual Studio 2010 Architecture Tools). It was pretty cool getting a chance to create something using some of the newest technology out there. Well, I just wanted to throw a blog up to get the word out on it a little more. If you're using Visual Studio 2010 with Team Foundation Server 2010, feel free to check it out! Thanks everyone. Download Link: http://visualstudiogallery.msdn.microsoft.com/en-us/a35b6010-750b-47f6-a7a5-41f0fa7294d2   What it does: ·         Creates a DGML graph to visualize linked TFS Work Items by entering a Work Item ID in the toolbar search box   How it benefits you: ·         Allows you to easily analyze the hierarchy of your TFS Work Items ·         Gain the ability to perform basic risk/impact analysis when creating or editing Work Items ·         Great for meetings in the case that you need to discuss the entire scope of linked Work Items ·         Easier project planning ·         Eliminates the need to create TFS queries or reports to view tree of Work Items ·         Easily lets you see the entire tree of work items linked to the one you’re working on   Navigation Tips: ·         Use Ctrl + Mouse Wheel Scroll to zoom in and out ·         Use Ctrl + Left Mouse click (and hold) to move document around ·         Right click on DGML area for more options (Like copy image or viewing in groups) ·         Clicking on each node highlights that node and the links connected to it ·         Colors in the legend can be changed ·         When work item nodes are deleted, the view is automatically updated ·         Double clicking on work item node will open up the Work Items URL   Try it out on work items that have several of links and let us know what you think. A big thanks goes out to everyone working on the http://visualization.codeplex.com/ project for publishing the source code on CodePlex which really helped me learn how DGML (Directed Graph Markup Language - New to Visual Studio 2010 Architecture Tools) works!    - Mike

• Why / how does XNA's right-handed coordinate system effect anything if you can specify near/far Z values?

  - by vargonian

  I am told repeatedly that XNA Game Studio uses a right-handed coordinate system, and I understand the difference between a right-handed and left-handed coordinate system. But given that you can use a method like Matrix.CreateOrthographicOffCenter to create your own custom projection matrix, specifying the left, right, top, bottom, zNear and zFar values, when does XNA's coordinate system come into play? For example, I'm told that in a right-handed coordinate system, increasingly negative Z values go "into" the screen. But I can easily create my projection matrix like this: Matrix.CreateOrthographicOffCenter(left, right, bottom, top, 0.1f, 10000f); I've now specified a lower value for the near Z than the far Z, which, as I understand it, means that positive Z now goes into the screen. I can similarly tweak the values of left/right/top/bottom to achieve similar results. If specifying a lower zNear than zFar value doesn't affect the Z direction of the coordinate system, what does it do? And when is the right-handed coordinate system enforced? The reason I ask is that I'm trying to implement a 2.5D camera that supports zooming and rotation, and I've spent two full days encountering one unexpected result after another.

• What design patters are the worst or most narrowly defined?

  - by Akku

  For every programming project, Managers with past programming experience try to shine when they recommend some design patterns for your project. I like design patterns when they make sense or if you need a scalbale solution. I've used Proxies, Observers and Command patterns in a positive way for example, and do so every day. But I'm really hesitant to use say a Factory pattern if there's only one way to create an object, as a factory might make it all easier in the future, but complicates the code and is pure overhead. So, my question is in respect to my future career and my answer to manager types throwing random pattern-names around: Which design patterns did you use, that threw you back overall? Which are the worst design patterns, that you shouldn't have a look at if it's not that only single situation where it makes sense (read: which design patterns are very narrowly defined)? (It's like I was looking for the negative reviews of an overall good product of amazon to see what bugged people most in using design patterns). And I'm not talking about Anti-Patterns here, but about Patterns that are usually thought of as "good" patterns.

• Elevating Customer Experience through Enterprise Social Networking

  - by john.brunswick

  I am not sure about most people, but I really dislike automated call center routing systems. They are impersonal and convey a sense that the company I am dealing with does not see the value of providing customer service that increases positive perception of their brand. By the time I am connected with a live support representative I am actually more frustrated than before I originally dialed. Each time a company interacts with its customers or prospects there is an opportunity to enhance that relationship. Technical enablers like call center routing systems can be a double edged sword - providing process efficiencies, but removing the human context of some interactions that can build a lot of long term value and create substantial repeat business. Certain web systems, available through "chat with a representative" now links on some web sites, provide a quick and easy way to get in touch with someone and cut down on help desk calls, but miss the opportunity to deliver an even more personal experience to customers and prospects. As more and more users head to the web for self-service and product information, the quality of this interaction becomes critical to supporting a company's brand image and viability. It takes very little effort to go a step further and elevate customer experience, without adding significant cost through social enterprise software technologies. Enterprise Social Networking Social networking technologies have slowly gained footholds in the enterprise, evolving from something that people may have been simply curious about, to tools that have started to provide tangible value in the enterprise. Much like instant messaging, once considered a toy in the enterprise, expertise search, blogs as communications tools, wikis for tacit knowledge sharing are all seeing adoption in a way that is directly applicable to the business and quickly adding value. So where does social networking come in when trying to enhance customer experience?

• SQL SERVER- Differences Between Left Join and Left Outer Join

  - by pinaldave

  There are a few questions that I had decided not to discuss on this blog because I think they are very simple and many of us know it. Many times, I even receive not-so positive notes from several readers when I am writing something simple. However, assuming that we know all and beginners should know everything is not the right attitude. Since day 1, I have been keeping a small journal regarding questions that I receive in this blog. There are around 200+ questions I receive every day through emails, comments and occasional phone calls. Yesterday, I received a comment with the following question: What are the differences between Left Join and Left Outer Join? Click here to read original comment. This question has triggered the threshold of receiving the same question repeatedly. Here is the answer: There is absolutely no difference between LEFT JOIN and LEFT OUTER JOIN. The same is true for RIGHT JOIN and RIGHT OUTER JOIN. When you use LEFT JOIN keyword in SQL Server, it means LEFT OUTER JOIN only. I have already written in-depth visual diagram discussing the JOINs. I encourage all of you to read the article for further understanding of the JOINs: Read Introduction to JOINs – Basic of JOINs Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, PostADay, SQL, SQL Authority, SQL Joins, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Rouen Business School builds its entire back office UI with Visual WebGui

  - by Webgui

  Two years ago, Rouen Business School (AMBA accredited institution located in Rouen, Normandy, France) decided to develop and implement a proprietary information system in-house. The objective was to administer all the data encompassed by a classic 3500 Students business school: from on-line application forms to the registration system including financial information, scheduling, grades management, etc. The development team at Rouen Business School chose Visual WebGui for the UI. “When we tested the Visual WebGui solution we were really amazed and enthusiastic. It was exactly the kind of solution we were looking for… The great performance of the solution allows us to manage a large amount of information with no delay with a very positive feedback at the user end,” said Stéphane Henry the IT Project Manager of the school.   As a result of the fast development, easy deployment, performance, and professional design that the team experienced with Visual WebGui, the entire back office of Rouen Business School information system was chosen to be developed with the Visual WebGui framework “and after two years we do not see any reason to change this,” commented Stéphane Henry who added that “all the original requirements were satisfied using Visual WebGui.” You can read the full Case study here >

• Caching in the .NET Stack: Inside-Out

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/06/28/caching-in-the-.net-stack-inside-out.aspxI'm delighted to have my first course published on Pluralsight - Caching in the .NET Stack: Inside-out.   It's a pretty comprehensive look at caching in .NET solutions. The first half covers using local, remote and persistent cache stores inside the solution, including the .NET MemoryCache, NCache Express, AppFabric Caching, memcached, Azure Table Storage and local disk stores. The second half covers caching outside the solution in HTTP clients and proxies, and how to set up ASP.NET WebForms, MVC, Web API and WCF projects to use HTTP validation and expiration caching.   The course takes a hands-on approach, starting with a distributed solution that has no caching, analysing key points which can benefit from caching, and adding different types of cache. At the end of the course I run through a set of before and after performance tests, stressing the solution under load. Without caching and with 60 concurrent users the page response time maxes out at 18 seconds - with caching that falls to 2 seconds, so it's a huge improvement from very little effort. I’d be glad to hear feedback if you watch the course, especially if it’s as positive as my editor’s.

• Has "Killer Game Programming in Java" by Andrew Davison been rendered useless? What new tutorial should I follow? [duplicate]

  - by BDillan

  This question already has an answer here: Killer Game Programming [Java 3D] outdated? 5 answers Its pathetic how it was created in 2005 not so long ago when the Java 3D 1.31 API was released. Now after downloading the source code off the books website and implementing it onto my work-space it cant run. (The 3D Shooter Ch. 23) I downloaded Java 3D 1.5 API, installed it- went back to my source code and javax.media ect.., and EVERY imported class within the game simply couldn't be resolved... they are all outdated.. Please do not say how its meant for a positive curvature in your game development skills. No ~ I got the book to understand how to code 3D textures/particle systems/games. Without seeing results how can I learn? If there is still hope for this book please tell me. Otherwise what other books match this one in Game Programming? This one was very well organized, documented and long. I am not looking for a 3D game prog. book on Java. Rather one that has the same reputation as this one but is a bit newer..

• It&rsquo;s About You: Tell Microsoft How They&rsquo;re Doing!

  - by juanlarios

  Every fall and spring, a survey goes out to a few hundred thousand IT folk in Canada asking what they think of Microsoft as a company. The information they get from this survey helps them understand what problems and issues you’re facing and how they can do better. The team at Microsoft Canada takes the input they get from this survey very seriously. Now I don’t know who of you will get the survey and who won’t but if you do find an email in your inbox from "Microsoft Feedback” with an email address of “ [email protected] ” and a subject line “Help Microsoft Focus on Customers and Partners” from now until April 13th — it’s not a hoax or phishing email. Please open it and take a few minutes to tell them what you think. This is your chance to get your voice heard: If they’re doing well, feel free to pile on the kudos (they love positive feedback!) and if you see areas they can improve, please point them out so they can make adjustments (they also love constructive criticism!). The Microsoft team would like to thank you for all your feedback in the past — to those of you who have filled out the survey and sent them emails. Thank you to all who engage with them in so many different ways through events, the blogs, online and in person. You are why they do what they do and they feel lucky to work with such a great community! One last thing - even if you don’t get the survey you can always give the team feedback by emailing us directly through the Microsoft Canada IT Pro Feedback email address . They want to make sure they are serving you in the best possible way. Tell them what you want more of. What should they do less of or stop altogether? How can they help? Do you want more cowbell ? Let them know through the survey or the email alias. They love hearing from you!

• Receiving an MVP Award and Credibility

  - by Joe Mayo

  The post titled, The Problem with MVPs, by Steve Barbour was interesting because it makes you think about the thousands of MVPs around the world and what their value really is. Having been the recipient of multiple MVP awards, it’s an opportunity to reflect and judge my own performance. This is not a dangerous thing to do, but quite the opposite. If a person believes in self improvement, then critical analysis is an important part of that process. A lot of MVPs will tell you that they would be doing the same thing, regardless of whether they were an MVP or not; helping others in the community, which is also where I prefer to hang my hat. I’ve never defined myself as an expert and never will; this determination is left to others. In fact, let me just come out and say it, “I don’t know everything”. Shocked? Sometimes the gap between expectations and reality extends beyond a reasonable measure. Being labeled as a technical expert feels good for one's self esteem and is certainly a useful motivational technique. A problem can emerge though when an individual believes, too much, in what they are told. The problem is not with a pat on the back, but with a person does with the positive reinforcement. Is narcissism too strong a word? How often have you been in a public forum reading a demeaning response to a question that only serves in attempt to raise the stature of the person providing the response? Such behavior compromises one’s credibility, raises questions about validity of the MVP award, and is limited in community value. I’m currently under consideration for another MVP award on April 1st. If it happens, it will be good. Otherwise, I’ll keep writing articles, coding open source software, and whatever else I enjoy doing; with the best reward being that people find value in what I do.

• Revamped Google Webmaster Tools

  With a positive surprise I realized today that Google's Webmaster Tools had some minor overhauling and provide some more details than before. Most obvious are the changes on the dashboard where the Top Search Queries now provide information about impressions and clicktroughs instead of the rankings before. Only the links of the search expressions are missing. It seems that the Top search queries were in the focus of this update. The section is now spiced with detailed graphs about what happened during selectable periods on your site. Well, seems that the Webmaster Tools mimic a stripped-down version of Google Analytics... I was very pleased by the details that are offered when you click on a single query term. Really nice to see the search rankings and your responsible URLs at the same time. Before, you had to put two browser instances side-by-side to achieve this kind of overview. Personally, I like the approach to visualize statistics the way Google or other providers do. It gives you a quick and informative overview, and enables you to dig further into details about peaks and lows on your visits, page impressions or clickthroughs.

• Ubuntu eats itself after I followed updater instruction

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I (and this is from noob memory) sudo apt-get install -f. I did this and typed in the confirmation phrase and watched apt-get systematically remove every component of linux, both the stuff I installed and the core ubuntu packages. I could only assume at this stage that this was for a fresh install but of course, I know better now. There's much complaint about Windows, but I've never met with advice from Microsoft tools to wipe out the operating system because of a couple of missing .dlls. So what gives? This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. I'm tempted, but I have hopes of recovering the data that I had enough misguided faith to trust to the linux ext4 partition. I've tried pen driving back into it with a 32 bit iso but I'm simply informed that ubuntu is running in low graphics mode and get to watch the dots cycle indefinitely. EDIT: Thanks for the advice vis positive request. I've got onto the machine with a 64 bit stick and can see the file structure left behind by the installation. My first instinct was to run install from the stick but it did not seem to offer a recovery option. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings. I'm particularly worried about losing email from evolution - the rest I could probably lash back together. I would also be interested how this disaster came about. I see people in the know recommending this same procedure in similar circumstances. Thanks for your attention, Tony Martin

• "Give with Bing" - Help raise money for Sports relief while searching for whatever you want

  - by Testas

  While Sport Relief drives fundraising by challenging people to do physical activities such as running a mile, we’re introducing the ‘Bing Search Mile,’ which gives people the ability to search using Bing and raise money for charity. For every 10 searches made, Bing.com will donate 5p to Sport Relief 2010, enabling you, and your friends and family, to raise money just by searching with Bing until the end of March. With the average mile taking about 10 minutes to run, in the same time, you can make up to 150 searches online - that’s 75p raised for a good cause per ‘search mile’. And while you’re at it,  why not step it up a gear and aim to complete a ‘Search Mile’ each day or even a ‘Search Marathon’ over the 5 week campaign with your colleagues, friends and family? How to get involved: 1.      Visit GiveWithBing.com and download the Official Sport Relief Bing Counter. Once downloaded, the Sport Relief counter will count all the searches you do on Bing from that point on.  2.      Now that you’re registered (and signed in), invite your friends, family, colleagues or classmates to join in the fundraising with you – GiveWithBing.com automatically generates an email explaining how it works for you to send them – the more people who search with you, the more money you raise. People can also register a school 3.      Run your ‘search mile’ every day and watch how your searches turn into life-changing cash for charity, with every 10 searches equalling 5p for Sport Relief. You can check your progress by visiting your individual page (more info here).  This is such a positive initiative and I challenge everyone in the UK to invite their key contacts to be part of Give with Bing.   Chris

• MySQL Connect Conference: My Experience

  - by Hema Sridharan

  It was a great experience to attend the MySQL Connect Conference for the first time ever. Personally I was very much enthralled to present about "How to make MySQL Backups" besides attending different sessions to absorb more knowledge about the technical prospects of MySQL. One of the agenda items in my presentation was "MySQL Enterprise Backup" functionality and features. There were total of 40 attendees in the session, who were very much interested about the MySQL Enterprise Backup product and gave positive feedback as well as areas of improvements on our product. Some of our features brought lot of excitement and smile amongst our customers including,1. Performance improvements in MEB 3.8.02. Incremental Base option from MEB 3.7.1 where there is no need to specify the directory name of the previous backup to fetch the lsn values and instead can directly fetch from backup_history table using --incremental-base=history: last_backup3. only-innodb-with-frm option introduced in MEB 3.7 version. A true online hot backup of InnoDB tables.I also attended a session with similar topic "MEB Best Practices" conducted by Sanjay Manwani, where he double clicked all the features and best strategies of backup & restore. I also got an opportunity to attend other sessions including,* Enabling the new generation of web and cloud services with MySQL 5.6 replication* Getting the most out of MySQL with MySQL Workbench* InnoDB compression for OLTP* Scaling for the Web and Cloud with MySQL replication.Above all, had some special moments in the conference including meeting some of the executives / colleagues for the first time f2f. On a whole, the first MySQL Connect conference was a great success in terms of manifesting the features of our products, direct feedback from customer and team building.  We also had some applauding yahoo moments when Tomas Ulin announced different releases including MySQL 5.6 RC, Connector Python 1.0 and ODBC 5.2 release, MySQL Cluster 7.3, additions to MySQL Enterprise edition etc.

• LastPass Now Monitors Your Accounts for Security Breaches

  - by Jason Fitzpatrick

  Staying on top of security breaches and how they may or may not affect you is time consuming. Sentry, a new and free addition to the LastPass password management tool, automates the process and notifies you of breaches. In response to all the recent and unfortunate high-profile security breaches LastPass has rolled out Sentry–a tool that monitors breach lists to notify you if your email appears in a list of breached accounts. The lists are supplied by PwnedList, a massive database of security breach data, and securely indexed against your accounts within the LastPass system. If there is a security breach and your email is on the list, you’ll receive an automated email notice indicating which website was compromised and that your email address was one of the positive matches from the breach list. LastPass Sentry is a free feature and, as of yesterday, is automatically activated on all Free, Premium, and Enterprise level accounts. Hit up the link below to read the official announcement.

• One eye on my dinner and one eye on SQL server

  - by fatherjack

  LiveJournal Tags: RedGate,Work Life Balance,Tips and Tricks,SQL Server This is somewhere between a Tweet and a proper blog article - would that be a Bleet? Anyway, I was at a local restaurant yesterday and after placing my order I was thinking about having to get home and log in to check some SQL Servers and then the thought came to me that as we were near civilisation there was likely to be a 3G signal that might actually make using the web browser on my phone bearable. It was surprisingly fast on my HTC Desire, it was almost as good as Wi-Fi. RedGate SQL Monitor works fine on the default HTC browser and here is the proof, me checking the servers while I am waiting for the meal to arrive. Everything checked out OK so I had the evening free from SQL Server. You can get a free 14 day full trial of a SQL Monitor from RedGate here or find out more about it at The Future of Monitoring. Disclosure: I am a friend of RedGate and as such regularly make positive comments about their products. I don't get paid for it but I do get free licenses for testing and reviewing purposes.
