• Big Data – Interacting with Hadoop – What is Sqoop? – What is Zookeeper? – Day 17 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the Pig and Pig Latin in Big Data Story. In this article we will understand what is Sqoop and Zookeeper in Big Data Story. There are two most important components one should learn when learning about interacting with Hadoop – Sqoop and Zookper. What is Sqoop? Most of the business stores their data in RDBMS as well as other data warehouse solutions. They need a way to move data to the Hadoop system to do various processing and return it back to RDBMS from Hadoop system. The data movement can happen in real time or at various intervals in bulk. We need a tool which can help us move this data from SQL to Hadoop and from Hadoop to SQL. Sqoop (SQL to Hadoop) is such a tool which extract data from non-Hadoop data sources and transform them into the format which Hadoop can use it and later it loads them into HDFS. Essentially it is ETL tool where it Extracts, Transform and Load from SQL to Hadoop. The best part is that it also does extract data from Hadoop and loads them to Non-SQL (or RDBMS) data stores. Essentially, Sqoop is a command line tool which does SQL to Hadoop and Hadoop to SQL. It is a command line interpreter. It creates MapReduce job behinds the scene to import data from an external database to HDFS. It is very effective and easy to learn tool for nonprogrammers. What is Zookeeper? ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. In other words Zookeeper is a replicated synchronization service with eventual consistency. In simpler words – in Hadoop cluster there are many different nodes and one node is master. Let us assume that master node fails due to any reason. In this case, the role of the master node has to be transferred to a different node. The main role of the master node is managing the writers as that task requires persistence in order of writing. In this kind of scenario Zookeeper will assign new master node and make sure that Hadoop cluster performs without any glitch. Zookeeper is the Hadoop’s method of coordinating all the elements of these distributed systems. Here are few of the tasks which Zookeepr is responsible for. Zookeeper manages the entire workflow of starting and stopping various nodes in the Hadoop’s cluster. In Hadoop cluster when any processes need certain configuration to complete the task. Zookeeper makes sure that certain node gets necessary configuration consistently. In case of the master node fails, Zookeepr can assign new master node and make sure cluster works as expected. There many other tasks Zookeeper performance when it is about Hadoop cluster and communication. Basically without the help of Zookeeper it is not possible to design any new fault tolerant distributed application. Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Big Data Analytics.

• Three Buckets of Knowledge

  - by BuckWoody

  As I learn more and more about SQL Server every day, I divide up my information into three “buckets”: Concepts In the first bucket are the general concepts about the topic. What is it? What does it do (or sometimes, what is is supposed to do?) How does one operation flow to another? For this information I use books, magazine articles and believe it or not – Wikipedia. I don’t always trust that last source, but I do use it to see how others lay out their thoughts around a concept. I really like graphical charts that show me the process flow if I can get it, and this is an ideal place for a good presentation. In fact, this may be the only real use for a presentation – I’ll explain what I mean in a moment. Reference The references for a topic include things like Transact-SQL (T-SQL) syntax, or the screen layout on a panel, things like that. Think Dictionary. The only reference I trust for this information is Books Online – presentations are fine, but we’re talking about a dictionary. Ever go to a movie that just reads through a dictionary? Me neither. But I have gone to presentations where people try to include tons of reference materials in their slides. Even if you give me the presentation material later, it’s not really a searchable, readable medium. How To A how-to for me is an example, or even better, a tutorial about an example. Whatever it is shows me a practical use for the concepts and of course involves the syntax. The important thing here is that you need to be able to separate out the example the person is showing you from the stuff you need to know. I can’t tell you how many times folks have told me, “well, sure, if yours is red then that works. But mine is blue.” And I have to explain, “then use “blue” for the search word here.” You get the idea. No one will do your work for you – the examples are meant as a teaching tool only. I accept that, learn what I can, and then run off to create my own thing. You might think a How To works well in a presentation, and it does, for the most part. For a complex example or tutorial, I still prefer the printed word (electronic if possible) so that I can go over the example multiple times, skip around and so on.   The order here isn’t actually that important. Most of the time I start with a concept, look at an example, and then read the reference material. But sometimes I look up an example, read a little of concepts and then check the reference. The only primary thing I try to enforce is to read something from each of them. It’s dangerous to base your work on any single example, reference or concept.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Rolling Along: PASS Board Year 2, Q2

  - by Denise McInerney

  Eighteen months into my time as a PASS Director I’m especially proud of what the Virtual Chapters have accomplished and want to share that progress with you. I'm also pleased that the organization has invested more resources to support the VCs. In this quarter I got to attend two conferences and meet more members of the SQL community. Virtual Chapters In the first six months of 2013 VCs have hosted more than 50 webinars, offering free technical education to over 6200 attendees. This is a great benefit to PASS members; thanks to the VC leaders, volunteers and speakers who contribute their time to produce these events. The Performance VC held their “Summer Performance Palooza”, an event featuring eight back-to-back sessions. Links to the session recordings can be found on the VCs web site. The new webinar platform, GoToWebinar, has been rolled out to all the VCs. This is a more stable, scalable platform and represents an important investment into the future of the VCs. A few new VCs are in the planning stages, including one focused on Security and one for Russian speakers. Visit the Virtual Chapter home page to sign up for the chapters that interest you. Each Virtual Chapter is offering a discount code for PASS Summit 2013. Be sure to ask your VC leader for the code to save $200 on Summit registration. 24 Hours of PASS The next 24HOP will be on July 31. This Summit Preview edition will feature 24 consecutive webcasts presented by experts who will be speaking at Summit in October. Registration for this free event is open now. And we will be using the GoToWebinar platform for 24HOP also. Business Analytics Conference April marked the first PASS Business Analytics Conference in Chicago. This introduced PASS to another segment of data professionals: the analysts and data scientists who work with the world’s growing collection of data. Overall the inaugural event was a success and gave us a glimpse into this increasingly important space. After Chicago the Board had several serious discussions about the lessons learned from this seven and what we should do next. We agreed to apply those lessons and continue to invest in this event; there will be a PASS Business Analytics Conference in 2014. I’m very pleased the next event will be in San Jose, CA, the heart of Silicon Valley, a place where a great deal of investment and innovation in data analytics is taking place. Global SQL Community Over the last couple of years PASS has been taking steps to become more relevant to SQL communities in different parts of the world. In May I had the opportunity to attend SQL Bits XI in Nottingham, England. It was enlightening to meet and talk with SQL professionals from around the U.K. as well as many other European countries. The many SQL Bits volunteers put on a great event and were gracious hosts. Budgets The Board passed the FY14 budget at the end of June. The  budget process can be challenging and requires the Board to make some difficult choices about where to allocate resources. Overall I’m satisfied with the decisions we made and think we are investing in the right activities and programs. Next Up The Board is meeting July 18-19 in Kansas City. We will be holding the Executive Committee election for the Exec Co that will take office in 2014. We will also be discussing plans for the next BA conference as well as the next steps for our Global Growth initiative. Applications for the upcoming Board of Directors election open on July 24. If you are considering running for the Board you can visit the PASS elections site to learn more about the election process. And I encourage anyone considering running to reach out to current and past Board members to learn about what the role entails. Plans for the next PASS Summit are in full swing. We are working on some fun new ideas to introduce attendees to the many ways to become involved in the SQL community.

• Oracle Solaris Crash Analysis Tool 5.3 now available

  - by user12609056

  Oracle Solaris Crash Analysis Tool 5.3 The Oracle Solaris Crash Analysis Tool Team is happy to announce the availability of release 5.3.  This release addresses bugs discovered since the release of 5.2 plus enhancements to support Oracle Solaris 11 and updates to Oracle Solaris versions 7 through 10. The packages are available on My Oracle Support - simply search for Patch 13365310 to find the downloadable packages. Release Notes General blast support The blast GUI has been removed and is no longer supported. Oracle Solaris 2.6 Support As of Oracle Solaris Crash Analysis Tool 5.3, support for Oracle Solaris 2.6 has been dropped. If you have systems running Solaris 2.6, you will need to use Oracle Solaris Crash Analysis Tool 5.2 or earlier to read its crash dumps. New Commands Sanity Command Though one can re-run the sanity checks that are run at tool start-up using the coreinfo command, many users were unaware that they were. Though these checks can still be run using that command, a new command, namely sanity, can now be used to re-run the checks at any time. Interface Changes scat_explore -r and -t option The -r option has ben added to scat_explore so that a base directory can be specified and the -t op[tion was added to enable color taggging of the output. The scat_explore sub-command now accepts new options. Usage is: scat --scat_explore [-atv] [-r base_dir] [-d dest] [unix.N] [vmcore.]N Where: -v Verbose Mode: The command will print messages highlighting what it's doing. -a Auto Mode: The command does not prompt for input from the user as it runs. -d dest Instructs scat_explore to save it's output in the directory dest instead of the present working directory. -r base_dir Instructs scat_explore to save it's under the directory base_dir instead of the present working directory. If it is not specified using the -d option, scat_explore names it's output file as "scat_explore_system_name_hostid_lbolt_value_corefile_name." -t Enable color tags. When enabled, scat_explore tags important text with colors that match the level of importance. These colors correspond to the color normally printed when running Oracle Solaris Crash Analysis Tool in interactive mode. Tag Name Definition FATAL An extremely important message which should be investigated. WARNING A warning that may or may not have anything to do with the crash. ERROR An error, usually printer with a suggested command ALERT Used to indicate something the tool discovered. INFO Purely informational message INFO2 A follow-up to an INFO tagged message REDZONE Usually used when prnting memory info showing something is in the kernel's REDZONE. N The number of the crash dump. Specifying unix.N vmcore.N is optional and not required. Example: $ scat --scat_explore -a -v -r /tmp vmcore.0 #Output directory: /tmp/scat_explore_oomph_833a2959_0x28800_vmcore.0 #Tar filename: scat_explore_oomph_833a2959_0x28800_vmcore.0.tar #Extracting crash data... #Gathering standard crash data collections... #Panic string indicates a possible hang... #Gathering Hang Related data... #Creating tar file... #Compressing tar file... #Successful extraction SCAT_EXPLORE_DATA_DIR=/tmp/scat_explore_oomph_833a2959_0x28800_vmcore.0 Sending scat_explore results The .tar.gz file that results from a scat_explore run may be sent using Oracle Secure File Transfer. The Oracle Secure File Transfer User Guide describes how to use it to send a file. The send_scat_explore script now has a -t option for specifying a to address for sending the results. This option is mandatory. Known Issues There are a couple known issues that we are addressing in release 5.4, which you should expect to see soon: Display of timestamps in threads and clock information is incorrect in some cases. There are alignment issues with some of the tables produced by the tool.

• Cloud hosted CI for .NET projects

  - by Scott Dorman

  Originally posted on: http://geekswithblogs.net/sdorman/archive/2014/06/02/cloud-hosted-ci-for-.net-projects.aspxContinuous integration (CI) is important. If you don’t have it set up…you should. There are a lot of different options available for hosting your own CI server, but they all require you to maintain your own infrastructure. If you’re a business, that generally isn’t a problem. However, if you have some open source projects hosted, for example on GitHub, there haven’t really been any options. That has changed with the latest release of AppVeyor, which bills itself as “Continuous integration for busy developers.” What’s different about AppVeyor is that it’s a hosted solution. Why is that important? By being a hosted solution, it means that I don’t have to maintain my own infrastructure for a build server. How does that help if you’re hosting an open source project? AppVeyor has a really competitive pricing plan. For an unlimited amount of public repositories, it’s free. That gives you a cloud hosted CI system for all of your GitHub projects for the cost of some time to set them up, which actually isn’t hard to do at all. I have several open source projects (hosted at https://github.com/scottdorman), so I signed up using my GitHub credentials. AppVeyor fully supported my two-factor authentication with GitHub, so I never once had to enter my password for GitHub into AppVeyor. Once it was done, I authorized GitHub and it instantly found all of the repositories I have (both the ones I created and the ones I cloned from elsewhere). You can even add “build badges” to your markdown files in GitHub, so anyone who visits your project can see the status of the lasted build. Out of the box, you can simply select a repository, add the build project, click New Build and wait for the build to complete. You now have a complete CI server running for your project. The best part of this, besides the fact that it “just worked” with almost zero configuration is that you can configure it through a web-based interface which is very streamlined, clean and easy to use or you can use a appveyor.yml file. This means that you can define your CI build process (including any scripts that might need to be run, etc.) in a standard file format (the YAML format) and store it in your repository. The benefits to that are huge. The file becomes a versioned artifact in your source control system, so it can be branched, merged, and is completely transparent to anyone working on the project. By the way, AppVeyor isn’t limited to just GitHub. It currently supports GitHub, BitBucket, Visual Studio Online, and Kiln. I did have a few issues getting one of my projects to build, but the same day I posted the problem to the support forum a fix was deployed, and I had a functioning CI build about 5 minutes after that. Since then, I’ve provided some additional feature requests and had a few other questions, all of which have seen responses within a 24-hour period. I have to say that it’s easily been one of the best customer support experiences I’ve seen in a long time. AppVeyor is still young, so it doesn’t yet have full feature parity with some of the older (more established) CI systems available,  but it’s getting better all the time and I have no doubt that it will quickly catch up to those other CI systems and then pass them. The bottom line, if you’re looking for a good cloud-hosted CI system for your .NET-based projects, look at AppVeyor.

• Personal Financial Management – The need for resuscitation

  - by Salil Ravindran

  Until a year or so ago, PFM (Personal Financial Management) was the blue eyed boy of every channel banking head. In an age when bank account portability is still fiction, PFM was expected to incentivise customers to switch banks. It still is, in some emerging economies, but if the state of PFM in matured markets is anything to go by, it is in a state of coma and badly requires resuscitation. Studies conducted around the year show an alarming decline and stagnation in PFM usage in mature markets. A Sept 2012 report by Aite Group – Strategies for PFM Success shows that 72% of users hadn’t used PFM and worse, 58% of them were not kicked about using it. Of the rest who had used it, only half did on a bank site. While there are multiple reasons for this lack of adoption, some are glaringly obvious. While pretty graphs and pie charts are important to provide a visual representation of my income and expense, it is simply not enough to encourage me to return. Static representation of data without any insightful analysis does not help me. Budgeting and Cash Flow is important but when I have an operative account, a couple of savings accounts, a mortgage loan and a couple of credit cards help me with what my affordability is in specific contexts rather than telling me I just busted my budget. Help me with relative importance of each budget category so that I know it is fine to go over budget on books for my daughter as against going over budget on eating out. Budget over runs and spend analysis are post facto and I am informed of my sins only when I return to online banking. That too, only if I decide to come to the PFM area. Fundamentally, PFM should be a part of my banking engagement rather than an analysis tool. It should be contextual so that I can make insight based decisions. So what can be done to resuscitate PFM? Amalgamation with banking activities – In most cases, PFM tools are integrated into online banking pages and they are like chapter 37 of a long story. PFM needs to be a way of banking rather than a tool. Available balances should shift to Spendable Balances. Budget and goal related insights should be integrated with transaction sessions to drive pre-event financial decisions. Personal Financial Guidance - Banks need to think ground level and see if their PFM offering is really helping customers achieve self actualisation. Banks need to recognise that most customers out there are non-proficient about making the best value of their money. Customers return when they know that they are being guided rather than being just informed on their finance. Integrating contextual financial offers and financial planning into PFM is one way ahead. Yet another way is to help customers tag unwanted spending thereby encouraging sound savings habits. Mobile PFM – Most banks have left all those numbers on online banking. With access mostly having moved to devices and the success of apps, moving PFM on to devices will give it a much needed shot in the arm. This is not only about presenting the same wine in a new bottle but also about leveraging the power of the device in pushing real time notifications to make pre-purchase decisions. The pursuit should be to analyse spend, budgets and financial goals real time and push them pre-event on to the device. So next time, I should know that I have over run my eating out budget before walking into that burger joint and not after. Increase participation and collaboration – Peer group experiences and comments are valued above those offered by the bank. Integrating social media into PFM engagement will let customers share and solicit their financial management experiences with their peer group. Peer comparisons help benchmark one’s savings and spending habits with those of the peer group and increases stickiness. While mature markets have gone through this learning in some way over the last one year, banks in maturing digital banking economies increasingly seem to be falling into this trap. Best practices lie in profiling and segmenting customers, being where they are and contextually guiding them to identify and achieve their financial goals. Banks could look at the likes of Simple and Movenbank to draw inpiration from.

• Why do I need two Instances in Windows Azure?

  - by BuckWoody

  Windows Azure as a Platform as a Service (PaaS) means that there are various components you can use in it to solve a problem: Compute “Roles” - Computers running an OS and optionally IIS - you can have more than one "Instance" of a given Role Storage - Blobs, Tables and Queues for Storage Other Services - Things like the Service Bus, Azure Connection Services, SQL Azure and Caching It’s important to understand that some of these services are Stateless and others maintain State. Stateless means (at least in this case) that a system might disappear from one physical location and appear elsewhere. You can think of this as a cashier at the front of a store. If you’re in line, a cashier might take his break, and another person might replace him. As long as the order proceeds, you as the customer aren’t really affected except for the few seconds it takes to change them out. The cashier function in this example is stateless. The Compute Role Instances in Windows Azure are Stateless. To upgrade hardware, because of a fault or many other reasons, a Compute Role's Instance might stop on one physical server, and another will pick it up. This is done through the controlling fabric that Windows Azure uses to manage the systems. It’s important to note that storage in Azure does maintain State. Your data will not simply disappear - it is maintained - in fact, it’s maintained three times in a single datacenter and all those copies are replicated to another for safety. Going back to our example, storage is similar to the cash register itself. Even though a cashier leaves, the record of your payment is maintained. So if a Compute Role Instance can disappear and re-appear, the things running on that first Instance would stop working. If you wrote your code in a Stateless way, then another Role Instance simply re-starts that transaction and keeps working, just like the other cashier in the example. But if you only have one Instance of a Role, then when the Role Instance is re-started, or when you need to upgrade your own code, you can face downtime, since there’s only one. That means you should deploy at least two of each Role Instance not only for scale to handle load, but so that the first “cashier” has someone to replace them when they disappear. It’s not just a good idea - to gain the Service Level Agreement (SLA) for our uptime in Azure it’s a requirement. We point this out right in the Management Portal when you deploy the application: (Click to enlarge) When you deploy a Role Instance you can also set the “Upgrade Domain”. Placing Roles on separate Upgrade Domains means that you have a continuous service whenever you upgrade (more on upgrades in another post) - the process looks like this for two Roles. This example covers the scenario for upgrade, so you have four roles total - One Web and one Worker running the "older" code, and one of each running the new code. In all those Roles you want at least two instances, and this example shows that you're covered for High Availability and upgrade paths: The take-away is this - always plan for forward-facing Roles to have at least two copies. For Worker Roles that do background processing, there are ways to architect around this number, but it does affect the SLA if you have only one.

• Sitting Pretty

  - by Phil Factor

  Guest Editorial for Simple-Talk IT Pro newsletter'DBAs and SysAdmins generally prefer an expression of calmness under adversity. It is a subtle trick, and requires practice in front of a mirror to get it just right. Too much adversity and they think you're not coping; too much calmness and they think you're under-employed' I dislike the term 'avatar', when used to describe a portrait photograph. An avatar, in the sense of a picture, is merely the depiction of one's role-play alter-ego, often a ridiculous bronze-age deity. However, professional image is important. The choice and creation of online photos has an effect on the way your message is received and it is important to get that right. It is fine to use that photo of you after ten lagers on holiday in an Ibiza nightclub, but what works on Facebook looks hilarious on LinkedIn. My splendid photograph that I use online was done by a professional photographer at great expense and I've never had the slightest twinge of regret when I remember how much I paid for it. It is me, but a more pensive and dignified edition, oozing trust and wisdom. One gasps at the magical skill that a professional photographer can conjure up, without digital manipulation, to make the best of a derisory noggin (ed: slang for a head). Even if he had offered to depict me as a semi-naked, muscle-bound, sword-wielding hero, I'd have demurred. No, any professional person needs a carefully cultivated image that looks right. I'd never thought of using that profile shot, though I couldn't help noticing the photographer flinch slightly when he first caught sight of my face. There is a problem with using an avatar. The use of a single image doesn't express the appropriate emotion. At the moment, it is weird to see someone with a laughing portrait writing something solemn. A neutral cast to the face, somewhat like a passport photo, is probably the best compromise. Actually, the same is true of a working life in IT. One of the first skills I learned was not to laugh at managers, but, instead, to develop a facial expression that promoted a sense of keenness, energy and respect. Every profession has its own preferred facial cast. A neighbour of mine has the natural gift of a face that displays barely repressed grief. Though he is characteristically cheerful, he earns a remarkable income as a pallbearer. DBAs and SysAdmins generally prefer an expression of calmness under adversity. It is a subtle trick, and requires practice in front of a mirror to get it just right. Too much adversity and they think you're not coping; too much calmness and they think you're under-employed. With an appropriate avatar, you could do away with a lot of the need for 'smilies' to give clues as to the meaning of what you've written on forums and blogs. If you had a set of avatars, showing the full gamut of human emotions expressible in writing: Rage, fear, reproach, joy, ebullience, apprehension, exasperation, dissembly, irony, pathos, euphoria, remorse and so on. It would be quite a drop-down list on forums, but given the vast prairies of space on the average hard drive, who cares? It would cut down on the number of spats in Forums just as long as one picks the right avatar. As an unreconstructed geek, I find it hard to admit to the value of image in the workplace, but it is true. Just as we use professionals to tidy up and order our CVs and job applications, we should employ experts to enhance our professional image. After all you don't perform surgery or dentistry on yourself do you?

• Grub Rescue Unknown Filesystem Error. Grub Corrupted or Filesystem?

  - by nightcrawler

  Now it has happened twice & have been pulling my hairs now... I have installed xubuntu on my external hardisk & have been using it for about 3 months. It has three partitions, one of 500 mb mounted at /boot, 2nd one of 48gb mounted at / & the rest (out of 160gb) is ntfs partition....used as normal external storage. The last storage supposedly acts as a buffer b/w Linux distributions & Win platform, buffer in the sense that it provides a universal channel for data transfers. I have constantly used this external hardisk for data transfers b/w win7 laptop & xubuntu (on this external hd) without any hassle. However, on of my desktops where I have ubuntu I (for the first time) attached this external drive which let me do data transfers where all three partitions properly mounted....but then nasty thing occurred the same that occurred before. I (as usual) tried booting via this external hd (one having xubuntu, one having being formerly used under Ubuntu) I got error Now I am totally devastated because similar thing happened ~6months before when I had fedora 17 in my external hd (instead of xubuntu) & after it was used under ubuntu the same happened...i didn't reported it because I already had planned towards debian instead of rpm! The mystery is that as long as I don't attach this external hd under ubuntu the data never** corrupts whereas under win xp/7 I can use it as a normal usb storage of coarse linux partitions aren’t available under win platforms... **From corrupts I mean hd fails to boot with the error mentioned however cant say whether data within remains untouched? It seems that my grub & or MBR is corrupted.

• Type of computer for a developer on the road

  - by nabucosound

  Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

• Strings in .NET are Enumerable

  - by Scott Dorman

  It seems like there is always some confusion concerning strings in .NET. This is both from developers who are new to the Framework and those that have been working with it for quite some time. Strings in the .NET Framework are represented by the System.String class, which encapsulates the data manipulation, sorting, and searching methods you most commonly perform on string data. In the .NET Framework, you can use System.String (which is the actual type name or the language alias (for C#, string). They are equivalent so use whichever naming convention you prefer but be consistent. Common usage (and my preference) is to use the language alias (string) when referring to the data type and String (the actual type name) when accessing the static members of the class. Many mainstream programming languages (like C and C++) treat strings as a null terminated array of characters. The .NET Framework, however, treats strings as an immutable sequence of Unicode characters which cannot be modified after it has been created. Because strings are immutable, all operations which modify the string contents are actually creating new string instances and returning those. They never modify the original string data. There is one important word in the preceding paragraph which many people tend to miss: sequence. In .NET, strings are treated as a sequence…in fact, they are treated as an enumerable sequence. This can be verified if you look at the class declaration for System.String, as seen below: // Summary:// Represents text as a series of Unicode characters.public sealed class String : IEnumerable, IComparable, IComparable<string>, IEquatable<string> The first interface that String implements is IEnumerable, which has the following definition: // Summary:// Exposes the enumerator, which supports a simple iteration over a non-generic// collection.public interface IEnumerable{ // Summary: // Returns an enumerator that iterates through a collection. // // Returns: // An System.Collections.IEnumerator object that can be used to iterate through // the collection. IEnumerator GetEnumerator();} As a side note, System.Array also implements IEnumerable. Why is that important to know? Simply put, it means that any operation you can perform on an array can also be performed on a string. This allows you to write code such as the following: string s = "The quick brown fox";foreach (var c in s){ System.Diagnostics.Debug.WriteLine(c);}for (int i = 0; i < s.Length; i++){ System.Diagnostics.Debug.WriteLine(s[i]);} If you executed those lines of code in a running application, you would see the following output in the Visual Studio Output window: In the case of a string, these enumerable or array operations return a char (System.Char) rather than a string. That might lead you to believe that you can get around the string immutability restriction by simply treating strings as an array and assigning a new character to a specific index location inside the string, like this: string s = "The quick brown fox";s[2] = 'a';   However, if you were to write such code, the compiler will promptly tell you that you can’t do it: This preserves the notion that strings are immutable and cannot be changed once they are created. (Incidentally, there is no built in way to replace a single character like this. It can be done but it would require converting the string to a character array, changing the appropriate indexed location, and then creating a new string.)

• The battle between Java vs. C#

  The battle between Java vs. C# has been a big debate amongst the development community over the last few years. Both languages have specific pros and cons based on the needs of a particular project. In general both languages utilize a similar coding syntax that is based on C++, and offer developers similar functionality. This being said, the communities supporting each of these languages are very different. The divide amongst the communities is much like the political divide in America, where the Java community would represent the Democrats and the .Net community would represent the Republicans. The Democratic Party is a proponent of the working class and the general population. Currently, Java is deeply entrenched in the open source community that is distributed freely to anyone who has an interest in using it. Open source communities rely on developers to keep it alive by constantly contributing code to make applications better; essentially they develop code by the community. This is in stark contrast to the C# community that is typically a pay to play community meaning that you must pay for code that you want to use because it is developed as products to be marketed and sold for a profit. This ties back into my reference to the Republicans because they typically represent the needs of business and personal responsibility. This is emphasized by the belief that code is a commodity and that it can be sold for a profit which is in direct conflict to the laissez-faire beliefs of the open source community. Beyond the general differences between Java and C#, they also target two different environments. Java is developed to be environment independent and only requires that users have a Java virtual machine running in order for the java code to execute. C# on the other hand typically targets any system running a windows operating system and has the appropriate version of the .Net Framework installed. However, recently there has been push by a segment of the Open source community based around the Mono project that lets C# code run on other non-windows operating systems. In addition, another feature of C# is that it compiles into an intermediate language, and this is what is executed when the program runs. Because C# is reduced down to an intermediate language called Common Language Runtime (CLR) it can be combined with other languages that are also compiled in to the CLR like Visual Basic (VB) .Net, and F#. The allowance and interaction between multiple languages in the .Net Framework enables projects to utilize existing code bases regardless of the actual syntax because they can be compiled in to CLR and executed as one codebase. As a software engineer I personally feel that it is really important to learn as many languages as you can or at least be open to learn as many languages as you can because no one language will work in every situation.  In some cases Java may be a better choice for a project and others may be C#. It really depends on the requirements of a project and the time constraints. In addition, I feel that is really important to concentrate on understanding the logic of programming and be able to translate business requirements into technical requirements. If you can understand both programming logic and business requirements then deciding which language to use is just basically choosing what syntax to write for a given business problem or need. In regards to code refactoring and dynamic languages it really does not matter. Eventually all projects will be refactored or decommissioned to allow for progress. This is the way of life in the software development industry. The language of a project should not be chosen based on the fact that a project will eventually be refactored because they all will get refactored.

• Top 5 characteristics Recruiters are looking for

  - by Maria Sandu

  Of course many skills and characteristics recruiters are looking for are job specific. But whether you are a graduate fresh out of college or seasoned in the workplace, recruiters are also looking for generic skills and attitude to see whether you are a good fit to the company. So make sure you prepare and show through examples that you have these skills. 1. Drive/passion Liking the job you are applying for is paramount and something recruiters are always looking for. Show and prove your drive for the role and/or the field you are applying for. Always be prepared to pitch yourself, this shows your drive in the role you are applying for. 2. Communication skills People often make the mistake by thinking this skill is related to how good they are able to talk about their background and expertise. This is important, but as least as important is it that you listen well to questions that are asked. Make sure you answer to the point and ask questions if you want questions to be clarified. This shows your interest in the role and the ability to communicate clearly. This also helps you building trust with the recruiter every time you speak to him/her. 3. Confidence Recruiters are looking for the best candidate for the job. So if you don’t think you are the best candidate why should the recruiter? Show with confidence, without being arrogant (think about building trust), why you are the right person for the job. Confidence also shows in your answers to difficult questions. Be confident enough to explain why some experiences went wrong and how you learnt from them. If you don’t have a direct explanation on a question, it is better to ask for a second to think instead of a random answer. 4. Vision The main reason to hire graduates for many companies is that graduates are perceived to be flexible. The organisation will train and up skill you in the direction best suitable for the organisation. However the most intense learning path is realised when you also know where you want to go. Companies are often happy to accommodate you to support with training and development, but if you don’t have a clear vision on what you want to achieve for yourself and what value you bring to the company, recruiters can decide you are not the right candidate as they are afraid you aren’t going to stay in the company. 5. Business awareness For every job you apply you will get challenged on your knowledge and interest for the market and business they are in. All companies add value in different ways in their respective markets. So make sure you are aware of what a company is doing, what their goal is and why and how they exist and how you can add value for the company in the role you are applying for. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Oracle is a place that brings together talented people from various countries and with a diversity of backgrounds. We often invite our employees to speak about their life at Oracle as we think It is important to share an insight into what working for our company looks like. This time we asked Stanislav to speak about his experience at Oracle. He is Technology Sales Manager at Oracle Russia. He joined the company in July 2011 as a Sales Representative for the Financial sector and had previously worked for another American IT company. He was promoted to a Management position in 2013. “I have been in this Industry for 15 years and I am now Technology Sales Manager, covering Database, BI and Fusion Middleware products. What I’ve learned in my role is that respect is one of the most important values a good professional should have. By respecting and embracing everyone’s opinions, we create a very good work environment that encourages innovation and change. It eventually leads to a stronger team where people listen to each other and value each other’s opinion. On the other hand, It is mandatory to have good knowledge about the area you work in and to continously seek to improve your expertise. Last but not least, working as a team is a top priority and It is something that I’ve learned at Oracle. There’s little you can achieve by yourself comparing to what you can do when you’re part of a team.” Stanislav shared the top three words that best describe his team and those were: professional, dynamic and smart. “The team I manage is a very professional, dynamic and smart one. I am really proud to work with such talented people! They are an asset to the Oracle business because they are the very best in the IT industry worldwide!” When asked why he would apply at Oracle if he was looking for a job, Stanislav responded “I would say because Oracle is a legend of the IT industry.

• Moving abroad - Relocation advice

  - by Tim Koekkoek

  Oracle offers graduates from different European countries the opportunity to start their career abroad. Some already have experience with living abroad as they have done an exchange semester or internship in another county, for others it is the first time they will move abroad. Rui started in October 2011 as a Business Development Consultant in Dublin and moved from Portugal to Dublin, Ireland to start his career. For those planning to leave their home country and who desire to work abroad, he will share some tips and tricks in this article. When you’re faced with an opportunity like this, there are lots of things that will come to your mind. Sometimes it can be either very exciting, or even stressful. 1. First of all, try to relax. If you are certain you are moving abroad, all you need to do is some research about the country where you’re going to live, get to know its culture (gastronomy, important dates and events, its economy and effective ways to keep you in touch with your family and friends – such as mobile companies and Internet services), and start to understand the best locations (with good access) you could/should live in are. Don’t forget that initially you can be limited by transport and therefore it is important to explore the ideal places for you. During this time, Oracle provides everything you’ll need (papers, documents, etc.) to cross borders. 2. When you arrive, you understand that you are in a new country, in a new place, where all things (or most) are unknown to you. Before you panic, try to see it as a new challenge where new opportunities will come. Sometimes, it’s not easy I know, but the very best a new place has to give to you, is the opportunity to understand a new culture, get to know other people, other ways of working, and grow both as a person and professionally. So, you have nothing to lose in this kind of experiment. 3. When you arrive at Oracle, there’s a fantastic team that will help you with settling in, HR, Payroll, Relocation, IT. In my case, Oracle helped me with the relocation, they supported me to arrange everything such as helping out with all the paperwork and finding a new apartment. As you can see they will do their best to help you to be successful! 4. Engage with your new co-workers. Going to a place where you don’t know anyone can be tough sometimes but see it as an opportunity to meet people from all over the world and share experiences. Embrace it. 5. Plan ahead, try to get the most information possible and use it. Oracle is a multinational enterprise that will allow you to get to know a new labour market and give you the flexibility you need to understand your view of employment and occupation, giving you the very best opportunities to join different teams and working areas, so that you can work where you fit best. Good luck! If you’re thinking about starting a career abroad, read the following article: http://www.overseasdigest.com/movingtips.htm it can be very useful to you.

• Get More From Your Service Request

  - by Get Proactive Customer Adoption Team

  Leveraging Service Request Best Practices Use best practices to get there faster. In the daily conversations I have with customers, they sometimes express frustration over their Service Requests. They often feel powerless to make needed changes, so their sense of frustration grows. To help you avoid some of the frustration you might feel in dealing with your Service Requests (SR), here are a few pointers that come from our best practice discussions. Be proactive. If you can anticipate some of the questions that Support will ask, or the information they may need, try to provide this up front, when you log the SR. This could be output from the Remote Diagnostic Agent (RDA), if this is a database issue, or the output from another diagnostic tool, if you’re an EBS customer. Any information you can supply that helps us understand the situation better, helps us resolve the issue sooner. As you use some of these tools proactively, you might even find the solution to the problem before you log an SR! Be right. Make sure you have the correct severity level. Since you select the initial severity level, it’s easy to accept the default without considering how significant this may be. Business impact is the driving factor, so make sure you take a moment to select the severity level that is appropriate to the situation. Also, make sure you ask us to change the severity level, should the situation dictate. Be responsive! If this is an important issue to you, quickly follow up on any action plan submitted to you by Oracle Support. The support engineer assigned to your Service Request will be able to move the issue forward more aggressively when they have the needed information. This is crucial in resolving your issues in a timely manner. Be thorough. If there are five questions in the action plan, make sure you provide an answer for all five questions in one response, rather than trickling them in one at a time. This will allow the engineer to look at all of the information as a whole and to avoid multiple trips to your SR, saving valuable time and getting you a resolution sooner. Be your own advocate! You know your situation best; make sure Oracle Support understands both how and why this issue is important to you and your company. Use the escalation process if you're concerned that your SR isn't going the right direction, the right pace, or through the right person. Don't wait until you're frustrated and angry. An escalation is as simple as a quick conversation on the phone and can be amazingly effective in getting your issues back on track. The support manager you speak with is empowered to make any needed changes. Be our partner. You can make your support experience better. When your SR has been resolved, you may receive a survey request. This is intended to get your feedback about how your SR went and what we can do to improve your overall support experience. Oracle Support is here to help you. Our goal with any Service Request is to provide the best possible solution as quickly as possible. With your help, we’ll be able to do this with your Service Request too.

• Web Service Example - Part 3: Asynchronous

  - by Denis T

  In this edition of the ADF Mobile blog we'll tackle part 3 of our Web Service examples.  In this posting we'll take a look at firing the web service asynchronously and then filling in the UI when it completes.  This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data. Getting the sample code: Just click here to download a zip of the entire project.  You can unzip it and load it into JDeveloper and deploy it either to iOS or Android.  Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed.  Note: This is a different workspace than WS-Part2 What's different? In this example, when you click the Search button on the Forecast By Zip option, now it takes you directly to the results page, which is initially blank.  When the web service returns a second or two later the data pops into the UI.  If you go back to the search page and hit Search it will again clear the results and invoke the web service asynchronously.  This isn't really that useful for this particular example but it shows an important technique that can be used for other use cases. How it was done 1)  First we created a new class, ForecastWorker, that implements the Runnable interface.  This is used as our worker class that we create an instance of and pass to a new thread that we create when the Search button is pressed inside the retrieveForecast actionListener handler.  Once the thread is started, the retrieveForecast returns immediately.  2)  The rest of the code that we had previously in the retrieveForecast method has now been moved to the retrieveForecastAsync.  Note that we've also added synchronized specifiers on both these methods so they are protected from re-entrancy. 3)  The run method of the ForecastWorker class then calls the retrieveForecastAsync method.  This executes the web service code that we had previously, but now on a separate thread so the UI is not locked.  If we had already shown data on the screen it would have appeared before this was invoked.  Note that you do not see a loading indicator either because this is on a separate thread and nothing is blocked. 4)  The last but very important aspect of this method is that once we update data in the collections from the data we retrieve from the web service, we call AdfmfJavaUtilities.flushDataChangeEvents().   We need this because as data is updated in the background thread, those data change events are not propagated to the main thread until you explicitly flush them.  As soon as you do this, the UI will get updated if any changes have been queued. Summary of Fundamental Changes In This Application The most fundamental change is that we are invoking and handling our web services in a background thread and updating the UI when the data returns.  This allows an application to provide a better user experience in many cases because data that is already available locally is displayed while lengthy queries or web service calls can be done in the background and the UI updated when they return.  There are many different use cases for background threads and this is just one example of optimizing the user experience and generating a better mobile application.

• Cloud Fact for Business Managers #3: Where You Data Is, and Who Has Access to It Might Surprise You

  - by yaldahhakim

  Written by: David Krauss While data security and operational risk conversations usually happen around the desk of a CCO/CSO (chief compliance and/or security officer), or perhaps the CFO, since business managers are now selecting cloud providers, they need to be able to at least ask some high-level questions on the topic of risk and compliance.  While the report found that 76% of adopters were motivated to adopt cloud apps because of quick access to software, most of these managers found that after they made a purchase decision their access to exciting new capabilities in the cloud could be hindered due to performance and scalability constraints put forth  by their cloud provider.  If you are going to let your business consume their mission critical business applications as a service, then it’s important to understand who is providing those cloud services and what kind of performance you are going to get.  Different types of departments, companies and industries will all have unique requirements so it’s key to take this also into consideration.   Nothing puts a CEO in a bad mood like a public data breach or finding out the company lost money when customers couldn’t buy a product or service because your cloud service provider had a problem.  With 42% of business managers having seen a data security breach in their department associated directly with the use of cloud applications, this is happening more than you think.   We’ve talked about the importance of being able to avoid information silos through a unified cloud approach and platform.  This is also important when keeping your data safe and secure, and a key conversation to have with your cloud provider.  Your customers want to know that their information is protected when they do business with you, just like you want your own company information protected.   This is really hard to do when each line of business is running different cloud application services managed by different cloud providers, all with different processes and controls.   It only adds to the complexity, and the more complex, the more risky and the chance that something will go wrong. What about compliance? Depending on the cloud provider, it can be difficult at best to understand who has access to your data, and were your data is actually stored.  Add to this multiple cloud providers spanning multiple departments and it becomes very problematic when trying to comply with certain industry and country data security regulations.  With 73% of business managers complaining that having cloud data handled externally by one or more cloud vendors makes it hard for their department to be compliant, this is a big time suck for executives and it puts the organization at risk. Is There A Complete, Integrated, Modern Cloud Out there for Business Executives?If you are a business manager looking to drive faster innovation for your business and want a cloud application that your CIO would approve of, I would encourage you take a look at Oracle Cloud.  It’s everything you want from a SaaS based application, but without compromising on functionality and other modern capabilities like embedded business intelligence, social relationship management (for your entire business), and advanced mobile.  And because Oracle Cloud is built and managed by Oracle, you can be confident that your cloud application services are enterprise-grade.  Over 25 Million users and 10 thousands companies around the globe rely on Oracle Cloud application services everyday – maybe your business should too.  For more information, visit cloud.oracle.com.

He adds that process manufacturing organizations such as oil and gas, utilities, and chemicals must manage this level of investment in an environment of constrained capital markets, erratic supply and demand, aging infrastructure, heightened regulations, and declining global skills. In the following interview, Graham explains how the right enterprise project portfolio management (EPPM) technology can help the industry meet these imperatives. Q: Why is EPPM so important for today’s process manufacturers? A: If the industry invests US$38 trillion without proper cost controls in place, a huge amount of resources will be put at risk, especially when it comes to cost overruns that may occur in large capital projects. Process manufacturing companies must not only control costs, but also monitor all the various contractors that will be involved in each project. If you’re not managing your own workers and all the interdependencies among the different contractors, then you’ve got problems. Q: What else should process manufacturers look for? A: It’s also important that an EPPM solution has the ability to manage more than just capital projects. For example, it’s best to manage maintenance and capital projects in the same system. Say you’re due to install a new transformer in a power station as part of a capital project, but routine maintenance in that area of the facility is scheduled for that morning. The lack of coordination could lead to unforeseen delays. There are also IT considerations that impact capital projects, such as adding servers and network cable for a control system in a power station. What organizations need is a true EPPM system that’s not just for capital projects, maintenance, or IT activities, but instead an enterprisewide solution that provides visibility into all types of projects. Read the complete Q&A here and discover the practical framework for successfully managing this massive capital spending.

• jqGrid Coloring an entire line in Grid based upon a cells value

  - by Thomas

  Hi all, i know it's been asked before but i cant get it to run and i'm out of things to try. So i want to colorize a row in a Grid if its value is not 1 - i use a custom formatter for this. The formatter itself works, thats not the problem. I've tried multple ways I've found so far on the web - adding a class, directly adding css code, using setRowData, using setCell.... Here are my examples - none of them worked for me (linux, ff363) - any pointer would be gratly appreciated. 27.05.2010_00:00:00-27.05.2010_00:00:00 is my row id <style> .state_inactive { background-color: red !important; } .state_active { background-color: green !important; } </style> function format_state (cellvalue, options, rowObject) { var elem='#'+options.gid; if (cellvalue != 1) { jQuery('#list2').setRowData(options.rowID,'', {'background-color':'#FF6F6F'}); jQuery('#list2').setRowData('27.05.2010_00:00:00-27.05.2010_00:00:00', '',{'background-color':'#FF6F6F'}); for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_inactive',''); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'','state_inactive'); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'5', {'background-color':'#FF6F6F'},''); } } else { for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_active',''); } } <!-- dont modify, we simply added the class above--> return cellvalue; } Thanks, Thomas

• WPF touch and slide/drag animation

  - by George

  I'm trying to create a pretty simple WPF interface, and from what I know this should be mostly possible using pure XAML. What I know I have a pretty basic understanding of WPF so far, however I have a decent grasp on XAML. I know or can work out how to put content in these panels. This isn't the topic of this question. What I don't know I don't know how to animate this interface. I'm not very proficient at binding, however again, that's not the topic of this question. The topic of this question is what would be the best way to animate panels 1-4 (images below) so that they may be dragged (via touch) into view. The number of panels here may be static for the purpose of this question. The panels (1-4) can be stack panels, grids or whatever; their content isnt important. What is important is the container that would contain all 4 panels. The complication in this animation is the other two containers here (Item One/TODO), as they're in the way of a smooth animation. If it makes this question simpler, the touch features can be ignored for now, and a simple button push can slide the containers across. One Two

• Fast string suffix checking in C# (.NET 4.0)?

  - by ilitirit

  What is the fastest method of checking string suffixes in C#? I need to check each string in a large list (anywhere from 5000 to 100000 items) for a particular term. The term is guaranteed never to be embedded within the string. In other words, if the string contains the term, it will be at the end of the string. The string is also guaranteed to be longer than the suffix. Cultural information is not important. These are how different methods performed against 100000 strings (half of them have the suffix): 1. Substring Comparison - 13.60ms 2. String.Contains - 22.33ms 3. CompareInfo.IsSuffix - 24.60ms 4. String.EndsWith - 29.08ms 5. String.LastIndexOf - 30.68ms These are average times. [Edit] Forgot to mention that the strings also get put into separate lists, but this is not important. It does add to the running time though. On my system substring comparison (extracting the end of the string using the String.Substring method and comparing it to the suffix term) is consistently the fastest when tested against 100000 strings. The problem with using substring comparison though is that Garbage Collection can slow it down considerably (more than the other methods) because String.Substring creates new strings. The effect is not as bad in .NET 4.0 as it was in 3.5 and below, but it is still noticeable. In my tests, String.Substring performed consistently slower on sets of 12000-13000 strings. This will obviously differ between systems and implementations. [EDIT] Benchmark code: http://pastebin.com/smEtYNYN

• When do married programmers find time to work?

  - by dave-keiture

  Hi people, Maybe my problem is unique (though I don't believe so), and probably I should go with it to the psychologist, but sinse I get married (~year ago) I feel that I don't have enough time to work anymore. For years I've been working at my day job doing regular stuff, and at nights I've been committing to the opensource projects, freelancing and self-educating. Now, I can't work at home at all, because once I start working, my wife either says that there're more important thing to do (walk out the dog, buy something in a grocery, etc.) or that I don't pay anough attention to her.. As a workaround, I've started getting up at 3-4AM in the morning to do the things I was usually doing nightly before. After a month of such schedule I feel myself totally crushed. So... 2 questions: Do you have the same problems, or I'm just a <..., who should say goodbye to programming, and start doing "really important things"? If you have the same problems, when do you find time to work? Maybe you know any cool lifehack or trick to spend at least some tome for doing the thing you like :) Best regards.

• How to prevent latex memory overflow

  - by drasto

  I've got a latex macro that makes small pictures. In that picture I need to draw area. Borders of that area are quadratic bezier curves and that area is to be filled. I did not know how to do it so currently I'm "filling" the area by drawing a plenty of bezier curves inside it... This slows down typeseting and when a macro is used multiple times (so tex is drawing really a lot of quadratic bezier curves) it produces following error: ! TeX capacity exceeded, sorry [main memory size=3000000]. How can I prevent this error ? (by freeing memory after macro or such...) Or even better how do I fill the area determined by two quadratic bezier curves? Code that produces error: \usepackage{forloop} \usepackage{picture} \usepackage{eepic} ... \linethickness{\lineThickness\unitlength}% \forloop[\lineThickness]{cy}{\cymin}{\value{cy} < \cymax}{% \qbezier(\ax, \ay)(\cx, \value{cy})(\bx, \by)% }% Here are some example values for variables: \setlength{\unitlength}{0.01pt} \lineThickness=20 %cy is just a counter - inital value is not important \cymin=450 \cymax=900 %from following only the difference between \ax and \bx is important \ax=0 \ay=0 \bx=550 \by=0 Note: To reproduce the error this code have to execute approximately 150 times (could be more depending on your latex memory settings). Thanks a lot for any help
