  • Ubuntu open to greater touch

    <b>The Register:</b> "You'll want to touch Ubuntu in personal places - like in your kitchen or in your car. At least that's what Canonical hopes, as it works on architectural changes and business deals to put the Linux distro on more embedded systems."

  • Is there any hard data on the (dis-)advantages of working from home?

    - by peterchen
    Is there any hard data (studies, comparisons, not-just-gut-feel analysis) on the advantages and disadvantages of working from home? My devs asked about e.g. working from home one day per week, the boss doesn't like it for various reasons, some of which I agree with but I think they don't necessarily apply in this case. We have real offices (2..3 people each), distractions are still common. IMO it would be beneficial for focus, and with 1 day / week, there wouldn't be much loss at interaction and communication. In addition it would be a great perk, and saving the commute. Related: Pros and Cons of working Remotely/from Home (interesting points, but no hard facts) [edit] Thanks for all the feedback! To clarify: it's not my decision to make, I agree that there are pro's and con's depending on circumstances, and we are pushing for "just try it". I've asked this specific question because (a) facts are a good addition to thoughts in arguing with an engineer boss, and (b) we, as developers, should build upon facts like every respectable trade.

  • Choices in Architecture, Design, Algorithms, Data Structures for effective RDF Reasoning and Querying in a Big Data Environment [on hold]

    - by user2891213
    As part of my academic project I would like to know what choices in Architecture, Design, Algorithms, Data Structures do we need in order to provide effective and efficient RDF Reasoning and Querying in a Big Data Environment. Basically I want to get info regarding below points: What are the Systems and Software to get appropriate Architecture? What kind of API layer(s) would we need on top of the Big Data stores, to make this possible? The Indexing structures we will need. The appropriate Algorithms, and appropriate Algorithms for Query Planning across Big Data stores. The Performance Analysis and Cost Models we will need to justify the design decisions we have made along the way. Can anyone please provide pointers.. Thanks, David

  • R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

    - by user793553
    If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

  • Optimize bootup sequence

    - by ubuntudroid
    I'm on Ubuntu 11.04 (upgraded from 10.10) and suffering really high bootup times. It got so annoying, that I decided to dive into bootchart analysis myself. Therefore I installed bootchart and restarted the system which generated this chart. However, I'm not really experienced in reading such stuff. What causes the long bootup sequence? Edit: Here is the output of hdparm -i /dev/sda: /dev/sda: Model=SAMSUNG HD501LJ, FwRev=CR100-12, SerialNo=S0MUJ1EQ102621 Config={ Fixed } RawCHS=16383/16/63, TrkSize=34902, SectSize=554, ECCbytes=4 BuffType=DualPortCache, BuffSize=16384kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=976773168 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=no WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7 * signifies the current active mode And here the output of hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2410 MB in 2.00 seconds = 1205.26 MB/sec Timing buffered disk reads: 258 MB in 3.02 seconds = 85.50 MB/sec

  • Queries barely over the Cost Threshold for Parallelism

    - by jchang
    Previously I had discussed SQL Server parallelism, with my thoughts on the best settings for: Cost Threshold for Parallelism (CTP) and Max Degrees of Parallelism (MAXDOP) in Parallelism Strategy and Comments . At the time, I had intended to follow up with detailed measurements. So now a mere 2 years later, here it is. The general thought was that CTP should be raised from the default value of 5, and MAXDOP should be changed from unrestricted, on modern systems with very many cores, and most especially...(read more)

  • Archiving your contact form data.

    I get TONS of email from customer. Over time, this email helps me to determine what areas in our product collection are opportunities for enhancement or improvement. I store the email that comes from my blog contact form in folders and then search through them looking for trends periodically. It occurred to me that, while I need to get the emails because many of them are actionable, it would be great if I could use reporting and analysis tools against the collection. So I whipped together...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • Really, Mobile Devices will Take Over the World?

    - by p.gielens
    My blog has been quiet for quite a while. My inspiration comes from crunching/exchanging information which I should do more often. Gartner analysis tells us that by 2013 mobile phones will overtake PC’s as the most common Web access device worldwide. A few years back I would have said non sense, but apparently most Web users are comfortable with less processing power. Just take a look at the increasing business in Netbooks. Wouldn’t it be great to have a mobile phone which can connect wirelessly to my home TV, monitor, car display, mouse, keyboard, etc? And to have the processing power of the current Netbook generation? Where can I buy it? Why are we making our PC devices (for instance the slate) smaller while we can make our mobile device’s functionality bigger? What about the single responsibility principle? Does it apply to physical devices as well as good object-oriented software?

  • Structuring an input file

    - by Ricardo
    I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

  • Oracle 12c: First (and best!) on Solaris

    - by mgerdts
    Oracle 12c is now available for download.  Notice that support for Solaris SPARC and x86-64 are among the operating systems supported on the first day of availability. New database features that relate to Solaris include: I/O outlier support.  This is made possible through the database's use of DTrace, and as such Solaris has a clear edge here. Oracle ACFS Replication and Tagging for Solaris Integration with Solaris resource pools As has been the case for some time, Oracle databases are supported in zones.

  • How to interpret Google's "Avg. Page Load Time"?

    - by hawbsl
    Is there any industry rule of thumb for what's considered an unacceptable load time v. an OK one v. a blistering fast one? We're just reviewing some Google Analytics data and getting 0.74 Avg. Page Load Time reported. I guess that's OK. However it would be good if some meatier comparison data were available, or a blog post, or somewhere where there's some analysis of what speeds are generally being achieved by various kinds of sites. Any useful links to help someone interpret these speeds? If you Google it you just get a lot of results dealing with how to improve your speed. We're not at that stage yet.
