  • Should I be put off a junior role that uses an online development test?

    - by Ninefingers
    I've applied for a junior development role, or rather been found by a recruiter looking for a developer. In order to get to a telephone interview stage I've been asked to sit one of those online coding assessments. This wasn't quite what I expected. I consider myself a fairly good developer for my age and experience, but I've no illusions about being Don Knuth or anything. The test was a series of incredibly obtuse questions asking about the results of various obscure evaluations. About 30 minutes in I was thinking to myself I hadn't intended to enter an obfuscated code contest/code golf exercise. After my last telephone interview I was asked to build something. I did. That seemed fair. Go away and work this out is more my in office experience of programming than "please evaluate this combination of lambdas, filters, maps, lists, tuples etc". So I'm a little put off, to be honest. I never claimed to know the language inside out or all the little corner cases. My questions, then: Should I be put off? Why? Why not? Are these kinds of tests what I should be expecting for junior roles? Should I learn stuff exam style? That seems to be the objective of these tests, for which you are timed and not supposed to use references or books? Normally, in the course of development I have a fairly good idea of basic types, rules, flow control and whatever. Occasionally I'll come up on something I need to use a regex for and have to go and remind myself of the exact piece of syntax I need if trying what I think should work doesn't. Or I'll come up against a module I've not used before and go and look it up. For example, if I wanted to write a server using sockets in C right now, I'd probably check the last piece of code I wrote doing that (and or the various books I have) and work from there. Chances are I probably couldn't do it exactly from scratch and from memory, although I can tell you you'd need a socket(), bind(), listen() and accept() call and you might also want select() depending on whether you intend to pthread_create or not. So I know what the calls are, but not their specific parameter list. What are your experiences if you are a recruiting manager? Are you after programmers who can quote you the API or do you not mind if your programmers have a few books on their desk and google function calls every so often?

  • How to query Oracle from SQL Server ?

    - by Albert Widjaja
    Hi Everyone, I'm having difficulties in creating a connection from my SQL Server 2008 Enterprise SP2 x64 into the Oracle database 10g even though I have already install the Oracle Client 11g R2 ? I've followed this article from steps URL: http://www.ideaexcursion.com/2009/01/05/connecting-to-oracle-from-sql-server/ plus added: TNS_ADMIN into the Server variables which point into: C:\Oracle\product\11.2.0\client_1\network\admin what is working now: TNSNAMES.ORA has been copied successfully from the other Developer wworkstation i can TNSPING into the DB instance i can connect to the database using SQLplus and perform any SQL commands i can create the DSN ONLY when using "[b]C:\Windows\SysWOW64\odbcad32.exe[/b]" the normal odbcad32 doesn't show my DSN that I have just created ? the DSN created from the above works fine from the test connection. my goal: To be able to select the Oracle connection in the Linked server object but still no effect after I restart the server. (Windows Server 2008 Enterprise 64 bit SP2). Any idea please in resolving this problem would be greatly appreciated. Thanks.

  • Tell me what&rsquo;s wrong! &ndash; An XNA sample demonstrating exception handling and reporting in

    - by George Clingerman
    I’ve always enjoyed using Nick Gravelyn’s exception handling in all of my games. You’re always going to encounter those unhandled exception that your players are going to ferret out and having a method to display them rather than just crashing to the dashboard is definitely more of an elegant solution. But the other day I got to thinking…what if we could do more? What if instead of just displaying the error, we could encourage the players to send us the error. So I started playing with that an expanding upon Nick’s sample code to see what I could come up with. I got close to what I envisioned, but unfortunately there were some limitations to just what the XNA API could do. In my head I was picturing the players hitting “Send Message” and a 360 message would just be sent to the XBLIG developer. Unfortunately, you can only send messages in an XNA game to someone you’re currently in a network session with. Since I didn’t want to have a 360 server running all the time, virally connecting to players just to get error messages, I did the next best thing and just open up a 360 message and encourage them to manually enter the gamertag. Maybe someday we’ll be able to do that a little better, but this works for now. In the sample, players can hit the “A” button or key to generate in an exception. If the debugger is not attached, then the Exception message screen will be shown explaining what has happened and giving the player a chance to send a 360 message to the gamertag provided or maybe even just send an email. Nick’s code has been changed just a bit. It now accepts any PlayerIndex (no longer hard coded to just PlayerIndex.One) and it no longer uses a MessageBox to get the users selection. The code has also been modified so that it works both for the 360 and for the PC. Check out “Tell me what’s wrong!” and let me know if you have any thoughts or suggestions. I really do appreciate the feedback.

  • Back-sliding into Unmanaged Code

    - by Laila
    It is difficult to write about Microsoft's ambivalence to .NET without mentioning clichés about dog food.  In case you've been away a long time, you'll remember that Microsoft surprised everyone with the speed and energy with which it introduced and evangelised the .NET Framework for managed code. There was good reason for this. Once it became obvious to all that it had sleepwalked into third place as a provider of development languages, behind Borland and Sun, it reacted quickly to attract the best talent in the industry to produce a windows version of the Java runtime, with Bounds-checking, Automatic Garbage collection, structures exception handling and common data types. To develop applications for this managed runtime, it produced several excellent languages, and more are being provided. The only thing Microsoft ever got wrong was to give it a stupid name. The logical step for Microsoft would be to base the entire operating system on the .NET framework, and to re-engineer its own applications. In 2002, Bill Gates, then Microsoft Chairman and Chief Software Architect said about their plans for .NET, "This is a long-term approach. These things don't happen overnight." Now, eight years later, we're still waiting for signs of the 'long-term approach'. Microsoft's vision of an entirely managed operating system has subsided since the Vista fiasco, but stays alive yet dormant as Midori, still being developed by Microsoft Research. This is an Internet-centric fork of the singularity operating system, a research project started in 2003 to build a highly-dependable operating system in which the kernel, device drivers, and applications are all written in managed code. Midori is predicated on the prevalence of connected systems, with provisions for distributed concurrency where application components exist 'in the cloud', and supports a programming model that can tolerate cancellation, intermittent connectivity and latency. It features an entirely new security model that sandboxes applications for increased security. So have Microsoft converted its existing applications to the .NET framework? It seems not. What Windows applications can run on Mono? Very few, it seems. We all thought that .NET spelt the end of DLL Hell and the need for COM interop, but it looks as if Bill Gates' idea of 'not overnight' might stretch to a decade or more. The Operating System has shown only minimal signs of migrating to .NET. Even where the use of .NET has come to dominate, when used for server applications with IIS, IIS itself is still entirely developed in unmanaged code. This is an irritation to Microsoft's greatest supporters who committed themselves fully to the NET framework, only to find parts of the Ambivalent Microsoft Empire quietly backsliding into unmanaged code and the awful C++. It is a strategic mistake that the invigorated Apple didn't make with the Mac OS X Architecture. Cheers, Laila

  • how can I stop my sonicwall TZ-210 (SonicOS Enhanced 5.5.1.0-5o) from responding to arp queries on the wan subnet?

    - by IsaacB
    My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway. How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately. What can I do? Any suggestions?

  • Multiple WAN interfaces in same subnet on Sonicwall NSA220?

    - by Ttamsen
    (eta salutation, which keeps getting eaten.) Hi, all. I see a bunch of related questions, so I'm hesitant to ask, but: I have a situation where I have a Sonicwall NSA220 serving as firewall/router for two internal subnets to two external WAN connections. In some locations this is two separate ISPs. In others, it's the same ISP but with multiple circuits. The problem is that one ISP has been unable to provide unique subnets for each WAN interface. Is there any possibility that I might be able to bond the two WAN interfaces into a single virtual interface, and then use source-routing to get internal subnets communicating out the appropriate physical interface? Or even just use traffic-shaping to give each internal network appropriate shared bandwidth? I haven't found anything in the docs, but it seemed like it might be worth asking. Thanks for any help! -Steve.

  • Windows Server - Dual NIC Bandwidth Pooling

    - by tsilb
    I have a Windows Server 2008 machine with dual NICs. Both are plugged into the same switch in a typical one-switch, one-gateway home network. This server is used almost exclusively for inbound connections. It hosts a web server (IIS 6), SQL server, and file server (via LAN UNC paths and mapped drives). How do I make best use of inbound bandwidth across both NICs? For example, if I connect to it by hostname and one of the interfaces has high traffic, I'd like the new connection to use the other interface.

  • How to have file/folder icons use a relative path?

    - by Memor-X
    On my portable hard drive I set icons for almost every organized folder. All these icons are located in an Icons folder located on the root directory of the same hard drive. When I change the drive letter of the hard drive (well I don't, windows does automatically sometimes) these icons are lost. So far this hard drive is assigned to F: While it's not a problem now, it may becomes a problem if I upgrade my computer or get a new one and the F: Drive is already taken up for something else. It's also annoying on networks where F: is mapped to a network drive.

  • Joining an Active Directory domain using netdom

    - by Cheezo
    I have a simple script to join an AD domain and rename the computer. When I execute these commands directly on the CLI, it works fine. When I execute the same via batch file, I get an error saying The network path was not found I am running as Administrator with full privileges. I have googled around microsoft forums but my case is unique because it works from the CLI and not from the batch file netdom join %%computername%% /domain:OPSCODEDEMO.COM /userd:Administrator /passwordd:xxx netdom renamecomputer %%computername%% /NewName:%hostname% /Force The environment is Windows 2k8 R2 SP1 running on Ninefold Cloud (Xenserver).

  • Fedora 17 - Can't access remote machine using hostname

    - by Aaron
    I am using Fedora 17 and am trying to access a remote machine (running Fedora 15) using its hostname which isn't working. The machine is right next to me on the same switch as my machine (so they are both on the same network with the same subnet and everything). When I was running Windows (7 32-bit) on my machine I could access the other machine no problem but now that I am running Fedora 17 that's not the case. Is there an additional daemon or something that I need to be using in order for this to work?

  • cannot move file: "file cannot be found" (Windows XP)

    - by Steve
    I have some CR2 files in a subfolder of My Documents called My Photos on a Windows XP PC. I want to move them across a WIFI network to an external HDD attached to a Windows 7 PC. I have read/write permissions on the external HDD, as I mapped to this HDD using the Windows 7 user account. When I try to move a single CR2 file, I receive "Cannot copy IMG_3317: Cannot find the specified file. Make sure you specify the correct path and file name." If I refresh the source folder, the file is still there. It is not read only, and I have read/write access to the source file. I can view its properties. Why can't I move this file? I have been able to move similar files in the past.

  • Getting into driver development for linux [closed]

    - by user1103966
    Right now, I've been learning about writing device-drivers for linux 3.2 kernel for about 2 months. So far I have been able program simple char drivers that only read and write to a fictitious dev structure like a file, but now I'm moving to more advance concepts. The new material I've learned about includes I/O port manipulation, memory management, and interrupts. I feel that I have a basic understanding of overall driver operation but, there is still so much that I don't know. My question is this, given that I have the basic theory of how to write a dev-driver for a piece of hardware ... how long would it take to actually develop the skills of writing actual software that companies would want to employ? I plan on getting involved in an open-source project and building a portfolio. Also what type of beginner drivers could I write for hardware that would best help me develop my skills? I was thinking that taking on a project where I design my own key logger would easy and a good assignment to help me understand how IO ports and interrupts are used. I may want to eventually specialize in writing software for video cards or network devices though these devices seem beyond my understanding at the moment. Thanks for any help

  • Consequences of changing a password in Windows

    - by Borek
    I'm having 2 machines on my home network where I have the same account name but different passwords. I believe there should be advantages to having a single one (I hope :) but also think that changing it on one of the machines will do something - I'm just not sure what exactly. Will my stored passwords in IE and Chrome still work? Scheduled tasks? Etc. I'm looking for a list of things that I should watch out for after I change the user password.

    I have the MD of a client of ours who has a Windows 7 Profile that is currently 14GB thanks to Videos/Music and Documents. The first thing we did was to switch from roaming to local. What I need to know is now the profile is local am I wasting my time by reducing it any further? Does it really make a difference to performance having a large local user profile? Only the 4GB outlook ost that talks to the network frequently. Thanks in advance.... Richard

  • Filemaker 10 Advanced sending email via script & SMTP

    - by Sean
    We are using a windows server box to run the databases but we have found via the headers that the emails are send from the local workstation. We have moved to a new email system and have set up a local linux server to securely send email out of our network to devices that do not support new protocols and encryption. But once we set up the script in filemaker 10 advanced (the local machine os x) we set it to the ip of our local box with no authentication but it does not send out an email. It creates a connection we see in the logs on the linux box but nothing more, additionally you can start a telnet connection with no issues. We have also made sure that there are no additional issue that we can see in our firewall policies. Any ideas where we should start? Does Filemaker 10 advanced log errors anywhere because I could not find any log files.

  • Tömörítés becslése - Compression Advisor

    - by lsarecz
    Az Oracle Database 11g verziójától már OLTP adatbázisok is hatékonyan tömöríthetok az Advanced Compression funkcióval. Nem csak a tárolandó adatok mennyisége csökken ezáltal felére, vagy akár negyedére, de az adatbázis teljesítménye is javulhat, amennyiben I/O korlátos a rendszer (és általában az). Hogy pontosan mekkora tömörítés várható az Advanced Compression bevezetésével, az kiválóan becsülheto a Compression Advisor eszközzel. Ez nem csak az OLTP tömörítés mértékét, de 11gR2 verziótól kezdve a HCC tömörítés arányát is becsülni tudja, amely Exadata Database Machine, Pillar Axiom illetve ZFS Storage alkalmazásával érheto el. A HCC tömörítés becsléséhez csak 11gR2 adatbázisra van szükség, nem kell hozzá a speciális célhardver (Exadata, Pillar, ZFS). A Compression Advisor valójában a DBMS_COMPRESSION package használatával érheto el. A package-hez tartozik 6 konstans, amellyel a kívánt tömörítési szintek választhatók ki: Constant Type Value Description COMP_NOCOMPRESS NUMBER 1 No compression COMP_FOR_OLTP NUMBER 2 OLTP compression COMP_FOR_QUERY_HIGH NUMBER 4 High compression level for query operations COMP_FOR_QUERY_LOW NUMBER 8 Low compression level for query operations COMP_FOR_ARCHIVE_HIGH NUMBER 16 High compression level for archive operations COMP_FOR_ARCHIVE_LOW NUMBER 32 Low compression level for archive operations A GET_COMPRESSION_RATIO tárolt eljárás elemzi a tömöríteni kívánt táblát. Mindig csak egy táblát, vagy opcionálisan annak egy partícióját tudja elemezni úgy, hogy a tábláról készít egy másolatot egy külön erre a célra kijelölt/létrehozott táblatérre. Amennyiben az elemzést egyszerre több tömörítési szintre futtatjuk, úgy a tábláról annyi másolatot készít. A jó közelítésu becslés (+-5%) feltétele, hogy táblánként/partíciónként minimum 1 millió sor legyen. 11gR1 esetében még a DBMS_COMP_ADVISOR csomag GET_RATIO eljárása volt használatos, de ez még nem támogatta a HCC becslést. Érdemes még megnézni és kipróbálni a Tyler Muth blogjában publikált formázó eszközt, amivel a compression advisor kimenete alakítható jól értelmezheto formátumúvá. Végül összegezném mit is tartalmaz az Advanced Compression opció, mivel gyakran nem világos a felhasználóknak miért kell fizetni: Data Guard Network Compression Data Pump Compression (COMPRESSION=METADATA_ONLY does not require the Advanced Compression option) Multiple RMAN Compression Levels (RMAN DEFAULT COMPRESS does not require the Advanced Compression option) OLTP Table Compression SecureFiles Compression and Deduplication Ez alapján RMAN esetében például a default compression (BZIP2) szint ingyen használható, viszont az új ZLIB Advanced Compression opciót igényel. A ZLIB hatékonyabban használja a CPU-t, azaz jóval gyorsabb, viszont kisebb tömörítési arány érheto el vele.

  • What's the most efficient method for moving and transcoding HD video from my Tivo to iTunes on OS X

    - by Bryan Schuetz
    I've got a Tivo with some HD recordings on it. I'd like to move those files over to my Mac and add them into iTunes. I'd like the move and transcoding to be as painless as possible, and I'd like to preserve the quality of the original HD recording. I've got a network connection to the Tivo and can move the files over but the real problem seems to be transcoding. I tried using MEncoder to transcode to H.264 but the quality really suffered. I was doing the conversion at 10mbps so I'm not sure why the quality was so bad, lots of artifacting, etc.

  • Windows 2008 DHCP service fails - "...failed to see a directory server for authorization."

    - by ewwhite
    I have a small environment running Windows 2008 R2 where the DHCP service on the domain controller fails every two weeks. The most-visible error is Event ID 1059 and the Event Viewer message is: "The DHCP service failed to see a directory server for authorization." The setup features two domain controller and the usual services and roles (file, print, Exchange). Restarting the service fails for a variety of reasons. I've had the following messages at different times: "Not enough storage is available to complete this operation". "Unable to determine the DHCP Server version for the Server 192.168.x.x" "The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service." A reboot of the domain controller resolves the issue for ~2 weeks. The systems are virtualized and there are no network connectivity issues. Any ideas what's happening here?

  • On a Mac, how are connections (possibly by spyware) made to outside internet addresses during initia

    - by TT
    I am trying to secure a Mac after discovering that network links are being established to some unwanted internet sites. Using 'lsof -i' (list open 'files', internet) I have seen that launchd, ntpd, firefox, dropbox and other processes are either 'LISTENING' or have 'ESTABLISHED' links to a site or sites which I suspect have to do with spyware. I have been trying to find startup files and preference lists that initiate thise links but can't find them. I could easily reinstall the OS and restore data from a backup but I'd prefer to know how to fix this as I have six Macs to look after. Thanks...
