  • Err Web Service?

    - by j-t-s
    Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

  • Why Can't I import a UITableViewCell subclass ? That's weird....

    - by user320064
    It's like this, I created a UITableViewCell subclass called NewsItemCell, then I wanna use it in my FirstViewController.m, then I tried to import it, but the compiler keeps telling me this Below is my code, it is driving me mad, thank you if you can help. import "NewsItemCell.h" import "FirstViewController.h" @implementation FirstViewController @synthesize computers; (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"NewsItemCellIdentifier"; NewsItemcell *cell = (NewsItemcell *)[tableView dequeueReusableCellWithIdentifier: CellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"NewsItemCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[NewsItemcell class]]) cell = (NewsItemcell *)oneObject; } NSUInteger row = [indexPath row]; NSDictionary *rowData = [self.computers objectAtIndex:row]; cell.newsTitle.text = [rowData objectForKey:@"Color"]; cell.newsDate.text = [rowData objectForKey:@"Name"]; return cell; } Jason

  • How to display more things in admin.StackedInline

    - by FurtiveFelon
    Hi all, I have Article model and a Comment model. Comment is created in admin.py as admin.StackedInline, and it has several fields, notably content and lastUpdate. For lastUpdate, i have specified as follows: lastUpdate = models.DateTimeField('last update', auto_now=True). Understandably, lastUpdate is not displayed when i try to add new comment (or edit old ones). However, i would like it to display for older comments if possible, as a read only thing. Is there anyway of accomplishing that? Thanks a lot! Jason

  • jQuery FadeTo() bg on rollover, IMG animate().width height

    - by jg462095
    Hello all, I have been reading StackOverflow for a while and now I have a question I cannot find an answer to. i am trying to fade a background and increase on img size on rollover. I have tried animate() and fadeTo(), however, the entire div fades. Do I need to absolute position my images over the div and not within it? img or img? Is that the only way to get items within a div to not fade along with the background? Thanks! Jason

  • How can I set breakpoints in an external JS script in Firebug

    - by Manu
    I can easily set breakpoints in embedded JS functions, but I don't see any way of accessing extarnal JS scripts via Firebug unless I happen to enter them during a debug session. Is there a way to do this w/o having to 'explore' my way into the script? @Jason: This is a good point, but in my case I do not have easy access to the script. I am specifically talking about the client scripts which are invoked by the ASP.Net Validators that I would like to debug. I can access them during a debug session through entering the function calls, but I could not find a way to access them directly.

  • what's the best (most effecient) way in asp .net to return a whole page into tabbed content?

    - by ijjo
    what i want to do is every time i click on a tab, the content area is replaced by pretty much a whole new page. i don't want a full page load so i want to do it in ajax, but i'm used to sending back small jason data via page methods. i'm not sure how i would construct a whole new page and return that via ajax and i would like to simply assign the whole content returned to a div and be done with it. what's the best way to do this with the least amount of overhead (i know there are some inefficient ways the scriptmanager does ajax)? or is it better to load the tabbed content in an iframe? fyi i'm already using jquery to call lightweight pagemethods on my asp net page and that works great.

  • Information stored in a cookie file

    - by jklmuk
    Thanks for you help in advance. I am trying to figure out the structure of the cookie file, more specifically i want to be able to determine the expiry time. From the cookies i have created they all appear to be in a standard format. Name, Value, website,followed by 5 numbers and a star. See example below. name value www.website.co.uk/ 1536 3041141504 30135951 1632526096 30135949 * Obviously the expiry time is one of the numbers, the question is which one. From experiments I have determined that the first and fifth number don't seem to change. In a case where i generated three cookies at the same time with a 1000 second time difference i noticed that the fourth number appeared to increase by 2000 suggesting that this has a connection with the expiry time. Can anyone confirm if i am heading in the right direction? And does any one know how i convert this to a human time and date(preferably in php but any language would give me a starting point) thanks Jason

  • Best video codec to store my own collection

    - by Jack
    Hello! I think this question has already been asked but with different flavours. My problem resised in the fact that my camera (Canon G9) creates video with almost raw codec (I think it's plain old MPEG) so a 10 minutes video is almost 900mb. I would like to convert them in a format that has a good trade-off between space and quality, but I would prefer having the quality as good as the original (of course this is not possible because of lossy compression) just saving as much space is possible with a minimal lose of quality. Which codec should I look for? H264? It seems to be the champion of the moment.. otherwise which other ones could I try? XviD? Which parameters should I use? I mean how many kbits/s is a fair good bitrate to keep high quality? And what about audio codec? video specs are 640x480 at 30fps or 1024x768 at 15fps.. thanks in advance!

  • Toorcon14

    - by danx
    Toorcon 2012 Information Security Conference San Diego, CA, http://www.toorcon.org/ Dan Anderson, October 2012 It's almost Halloween, and we all know what that means—yes, of course, it's time for another Toorcon Conference! Toorcon is an annual conference for people interested in computer security. This includes the whole range of hackers, computer hobbyists, professionals, security consultants, press, law enforcement, prosecutors, FBI, etc. We're at Toorcon 14—see earlier blogs for some of the previous Toorcon's I've attended (back to 2003). This year's "con" was held at the Westin on Broadway in downtown San Diego, California. The following are not necessarily my views—I'm just the messenger—although I could have misquoted or misparaphrased the speakers. Also, I only reviewed some of the talks, below, which I attended and interested me. MalAndroid—the Crux of Android Infections, Aditya K. Sood Programming Weird Machines with ELF Metadata, Rebecca "bx" Shapiro Privacy at the Handset: New FCC Rules?, Valkyrie Hacking Measured Boot and UEFI, Dan Griffin You Can't Buy Security: Building the Open Source InfoSec Program, Boris Sverdlik What Journalists Want: The Investigative Reporters' Perspective on Hacking, Dave Maas & Jason Leopold Accessibility and Security, Anna Shubina Stop Patching, for Stronger PCI Compliance, Adam Brand McAfee Secure & Trustmarks — a Hacker's Best Friend, Jay James & Shane MacDougall MalAndroid—the Crux of Android Infections Aditya K. Sood, IOActive, Michigan State PhD candidate Aditya talked about Android smartphone malware. There's a lot of old Android software out there—over 50% Gingerbread (2.3.x)—and most have unpatched vulnerabilities. Of 9 Android vulnerabilities, 8 have known exploits (such as the old Gingerbread Global Object Table exploit). Android protection includes sandboxing, security scanner, app permissions, and screened Android app market. The Android permission checker has fine-grain resource control, policy enforcement. Android static analysis also includes a static analysis app checker (bouncer), and a vulnerablity checker. What security problems does Android have? User-centric security, which depends on the user to grant permission and make smart decisions. But users don't care or think about malware (the're not aware, not paranoid). All they want is functionality, extensibility, mobility Android had no "proper" encryption before Android 3.0 No built-in protection against social engineering and web tricks Alternative Android app markets are unsafe. Simply visiting some markets can infect Android Aditya classified Android Malware types as: Type A—Apps. These interact with the Android app framework. For example, a fake Netflix app. Or Android Gold Dream (game), which uploads user files stealthy manner to a remote location. Type K—Kernel. Exploits underlying Linux libraries or kernel Type H—Hybrid. These use multiple layers (app framework, libraries, kernel). These are most commonly used by Android botnets, which are popular with Chinese botnet authors What are the threats from Android malware? These incude leak info (contacts), banking fraud, corporate network attacks, malware advertising, malware "Hackivism" (the promotion of social causes. For example, promiting specific leaders of the Tunisian or Iranian revolutions. Android malware is frequently "masquerated". That is, repackaged inside a legit app with malware. To avoid detection, the hidden malware is not unwrapped until runtime. The malware payload can be hidden in, for example, PNG files. Less common are Android bootkits—there's not many around. What they do is hijack the Android init framework—alteering system programs and daemons, then deletes itself. For example, the DKF Bootkit (China). Android App Problems: no code signing! all self-signed native code execution permission sandbox — all or none alternate market places no robust Android malware detection at network level delayed patch process Programming Weird Machines with ELF Metadata Rebecca "bx" Shapiro, Dartmouth College, NH https://github.com/bx/elf-bf-tools @bxsays on twitter Definitions. "ELF" is an executable file format used in linking and loading executables (on UNIX/Linux-class machines). "Weird machine" uses undocumented computation sources (I think of them as unintended virtual machines). Some examples of "weird machines" are those that: return to weird location, does SQL injection, corrupts the heap. Bx then talked about using ELF metadata as (an uintended) "weird machine". Some ELF background: A compiler takes source code and generates a ELF object file (hello.o). A static linker makes an ELF executable from the object file. A runtime linker and loader takes ELF executable and loads and relocates it in memory. The ELF file has symbols to relocate functions and variables. ELF has two relocation tables—one at link time and another one at loading time: .rela.dyn (link time) and .dynsym (dynamic table). GOT: Global Offset Table of addresses for dynamically-linked functions. PLT: Procedure Linkage Tables—works with GOT. The memory layout of a process (not the ELF file) is, in order: program (+ heap), dynamic libraries, libc, ld.so, stack (which includes the dynamic table loaded into memory) For ELF, the "weird machine" is found and exploited in the loader. ELF can be crafted for executing viruses, by tricking runtime into executing interpreted "code" in the ELF symbol table. One can inject parasitic "code" without modifying the actual ELF code portions. Think of the ELF symbol table as an "assembly language" interpreter. It has these elements: instructions: Add, move, jump if not 0 (jnz) Think of symbol table entries as "registers" symbol table value is "contents" immediate values are constants direct values are addresses (e.g., 0xdeadbeef) move instruction: is a relocation table entry add instruction: relocation table "addend" entry jnz instruction: takes multiple relocation table entries The ELF weird machine exploits the loader by relocating relocation table entries. The loader will go on forever until told to stop. It stores state on stack at "end" and uses IFUNC table entries (containing function pointer address). The ELF weird machine, called "Brainfu*k" (BF) has: 8 instructions: pointer inc, dec, inc indirect, dec indirect, jump forward, jump backward, print. Three registers - 3 registers Bx showed example BF source code that implemented a Turing machine printing "hello, world". More interesting was the next demo, where bx modified ping. Ping runs suid as root, but quickly drops privilege. BF modified the loader to disable the library function call dropping privilege, so it remained as root. Then BF modified the ping -t argument to execute the -t filename as root. It's best to show what this modified ping does with an example: $ whoami bx $ ping localhost -t backdoor.sh # executes backdoor $ whoami root $ The modified code increased from 285948 bytes to 290209 bytes. A BF tool compiles "executable" by modifying the symbol table in an existing ELF executable. The tool modifies .dynsym and .rela.dyn table, but not code or data. Privacy at the Handset: New FCC Rules? "Valkyrie" (Christie Dudley, Santa Clara Law JD candidate) Valkyrie talked about mobile handset privacy. Some background: Senator Franken (also a comedian) became alarmed about CarrierIQ, where the carriers track their customers. Franken asked the FCC to find out what obligations carriers think they have to protect privacy. The carriers' response was that they are doing just fine with self-regulation—no worries! Carriers need to collect data, such as missed calls, to maintain network quality. But carriers also sell data for marketing. Verizon sells customer data and enables this with a narrow privacy policy (only 1 month to opt out, with difficulties). The data sold is not individually identifiable and is aggregated. But Verizon recommends, as an aggregation workaround to "recollate" data to other databases to identify customers indirectly. The FCC has regulated telephone privacy since 1934 and mobile network privacy since 2007. Also, the carriers say mobile phone privacy is a FTC responsibility (not FCC). FTC is trying to improve mobile app privacy, but FTC has no authority over carrier / customer relationships. As a side note, Apple iPhones are unique as carriers have extra control over iPhones they don't have with other smartphones. As a result iPhones may be more regulated. Who are the consumer advocates? Everyone knows EFF, but EPIC (Electrnic Privacy Info Center), although more obsecure, is more relevant. What to do? Carriers must be accountable. Opt-in and opt-out at any time. Carriers need incentive to grant users control for those who want it, by holding them liable and responsible for breeches on their clock. Location information should be added current CPNI privacy protection, and require "Pen/trap" judicial order to obtain (and would still be a lower standard than 4th Amendment). Politics are on a pro-privacy swing now, with many senators and the Whitehouse. There will probably be new regulation soon, and enforcement will be a problem, but consumers will still have some benefit. Hacking Measured Boot and UEFI Dan Griffin, JWSecure, Inc., Seattle, @JWSdan Dan talked about hacking measured UEFI boot. First some terms: UEFI is a boot technology that is replacing BIOS (has whitelisting and blacklisting). UEFI protects devices against rootkits. TPM - hardware security device to store hashs and hardware-protected keys "secure boot" can control at firmware level what boot images can boot "measured boot" OS feature that tracks hashes (from BIOS, boot loader, krnel, early drivers). "remote attestation" allows remote validation and control based on policy on a remote attestation server. Microsoft pushing TPM (Windows 8 required), but Google is not. Intel TianoCore is the only open source for UEFI. Dan has Measured Boot Tool at http://mbt.codeplex.com/ with a demo where you can also view TPM data. TPM support already on enterprise-class machines. UEFI Weaknesses. UEFI toolkits are evolving rapidly, but UEFI has weaknesses: assume user is an ally trust TPM implicitly, and attached to computer hibernate file is unprotected (disk encryption protects against this) protection migrating from hardware to firmware delays in patching and whitelist updates will UEFI really be adopted by the mainstream (smartphone hardware support, bank support, apathetic consumer support) You Can't Buy Security: Building the Open Source InfoSec Program Boris Sverdlik, ISDPodcast.com co-host Boris talked about problems typical with current security audits. "IT Security" is an oxymoron—IT exists to enable buiness, uptime, utilization, reporting, but don't care about security—IT has conflict of interest. There's no Magic Bullet ("blinky box"), no one-size-fits-all solution (e.g., Intrusion Detection Systems (IDSs)). Regulations don't make you secure. The cloud is not secure (because of shared data and admin access). Defense and pen testing is not sexy. Auditors are not solution (security not a checklist)—what's needed is experience and adaptability—need soft skills. Step 1: First thing is to Google and learn the company end-to-end before you start. Get to know the management team (not IT team), meet as many people as you can. Don't use arbitrary values such as CISSP scores. Quantitive risk assessment is a myth (e.g. AV*EF-SLE). Learn different Business Units, legal/regulatory obligations, learn the business and where the money is made, verify company is protected from script kiddies (easy), learn sensitive information (IP, internal use only), and start with low-hanging fruit (customer service reps and social engineering). Step 2: Policies. Keep policies short and relevant. Generic SANS "security" boilerplate policies don't make sense and are not followed. Focus on acceptable use, data usage, communications, physical security. Step 3: Implementation: keep it simple stupid. Open source, although useful, is not free (implementation cost). Access controls with authentication & authorization for local and remote access. MS Windows has it, otherwise use OpenLDAP, OpenIAM, etc. Application security Everyone tries to reinvent the wheel—use existing static analysis tools. Review high-risk apps and major revisions. Don't run different risk level apps on same system. Assume host/client compromised and use app-level security control. Network security VLAN != segregated because there's too many workarounds. Use explicit firwall rules, active and passive network monitoring (snort is free), disallow end user access to production environment, have a proxy instead of direct Internet access. Also, SSL certificates are not good two-factor auth and SSL does not mean "safe." Operational Controls Have change, patch, asset, & vulnerability management (OSSI is free). For change management, always review code before pushing to production For logging, have centralized security logging for business-critical systems, separate security logging from administrative/IT logging, and lock down log (as it has everything). Monitor with OSSIM (open source). Use intrusion detection, but not just to fulfill a checkbox: build rules from a whitelist perspective (snort). OSSEC has 95% of what you need. Vulnerability management is a QA function when done right: OpenVas and Seccubus are free. Security awareness The reality is users will always click everything. Build real awareness, not compliance driven checkbox, and have it integrated into the culture. Pen test by crowd sourcing—test with logging COSSP http://www.cossp.org/ - Comprehensive Open Source Security Project What Journalists Want: The Investigative Reporters' Perspective on Hacking Dave Maas, San Diego CityBeat Jason Leopold, Truthout.org The difference between hackers and investigative journalists: For hackers, the motivation varies, but method is same, technological specialties. For investigative journalists, it's about one thing—The Story, and they need broad info-gathering skills. J-School in 60 Seconds: Generic formula: Person or issue of pubic interest, new info, or angle. Generic criteria: proximity, prominence, timeliness, human interest, oddity, or consequence. Media awareness of hackers and trends: journalists becoming extremely aware of hackers with congressional debates (privacy, data breaches), demand for data-mining Journalists, use of coding and web development for Journalists, and Journalists busted for hacking (Murdock). Info gathering by investigative journalists include Public records laws. Federal Freedom of Information Act (FOIA) is good, but slow. California Public Records Act is a lot stronger. FOIA takes forever because of foot-dragging—it helps to be specific. Often need to sue (especially FBI). CPRA is faster, and requests can be vague. Dumps and leaks (a la Wikileaks) Journalists want: leads, protecting ourselves, our sources, and adapting tools for news gathering (Google hacking). Anonomity is important to whistleblowers. They want no digital footprint left behind (e.g., email, web log). They don't trust encryption, want to feel safe and secure. Whistleblower laws are very weak—there's no upside for whistleblowers—they have to be very passionate to do it. Accessibility and Security or: How I Learned to Stop Worrying and Love the Halting Problem Anna Shubina, Dartmouth College Anna talked about how accessibility and security are related. Accessibility of digital content (not real world accessibility). mostly refers to blind users and screenreaders, for our purpose. Accessibility is about parsing documents, as are many security issues. "Rich" executable content causes accessibility to fail, and often causes security to fail. For example MS Word has executable format—it's not a document exchange format—more dangerous than PDF or HTML. Accessibility is often the first and maybe only sanity check with parsing. They have no choice because someone may want to read what you write. Google, for example, is very particular about web browser you use and are bad at supporting other browsers. Uses JavaScript instead of links, often requiring mouseover to display content. PDF is a security nightmare. Executible format, embedded flash, JavaScript, etc. 15 million lines of code. Google Chrome doesn't handle PDF correctly, causing several security bugs. PDF has an accessibility checker and PDF tagging, to help with accessibility. But no PDF checker checks for incorrect tags, untagged content, or validates lists or tables. None check executable content at all. The "Halting Problem" is: can one decide whether a program will ever stop? The answer, in general, is no (Rice's theorem). The same holds true for accessibility checkers. Language-theoretic Security says complicated data formats are hard to parse and cannot be solved due to the Halting Problem. W3C Web Accessibility Guidelines: "Perceivable, Operable, Understandable, Robust" Not much help though, except for "Robust", but here's some gems: * all information should be parsable (paraphrasing) * if not parsable, cannot be converted to alternate formats * maximize compatibility in new document formats Executible webpages are bad for security and accessibility. They say it's for a better web experience. But is it necessary to stuff web pages with JavaScript for a better experience? A good example is The Drudge Report—it has hand-written HTML with no JavaScript, yet drives a lot of web traffic due to good content. A bad example is Google News—hidden scrollbars, guessing user input. Solutions: Accessibility and security problems come from same source Expose "better user experience" myth Keep your corner of Internet parsable Remember "Halting Problem"—recognize false solutions (checking and verifying tools) Stop Patching, for Stronger PCI Compliance Adam Brand, protiviti @adamrbrand, http://www.picfun.com/ Adam talked about PCI compliance for retail sales. Take an example: for PCI compliance, 50% of Brian's time (a IT guy), 960 hours/year was spent patching POSs in 850 restaurants. Often applying some patches make no sense (like fixing a browser vulnerability on a server). "Scanner worship" is overuse of vulnerability scanners—it gives a warm and fuzzy and it's simple (red or green results—fix reds). Scanners give a false sense of security. In reality, breeches from missing patches are uncommon—more common problems are: default passwords, cleartext authentication, misconfiguration (firewall ports open). Patching Myths: Myth 1: install within 30 days of patch release (but PCI §6.1 allows a "risk-based approach" instead). Myth 2: vendor decides what's critical (also PCI §6.1). But §6.2 requires user ranking of vulnerabilities instead. Myth 3: scan and rescan until it passes. But PCI §11.2.1b says this applies only to high-risk vulnerabilities. Adam says good recommendations come from NIST 800-40. Instead use sane patching and focus on what's really important. From NIST 800-40: Proactive: Use a proactive vulnerability management process: use change control, configuration management, monitor file integrity. Monitor: start with NVD and other vulnerability alerts, not scanner results. Evaluate: public-facing system? workstation? internal server? (risk rank) Decide:on action and timeline Test: pre-test patches (stability, functionality, rollback) for change control Install: notify, change control, tickets McAfee Secure & Trustmarks — a Hacker's Best Friend Jay James, Shane MacDougall, Tactical Intelligence Inc., Canada "McAfee Secure Trustmark" is a website seal marketed by McAfee. A website gets this badge if they pass their remote scanning. The problem is a removal of trustmarks act as flags that you're vulnerable. Easy to view status change by viewing McAfee list on website or on Google. "Secure TrustGuard" is similar to McAfee. Jay and Shane wrote Perl scripts to gather sites from McAfee and search engines. If their certification image changes to a 1x1 pixel image, then they are longer certified. Their scripts take deltas of scans to see what changed daily. The bottom line is change in TrustGuard status is a flag for hackers to attack your site. Entire idea of seals is silly—you're raising a flag saying if you're vulnerable.

  • Summit Old, Summit New, Summit Borrowed...

    - by Rob Farley
    PASS Summit is coming up, and I thought I’d post a few things. Summit Old... At the PASS Summit, you will get the chance to hear presentations by the SQL Server establishment. Just about every big name in the SQL Server world is a regular at the PASS Summit, so you will get to hear and meet people like Kalen Delaney (@sqlqueen) (who just recently got awarded MVP status for the 20th year running), and from all around the world such as the UK’s Chris Webb (@technitrain) or Pinal Dave (@pinaldave) from India. Almost all the household names in SQL Server will be there, including a large contingent from Microsoft. The PASS Summit is by far the best place to meet the legends of SQL Server. And they’re not all old. Some are, but most of them are younger than you might think. ...Summit New... The hottest topics are often about the newest technologies (such as SQL Server 2012). But you will almost certainly learn new stuff about older versions too. But that’s not what I wanted to pick on for this point. There are many new speakers at every PASS Summit, and content that has not been covered in other places. This year, for example, LobsterPot’s Roger Noble (@roger_noble) is giving a presentation for the first time. He’s a regular around the Australian circuit, but this is his first time presenting to a US audience. New Zealand’s Paul White (@sql_kiwi) is attending his first PASS Summit, and will be giving over four hours of incredibly deep stuff that has never been presented anywhere in the US before (I can’t say the world, because he did present similar material in Adelaide earlier in the year). ...Summit Borrowed... No, I’m not talking about plagiarism – the talks you’ll hear are all their own work. But you will get a lot of stuff you’ll be able to take back and apply at work. The PASS Summit sessions are not full of sales-pitches, telling you about how great things could be if only you’d buy some third-party vendor product. It’s simply not that kind of conference, and PASS doesn’t allow that kind of talk to take place. Instead, you’ll be taught techniques, and be able to download scripts and slides to let you perform that magic back at work when you get home. You will definitely find plenty of ideas to borrow at the PASS Summit. ...Summit Blue Yeah – and there’s karaoke. Blue - Jason - SQL Karaoke - YouTube

  • SQL SERVER – BI Quiz Hint – Performance Tuning Cubes – Hints

    - by pinaldave
    I earlier wrote about SQL BI Quiz over here and here. The details of the quiz is here: Working with huge data is very common when it is about Data Warehousing. It is necessary to create Cubes on the data to make it meaningful and consumable. There are cases when retrieving the data from cube takes lots of the time. Let us assume that your cube is returning you data very quickly. Suddenly on one day it is returning the data very slowly. What are the three things will you to diagnose this. After diagnose what you will do to resolve performance issue. Participate in my question over here I required BI Expert Jason Thomas to help with few hints to blog readers. He is one of the leading SSAS expert and writes a complicated subject in simple words. If queries were executing properly before but now take a long time to return the data, it means that there has been a change in the environment in which it is running. Some possible changes are listed below:-  1) Data factors:- Compare the data size then and now. Increase in data can result in different execution times. Poorly written queries as well as poor design will not start showing issues till the data grows. How to find it out? (Ans : SQL Server profiler and Perfmon Counters can be used for identifying the issues and performance  tuning the MDX queries)  2) Internal Factors:- Is some slow MDX query / multiple mdx queries running at the same time, which was not running when you had tested it before? Is there any locking happening due to proactive caching or processing operations? Are the measure group caches being cleared by processing operations? (Ans : Again, profiler and perfmon counters will help in finding it out. Load testing can be done using AS Performance Workbench (http://asperfwb.codeplex.com/) by running multiple queries at once)  3) External factors:- Is some other application competing for the same resources?  HINT : Read “Identifying and Resolving MDX Query Performance Bottlenecks in SQL Server 2005 Analysis Services” (http://sqlcat.com/whitepapers/archive/2007/12/16/identifying-and-resolving-mdx-query-performance-bottlenecks-in-sql-server-2005-analysis-services.aspx) Well, these are great tips. Now win big prizes by participate in my question over here.

  • 24 Hours of PASS coming up soon!

    - by Rob Farley
    Massive thanks to all the people that have been shouting about this event already. I’ve seen quite a number of blog posts about it, and rather than listing some and missing others, please assume I’ve noticed your blog and accept my thanks. But in case this is all news to you – the next 24 Hours of PASS event is less than a fortnight away (Sep 20/21)! And there’s lots of info about it at http://www.sqlpass.org/24hours/fall2012/  (Don’t ask why it’s “Fall 2012”. Apparently that’s what this time of year is called in at least two countries. I would call it “Spring”, personally, but do appreciate that it’s “Autumn” in the Northern Hemisphere...) Yes, I blogged about it on the PASS blog a few weeks ago, but haven’t got around to writing about it here yet. As always, 24HOP is going to have some amazing content. But it’s going to be pointing at the larger event, which now less than two months away. That’s right, this 24HOP is the Summit 2012 Preview event. Most of the precon speakers are going to be represented, as are half-day session presenters, quite a few of the Spotlight presenters and some of the Microsoft speakers too. When you look down the list of sessions at http://www.sqlpass.org/24hours/fall2012/SessionsbySchedule.aspx, you’ll find yourself wondering how you can fit them all in. Luckily, that’s not my problem. For me, it’s just about making sure that you can get to hear these people present, and get a taste for the amazing time that you’ll have if you can come to the Summit. I see this 24HOP as the kind of thing that will just drive you crazy if you can’t get to the Summit. There will be so much great content, and every one of these presenters will be delivering even more than this at the Summit itself. If you tune into Jason Strate’s 24HOP session on the Plan Cache and are impressed – well, you can get to a longer session by him on that same topic at the Summit. And the same goes for all of them. If you’re anything like me, you’ll find yourself looking at the Summit schedule, wishing you could get to several presentations for every time slot. So get yourself registered for 24HOP and help yourself make that decision. And if you can’t go to the Summit, tune in anyway. You’ll still learn a lot, and you might just be able to help persuade someone to send you to the Summit after all (before the price goes up after Sep 30).

  • Commerce, Anyway You Want It

    - by David Dorf
    I believe our industry is finally starting to realize the importance of letting consumers determine how, when, and where to interact with retailers.  Over the last few months I've seen several articles discussing the importance of removing the barriers between existing channels. Paula Rosenblum of RSR first brought the term omni-channel to my attention back in September. She stated, "omni-channel retail isn’t the merging of channels – rather, it’s the use of all possible channels (present and future) to enhance the customer experience in a profitable way." I added to her thoughts in this blog posting in which I said, "For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways." More recently Brian Walker of Gartner suggested we stop using the term multi-channel and begin thinking more about consumer touch-points. "It is time for organizations to leave their channel-oriented ways behind, and enter the era of agile commerce--optimizing their people, processes and technology to serve today's empowered, ever-connected customers across this rapidly evolving set of customer touch points." Now Jason Goldberg, better known as RetailGeek, says we should start breaking down the channel silos by re-casting the VP of E-Commerce as the VP of Digital Marketing, and change his/her focus to driving sales across all channels using digital media. This logic is based on the fact that consumers switch between channels, or touch-points as Brian prefers, as part of their larger buying process. Today's smart consumer leverages the Web, mobile, and stores to provide the best shopping experience, so retailers need to make this easier. Regardless of what we call it, the key take-away is that "multi-channel" is not only an antiquated term but also an idea who's time has passed.  Today, retailers must look at e-commerce, m-commerce, f-commerce, catalogs, and traditional store sales collectively and through the consumers' eyes.  The goal is not to drive sales through each channel but rather to just drive sales -- using whatever method the customer prefers.  There really should be just one cart.

  • Using multiple diagrams per model in Entity Framework 5.0

    - by nikolaosk
    I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

  • Is there a pedagogical game engine?

    - by K.G.
    I'm looking for a book, website, or other resource that gives modern 3D game engines the same treatment as Operating Systems: Design and Implementation gave operating systems. I have read Jason Gregory's Game Engine Architecture, which I enjoyed. However, by intent the author treated components of the architecture as atomic units, whereas what I'm interested in is the plumbing between those units that makes a coherent whole out of ideally loosely coupled parts. In books such as these, one usually reads that "that's academic," but that's the point! I have also read Julian Gold's Object-oriented Game Development, which likewise was good, but I feel is beginning to show its age. Since even mobile platforms these days are multicore and have fast video memory, those kinds of things (concurrency, display item buffering) would ideally be covered. There are other resources, such as the Doom 3 source code, which is highly instructive for its being a shipped product. The problem with those is as follows: float Q_rsqrt( float number ) { long i; float x2, y; const float threehalfs = 1.5F; x2 = number * 0.5F; y = number; i = * ( long * ) &y; // evil floating point bit level hacking i = 0x5f3759df - ( i >> 1 ); // what the f***? y = * ( float * ) &i; y = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration // y = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed return y; } To wit, while brilliant, this kind of source requires more enlightenment than I can usually muster upon first read. In summary, here's my white whale: For an adult reader with experience in programming. I wish I could save all the trees killed by every. Single. Game Programming book ever devoting the first two chapters to "Now just what is a variable anyway?" In C or C++, very preferably C++. Languages that are more concise are fantastic for teaching, except for when what you want to learn is how to cope with a verbose language. There is also the benefit of the guardrails that C++ doesn't provide, such as garbage collection. Platform agnostic. I'm sincerely afraid that this book is out there and it's Visual C++/DirectX oriented. I'm a Linux guy, and I'd do what it takes, but I would very much like to be able to use OpenGL. Thanks for everything! Before anyone gets on my case about it, Fast inverse square root was from Quake III Arena, not Doom 3!

  • BizTalk MQSC adapter configuration error & IBM WebSphere MQ Client V6.0

    - by chinna
    Hi Guys, I'm having trouble configuring the MSQC adapter for BizTalk Server 2006. At the moment I'm getting the following error when setting up a receive location or send port: The adapter "MQSC" raised an error message. Details "The specified module could not be found. (Exception from HRESULT: 0x8007007E) A dependency could not be found. Refer to product documentation for information on MQSC Adapter software prerequisites.".For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I have installed the IBM WebSphere Client v6.0 installed but was unable to find the "IBM fix pack 6.0.1.1" for the WebSphere CLIENT as some people have suggested. I have found this post (http://www.biztalkgurus.com/forums/p/3719/7212.aspx) which seems to shed some light on this issue, but I am unable to find the fix-pack that they speak of or resolve the problem Is anybody able to provide any further information? A link to download the IBM WebSphere MQ Client V6.0 fix pack 6.0.1.1 would be a great start! Thanks, Jason

  • Exchange 2010: Replication Service Still Trying to Replicate Deleted Mailbox Store

    - by ThaKidd
    In advance, thank you for your opinions! I just migrated from Server/Exchange 2003 to Server 2008 SR2 running Exchange 2010. I had an extra mailbox that appeared with some system mailboxes in it. I used the EMS to move those mailboxes over and then deleted the store out of the EMC. Since then every so often I get an Error in Event Viewer. Source: MSExchangeRepl ID: 4098 Error: The Microsoft Exchange Replication service couldn't find a valid configuration for database '5f012f40-3bad-4003-a373-dbc0ffb6736f' on server 'EXCHSERVER'. Error: (nothing after this) I can confirm that the above GUID is the mailbox store of that I deleted. No other Exchange errors occur. How can I tell Exchange Replication to ignore this store? Setup, one Exchange server 2003 transitioned over to 2010. No other Exchange servers. Is there a way to fix this? Do I need to change a setting to stop replication? I plan to add a second Exchange server in the next few days so stopping replication would be a bad thing. Thanks again in advance. Jason

  • Exchange Server 2010: move mailboxes from recoveded and mounted edb to user’s mailbox

    - by user36090
    One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed.

Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

  • How to re-arrange Excel database from 1 long row, into 3 short rows of unequal lengths and automatically repeat the process?

    - by user326884
    This question is an extension/continuation of my previous question at How to re-arrange Excel database from 1 long row, into 3 short rows and automatically repeat the process? which was answered by Jason Lewis of which I'm grateful. But being a dummy in "Indirect' Excel function, I need assistance again : For example :- In Sheet A, Row 1 has the following data in each cell (all together 72 cells occupied): A1 B1 C1 D1 E1 F1 G1 H1 I1 J1 K1 L1 M1 N1 O1 P1 Q1 R1 S1 T1 U1 V1 W1 X1 Y1 Z1 AA1 AB1 AC1 AD1 AE1 AF1 AG1 AH1 AI1 AJ1 AK1 AL1 AM1 AN1 AO1 AP1 AQ1 AR1 AS1 AT1 AU1 AV1 AW1 AX1 AY1 AZ1 BA1 BB1 BC1 BD1 BE1 BF1 BG1 BH1 BI1 BJ1 BK1 BL1 BM1 BN1 BO1 BP1 BQ1 BR1 BS1 BT1 To be re-arranged into Sheet B in the following format: Row 1 : A1 B1 C1 D1 E1 F1 G1 H1 I1 J1 K1 L1 M1 N1 O1 P1 Q1 R1 S1 T1 U1 V1 W1 X1 Y1 Z1 AA1 AB1 AC1 AD1 AE1 AF1 AG1 AH1 AI1 Row 2 : AJ1 AK1 AL1 AM1 AN1 AO1 AP1 AQ1 AR1 AS1 AT1 AU1 AV1 AW1 AX1 AY1 AZ1 BA1 BB1 BC1 BD1 BE1 BF1 BG1 BH1 BI1 BJ1 BK1 Row 3 : BL1 BM1 BN1 BO1 BP1 BQ1 BR1 BS1 BT1 The Sheet A (database sheet) has a lot of rows (example 3,000 rows, each rows has 72 cells occupied with data), hence the Sheet B (reformatted database) is estimated to have 9,000 rows (i.e. 3 x 3,000) of unequal lengths. Thanking you in anticipation of your speedy response.

  • Question marks showing in ls of directory. IO errors too.

    - by jaymoo
    Has anyone seen this before? I've got a raid 5 mounted on my server and for whatever reason it started showing this: jason@box2:/mnt/raid1/cra$ ls -alh ls: cannot access e6eacc985fea729b2d5bc74078632738: Input/output error ls: cannot access 257ad35ee0b12a714530c30dccf9210f: Input/output error total 0 drwxr-xr-x 5 root root 123 2009-08-19 16:33 . drwxr-xr-x 3 root root 16 2009-08-14 17:15 .. ?????????? ? ? ? ? ? 257ad35ee0b12a714530c30dccf9210f drwxr-xr-x 3 root root 57 2009-08-19 16:58 9c89a78e93ae6738e01136db9153361b ?????????? ? ? ? ? ? e6eacc985fea729b2d5bc74078632738 The md5 strings are actual directory names and not part of the error. The question marks are odd, and any directory with a question mark throws an io error when you attempt to use/delete/etc it. I was unable to umount the drive due to "busy". Rebooting the server "fixed" it but it was throwing some raid errors on shutdown. I have configured two raid 5 arrays and both started doing this on random files. Both are using the following config: mkfs.xfs -l size=128m -d agcount=32 mount -t xfs -o noatime,logbufs=8 Nothing too fancy, but part of an optimized config for this box. We're not partitioning the drives and that was suggested as a possible issue. Could this be the culprit?
