• What is the most reliable session storage in PHP: Memcache, database or files?

  - by user1179459

  What is the best and most safest way to handle PHP sessions. Is the best way to store sessions in: Database (more reliable, but high bottleneck, slow speed, not good for high database usage websites)? Memcache (super fast, but distributed more security problems, chances of loosing data when the server restarted and chances of loosing data when the cache is full)? Files (default option, I guess slow since it reads and writes from file I/O, less security, etc). Which method is the best? What are the problems and good things of each of those approaches?

• Creating a Reporting Services Histogram Chart for Statistical Distribution Analysis

  Typically transactional data is quite detailed and analyzing an entire dataset on a graph is not feasible. Generally such data is analyzed using some form of aggregation or frequency distribution. One of the specialized charts generally used in Reporting Services for statistical distribution is Histogram Charts. In this tip we look at how Histogram Charts can be used for statistical distribution analysis and how to create and configure this type of chart in SSRS.

• Caching issue with Centos forwarding DNS server

  - by Paddington

  I installed a Forwarding DNS server on Centos 5.10 and it is resolving addresses e.g google.com. When I stopped named (service named stop) and tried to dig (dig @localhost A google.com) there was a failure to resolve the address. I checked and see the caching daemon nscd is running. Does this mean the server is not caching at all? How can I get it to cache? named.conf options { // Those options should be used carefully because they disable port // randomization // query-source port 53; // query-source-v6 port 53; // Put files that named is allowed to write in the data/ directory: listen-on port 53 {127.0.0.1; 10.0.0.4;}; directory "/var/named"; // the default dump-file "/var/named/chroot/var/named/data/cache_dump.db"; statistics-file "/var/named/chroot/var/named/data/named_stats.txt"; memstatistics-file "/var/named/chroot/var/named/data/named_mem_stats.txt"; // allow-query {localhost; 192.168.0.0/24; 10.0.0.0/8;}; recursion yes; //allow-query { localhost; 10.0.0.0/8;}; allow-query { localhost; any; }; allow-query-cache { localhost; any; }; forward only; forwarders {8.8.8.8; 8.8.4.4;}; dnssec-enable yes; // dnssec-lookaside auto; /* Path to ISC DLV key */ // bindkeys-file "/etc/named.iscdlv.key"; // managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; **

• User input and Automated input seperation

  - by tpaksu

  I have a mysql db and I have an automation script which modifies the data inside once a day. And, these columns may have changed by an user manually. What is the best approach to make the system only update the automated data, not the manually edited ones? I mean yes, flagging the cell which is manually edited is one way to do it, but I want to know if there's another way to accomplish this? Just curiosity.

• Azure Florida Association: Modern Architecture for Elastic Azure Applications

  - by Herve Roggero

  Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

• Free web "caching" services for a web service

  - by Jason Banico

  I have a web service on Google App engine whose data is updated on a daily basis. To minimize bandwidth utilization from mobile clients connecting to it, I'd like to instead have an intermediary site where the clients will be getting their data from, and minimizing hits to my service to once or twice a day only. Is there such a service I can use? I'd like to explore this "pull" option first, before considering "push" options such as publishing to a blog site or a free website host that doesn't have bandwidth caps.

• SQL Transactional Replication snapshot not applying

  - by dmch2

  Hi, I'm using SQL Transactional Replication with pull subscriptions to replicate databases (hosting their own distribution database) from several servers across a VPN to a central server. I've got the first 2 databases working fine but the 3rd one is causing me problems. My subscription server is SQL 2008, the source systems are all SQL 2005. The source databases are a few 100Mb in size and contain audit data so are simply growing slowly by adding new records at approx 1kb a second. As far as the replication monitor, Agent logs and event logs show everything is working fine - except that no data appears in my subscription database. The distribution agent doesn't seem to want to read the snapshot (and hence the initial state and schema) from the publisher. New transactions aren't applied although they do seem to be arriving OK as the replication monitor shows things like '5 transactions with 10 commands were delivered'. I would expect (as in previous times) to see statements about data being BCPed in the replication monitor. The snapshot is on the publisher on a shared folder. The subscriber can view the snapshot OK (\\repldata) and the alt snapshot folder is pointing at it. But the distribution agent doesn't seem to be making an attempt to do read it. I tried changing the snapshot path to something that's incorrect and didn't even get an error saying that it couldn't access it. After lots of googling etc I found that sp_MSget_repl_commands is called by the subscriber on the distribution database on the publisher. Running a profiler I can see that it's only called for one agent Id. After a reinit it's called for sequence number 0x0 as expected so I thought that would mean it's would look for the snapshot. However, looking on the publisher I see that there's data for two agents - the snapshot agent and the log reader agent (which is being queries). So I guess I need to tell the distribution agent to get the data for both. But how? and more importantly - why? It worked fine on the other two servers I've replicated. I'm not an SQL novice but this is pretty much my first go at replication so don't be afraid to accuse me of missing something obvious/stupid! I can get log files (eg from the distribution agent) if you want but they don't seem to have any errors in them - it just starts up and starts applying log reader agent changes. Cheers Dave

• A Tale of Identifiers

  Identifiers aren't locators, and they aren't pointers or links either. They are a logical concept in a relational database, and, unlike the more traditional methods of accessing data, don't derive from the way that data gets stored. Identifiers uniquely identify members of the set, and it should be possible to validate and verify them. Celko somehow involves watches and taxi cabs to illustrate the point.

• HTG Explains: How Hackers Take Over Web Sites with SQL Injection / DDoS

  - by Jason Faulkner

  Even if you’ve only loosely followed the events of the hacker groups Anonymous and LulzSec, you’ve probably heard about web sites and services being hacked, like the infamous Sony hacks. Have you ever wondered how they do it? There are a number of tools and techniques that these groups use, and while we’re not trying to give you a manual to do this yourself, it’s useful to understand what’s going on. Two of the attacks you consistently hear about them using are “(Distributed) Denial of Service” (DDoS) and “SQL Injections” (SQLI). Here’s how they work.

• Get selected object from TreeView

  - by GoGoDo

  I've been working on a minor (first time) app with quickly and hit a hurdle - how do I get the selected row (the data) from a TreeView? The data to the TreeView is passed from a list of files in a directory, and I need to know which rows were selected (and thus which files were). What is the best way to do that? Here's the current code: self.treeview = self.builder.get_object("treeview") select = self.treeview.get_selection() select.connect("changed", self.on_tree_selection_changed) def on_tree_selection_changed(selection): model, treeiter = self.treeview.selection-get() if treeiter != None: print "You selected", model[treeiter][0]

• Access Control Service v2: Registering Web Identities in your Applications [code]

  - by Your DisplayName here!

  You can download the full solution here. The relevant parts in the sample are: Configuration I use the standard WIF configuration with passive redirect. This kicks automatically in, whenever authorization fails in the application (e.g. when the user tries to get to an area the requires authentication or needs registration). Checking and transforming incoming claims In the claims authentication manager we have to deal with two situations. Users that are authenticated but not registered, and registered (and authenticated) users. Registered users will have claims that come from the application domain, the claims of unregistered users come directly from ACS and get passed through. In both case a claim for the unique user identifier will be generated. The high level logic is as follows: public override IClaimsPrincipal Authenticate( string resourceName, IClaimsPrincipal incomingPrincipal) {     // do nothing if anonymous request     if (!incomingPrincipal.Identity.IsAuthenticated)     {         return base.Authenticate(resourceName, incomingPrincipal);     } string uniqueId = GetUniqueId(incomingPrincipal);     // check if user is registered     RegisterModel data;     if (Repository.TryGetRegisteredUser(uniqueId, out data))     {         return CreateRegisteredUserPrincipal(uniqueId, data);     }     // authenticated by ACS, but not registered     // create unique id claim     incomingPrincipal.Identities[0].Claims.Add( new Claim(Constants.ClaimTypes.Id, uniqueId));     return incomingPrincipal; } User Registration The registration page is handled by a controller with the [Authorize] attribute. That means you need to authenticate before you can register (crazy eh? ;). The controller then fetches some claims from the identity provider (if available) to pre-fill form fields. After successful registration, the user is stored in the local data store and a new session token gets issued. This effectively replaces the ACS claims with application defined claims without requiring the user to re-signin. Authorization All pages that should be only reachable by registered users check for a special application defined claim that only registered users have. You can nicely wrap that in a custom attribute in MVC: [RegisteredUsersOnly] public ActionResult Registered() {     return View(); } HTH

• Contiguous Time Periods

  It is always better, and more efficient, to maintain referential integrity by using constraints rather than triggers. Sometimes it is not at all obvious how to do this, and the history table, and other temporal data tables, presented problems for checking data that were difficult to solve with constraints. Suddenly, Alex Kuznetsov came up with a good solution, and so now history tables can benefit from more effective integrity checking. Joe explains...
