  - by user3215

  I've apache2,tomcat6 ubuntu servers running on port 80 with mod_jk setup hosting jsp pages. The developers are complaining that the pages are being rendered very slow when tried with IE browser and saying, at every refresh the images are reloading again and again which is not happening with other browsers. I'm given a hint CDNwhich I've no knowledge but I found in the google that cdn makes pages available on many server which improves the speed of the page being rendered. Anybody could tell me how could I make my pages available in cdn servers?

• Are there any concerns with using a static read-only unit of work so that it behaves like a cache?

  - by Rowan Freeman

  Related question: How do I cache data that rarely changes? I'm making an ASP.NET MVC4 application. On every request the security details about the user will need to be checked with the area/controller/action that they are accessing to see if they are allowed to view it. The security information is stored in the database. For example: User Permission UserPermission Action ActionPermission A "Permission" is a token that is applied to an MVC action to indicate that the token is required in order to access the action. Once a user is given the permission (via the UserPermission table) then they have the token and can therefore access the action. I've been looking in to how to cache this data (since it rarely changes) so that I'm only querying in-memory data and not hitting a database (which is a considerable performance hit at the moment). I've tried storing things in lists, using a caching provider but I either run in to problems or performance doesn't improve. One problem that I constantly run in to is that I'm using lazy loading and dynamic proxies with EntityFramework. This means that even if I ToList() everything and store them somewhere static, the relationships are never populated. For example, User.Permissions is an ICollection but it's always null. I don't want to Include() everything because I'm trying to keep things simple and generic (and easy to modify). One thing I know is that an EntityFramework DbContext is a unit of work that acts with 1st-level caching. That is, for the duration of the unit of work, everything that is accessed is cached in memory. I want to create a read-only DbContext that will exist indefinitely and will only be used to read about permission data. Upon testing this it worked perfectly; my page load times went from 200ms+ to 20ms. I can easily force the data to refresh at certain intervals or simply leave it to refresh when the application pool is recycled. Basically it will behave like a cache. Note that the rest of the application will interact with other contexts that exist per request as normal. Is there any disadvantage to this approach? Could I be doing something different?

• Lenovo W520 back usb port not working

  - by jaudette

  The usb port in the back of my laptop (on the right side when viewed from using perspective) is not working. Does anybody know if we can get this port working, and what the port number is. Here is my lsusb, if it can help. % lsusb Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0024 Intel Corp.

The two usb ports on the left work just fine. EDIT: I just updated my bios from 1.32 to 1.39, no change in behaviour. The port does not even power up my devices. EDIT 2: Booted up windows, and the port is working. I went into the device manager and looked at the USB settings. I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux. In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1 EDIT 3: Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled. Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.

• Random links seo and spam

  - by DoesNotCompute

  I built a mini-forum with social features for a client, to promote user registration, i planned to add a box on the forum pages to display pictures with profile links of random registered users. I managed to make this random selection static for a day, i mean the list will be renewed each day and not change on every page refresh. Could this random list of link could be harmful to seo by being considered as some kind of spam?

• Does AdSense serve higher CPC ads to a website that has higher number of visits?

  - by Silver Moon

  For the same niche and same set of keyword, does Google AdSense serve higher CPC ads to a website that has higher number of visits? I have observed that for similar niches 1 website (with 3K daily uniques) makes around $100 a month, and another website (with 10k daily uniques) makes around $700-800 a month It seems that the earning curve is not linearly dependent on visit count and somewhat increases at a rate faster than the growth of visits, this leads me to think if the Google AdSense algorithm serves higher CPC ads once a website starts getting a large number of visits.

• TPC-H Benchmarks on SQL Server 2014 with Columnstore

  - by jchang

  Three TPC-H benchmark results were published in April of this year at SQL Server 2014 launch, where the new updateable columnstore feature was used. SQL Server 2012 had non-updateable columnstore that required the base table to exist in rowstore form. This was not used in the one published TPC-H benchmark result on SQL Server 2012, which includes two refresh stored procedures, one inserting rows, the second deleting rows. It is possible that the TPC-H rules do not allow a view to union two tables?...(read more)

• How to fix laggy mouse and keyboard on Ubuntu 10.04 LTS 64bit?

  - by Goi

  I've just installed Ubuntu 10.04 LTS 64bi on my i5-2400 system, and I'm experiencing very laggy keyboard and mouse input. I have to type really slowly or I some keys will not get registered. Also, the mouse cursor moves around very slowly at a very low frame rate. I've checked my keyboard and mouse settings and they seem to be fine. System monitor doesn't show any processes taking up significant CPU utilization. What else could be wrong?

• Speed up your Silverlight Debugging for large projects

  - by Aligned

  I'm working on a 5+ year old ASP.NET project that has 74+ projects and we've been adding new Silverlight applications to run in the ASP.NET page islands. My machine at work isn't the most powerful, so I find myself waiting a lot for the whole thing to build. I'm using Visual Studio 2010, so that takes up a lot of resources as well. This causes me to get distracted and I start looking at the news... I need to combat that more :-). I can't get a new machine, that's up to someone else, so I've found a few tricks to help. 1. Only build the Silverlight project you're working with. This will build all referenced projects (you can see these by right clicking and clicking Project Dependencies) and package a new XAP (you can see all the actions in your output build window). Then refresh your page with the Silverlight app and it's up-to-date. 2. I was working with a co-worker (thanks Jordan) who was using the the Debug -> attach to processes window. In the Attach to: row there is a "Select..." button. In the dialog, click "Debug these code types:" and select Silverlight. Hit ok. Then all you need to do is find your process (you might need to click the refresh button). I'm usually debugging in IE, so I select the first one and push "i" on the keyboard. That brings me to the IE windows open. Find the one with type of Silverlight, x86. It is usually directly above one with type of x86 that has the page title for "title". Click attach and watch your output window spit out messages about loading debug symbols and your breakpoints enabled (if this doesn't happen you chose the wrong process, hit stop and try again). Now you can debug the client code as normal, server code requires a full F5 or attaching to the correct process. To improve this even further, bind the menu item to a key stroke. I chose ctrl + x, x. (Tools -> Options -> Keyboard, search for Debug.AttachToProcess, set the shortcut keys globaly and assign). Most of the time I build the project, then hit ctrl + x, x then i, then enter and I'm debugging. The process I want is usually the first IE in the list.

  Hello! When I use ffmpeg to convert an audiofile with the option -acodec libfaac -ab 192k and use ffmpeg -i on that file afterwards to get the audio file information, it tells me bitrate: 152 kb/s Why ist this? Do I miss something here? If I want to convert a file with a bitrate of 192kb it should give me 192 kbit after the conversion, shouldn't it? Or: How do I get the 192 kbit rate then?
