  • Web Writing Services - When It's Time to Pass the Ball

    When it comes to making our online marketing campaigns a success, most of us would be better off hiring a variety of web writing services to help. After all, while we've all seen (and envied) the one-man-act extraordinaire, there isn't too many of us who haven't been victim to the frazzled, pressure-cooker feeling of having sole responsibility for our companies' successes either. Besides, who in their right mind would put that kind of pressure on themselves when outsourcing to a web writing service can be just as profitable?

  • Installed without the usual menus. Now I can't log in

    - by Martha
    I tried to install from CD. The computer wouldn't boot from the CD, so I clicked on the 'boot helper', and rebooted the machine. And the first thing I see is do I want to open Windows or Ubuntu (without it asking me whether I wanted to install it alongside Windows or replace it), and when I click on Ubuntu, after a very long time, I finally get a login screen. But I don't have a login, because I never set one up. Help!

  • When creating a library for a simple program, what must I do to protect others from its lack of thread safety?

    - by DeveloperDon
    When creating a library for a simple program, is it more cost effective to make it thread safe or is there a way to detect the program's use in a multithreaded program and ASSERT() or otherwise determine (preferably at compile or link time) that it may create problems. Related help for this question would be automated tool support for finding potential problems with thread safety, programming language features that enforce it,

  • MSVC++ Resource (.rc) files tutorial? [closed]

    - by Serge
    I'm looking for a good tutorial for making resource files (*.rc) in MSVC++. I've been googling, and nothing has been useful in the slightest. What I'm looking for is a guide for how to actually write, manually, a *.rc file. Anything I have found so far, especially on MSDN, has only been about how to use the Visual Studio menu options to let it create resources for you. I'm not interested in that. Anyone able to help?

  • Network config / gear question

    - by mcgee1234
    I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

  • Control Parameters and DropDownList Text

    - by Bunch
    This is something that I rarely need to do, grab a DropDownList’s selected item’s text for use in a datasource’s ControlParameter. To allow for this use SelectedItem.Text instead of the more common SelectedValue for the PropertyName. <asp:ControlParameter ControlID="ddlStuff" Name="stuffName" Type="String" PropertyName="SelectedItem.Text" /> The reason for using this is for text comparison. On rare occasions you may need to check the text against a list where the SelectedValue just does not help. Technorati Tags: ASP.Net

    good night my project is about that Write a program that uses a loop to calculate the first 15 values of the Fibonacci number sequence and store them in an array, call it FibArr, of size 15 DWORDS. Fibonacci number sequence is described by the following formula: Fib(1) = 1, Fib(2) = 1, Fib(n) = Fib(n -1) + Fib(n - 2). Place each value in the EAX register and display it with a call DumpRegs statement.So I dont have an idea about this topic please help me thanks

  • Optionally Running SPSecurity.RunWithElevatedPrivileges with Delgates

    - by Damon Armstrong
    I was writing some SharePoint code today where I needed to give people the option of running some code with elevated permission.  When you run code in an elevated fashion it normally looks like this: SPSecurity.RunWithElevatedPrivileges(()=> {     //Code to run }); It wasn’t a lot of code so I was initially inclined to do something horrible like this: public void SomeMethod(bool runElevated) {     if(runElevated)     {         SPSecurity.RunWithElevatedPrivileges(()=>         {             //Code to run         });     }     else     {         //Copy of code to run     } } Easy enough, but I did not want to draw the ire of my coworkers for employing the CTRL+C CTRL+V design pattern.  Extracting the code into a whole new method would have been overkill because it was a pretty brief piece of code.  But then I thought, hey, wait, I’m basically just running a delegate, so why not define the delegate once and run it either in an elevated context or stand alone, which resulted in this version which I think is much cleaner because the code is only defined once and it didn’t require a bunch of extra lines of code to define a method: public void SomeMethod(bool runElevated) {     var code = new SPSecurity.CodeToRunElevated(()=>     {         //Code to run     });     if(runElevated)     {         SPSecurity.RunWithElevatedPermissions(code);         }     else     {         Code();     } }
