  • Raising events vs direct method calls differences

    - by dotnetdev
    Hi Raising an event, will call its event handler. eg http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx What is the difference between using the events mechanism and direct calls to other methods (eg if a condition is met in method A(), call B() )? And what is the difference between consuming and raising events? Thanks

  • Python: if key in dict vs. try/except

    - by LeeMobile
    I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

  • ConcurrenctBag(Of MyType) Vs List(Of MyType)

    - by Ben
    What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

  • vs 2010 colors are darker than i set

    - by Genrih
    I have "Selected Text" color set to a default value in vs 2010 RGB 51,153,253. But really in text editor it is RGB 173,214,255 that is slightly darker. The same things are with some other colors, e.g. Resharper Dead Code. What can it be a problem and how should I solve it?

  • Using VS Code Snippets with Resharper

    - by devoured elysium
    I am trying to use Code Contract's Code Snippets but since I turned Resharper back on it doesn't recognize them. On the other hand, it is recognizing some snippets I've implemented myself in the past. Any ideia of what might be the problem? I'm specifically trying to use cr and ce, which I think, don't collide with any other snippets (at least from what I see in the intellisense). I'm using R# 5 with VS 2010 Thanks

  • Two imageViews vs one imageView and a canvas

    - by user3009842
    I have a bitmap and I want to scale it up to fill an ImageView and overlay the unscaled version of the bitmap on top. Which would be cheaper (in terms of memory and processor usage)? Using two ImageViews, one for each version of the bitmap Using a canvas and drawing on the singular bitmap, using one ImageView I saw this question about ImageView vs Canvas, but it doesn't address memory/processor concerns. My intuition says two ImageViews may use more RAM, while using a canvas would use more processing power while the drawing occurs.

  • Core i7-620M vs Core i5-540M

    - by Shalan
    Hi, I'm recommending a laptop to a colleague, and the specific laptop he has chosen has the above CPU chips as options. Both chips have 2-cores/4-threads. The i7-620M is a 2.66 GHz (4MB Cache) while the i5-540M is a 2.53 GHz (3MB Cache)....both Arrandale architecture. He is a .NET programmer working with SQL Server and Oracle, and occasionally uses Adobe Fireworks for web-related design elements. He also loves playing around in Adobe Premiere Pro, and does a lot of media/video work. Would you notice any significant performance difference between the 2? The laptop manufacturer claims that the battery life on both is the same irrespective of the chip used (although I find that hard to believe), but there is a major cost difference between them, with the Core i7-620M being the more expensive. According to http://ark.intel.com, the one thing that seems different (besides the obvious speeds/frequencies/etc) is a feature called "Embedded" - what is this exactly? You can see the quick comparison here - http://ark.intel.com/Compare.aspx?ids=43544,43560 I would sincerely appreciate any advice me on this. THANKS!

  • cisco 2911 router vs 2811 router

    - by NickToyota
    Just wondering if anyone has experience with the cisco 2911 or 2900 series routers. I understand it is newer and similar to the 2811 but more robust. The price difference is not that much more. I am trying to determine if I should go with the 29xx or 28xx series for a small-medium sized company. ISP bandwidth load balancing and fail over is required. T1 and ADSL lines already in place.

  • Windows Server 2012 Branchcache vs. DFS-R

    - by TheCleaner
    Warning, subjective question ahead! But hopefully a good one that won't get closed. SCENARIO: I have a branch office that currently has no on-premise server. They access everything including a DC across a 12Mbps WAN link (MPLS). The link isn't saturated, averaging around 20% utilization. The circuit is very stable and has a high SLA and excellent uptime. However, large file transfers (mainly reads, not writes) from the file server across the WAN can be slow. We don't currently utilize DFS. RESEARCH DONE: I'm aware of WAN acceleration, using either dedicated hardware (Riverbed) or a dedicated software VM (Silver Peak) for example. But the pricing is outside of our current budget and the need isn't quite there yet from our perspective (since the issue is mainly in a "pull" scenario not necessarily push/pull). I'm mainly looking at deploying a Windows server at this branch office and either utilizing DFS-R or BranchCache. Looking at a table comparison and assuming we are looking at a "hosted branchcache server" and not simply distributed: It would appear there are benefits to both, even if both are "hosted" on a server. QUESTIONS I ACTUALLY HAVE: In what scenarios do each of these techs shine and where do you choose one over the other? Looking at a hosted Branchcache server, can you set "pre-fetching" of certain folders/files on the central file server so that they are immediately accessible locally at the branch? Do you have to do this on a schedule (if it is possible)? Looking at DFS-R my concern (and apparently solved with 3rd party apps) is file locking and making sure the file gets updated properly during a write operation (ie, making sure if both copies are accessed and both are written to, which file takes precedence and what happens to the changes?). Ideal it would seem would be to lock any alternate replicas of the data, but is it really that big of an issue? Does Branchcache lock the central file for editing? Does branchcache only transmit the deltas back to the central file of what has changed? Would either technology be ill advised if the branch office server was going to be utilized as a domain controller as well?

  • Confluence vs Sharepoint

    - by FerranB
    We use Confluence mainly for documentation and want to make an step forward moving all the files (pdfs, etc) to Confluence but we want to determine if it's the best option. As far as I know Confluence is a wiki and Sharepoint is not. How compare confluence and Sharepoint as file containers? Which benefits have Sharepoint over Confluence and vice-versa? Pros and Cons?

  • multiple monitor, ATI EyeFinity vs NVidia Mosaic on HDMI

    - by user1531897
    i have been googling much for answer but only someone with real experience can help here. my aim is to have 5 monitors connected to one computer in 2x2 full screen on all 4 monitors (video wall) with same resolution, 4xfullHD for example, plus one -5th monitor as controling. Ati have example picture of this configuration here. I have no gaming nor 3d needs here. Simple desktop applications plus video streams. So because graphic cards for this are expensive, i need to find out before buying pros and cons of 2 possible solutions (1) Ati Eyefinity capable card(s) ...and (2) Nvidia Quadro/NVS card(s) with mosaic and/or nvidia surround technology. For example i can find that current good cards for this can be: Ati's 7870 eyefinity6 card, link here pros: one card can handle all 5 displays, cons: active DP adapters needed (sometimes with aditional usb-powering complication) Nvidia Qudro NVS 450, link here Both cards have DisplayPorts as outputs (my targets are HDMI displays), but as far i saw information is that Eyefinity needs "active DP-DVI/hdmi adapters" for outputs and they are little expensive...? Does nvidia have this limitation (active adapters) ??? And final question, is Ati Eyefinity still better for this purpose than Nvidia-mosaic by someone's real experience there.

  • Master/Slave DNS setup vs. rsync'ed DNS servers

    - by Jakobud
    We currently have primary and secondary DNS servers on our corporate network. They are setup in a master/slave type setup, where the slave gets its DNS information from the master. I'm trying to figure out what the real advantage is for the master/slave setup instead of just setting up an automated rsync between the two to keep the DNS settings matched. Can anyone shed some light on this? Or is it just a preferential thing? If that is the case, it seems like the rsync setup would be much easier to setup, maintain and understand.

  • Zimbra vs. Kerio Connect

    - by rahum
    We've been a Kerio partner for years and have deployed much Kerio Connect. Now we're looking at beginning hosting groupware for our clients and are wrestling over the right backend. Kerio Connect is fantastic, but we have a couple gripes: Kerio is often weeks behind on releases to keep up with major Microsoft and Apple updates that break functionality or at least impede new Apple/Microsoft features in their desktop clients We've been worried that Kerio has a historical habit of corrupting Apple's Open Directory; we know this happened years ago, and have suspected it happening earlier this year There's always some one or two features that are buggy in Kerio, in every release. These usually aren't dealbreakers, just annoyances. Kerio does not have any kind of HA feature set How does Zimbra compare? What are your gripes? Thanks! noam

  • Onboard RAID vs Software RAID

    - by mvid
    My motherboard, an Asus M4a79t Deluxe, advertises RAID 0/1/5 capabilities. My limited understanding is that onboard RAID is better than software RAID. Is this necessarily true? Is an onboard RAID controller closer in performance to a software controller or a dedicated hardware controller?

  • Forefront TMG vs pfSense

    - by Macropus
    We currently run pfSense with no problems, however we are looking at TMG as it is included in our partner subscription to MS and allows Windows 7 DirectConnect features to our domain for off-site users. I have had a google, but there don't seem to be any comparisons of TMG to pfSense. Anyone have experience/knowledge of this? Our infrastructure is Windows Server 2008 R2 behind pfSense at the moment.
