• How to transfer large files from desktop to server ( .NET)

  - by rahulchandran

  I am writing a .NET 2.0 based desktop client that will send large files ( well largish under 2GB) to a server. Need to develop the server as well. Server can be on any technology It should be secure so an underlying SSL stream is needed What are my options. Any obvious caveats etc I should be aware of To my mind the simplest solution is to open a tcp\ip connection over SSL to the server and send n packets each of size M bytes and then have the server append the chunks to the file and finally send an EOF packet as well IS this horrible. Will the perf suck on the server with all these disk writes What are any other clever options. I am limited to .NET 2.0 on the client if I did move to a WCF client will it buy be something magical and cool for this scenario Thanks

• Installing Chrome OS on HP Pavilion

  - by Lenny K

  Trying to install Chrome OS on HP Pavillion tx1000. I changed the BIOS to boot from USB before hard drive, and created a bootable USB drive (SanDisk Cruzer 4GB). No matter how many ways I try to make the USB drive, the laptop hangs on the startup screen, and trying to open the Boot Order Options freezes on "Fixed disk 0: ...". On the other hand, without the USB plugged in, the computer continues, and displays "Initialized Mouse", and then onto the Boot Order Options. If you let it boot normally from the beginning, it starts up fine into Windows Vista. I am using Hexxeh's Chrome OS build. Here are the different methods I've tried for making the Bootable USB Drive: Hexxeh's Image Creator (for Mac) Making the USB device bootable (using these directions). I wrote the image using Win32DiskImager. Writing the image using Win32DiskImager (without making it bootable).

• Algorithm for calculating indefinite integrals

  - by mbac32768

  Suppose I have an integral that's bounded on one (or both) ends by (-)infinity. AFAICT, I can't analytically solve this problem, it takes brute force (e.g. using a Left Riemann Sum). I'm having trouble generalizing the algorithm so that it sets the proper subdivisions; I'll either do far too much work to calculate something trivial, or not do nearly enough and have huge aliasing errors. Answering in any language is cool, but maybe someone with better google-fu can end this quickly. :) Is what I'm looking for as impossible as trying to measure the British coastline?

• Reusability, testability, code complexity reduction and showing-off-ability programming importance

  - by Andrew Florko

  There are lots of programming and architecture patterns. Patterns allow to make code cleaner, reusable, more testable & at last (but not at least) to feel the follower a real cool developer. How do you rank these considerations for you? What does affect you most when you decide to apply pattern? I wonder how many times code reusability (especially for MVP, MVC patterns) was important? For example DAL library often shared between projects (it's reusable) but how often controllers/views (abstracted via interfaces) are reused?

• Share files - Ubuntu 12.4 and Windows 7 - one network - password not accepted

  - by gotqn

  I have three machines - two with windows 7 and one with Ubuntu 12.4 version. There are in the same network connected by modem. The two machines shares file with no problem, but they can not see the machine with Ubuntu. On the other hand, I am able to see the share files of the windows machines from the Ubuntu's Network. When I select a folder, it wants the network password - I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong. I have read some topics about files sharing between Linux and windows in which it is said that I should use samba, but is there a more easy way to do this, using the build it options?

• WLC 4400. Get IP

  - by Edward Connelly

  I have three SSID. one is a guest network and I'm having problems with lease times. Its set for web authentication so it passes IPs out even if someone doesn't try and authenticate. Is there a way to get that IP back and not hand another to that mac for a period of time? Poor planning and we didn't allocate enough address space, and we are sandwitched. We could go with another address, but we would have to reconfig lots. since its guest its vlan'd with no access to anthing but the firewalls. would have to change ACLs and routes and interfaces. if it isn't possible we will just have to go that route, just thought there might be an easier solution. session timeout is enabled with 1 hr lease time is set to 4 hrs. no helper DHCP and internal DHCP is set with the space split across three WLCs (60 waps split across those as well).

• Is the iPad in Europe totally unblocked?

  - by Mike

  One fast question: if I buy an iPad 3G in Europe will it work on other places without jailbreak? I ask this because I heard that, in Europe, iPads are not blocked to any telecom but I am not sure about that. On the other hand I am afraid do buy because I know that their cousins, iphones, are blocked to a specific telecom. Another question is regarding activation. As far as I remembered, my iPhone required me to do an activation step on iTunes and I remember it was also activated (or whatever) on the store (I remembered the salesman connected it to a computer and did some stuff before giving me the device). Is the iPad in europe totally free of operator? totally unblocked? thanks.

• just another apache to nginx rewrite question

  - by Brandon

  I have the following Apache rewrite directives: RewriteCond %{REQUEST_URI} ^/proxy(/|$) [NC] RewriteCond %{QUERY_STRING} (^|&)uri=(.*?)(&|$) [NC] RewriteRule .* /api/vs1.0/%2 [NC,L] And I'm trying out nginx, so trying to move the rewrites over. I came up with... rewrite ^/proxy(/|$) /api/vs1.0/$2 last; rewrite (^|&)uri=(.*?)(&|$) /api/vs1.0/$2 last; Which is probably grossly incorrect. I'm just a mere web developer, so I was wondering if anyone could lend a hand here. I would be much obliged. I see that I am ignoring the query string specification, but I'm thinking that it shouldn't matter. I only have a vague idea of what the original rewrite is accomplishing, so I haven't much hope here in coming up with something decent, despite reading the relevant documentation for both servers.

• sIFR3 smoothing and IE

  - by Misiur

  Hi, i've started to use sIFR3. I don't know how to turn on smoothing of font. Do i need to change it in my font.swf file? In FF3 it work perfect, everything is okay, but when i turn on my IE8, nothing changes. Even live example doesn't work (http://work.likeaninja.co.uk/sifr/demo/). What's going on? My Flash Player is "WIN 10,1,51,95" (http://kb2.adobe.com/cps/155/tn_15507.html). I thinks it's beta, but it shouldn't change anything. Help!

• Mysterious "media" volume mounted on desktop Mac OS X

  - by Allen

  I have a mysterious volume mounted on my desktop that I can't seem to forcibly unmount. I've tried using umount and also diskutil, but it seems to automatically remount itself. I've copied my hdd with Time Machine, and copied it onto a new computer, and it also has the drive mounted on it. It's not pointing to anything and I can't open it, nor can I forcibily remove it by hand with rm -Rf. Any ideas? I noticed this problem after I upgraded to Mountain Lion from Lion. It causes problems because when I try to select a file using the built in Finder dialog box, it freezes for a few minutes because it tries to cache or read into the "media" mounted volume.

• What is the character used to indent the Make file rule recipe?

  - by goldenmean

  Hi, I am using gnu make and in a Makefile I have, I see below rule. I want to add a similar rule with a recipe, but when I add a rule and its receipe on the next line by giving a tab or space for the recipe, I get make error. dummy : @echo $(OBJS) When i turned on the vim command :set list , i see: dummy :$ ^I@echo $(OBJS)$ What exactly are the characters before the recipe line(second line) which indent it from the start of line? How do I enter them using keyboard (without having to copy paste the exisitng rule and then modifying it? Where would I find information for various spaces/indents to be used in creating a Makefile from beginning, by hand(Not a automake/or other tool created makefile)? thanks, -AD.

• Full coordinates across streets with google maps

  - by nbv4

  If you go here: http://econym.org.uk/gmap/snap.htm there are some examples of the kind of stuff I'm trying to do. I want the user to enter a route on a google maps widget, and then have the map drawl the route along roads. Then the user click on a "submit" button, and their route is sent back to the server where it will be stored in a database. Instead of sending back just the red vertices, I want to send back all the information that makes up the purple lines. Is this possible?

• Picasa 3 - All 88 'people' folders are empty - can I restore the files?

  - by rogerbid

  My wife uses Picasa 3 on her laptop, and has a problem. She has no idea how it happened but somehow the left hand panel in the Picasa 3 window shows "People (88)" but listed below it are the 88 names each with "(0)" alongside. No thumbnails show up for any of the 'people'. I have looked through all the menus and can see nothing that seems relevant and a search on this website has been fruitless too. Can anyone please tell me how I can correct this situation? FYI I backed up the laptop to a portable hard drive a few days ago (using Windows Backup and Restore) and wonder if this can be used to restore the database.

• Is Exchange protected from/allow back dated emails?

  - by David

  Does Exchange Server adequately protect against backdating items in a mailbox folder? I want to determine from an auditing perspective what level of risk exists/what trust can be put into Exchange database records. Is there a (mis)feature that allows end point users to modify the sent/recieved date fields on their own messages? Is there a reasonable way short of hand editing the files for an Exchange Server admin to make such a change? And most importantly: Is there any kind of "sequence number" that we could use to audit Exchange records for evidence of date manipulation (ex. msg100 = Dec 15, msg101 = Dec 10, msg102 = Dec 16)

• Would you hire a foreigner ? [closed]

  - by user229999

  Hi! I'd like to dedicate this question (hope it's not a subjective) especially to people who own their companies. Would you (and why) hire a foreigner, which experience is documented in CV and portfolio, which can communicate in english (with grammar mistakes, but still)? I am writing in the name of all these guys looking for great opportunities abroad, living in countries which do not give you any opportunities at all. Is it real, to be hired like a programmer (PHP, Ruby, Python, C#) in country like UK, USA, Nederland, Sweeden or even Germany, if you're a foreigner? Please response in two categories: a) foreigner with engineer degree, zend certificate, few open source projects b) foreigner without any degree, with nice portfolio, and few big projects created Also, does First Certificate in English aka FCE matter for you ?

• Taking two actions in monit

  - by Oddthinking

  My monit script works to detect an outage with a process and inform me when the rule is: IF DOES NOT EXIST THEN ALERT My monit script works to detect an outage and automatically fix it when the rule is: IF DOES NOT EXIST THEN START But, what I want it to do is inform me AND fix it. Two rules in a row seems to make it ignore all but the last: IF DOES NOT EXIST THEN ALERT IF DOES NOT EXIST THEN START # No alert given. I could use a custom script that does both, and IF DOES NOT EXIST THEN EXEC "my_handwritten_script" but I was trying to move away from a mess of hand-written scripts towards a clean Monit configuration. Can I configure Monit to take two actions?

• What does the term 'overinstallation' mean?

  - by Kent Pawar

  I came across this term here: "11882875 -- Essbase Server does not start after an overinstallation." I know that a clean install is a software installation in which any previous version is removed. Googling 'overinstallation' turned up nothing, and I don't like to just assume it simply means 're-install'. UPDATE: So my understanding now is - the term "re-install" can be a bit ambiguous as it could either signify an installation after an uninstallation or otherwise. On the other hand the term "over-installation" specifically talks about installing something over an existing installation, that involved no uninstallations.

• Maintaining a set of (virtual) windows XP machines

  - by Frank Meulenaar

  I have a small set (currently 3, going to 6, not going to be more than 10) of (virtual, vmware workstation) windows XP machine's. They are similar but not exactly the same. I'm currently rolling out windows updates etc by hand: start machine 1, update, close, etc; I'd like to review the updates first before the clients can install them. Incidentally there are also other updates to be performed: changes some files on all machines, install new Java versions, etc. What's a good way of doing this automatic? I tried to search for this but things like Active Directory seem overkill to me.

• Windows 7 - Static DHCP server address with dynamic IP Address

  - by mkstreet

  Is this possible? On my LAN, I would like to setup the network properties such that the DHCP server's address is static. However, I want that server to hand out the IP Addresses and DNS addresses dynamically. The reason is that some devices on the LAN will try to behave like a DHCP server. For example, we use software to push images to computers on the LAN (our computer software configurations are centrally managed). When that imaging distribution software happens to be running, the machines being imaged will get confused as to which device is the DHCP -- the real one or the machine that is sending them the image. So, to remove the confusion, I would like to setup my Windows 7 images such that the DHCP server address is statically assigned. And then that server would assign the IP Addresses and the DNS addresses dynamically.

• XamlXmlReader.Read() does not yield matching XamlNodeType.StartObject and XamlNodeType.EndObject on

  - by Yuval

  Hi, I am trying to parse a valid xaml file using the XamlXmlReader. It looks like it is 'skipping' some elements when when Read() is called. for example on the following xaml snippet: <UserControl.Resources> <Converters:AnyDbTypeToDisplayNameConverter x:Key="anyDbTypeToDisplayNameConverter" /> </UserControl.Resources> when reading I first get a XamlNodeType.StartObject on UserControl.Resources - makes sense then another XamlNodeType.StartObject on Converters - also cool. but then i do not get a XamlNodeType.EndObject on the Converters and immediately jump to the next line and does not report a XamlNodeType.StartObject. Any Idea if this is working as design ? looks like a bug to me

• Using WCF to expose underlying process

  - by Steven

  I have a server application that spins up and monitors about 8 separate processes that gather data from different systems. The server app then runs some calculations over the aggregated data and stores it in a db. Simple stuff. I now have a requirement to modify the process so that it no longer saves data to the db but rather exposes it directly to clients via WCF. That's cool, I've used WCF a fair bit but I'm struggling a little with it for some reason. Basically my plan is to HOST the WCF service in my application and have calls redirect into the internals of my existing application but I can figure out how to do that without getting the WCF class to encapsulate the existing app. I want the service to inside my current app, not become it. Any suggestions?

• Why are developers proud to say our application is XXX lines of code? [closed]

  - by mbcrump

  I admit, I used to do it. I was proud to tell a fellow developer my application is 10K+ lines of code. I thought it was a "Look at me, I'm smart" statement. Time passed and I realized that a experienced developer would be constantly refactoring all of his code. Not only for the sake of remembering what it was doing, but because he realizes he is smarter today than he was yesterday. No longer was it cool to have multiple nested if statements or completely ignoring generics/lambdas. So, whats your take on this? Do you do it and why?
