• list and explanations of ways to boost this router's signal strength? [closed]

  - by barlop

  Possible Duplicates: Improve Wireless Signal How to get wireless coverage over my whole house? What's the best way to increase the range of my 802.11g router? The back of my house doesn't have WiFi Signal I'm interested in ways that are both specific to certain routers, and generic. When I say generic, I don't necessarily mean a one way that works for many.. but it can also be a generic answer, so mentioning solutions for different situations. So not just the one router I mention. Explanations are important, as well as all the ways. One i'm particularly interested in boosting the strength of is this wireless router/modem Netgear VMDG280 maybe anywhere in a big house with three floors, maybe from the garden.

• If an entity is composed, is it still a god object?

  - by Telastyn

  I am working on a system to configure hardware. Unfortunately, there is tons of variety in the hardware, which means there's a wide variety of capabilities and configurations depending on what specific hardware the software connects to. To deal with this, we're using a Component Based Entity design where the "hardware" class itself is a very thin container for components that are composed at runtime based on what capabilities/configuration are available. This works great, and the design itself has worked well elsewhere (particularly in games). The problem is that all this software does is configure the hardware. As such, almost all of the code is a component of the hardware instance. While the consumer only ever works against the strongly typed interfaces for the components, it could be argued that the class that represents an instance of the hardware is a God Object. If you want to do anything to/with the hardware, you query an interface and work with it. So, even if the components of an object are modular and decoupled well, is their container a God Object and the downsides associated with the anti-pattern?

• Route SOAP request through external server

  - by sanbornm

  I need to integrate with a SOAP Web Service that requires that the requests come from a whitelisted IP address. As I often do development from all over the place it is quite annoying to ask for a new whitelisted IP each time. I have a remote server that is whitelisted. How can I route my SOAP request (I can change the endpoint in the WSDL) to my remote machine and have that forwarded to the Web Service? My remote server is used for other things so it needs to only forward a specific port, not all traffic. Oh, and the Web Service expects SSL.

• Restore open applications, documents, and window state

  - by rfeague

  When working on a project, I generally have a couple of Explorer windows open to relevant folders and a couple of applications (e.g. Eclipse and a form development tool) open to specific project-related documents. There's a lot of value in that context, and I'd like to find a way to save a set of open apps under a project name, then restore that state at a later date. Thus far all of the utilities I've found are virtual desktop products that don't save/restore state. I'm specifically looking for something that will run the applications I had running, open the documents I had open, and position the windows as they were. I'm amazed that such a seemingly simple concept as "Save my workspace state" doesn't seem to be available. I'm on Windows 7. Any suggestions?

• where is this SPF problem occuring

  - by Saif Khan

  Hi, Inbound mail to a specific user is been forwarded to his external mailbox at another domain. Add mails are routed correctly with the exception of one domain. When mail are sent to users of my domain, including that user, the mails are delivered to everyone except him...as the mail admin I am getting the message The following recipient(s) cannot be reached: usermailbox on 1/10/2011 1:27 PM There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. email.speedimpex.com #5.5.0 smtp;587 [email protected] sender domain does not match SPF records I am sure this has nothing to do with my mail server, however, can someone confirm?

• Is it possible to power off a PCIe video card/slot? (eg. hot-plug)

  - by CR.

  I'm looking at building a system that supports VT-d so I can pass through a high powered loud video card to a Xen/KVM/whatever VM (host will be Linux based). However, when I'm not using the VM I want to turn the video card off so its fan does not run. The card will not be used when the VM isn't running. Anyone know if this is possible? The PCI-Express hot-plug specification allows cutting power to specific slots but I have never heard of anyone doing it with a video card and my searches for information have turned up nothing.

• Meeting reminders disappearing after accepting

  - by stayinwett

  I have a particular user whose Outlook is acting up. Whenever he accepts a meeting invitation from a specific person, the reminders get turned off in the calendar. Every other person who got the meeting invitation still gets the reminders. This is the only thread that I found somewhat relevant: http://www.eggheadcafe.com/software/aspnet/32118199/lost-functionality-when-accepting-meeting-requests.aspx This is weird though because he doesn't have any rules that should cause the meeting invitations to be stored in a weird folder or anything, they are left alone. I tried loading his profile and accepting the invitation on my end, and it went through fine (it was marked down in the calendar with a 15 minute reminder). When I looked at previous meetings he accepted from that person, there is indeed no reminder set. Any suggestions? Windows XPSP3, Outlook 2007, Exchange 2k3

• What are the pros & cons of these MySQL engines for OLTP -- XtraDB, PBXT, or TokuDB?

  - by Continuation

  I'm working on a social website with an approximate read/write split of 90/10. Trying to decide on a MySQL engine. The ones I'm interested in are: XtraDB PBXT TokuDB What are the pros and cons of them for my use case? A few specific questions: PBXT uses log-based structure that avoids double-writes. It sounds very elegant, but the benchmark I've seen doesn't show any/much advantages over XtraDB. Do you have any experience with PBXT/XtraDB you can share? TokuDB sounds VERY interesting. But all the benchmarks I've seen are about single-threaded bulk inserts - inserting 100M rows for example. that's not very relevant for OLTP. What about its performance with large number of concurrent threads writing and reading at the same time? Anyone has tried that?

• Remote desktop connection dos not respond anymore (no more task bar)

  - by Bronzato

  I have a remote desktop connection (from my home) to the company's server. On this I opened a Remote Desktop Connection Manager and inside this connect to a specific server. I was busy copying a file but this task never ends. So I kill the process and now I have a blue screen and no more taskbar. Very frustrating. When I try CTRL+ALT+END (=CTRL+ALT+DEL) this is executed on the main server and not the server which gives me the blue screen. I don't know if I'm clear. I know I should have keep Task Manager open and type Run... explorer.exe but I closed it. Any help is really appreciated!

• How to apply a folder template to more than one selected folder in Vista?

  - by Albic

  I would like to apply a folder template to a number of folders. I selected the folders, opened the properties, selected the folder template (e. g. Music Details) and clicked OK. When I checked the folders I noticed that the template was only applied to the folder I performed the right click to open the properties on. The other folders remained untouched. I can't apply the template to the parent folder and use the "Also apply this template to all subfolders" option because the template should only be applied to specific folders and not all. Going over each folder in not an option because it's a large amount of folders. Is it possible to apply a folder template to more than one selected folder at a time?

  I want to delete a network connection. When I type net use I get this: Microsoft Windows XP [version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.

The syntax for deleting a network map is : net use /delete X: if I want to delete a specific connection net use /delete * * if I want to delete all connections. How can I delete the \192.168.2.43\data connection which, as you can see, is not link to any logical letter?

• Batch print, reprint and scan

  - by Nikita K. Tsarov

  I am using ubuntu 13.10 with Epson wireless scanner/printer/fax WF 2540(It has an automatic document feeder- ADF). What I am trying to achieve is to be able to print with confidence over already populated A4 pages(hand drawn or otherwise). The idea is to get a batch of A4 pages grouped in a particular order and have them batch printed on specific parts of each page ,viewed on screen and edit/processed page by page. My idea was to batch scan the documents in order and display each scanned page to use that to judge/fit on-screen the coordinates for the output of each pages image... The easiest way to explain this is to look at these slide : https://drive.google.com/file/d/0B0Kuhf6iBidTNUl3U1NtT0pGbnc/edit?usp=sharing I would like to have this automated as much as possible using this printer but I am open to other suggestions. Are there any other better printers that can automatically scan and print at the document that is being scanned...with an accurate positioning in relation to elements already printed on the page?? Are there any other forums I should be asking and looking for answer/suggestions on my case/dilema??

• Windows Server 2003 seems to pick the 'outgoing' IP address at random from all the ones configured in IIS, how can I make it just use one?

  - by ioSamurai

  We have multiple sites in IIS with different IP addresses. This is cool, want different IPs to all go to this server and use the proper site. However I discovered an issue that when the server makes an outgoing connection, I cannot predict which IP it will use. I had to have one client add ALL the IPs to their firewall so that a certain service could communicate with their server. Well now the time has come to add another IP/site to IIS but I had told them they would not need to add any more IPs. So the question is, how can I make Windows Server 2003 use only ONE specific IP for outgoing calls instead of it being unpredictable? If this is not a good enough description, when I was RDPed into the server and I opened IE and went to 'what is my IP' it was sometimes different which is how I discovered why the one client's firewall was suddenly refusing the connections. How can I just make outgoing calls originate from a static IP yet still allow multiple IPs pointing to different sites in IIS?

• Filemaker show total from related table

  - by Mr_Chimp

  I have a bit of experience with Access and SQL but I'm new to Filemaker. I have a layout which shows a list of projects. One of the fields I want it to show is "total amount of paid invoices up to the end of the last financial year". The invoices are stored on another table so I will need to pick from this table all records where "project id" = "project id" (this is set up as a relationship between the tables) and also "invoice is paid" = yes AND "date invoice paid" < start of last financial year. My question is how do I go about getting and showing that data? I can get a total easily enough, it's filtering out these specific rows that I'm having trouble with. I'm guessing there's an easy solution...

• How to know which protocol is used in data transfer and inspect that data?

  - by user37880

  I've a .net application for windows. This application transfers a lot of data to and from a particular server on a fix port no 8888. I tried 'Tcpview' but couldn't figure out anything useful. I only figured that it uses 'tcp' connection. Is there a way to know which protocol is used for data transfer (I think port no 8888 is not specific port so not helpful)? How exactly my machine makes connection to this server? Is it telnet/http etc or what? How can I inspect the actual data which is being transferred? If data is encrypted, is it possible to know encryption method on client side (without reverse engineering)? Thanks.

• How to learn to program [on hold]

  - by user94914

  I went to a community college and got a degree in computer science, but I found out I only learn very little about programming. As a result I landed byself a office assistant work (for a year now), I want to study on my own and apply for some internship / very entry level development job. I am wondering how should a person learn to program now? I feel that I might not doing it correctly, I understand everyone has a different approach, but I am really clueless on what to do, as it seems I am 5-10 years away. 1) Read the old college programming textbook cover to cover, learn every single concepts, do all the practice problems and master them (1-2 times until error free). Currently reading this java book 2) Work on any project, keep on googling and reading tutorials (including the books on that specific language). I have been doing 1, but the progress is really slow, about 2-5 pages / hour, over a 1000+ page book, I felt really discouraged. I have a few of them to go through (data struction, analyis algorthim, computer theory, operating system.) I wonder is this the right method to do? I know it is going to take time, but I am hoping to get some advice from current programmers.

• Get Directory Size through SFTP

  - by Nongo

  A client has a managed websever; on this server is an e-commerce script and part of the script dumps a backup every week. The backup is stored on the web server (not in the HTTP route). The ISP takes a copy, and my clients wants to take a copy too. What I am trying to do is before downloading the file I want to be able to calculate the backup directory size - but the only access I have is through SFTP. Is it possible to easily get the directory size and then use this in a PowerShell Script. NOTE: I have written an automatic download script in Powershell, and I want to extend this. Forgive me if this sounds vague I can provide further info if you have any specific questions.

• Web hosting deciding to pay for hosting or host your own?

  - by pllee

  Is there a guide out there on how to choose when to pay for web hosting vs. hosting your own? Assuming that root access is a must I would like to compare things like cost, scalability and personal stress. Here is what I could come up with. Paying for web hosting: Benefits: Much cheaper for a small scale. I assume anything under $50 a month would be cheaper than paying for the bandwidth of hosting. No stress in dealing with power outages, server restarts or internet going down. For the most part less busy work involved with setting up. Negatives: Cost goes way up when higher specs are needed (for example monthly cost triples with ability to use 8gb of ram that you can buy for $90 ). This means you have to target a particular ram usage and monitor so your instance stays within the threshold. root access for the most part is a premium. You may get tied into a vendor specific deployment process. Hosting on own : Positives: 100% control of specs and software. When you get past paying for the bandwidth you get much more bang for your buck by building your own machine. Negatives: Doesn't make financial sense if bandwidth costs are more than web hosting costs. Having to deal with power outages, server restarts or internet going down. I think the best of both worlds would be if there was a place that dealt with bandwidth, power outages and server restarts but you provided your own server. Kind of like a 24 hour day care for a server. Does anything like that exist?

• Alternative to cPanel (For Email, ect)

  - by Dboy1612

  I'm currently setting up a VPS for the first time. Standard that I've ever worked with before on shared hosting was cPanel, but as the majority of my work I plan on doing from now on will be using NodeJS and Python/Flask, I'd like to avoid needing to install Apache/MySQL/PHP. What would be my best bet to help manage a mail server other than cPanel? Or even other specific server settings that may come in handy later? Plan on using Ubuntu if that counts for anything.

• TCP handshake ok, then the client isn't receiving any packets from the server

  - by infgeoax

  Topology: Client ----- Intermediate Device ----- Server Client: win7 Intermediate Device: unknown Server: CentOS 5.8 The problem occurs when the client and server are trying to establish a SSL connection. It happens to one specific port, 2000. I haven't been able to replicate the problem with other port numbers. I captured packets on both client and server. After the TCP handshake, from the client's perspective, it's not receiving ACKs for its previously sent packets so it kept re-sending them. On the server side, however, it did receive those packets and sent ACK packets. The weird thing is, after the server sent those ACKs, it received a [RST, ACK] packet, from the intermediate device, for every packet it sent. What could be the cause?

• How can I check that I'm not frying the chipset on my 945 gclf?

  - by Journeyman Geek

  I'm running an old 945 gclf as a home server. Its an odd little system which has a passively cooled single core atom 230 processor, and a small heatsink/fan combo over the chipset. lm-sensors/sensors detects one temperature sensor which I guess is the processor. coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (crit = +100.0°C) The fan on it is making rather horrible noises and I am considering unplugging it or using a speed reducer. There's also a risk it may fail anyway. Is there any way I can monitor the temperatures of the chipset or be warned of any issues with it? Is there anything specific I can watch out for that would indicate trouble?

• USB Permission - Write protection

  - by dekhadmai

  I have an external harddisk and my friends asked for it. The point is I don't trust in his anti-virus software. Is there anyway to allow some folders (I prepare hdd space for him) to write-able and all others is read-only ? or is there a software that can do like this ? And it would be great if I can have full access on my computer ONLY (may be with some specific software on my PC) and without having to modify anything. I don't ask for hdd-encryption since I only want to limit the area of write-able folder (and allow my friend to read through all my data), later I can scan for virus myself only in that area ... scanning entire hdd with 500gb/friend is not fun at all ! Sorry if this doesn't seems like the programming questions. Any help would be appreciate, Thank you.

• Upgraded from ubuntu 12.04 to 12.10 issues

  - by ubuntu novice user

  I recently upgraded 12.04 to 12.10 ubuntu and then all hell broke loose. Being more specific, I have a Compaq machine and its hard disk is partitioned into 3 parts, so when I installed Ubuntu 10.04, I installed it in windows, since then have upgraded with each new ubuntu release via the update manager without any problems. I have installed the 64 bit versions. 12.10 downloaded via update manager, and initial downloading of packages was without problems, however, as it tried to install the packages, error messages appeared. The first was one about missing lib files, but I clicked to continue, since I am a relative novice on ubuntu. It continued, and during the restart process, when it was powering down, the computer hanged on the shutting down bit without rebooting for more than half an hour, so I manually shut down the machine and restarted it. Then a new error message appeared stating could not find disk, and I hit the manual fix option, and it now boots to an empty ubuntu desktop with my wallpaper but no launcher and the graphics appears as if this was put on a 640 x 480 resolution, and the screen no longer fits onto my 19" LCD. I had to use Ctrl-Alt-T to log out and then restart from there. How can I resolve this issue. Please help!

• Public domain usage of imagery from films? [on hold]

  - by AdamJones

  I'm thinking of starting a small film site, which would begin as a simple blog. Imagery from films I discuss on the site would be vital to the look and feel of this site. Instantly though this makes me wonder about copyright/public domain rights for such imagery. I just wondered if anyone had general or specific advise about using imagery from this industry or another similar situation? On the one hand I know the film industry aggressively tries to protect its IP (fair enough), but on the other hand, surely film companies do release some imagery of their films in stills format into the public domain to simply help their distribution and advertising efforts? I have tried looking on stock photo galleries for images of film stills but only found moviestillsdb.com) which seemed very limited in its results. I've researched a bit about fair usage (http://fairuse.stanford.edu/overview/fair-use/) as well, which I know applies to the USA specifically. This seems to suggest that a still of a film is within these bounds. Still, any constructive advise others may have as a result of experience dealing with imagery, from film or another domain would be greatly appreciated, assuming it isn't "get a lawyer".
