• Is there an use case for non-blocking receive when I have threads?

  - by Gabriel Šcerbák

  I know non-blocking receive is not used as much in message passing, but still some intuition tells me, it is needed. Take for example GUI event driven applications, you need some way to wait for a message in a non-blocking way, so your program can execute some computations. One of the ways to solve this is to have a special thread with message queue. Is there some use case, where you would really need non-blocking receive even if you have threads?

• How to prove worst-case number of inversions in a heap is O(nlogn)?

  - by Jacques

  I am busy preparing for exams, just doing some old exam papers. The question below is the only one I can't seem to do (I don't really know where to start). Any help would be appreciated greatly. Use the O(nlogn) comparison sort bound, the theta(n) bound for bottom-up heap construction, and the order complexity if insertion sort to show that the worst-case number of inversions in a heap is O(nlogn).

• Option 82 and dhcpd. "No free leases" for second computer

  - by SaveTheRbtz

  There is DHCP server in network (isc-dhcpd-server-3.0 on FreeBSD 7.2) than gives one IP per switch port to every user via Option 82 The problem appears when user disconnects one of his computers and connects another(i.e notebook with different MAC address) then DHCPD puts to log "...network net1: no free leases", because there is record in leases file that this IP is already owned by another MAC. That second computer will have his IP only after default-lease-time (that is IIRC minimum 10min, and after 3min he usually calling support) or after deletion of dhcpd.leases file and restart of dhcpd. Is there a way to turn leases off at all, because we have strict binding between switch-port-ip?

• How to fix? => Your system administrator does not allow the user of saved credentials to log on to the remote computer

  - by Pure.Krome

  At our office, any of our Windows 7 Clients get this error message when we try and RDP to a remote W2K8 Server outside of the office :- Your system administrator does not allow the user of saved credentials to log on to the remote computer XXX because its identity is not fully verified. Please enter new credentials A quick google search leads to some posts they all suggest I edit group policy, etc. I'm under the impression, that the common fix for this, is to follow those instructions -per Windows7 machine-. Ack :( Is there anyway I can do something via our office Active Directory .. which auto updates all Windows 7 clients in the office LAN?

• How do you recommend installing Linux on a computer that has no external drive or ability to boot fr

  - by 7777

  I have an old Toshiba Portege 3505 "ultralight" laptop, meaning it doesn't have any kind of disk drive on it at all, that I'd like to completely reformat and install Linux on. However, it won't boot from any drive (and I don't have any on hand), so I'll have to install it from a USB drive (which I doubt it boots from either). (I'm not sure how to change the settings in my BIOS to get my computer to boot from a USB stick. Any ideas for this?) How do you recommend I do this? I want to note that I don't want to run Linux off a LiveUSB, I want to actually install it on the machine. I was thinking about Damn Small Linux, it's tiny and all I need. Any advice or suggestions for something else though? Finally, I'm a total newbie to this, I've never installed Linux on anything before so I might be a little slow on some stuff! Thanks!

• Is it possible to have a computer run two OS's in memory at the same time?

  - by Hebon

  I'm sick of needing to reboot my computer every time I wish to use another OS, or run a virtual machine that skimps on power. With the onset of large amounts of memory for computers nowadays I began to think that there must be some way to run two OS's in memory with a way to switch between the two. In my mind, it doesn't seem too difficult; a compatibility layer boots up after bios, which in turn boots to OS1. While in OS1, software is run that triggers a save to ram boots back to the compatability layer, and then boots to OS2. This way, the OS's can be used side by side and boot times are cut drastically short since both OSs are already in ram. Both OS's have their own designated and protected memory so there is no problem there... I mean, it seems fine, but no one has done it, so there must be some reason as to why. I would love some insight into this please.

• How to make a streaming server to stream media from computer to mobile phone in wifi?

  - by zkz

  Usually we have many HD movies in our computer, but we want to see them by our mobile phone. This requirement produces some questions: 1?the HD videos are too big to transfer to phone timely and it it hard to play on phone smoothly, so we have to transform the videos smaller and fit the screen of phone. 2?the coded format of the videos are varied, but limited types are supported by mobile phone, so we should transform the coded format to those supported by mobile phone. I've leaned the streaming media fit this problem, what I want is: 1?are there any good opensource projects fit this(ffmpeg?live555? darwin?)? 2?are they quick enough to transform coded format and transfer to mobile phone to play with no delay? Thank u very much!

• What VNC (or similar) software for Windows 7 Home allows me to control my parents’ computer remotely as an administrator user?

  - by Paul D. Waite

  Here’s what I dream of: I install Windows 7 Home on my parents’ PC. They have a regular user account that they use, meaning they can’t install anything. I have an administrator account, meaning I can install things for them. I install some sort of VNC software on their machine that lets me access their computer remotely under the administrator account, so that I can install software for them (or do other administrator tasks, e.g. updates) without actually going to their house. Is there any VNC or VNC-like software that supports the above? (I guess I might be better off buying them Windows 7 Professional, and using Remote Desktop. At some point I’ll give up and get them an iPad, but for now, remote Windows admin is the dream.)

• Is it possible to use Logmein to connect to a sleeping (Mac) computer on a wireless network?

  - by jaydles

  I'm using logmein to access my Mac. So I have the local logmein app running on my MacBook Pro, which is on my home wireless network. I access it either from the website (www.logmein.com) or the Logmein Ignition Apps on the iphone or ipad. My problem is that I have to set my MacBook Pro to not sleep at all when plugged in to make this a practical solution, because logmein cant seem to wake it up. I did change the settings in System Preferences to allow "Wake from Lan", but it seems like this won't work with a a Wifi connection. Am I missing anything? Assuming I'm not, is it bad for my computer to basically leave it running and not asleep most of the time?

• What is the best MTA setup for a home/laptop computer (*not* server)?

  - by thomasrutter

  Hello, What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that is not always online? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they have a static IP have a domain name are always connected to the same network My requirements are, I guess: Ability to redirect mail for local users to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

• How to send a popup message to unknow computer connected to my WLAN?

  - by Leandro

  Is there any way to send a popup message from a Linux systen to a "random" laptop/tablet/mobile linked to my Wireless network ? For example, if I let my WLAN open and I see a not recognized computer connected to it, is there anyway to send to that device a message ? On the other hand, if I am connected to someone else open network and they may or may not be aware that their network is open, can I send them a message warning that I am accessing their network? Probably for a completely "random" device the answer should be no. But if we restrict to laptops with Win7 or Linux SO is there any service running by default on such systems that allows one to send such popup messages ? PS: I have no practical motivation for this question. This is only a curiosity.
