• Isopropyl okay to use on MacBook screen?

  - by Archagon

  I've always used a mixture of isopropyl alcohol and distilled water to clean my computer screens (50% water and 50% * 70% isopropyl). From what I understand, these are exactly the same ingredients used in most commercial screen cleaners, perhaps even more diluted. I recently used this solution to wipe off my 2010 MacBook Pro screen, and there don't seem to be any problems, but this support page explicitly says not to use isopropyl. Now I'm worried that I might have inadvertently damaged something. I'm also concerned because I once managed to dissolve the surface rubber lining of one of my mice with the isopropyl solution, and the MacBook Pro display has a thin rubber bezel keeping the glass in place. Why would Apple single out isopropyl on their support page? Should I be concerned?

• Intel RAID0 on Windows 8 not Displaying Correct Media Type

  - by kobaltz

  I have my primary C Drive which consists of 2 Intel 120GB SSD Drives in a RAID0. I have a clean install of Windows 8 Pro, latest MEI software, latest RST software, latest Intel Toolbox. Prior to this I had installed Windows 8 Pro as an upgrade. When I went into the Optimize Drives while in the Upgrade installation, it showed the Media Types as Solid State Drives. However, now since I am in a brand new install, it is showing the Media Type as Hard Disk Drive. I am worried about this because of the trim not working properly. Before when in the upgrade, it showed SSD as the media type and the Optimize option would perform a manual trim. Unfortunately, my search credentials on Google are so common to many other things (ie Raid0, SSD, Windows 8, Media Type) that all I am finding are useless topics. Before, (found on random site) it showed the Media Type as below

• How do I import a Flash Catalyst design into Dreamweaver?

  - by garrett

  So I made a banner in Flash Catalyst and published it to swf/air file. Now I can't find a way to get it into Dreamweaver. When I hit "Import SWF" and go to browse for it, it doesn't show up. When I publish it to swf, the file is a Jscript script file. I've been looking for tutorials, but I haven't found one for my issue. Currently I am downloading Flash Pro and hoping I can import the Catalyst design into that, then import the Flash Pro design of it into Dreamweaver. I am not very advanced in Catalyst or Dreamweaver, but I do know my way around a bit, and this is causing me one hell of a headache.

• Booting CDs/USB devices after installing Windows 8

  - by shoyip

  I recently installed Windows 8 on one of my four primary partitions. I had two partitions for Windows 7 (boot and os), one for the Windows System Recovery Environment and the last for Ubuntu. I was often using Ubuntu, but after the installation of Windows 8 Pro I couldn't boot in it because it needed the reinstallation of GRUB2. So I thought to do it by Terminal in a live cd; but when I tried to boot the Live CD, it booted me Windows 8 Pro. This is a problem of UEFI, Secure Boot or my BIOS? It didn't happen never before now. And if it's a problem of Secure Boot, how to disable it? Thanks in advance, Sho.

• How can I have a Makefile automatically rebuild source files that include a modified header file? (I

  - by Nicholas Flynt

  I have the following makefile that I use to build a program (a kernel, actually) that I'm working on. Its from scratch and I'm learning about the process, so its not perfect, but I think its powerful enough at this point for my level of experience writing makefiles. AS = nasm CC = gcc LD = ld TARGET = core BUILD = build SOURCES = source INCLUDE = include ASM = assembly VPATH = $(SOURCES) CFLAGS = -Wall -O -fstrength-reduce -fomit-frame-pointer -finline-functions \ -nostdinc -fno-builtin -I $(INCLUDE) ASFLAGS = -f elf #CFILES = core.c consoleio.c system.c CFILES = $(foreach dir,$(SOURCES),$(notdir $(wildcard $(dir)/*.c))) SFILES = assembly/start.asm SOBJS = $(SFILES:.asm=.o) COBJS = $(CFILES:.c=.o) OBJS = $(SOBJS) $(COBJS) build : $(TARGET).img $(TARGET).img : $(TARGET).elf c:/python26/python.exe concat.py stage1 stage2 pad.bin core.elf floppy.img $(TARGET).elf : $(OBJS) $(LD) -T link.ld -o $@ $^ $(SOBJS) : $(SFILES) $(AS) $(ASFLAGS) $< -o $@ %.o: %.c @echo Compiling $<... $(CC) $(CFLAGS) -c -o $@ $< #Clean Script - Should clear out all .o files everywhere and all that. clean: -del *.img -del *.o -del assembly\*.o -del core.elf My main issue with this makefile is that when I modify a header file that one or more C files include, the C files aren't rebuilt. I can fix this quite easily by having all of my header files be dependencies for all of my C files, but that would effectively cause a complete rebuild of the project any time I changed/added a header file, which would not be very graceful. What I want is for only the C files that include the header file I change to be rebuilt, and for the entire project to be linked again. I can do the linking by causing all header files to be dependencies of the target, but I cannot figure out how to make the C files be invalidated when their included header files are newer. I've heard that GCC has some commands to make this possible (so the makefile can somehow figure out which files need to be rebuilt) but I can't for the life of me find an actual implementation example to look at. Can someone post a solution that will enable this behavior in a makefile? EDIT: I should clarify, I'm familiar with the concept of putting the individual targets in and having each target.o require the header files. That requires me to be editing the makefile every time I include a header file somewhere, which is a bit of a pain. I'm looking for a solution that can derive the header file dependencies on its own, which I'm fairly certain I've seen in other projects.

• How to have 2 windows machines on the same network with the same IP address

  - by Stu

  I have a custom made ADC device that is spitting out data by addressed UDP packets. I have that device plugged into a 4 port switch. I have one windows embedded standard 7 machine which is the normal recipient of that data. To be able to receive the data (Using LabVIEW) the windows network adapter IPv4 settings must have a static IP address that corresponds to the UDP packet destination. I would like to add a second windows machine (This one is just regular Win 7 Pro) to simultaneously catch the data, however with all devices connected to the switch, the Win 7 Pro machine recognizes an IP address conflict and will not take the setting for the required static IP address. (The network adaptor settings show that the correct value has been entered but ipconfig shows that it is not actually set.) Neither windows machine needs to transmit network data, they only need to be able to receive the UDP data from the ADC device. Is there any way to disable this IP address conflict detection 'feature' of windows networking?

  Hi! I'm using MEF for a plugin-system to my application. The flow goes like this: Run all Pre-plugins Run all Core-plugins Run all Post-plugins For example, if a plugin in the Core execution fails, i don't want to run certain post plugins. What would be the best way to achieve this? Hope my question is clear, otherwise please tell me and i'll try to elaborate.

• When is it time to buy a new hard drive, and what considerations go into buying a new hard drive?

  - by user1125620

  I've had my current hard drive for about 4-5 years now, and I've never had a problem with it before, but now it's making whirring noises. It's done this before and, last time, the noise did go away the next day, but I have accumulated quite a bit of information that I wouldn't want to lose on the drive. HD Tune Pro and Berlac Advisor both said the drive was healthy, and I wouldn't want to get a new one unless it was absolutely necessary or was going to show drastic performance improvements. My only knock against the drive would be that Visual Studio takes longer to load than I'd like it to. HD Tune Pro says the average read speed is 54.3MB/s. I'm not sure if that's good or bad, but it seems about average compared to similar drives on http://www.hdtune.com/testresults.html. Model #: WDC WD5000AAJS-22YFA0 So, should hard drives be replaced after a certain amount of time? Has mine reached that point? Would a new hard drive be any faster?

• Can I make a computer connecting via VPN visible to computers within the network it is connecting to

  - by SCdF

  OK, here's the deal: I have a computer (specifically, a MacBook Pro) that is connected to a standard network that is then connected to the big nasty internet. Let's call it foo. It runs a web server on 8084, and so if you were on its local network you could get to this with http://foo:8084/, or http://192.168.1.2:8084/, or whatever. From foo I can VPN into my companies intranet and see a computer on the local company network called bar (another MacBook Pro, incidentally). Is there any way to set this up so that while foo is on the VPN bar can access http://foo:8084/ (or http://x.x.x.x:8084/, or whatever)? (From my limited understanding of how VPNs work I have a sneaking suspicion the answer is no, but it doesn't hurt to ask...)

• Asus EEE PC 1005HA (XP Home) refuses to connect to Virgin Mobile MiFi

  - by Dennis Wurster

  My client has an Asus EEE PC model 1005HA, and we're attempting to connect it to the WiFi network created by a VirginMobile MiFi unit. They also have a MacBook Pro with Snow Leopard that has absolutely no issue connecting to the MiFi. The specific symptom is that the netbook fails to lease an IP address from the MiFi unit. I supply the 12-digit numerical password (WPA) to the netbook, it throws a 'waiting for network' dialog with an indeterminate progress indicator, and then times out. Update: We've determined that this behavior has stopped when the EEE PC and the MiFi unit were taken out of the client's home, and to a different home that didn't have an existing wifi network. Similarly, when taken to a third location that didn't have wifi, the EEE PC and MiFi got along swimmingly. My current theory is that the existing wifi networks and the wifi leg of the MiFi unit are on the same channel and competing with one another. Perhaps the MacBook Pro has the capability to overcome this interference, while the EEE PC doesn't.

• java.lang.NullPointerException exception in my controller file (using Spring Hibernate Maven)

• Automatically Connecting to Hidden SSID WiFi Network

  - by Zack

  My MacBook Pro will not automatically connect to a Wireless network with a hidden SSID. It makes me select the "Join Other Network..." in the Airport menu (in the system tray), where I need to input the name of the network, then security type, password and wait for it to connect. This is becoming increasingly annoying to have to do every time I come back to my desk. I'm running Mac OS X 10.5 and there doesn't seem to be an option to connect to a specific network, but rather "Preferred Networks." The only network I have set as Preferred that's in range is my home network, and it still doesn't automatically connect. Making the network publicly visible isn't under my control, so I'm stuck with what's currently in place. Reader's Digest version: How do I make my MacBook Pro automatically connect to a WiFi Network with a hidden SSID without having to "configure" it every time I want to connect?

• Is it reasonable to use OpenGL for desktop applications?

  - by JamesK89

  I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

• Joining H264 *without* re-encoding

  - by jdmuys

  I have two halves of a single show in two .MP4 files, encoded in H264. I would like to join them without re-encoding. Is this possible? I managed to create a joined video as a Quicktime file (.mov) using Quicktime Pro, but then Quicktime Pro will not convert it back to .MP4 without re-encoding. This may be because looking inside the .mov file, the two H264 videos are in there still separated as individual "objects". I am also struggling with MPEG StreamClip without reaching a real solution. But I may have missed something. Note that I do not have the same issue with MPEG2 files. I can export them to a .MPEG container or a .TS file for example, and then I can join them without re-encoding using MPEG Streamclip. Any suggestion welcome, preferably using Mac software.

• After installing updates, Windows 7 reboots when it gets to "Preparing to Configure"

  - by Travis

  After letting Windows 7 Pro install updates at shutdown I now cannot get it to boot back up. I have tried selecting safemode, and "last known working configuration" and I get the same results. It gets to the screen and says "Preparing to configure Windows" and then reboots. If it is giving me a BSOD it is happening so fast I can not see it. This is a generic PC that has been running fine for the last year. It had 22 updates to do at shutdown. Windows 7 Pro Service Pack 1 64 bit in an Active Directory Domain.

• Why does the Mac OS X (10.6) Finder stop being able to connect to Windows computers?

  - by Drarok

  We have one Mac (a MacBook Pro Unibody) amongst our Windows machines which connects to the "server" (actually a Dell running Windows XP Pro) to access documents. This works just fine most of the time, but sometimes after waking from sleep, it cannot connect to any Windows computer on the network. There are no errors (nor even any messages) in the Console application when attempting to connect either by the Finder's network browsing, nor when using the "Connect To Server" menu. I have tried "Relaunch" on Finder, toggled File Sharing, disabled and re-enabled the Airport, but nothing makes the Mac able to connect again until I reboot it! Other computers can connect to the machines, so it is definitely the Mac at fault. Are there any workarounds that anyone has found? Is there perhaps a way to re-start the samba client?

• C++ DLL-Linking UnResolved Externals

  - by Undawned

  I have a rather big Core project that I'm working with, I'm attempting to adapt it to use a DLL Engine I've built, I'm getting a bunch of errors like: unresolved external symbol "private: static class When including some of the headers from the Core in the DLL, the class is exported via __declspec(dllexport) but any header with static members throws out a crapload of errors regarding the static members. This is a rather big project, I can't exactly run around removing every static class member I see, is there anyway around this kind of thing?

• Tomcat startup logs - SEVERE: Error filterStart how to get a stack trace?

  - by Benju

  When I start Tomcat I get the following error: Jun 10, 2010 5:17:25 PM org.apache.catalina.core.StandardContext start SEVERE: Error filterStart Jun 10, 2010 5:17:25 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/mywebapplication] startup failed due to previous errors It seems odd that the logs for Tomcat would not include a stack trace. Does somebody have a suggestion for how to increase the logging in Tomcat to get stack traces for errors like this?

• How can an object not be compared to null?

  - by ProfK

  I have an 'optional' parameter on a method that is a KeyValuePair. I wanted an overload that passes null to the core method for this parameter, but in the core method, when I want to check if the KeyValuePair is null, I get the following error: Operator '!=' cannot be applied to operands of type System.Collections.Generic.KeyValuePair<string,object>' and '<null>. How can I not be allowed to check if an object is null?
