Tips for shaving a few bytes off a byte array?
Hi, before you give me the standard solution using Inflator and Deflator, Im doing this on a J2ME device (of which there is no solution already implemented for both compression and decompression).
I have a few byte arrays of length 150-300 bytes and just want to squeeze things all tighter if possible. The header information for decoding them should be stored in the resulting byte[] array also.
I know storing a huffman tree would probably be too large for this so I just want suggestions for any tiny things that can be done (ie looking for repetitions of bytes or nibbles in the array)
Thanks in advance!
how large a header would I have to store in the byte
array? The arrays are very small and this header data
must be included in them!No header at all

When i try to open week cal it loads and then closes after a few seconds...I have checked for updates, turned the phone off then on, closed out of the app and then opened it again...nothing works! I have thought about deleting the app from my phone and then reloading it again but I worry that it will delete all my calendar info??? Any suggestions?
To reset, press and hold the Home and power buttons until the silver apple appears.
I would delete the app, reset the phone and then download the app again. Your calendar information should be stored on the phone as Week Cal uses the Calendar app information.
Best of luck. -
I have a 1st Gen, MacBook Pro from 2006. For the last few years I've had to us my power adaptor as my battery no longer works, and shuts down after 30 seconds it. Now my power adaptor looks like it's coming to an end. Even though it's securely fitted, it often switches off.
I am planning on buying a new MacBook Pro later this year, but for the meantime I'm not sure if I should buy a new power adaptor, or if this is a problem with my MacBook Pro. Also does anyone know where I can buy a battery in the UK for 1st Gen MacBook Pro.OWC has batteries for 1,1 generation MacBook Pros and they ship internationally - http://eshop.macsales.com/.
Your best bet for a power adapter is to get one from Apple. Third-party adapters just don't seem to be reliable (or safe). You can also buy a replacement battery directly from Apple, of course, but they're a bit more expensive.
Good luck,

Looks the company apple cannot grow if they do not support solving the problems of their existing customers

IndiaYou are not addressing Apple here. If you have a problem, describe it and someone might be able to help. Just to be sure, the wi-fi on the phone will go off after the phone goes into sleep mode unless it is actively being used. This is a battery saving measure. If you are actively using the internet, and the phone is still awake, then the wi-fi should remain connected.
What troubleshooting steps have you tried. -
my ipad will not let me slide to log in, or power off. I have tried to hold down the sleep and home button at the same time, but that did not work. D o you have any tips for me? Thanks.

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?
I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
This was my first Mac since an old Apple II GS. After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc. Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
That said, any tips?
Thanks
It does have a crack on the left of the screen case about 3/4'' up from the bottom. I've posted that as another question.Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little. -
Any tips for novel writing in Pages?
I am determined to finish my next novel in Pages. I can't take the weight of Word any more. Does anyone have any tips for using Pages in this way, producing a manuscript that will probably run to 130k words in the end? I have tried everything in this field on OS X, from Mellel to Nisus, Ulysses and Copywrite, and I think Pages suits me best.
What I have discovered so far...
Good points
Reliability
Ease of use
Speed
The fantastic search and I think unique show search feature which is now my primary way of navigating the manuscript.
Could be better
No keyboard shortcuts for styles
It's simpler to number chapters manually than mess around with lists
The word count is awkward to get at
No outlining or easy navigation by chapters
Occasionally I get red underline spelling errors for words that are spelled correctly. This goes away if I right click and may be due to hyphenation though that is turned off for the document.
G5 dual Mac OS X (10.4.2)Bodsham,
I started my novel with Nisus, switched to CopyWrite, then wrote the bulk of it with Pages. All in all, using Pages was a terrific experience. But the use of a word processor for a novelist is a very, very personal and subjective thing.
Things a novelist might like about Pages
- What you see on the screen is beautiful -- Pages renders text extremely well
- The system for defining styles is excellent. When I first fired up Pages 1.0, it took me 15 minutes to make a complete manuscript template, including headers
- It's very stable. Unlike Nisus, which was a nightmare (adding blank pages and weird indents all through the document), Pages behaves itself very well
- Plays nice with Word. I'm able to open and export Word docs very successfully
- Brilliant search feature; provides a list of word occurances, then lets you click on them
- Bookmark feature lets you easily jump from chapter to chapter
Things a novelist might not like about Pages
- A few people report a typing lag. If you experience it, it's a significant problem
- Bookmarks, while excellent, won't permanently sort alphabetically -- only numerically. Every time I open my document, my bookmarked list of chapters is sorted incorrectly. Not a big deal; just a minor annoyance
- Very mouse-intensive program. Not a huge issue for a novelist since we mostly just hit a carriage return; not a lot of styles in a text-based manuscript
- Gobbles up a lot of screen real estate. In order to have various inspectors and panes open, it's good to have a larger monitor, otherwise you'll find things sitting on top of your text
I'm sure there are many more strengths and weaknesses, but that'll get you started. By the way, you can download Devon Technologies' excellent and free Word Services that'll add a lot of very useful features (including word count) to your services menu. Get it at http://www.devon-technologies.com/download/index.html

Some Tips for Cablecard Users with HBO
I have been using a cablecard with my Hauppauge DCR-2650 digital tuner and Windows Media Center on my Windows 7 PC for 3 months with no problems on any of the Prime HD channels. I just subscribed to HBO and was not able to access any of the HBO channels, SD or HD. The message "Subscription Required" would appear after a few seconds, along with a message saying I needed to obtain a subscription to HBO. After Live Chatting to 3 techs over 3 days, I was finally able to access the HBO channels. I'm not sure this solution is permanent, but this is what I did. First I updated the firmware and drivers for my Hauppauge device. Then when I Live Chatted with the technician, he performed a "manual cablecard validation". During this process he asked for my cablecard ID, the Host ID, the Data ID and the activation code. He had me switch channels from an HBO channel to a non-HBO channel, then back again. Voila! It worked. So if my HBO disappears in the future I'll be asking for a tech who knows how to perform a "manual cablecard validation". Now I had my HBO channels in HD, but the picture was flickering a bit, enough to make it annoying to watch. After Googling "HBO HD flicker" I found that the problem was not with the cablecard or Fios, but with the graphics adapter settings. I have an integrated graphics chip on my PC, an Intel 3000 graphics chip. I opened the graphics properties page and in the "Media" category under "Image Enhancement Option" I turned off the "Adaptive Contrast Enhancement" feature. This fixed the flicker. Hopefully this post will help those few who are using a cablecard with their Home Theater PCs.

I have a 16GB 3GS phone since about20 months now. For the last few days, my phone is constantly giving me message that the accessory attached to my phone is not optimized for this iphone. You may experience noise or poor communication, while there is no acessory attached to it. I always used standard headphones and charging cable. Now when i recall, it started at one of the sync sessions with my itunes. I have turned my phone off and aon again and again but the message keeps coming every one or two minutes.I have also started loosing voicce on different applications like youtube etc. Also the ringer volume up and down key does not show me the small boxes increasing or decreasing on screen. The phone is playing crazy. Can someone help please
Thanks
ZiaIt helped earlier but it has come back again. I don't know what to do. I tried what you said earlier but this time even this is not working either. And quite intrestingly my phone won't turn off. I turn it off, it goes off and then restarts on its own and then keep giving the same message again and again.
Could it be a charging cable, is there any chance that the cable which was working fine one day could turn to be "incompatible" with iphone the other day????????

Tips for blue screen (BSOD) errors with Windows Vista and Intel Turbo Memory on X61/X61s
Important note: The symptoms and solutions described below address only a small subset of the possible causes for blue screen errors, aka BSOD.
This information can help address blue screen errors specifically
related to Turbo Memory, but may not solve errors related to other
issues. Please read through the instructions completely, make sure they
apply to your system, and after attempting the solutions please post
back with your feedback for the community.
Some users may experience random blue screen errors with ThinkPad
systems running Windows Vista with Intel Turbo Memory hardware. These
blue screens may occur during normal usage on the system or they may
occur when booting into Windows Vista. Blue screens related to the
Intel Turbo Memory hardware may reference a stop code of 8086 with
memory address locations of {0, 0, 0, 0}.
There are two main steps that you can take to help resolve blue screen issues related to Intel Turbo Memory.
Step 1: Update Intel Turbo Memory Driver
If the driver version is before version 1.0.1.1004-7.0.3.1001, please
update to this version.
To determine what version of the Intel Turbo Memory driver is installed:
1. Click Start, then click Control Panel.
2. Click System and Maintenance.
3. Click System.
4. Click Device Manager.
5. Expand the Storage controllers category.
6. Double-click Intel Flash Cache Logic Chip.
7. Click the Driver tab. Then you will see the driver version (for example, 1.0.1.1004).
The new driver and installation instructions can be found here.
Note: The Intel Matrix Storage Driver is updated with this package.
Step 2: BIOS version
If your BIOS version is older than those listed below, please update to the version listed.
How to check your BIOS version:
Turn off the system.
Turn on the system.
While the To interrupt normal startup, press the blue ThinkVantage button message is displayed at the lower-left area of the screen, press the F1 key.
The
BIOS Setup Utility menu will be displayed. If you have set a supervisor
password, the BIOS Setup Utility menu appears after you enter the
password.
Check BIOS Version and Embedded Controller Version.
Turn off the system.
System BIOS versions:
ThinkPad X61 or X61s - BIOS version 1.06 (7NET25WW)
Please
remember that these updates do not solve every possible system blue
screen, but they do resolve several problems related to the Intel Turbo
Memory driver.

X60 Tablet SXGA+ primary, Z61p fully loaded workhorseDear Tim,
First off, many thanks for the tips for resolving BSOD with Vista + Turbo Memory on X61. I've been suffering from this BSOD for countless times since I bought in my X61 7673-CW9 in April 2008.
Even prior to having the pleasure to visit this wonderful forum, I followed both steps as indicated, and updated my Intel Turbo Memory driver to 1.5.0.1013 and my BIOS to 7NETB4WW (2.14). However, the BSOD recurrs.
For the past two months, I've recovered my system to factory default settings using Rescue and Recovery for over twenty times, each time with the latest Intel Turbo Memory driver and BIOS. Notwithstanding that, BSOD recurrs.
During these painful experiences, I tried two options: 1) making my X61 up-to-date by using System Update and Windows Update (including Vista SP1 or excluding Vista SP1); 2) keeping my X61 the status as factory default (i.e. without updating through either System Update or Windows Update (the automatic/scheduled update function of both is turned off)). In either case, BSOD recurrs.
I'm 100% positive that the BSOD does not arise from any hardware or software/firmware I install. I never install any hardware (e.g. RAM). And, it is not caused by any software/firmware I install: the clear and unequivocal evidence is that at one time,I encountered BSOD while having restored back to factory setting and booting for the first time.
I live in Taiwan, and I seldom heard this BSOD here. All of my friends (as most of Taiwan residents) using X61 operate in Traditional Chinese environment, whereas I operate in English environment. In Taiwan, when booting for the first time after purchase/recovery, the Windows Vista Business system provides for lanuage choice (Traditional Chinese or English), and, once chosen, the language cannot be altered later on (unless, of course, the system is restored back to factory default settings).
My system specs are the same as the day I purchased it and are listed below (as I'm not sure if my machine type X61 7673-CW9 is applicable outside Taiwan):
Processor: Intel(R) Core(TM)2 Duo CPU T8300 @ 2.4GHz
Memory: 1.00 G.B.
System: Windows Vista Business (32-bit)
Hard Drive: 160 G.B. @ 7,200 r.p.m.
And, of course, with Intel Turbo Memory 1 G.B.
I contacted the Lenovo support staff here in Taiwan for countless times, but they seem to be clueless. I learned that some friends at this forum downgraded their OS back to Windows XP, but I chose not to. The reason is simple: my purchase price for X61 7673-CW9 includes the Intel Turbo Memory, which cannot function under Windows XP (at least so far).
Therefore, I just wish to share my experience here and perhaps I can get some advice from you and other friends here. Any advice will be tremendously and enormously appreciated.

i'm trying to use a madcatz controller on the mac but it turns on for 2 seconds and turns off. the system profiler picks it up as a xbox 360 gamepad but says its not been configured. how can i allow my self use this with my games!
I have exactly the same problem.
I'm a little peed-off with Microsoft on this. The original wireless controller I have doesn't work either since the cable I'm using is 'just' the charge and play cable, so a direct connection to my Mac won't work with this cable. It's a cable for god's sake. Why on EARTH put any limitations on this!?!?
Next I learn I need an additional USB wireless receiver from Microsoft to get my original 360 controller to talk to my Mac. As I certainly don't want to fork any more microsoft dollars on this, this is not an option.
Next I think, yes! I have a MadCatz 360 wired USB controller. This should surely do the trick just plugging it in and the way I go. But oh no, for some reason I plug my MadCatz Xbox360 controller in, it flashes a few times then switches off and can't be turned on again.
The System Profiles recognizes it as a MadCatz 360 device controller but that is about it, but the ontroller software I download for the System Prefs (360Controller, USBOverdrive etc) don't even recognize the controller as being plugged in.
What the **** Is The Microsoft Deal with all of this!?!?
PS: Oh, and I forgot to mention, there are No drivers for device 4716 that I can find on the MadCatz website, or am I going blind?
If anyone has a link, it would be appreciated.

Hopefully useful tips for endless processing
I also posted this in reply to another user, but I think it might be useful enough to others that I will post it here so it's not so buried.
I'm just starting, after many, many hours, to see the light at the end of the tunnel with Aperture 3. I think A3 offers some great options, and is a diamond in the rough -- very, very rough, even in v3.0.1.
But I think I have some VERY USEFUL TIPS for you here (again this is after a lot of learning by pain... 4 different attempts to "upgrade" my A2.1.4 library (42K images about 200GB of images).
1st, and possibly most importantly the "SHIFT" key is your friend. You can use it when you restart A3 to stop the endless processing loop that A3 would fall into every time I upgraded or imported my library to A3 (or 3.01). All you need to do is hold down the "SHIFT" key while restarting A3, this should top all previously stuck processing as you upgrade your library. So use this tip after you first upgrade/import your library, if the processing bug hits. Then you have to be patient and go though your library and figure out where the problem files are (Apple has done a LOUSY job in not identifying what specific images A3 is processing in the "Activity Window" -- Let Apple know if this really bugs you)
2nd, at this point you will need to systematically go through your library and figure out where the "problem" files are and "fix" them (in my case all of these worked just fine in 2.1.4 - go figure). I would start by generating thumbnails for all of the images in a project, one project at a time (I had 150 some in my library). When you get stuck in the "processing" loop again, you can restart A3 using the "SHIFT" trick, and maybe just try a chunk of images within that same project until you find where things fail again, and until you can get to the offending image (if it's a problem you won't be able to generate a thumbnail for the image -- and A3 will go into endless "processing" mode)
3rd, this sound like a horribly tedious process and it is. But I can offer you some useful tips. In my case, and others as well apparently, a lot of the offending files are 16-bit PSD or TIFF images, especially if they had adjustments applied in A2.1.4. In my case I had fewer than 50 of these, so I exported an original and a jpg for each of these files. I re-imported the jpg and deleted the PSD/TIFF from A3 (I kept the exported original for future use). These files would then generate thumbs without endlessly processing. The other type of file that I ran into problems with were stitched panoramic images (often over 30MP) that I had applied adjustments to in A2.1.4. I simply removed the adjustments and the generated thumbs for them (worked like a charm).
4th, download some good podcast, music or audiobook... this will take a long time.
Cheers, and look me up in FaceBook I started a group called "Apple Please Fix Aperture"Danny,
Funny you should mention this.... (actually it makes you look a bit like a "schill", even though you are not)... nope, as far as I can tell there is no way to tell which specific images are causing A3 to grind to a halt.
Hence my comment:
"(Apple has done a LOUSY job in not identifying what specific images A3 is processing in the "Activity Window" -- Let Apple know if this really bugs you)" and similar previous ones in other posts.
I wonder if Steve, yes that one, knew about this, being the perfectionist he seems to be, if he would have this feature included in Activity Monitor ASAP, or more likely it would have just been fixed by now (more of a "one-button" solution). Anyone have his house #?
In any case, I please let me (us) know if this helps resolve your problems... and consider joining the Facebook group as well and maybe we can hope for a much better 3.x.x version in the very near future.
