Want Security?

2006-07-05 rolfje No Comments

According to Sophos security, the whole world should switch to macs to get rid of the security problems. This would be great for business! Currently I do not order with companies who put up Word or Excel formatted price lists, simply because I can’t (and to some extent refuse) open them.

In the long run however, this would shift the security problem to the Mac side of the world. Why do Microsoft machines get attacked so often? Simple: because their user base is large, which means there are more Microsoft (black hat) hackers out there. Additionally, the targeted audience is large in numbers. When the whole world uses Macs, the black hat hackers will turn to OSX as target.

But then again, the security model of OSX is (luckaly) a lot better than that of a Windows machine so the damage done largely depends on how the system is secured by the user. At least on a Mac you have the means of securing stuff properly.

MP3 Gain for OSX

2006-06-21 rolfje No Comments

So here I am using iTunes on my Apple. So far so good. The downside is that I have an iBead as an mp3 player, so there are a few problems with that. First of all, iTunes only plays nice with the iPods (and a few other oddballs ;-). For me to put mp3’s on my iBead, I can drag them over from iTunes onto the USB drive, but when things’ don’t fit, it just doesn’t copy at all. Also, automatic random playlists aren’t that automatic.

So far, I can live with all these little problems. I can create a playlist limited to a particular size, empty my iBead and drag the mp3’s over. But when I play them on my iBead, the volume levels are far apart. In the old days I used mp3Gain on my PC to level out all volumes, which worked great. But iTunes has it’s own take on that: It stores a relative volume in the file, and iPods know how to handle this properly, adjusting the volume. My iBead however, doesn’t.

Tonight I went out to look for a tool which could adjust the volumes of my mp3’s on my Mac mini. And guess what? I found it! MacMP3Gain does it all, and it is currently processing my complete library, adjusting all volumes. It has a “nice” option so it won’t hog all processing power. I think it will be finished somewhere tommorow afternoon. It claims to be lossless, so I guess I can run it on my complete library every once in a while without having to worry about which files are new or not.

Photo Statistics

2006-06-21 rolfje No Comments

I am trying to decide what lens to buy for my Canon EOS 350D. The first descision to make is what focal length I need. To do this, I found a nice tool which can display statistical info about your photographs. It shows you how many foto’s you’ve made at certain focal lengths, with which aperture, ISO, metering, and other EXIF fields. It’s a windows only tool, and it’s called Smart Photo Statistics. It’s absolutely 100% free software and works as expected. It can even copy the graphs to the clipboard for you to use elsewhere.

I’m gathering statistics right now on all photo’s of all digital camera’s I’ve owned, to see what focal lentgths I need. Great tool!

Canon 350D B/W Sepia

2006-06-03 rolfje No Comments

Once in a while I like to take black and white pictures because the EOS has a nice built in set of color filters. The easiest example of a nice black and white photo where a color filter produces great results is the classic “blue sky with Yellow filter”. You should really check out the great tutorials on Cambridge in Color.

350D Sepia

When shooting in B/W mode, I often use the “sepia” filter, to add a little warmth to the photo. A wierd thing I noticed lately about the EOS 350D (besides the film transport sound) is that “Sepia” mode is not really producing pure B/W Sepia images. There is color seeping through! In the top image, you can clearly see residues of red, yellow and blue in a photo of a baby toy (cropped for privacy reasons). The bottom image is converted to pure B/W on a computer and then sort of “Sepia”-d using a hue/saturation tool just for reference.

I read on some forums that camera effects are generally not as good as the effects in image processing programs like PhotoShop or GIMP. This is supposedly because speed/quality tradeoffs. I really like to spend more time with the camera than post-processing, so I’d like to keep using the in-camera effects. A great tip I read somewhere on a forum is to shoot in RAW+JPG mode. The JPG will have all the processing done by the camera, and the RAW will be the raw data from the sensor. Depending on the results of the in-camera effects, you either keep the JPG, or use the RAW image to do the effect in GIMP later on.

Finding double entries in iTunes

2006-05-23 rolfje No Comments

The Mac has been on for the past few days, even with the Maxtor FAT32 250GB drive connected, without problems. I hope it doesn’t break down again, because I’d have to bring it to a different Mac store and explain the whole thing again… Anyway, I was playing with iTunes and found a simple trick to find double entries.

Open a Terminal, go to the root of your iTunes music collection folder and type
find . -name "*1.mp3" -type f

This will give you a list of all tracks ending with “1.mp3”, which is how iTunes renames double-entries. Do not look at the filenames, but rather select the artist in iTunes with the double tracks, and use the “show double entries” in iTunes to do the rest.

It isn’t much, but it saves you the trouble of finding double tracks in your 8 zillion tracks 😉 .
Have fun!

Mac Drama Day

2006-05-20 rolfje 1 Comment

Mac Support guy on the job in Uitgeest So, finally the first post on my blog since 2 weeks of Mac absence. I really got annoyed by the repair guys at Mac support the past few days. I started calling them daily, and discovered if you don’t, your repair just simply will sit there on a shelf. For some strange reason, they ordered a superdrive for my Mini, the guy on the phone promised me he would install it on friday as soon as he got it. So I called in friday afternoon to see how things are going, and guess what? The drive was in, but not in my Mac! They promised me they would install it and call back. You guessed it: they didn’t.This mornig I decided to drive over there, because they essentially promised it would be ready yesterday. Although nobody called me, apperantly the repair was done, and I could take it home. On the receipt it said “superdrive and memory swapped, hardware test, everything ok”. So I took it home, connected it and booted it in single-user mode. Since my trust in these guys had dropped to an all-time low, I decided to run at least 3 full memtests. At the very first run, it failed, with the exact same error as two weeks ago. I was furious! Not only did they take 2 weeks to swap out a non-faulty superdrive, they didn’t swap the memory, although they lied on the receipt about having done so!

So, I put it back in the box, to spend another half hour driving to Uitgeest. I demanded that the mini was repaired while I was waiting. Suddenly, there were tech-guys available, although they claim to do no repairs on saturday. Wierd. I spent an hour waiting, and a young kid comes to ask me for my password, can you beleive that? You can’t do that! Besides, they just spent 2 weeks repairing it without ever needing my password, and now they do? I explained to him that he didn’t need my password to run memtest, and that I wasn’t planning on giving it to him. Back to the repair desk he went.

Behind me in line there was a lady who wanted to pick up her “repaired” ipod (they don’t repair those, they just keep yours in for 2 weeks and then give you a new one). The tech guy said that nobody called her, and she replied (insulted) that she did speak to one of the guys and he was very clear on the phone about the ipod being ready to be picked up. After 20 minutes of walking around and talking to eachother the techguys “suddenly” found the ipod, and gave it to her.

During my waiting I constantly noticed how other people were also treated like I had been treated: Polite, but slow, and constanly making excuses about the slow cash register, the stupid network, how a collegue forgot to to this-and-that in the system, etc. etc. But it always resulted in a long wait for the customer. It is clear to me that the macsupport store has to do something about both their technical and people skills.

Finally my Mac arrived, and the guy said he swapped the memory modules. I said that those were allready swapped. He denied, and I showed him the receipt. He mumbled something about a faulty batch of memory modules, and shoved the box in my direction, making it clear that he did not know what to do with that information. I asked if I could test the Mac, because I didn’t feel like going home only to discover the problem was still not solved. He said he couldn’t do that. I asked him to run memtest for me. He said he wasn’t allowed to run non-apple approved software. He refused to get his boss when I asked him to.

I walked to reception, and asked for the manager. The manager had left, but I talked to his backup about this problem. She also couldn’t do much, as there was a music event going on in the store, and it was crowded. I explained to her that if I got home to find out the Mac was still defective, I would call the show owner on monday. She politely answered my questions, wrote down my name and off I went again.

At home, I booted the mac in single user mode (again) and ran memtest (again). While it ran, I noticed that the last receipt I just got, describing the memory module swap, looked funny. I had been given more expensive memory modules… huh? And on the first repair note, there was only a typed remark “swapped memory”. Strange. Memtest completed 3 runs without errors, as expected. It is now 17:08, and I have been driving back and forth between my home and the shop, and waiting at the shop since 10:15 this morning.

My conclusion is that they started the HW test, and it crashed while doing the superdrive diagnostics. The crash was not actually caused by the superdrive, but by the software hitting the memory softspot. They swapped out the superdrive and wrote a silly comment about the memory to keep me happy, while actually never touching those modules. That’s why I got the exact same error this morning. When they actually did swap the memory modules this afternoon (like I asked them to do 2 weeks ago) the problem was gone.

I bought a Mac because I was tired of my PC crashing, but the pas two weeks I have experienced something worse: repair people who are polite but slow, refuse to listen, understand and do what you ask them to, don’t return your calls, and give you your hardware back — unrepaired.

I hope I don’t have to bring in more Apple stuff for repairs anytime soon…

Mac Support… is… slooowww

2006-05-16 rolfje No Comments

As you’ve probably read, my brand new Mac Mini has a memory problem. I have brought it in for repair, but I am “slightly irritated” by the speed at which the guys from the www.macsupport.nl stores pick things up.

Friday, May 6th:	I’ve found out that the mini has a consistent, reproducable memory problem. I suspect a technician could even tell which of the two memory modules it is judging from the faulty address (faulty single bit even, for the technical readers amongst us). It’s late in the evening so I have to wait for the next day to call. I printed out a screenshot of the memory error and location, and put that in the box with the mini, to make sure they have a clear problem description.
Saturday, May 7th:	Started calling the shop. They state that the tech support guys are not in on saturday. Strange, since they installed the memory modules on a saturday when I bought the thing. Can’t the same guy swap out both modules so I have my machine back? Finding out which module is faulty can be done in the shop without me waiting. No apperantly not. I tried to call 3 of their shops, of which Amsterdam didn’t even return my call even though I asked the operator to tell them to call me back.
Sunday, May 8th:	Although the shop in Amsterdam claims to be open, they are to busy to pick up the phone.
Monday, May 9th:	I tried to call the new shop in Haarlem, but I get a “Sorry all lines are busy” message all day. At the end of the day I decide to drive to the shop. The shop is open, but they have network and phone problems (thanks to KPN, they claim). Because it is a new shop eveybody is uncertain as to what to do, and it takes me 45 minutes (!) to get the Mac mini to be taken in for repairs, even though I was helped the moment I entered the shop. They warn me that the repair is going to take a week (!).
Tuesday, May 16th	Still no call from the shop in Haarlem. When I try to call, I notice they still have the same phone line problems. So, I drive to the shop again to find out how the repairs are going. They in form me that my Mac is “scheduled for repair on the 19th”!. So it has been sitting there for almost 2 WEEKS! And then they haven’t even begun to look at the problem. They expect it to be repaired and ready to be picked up at Monday, May 22nd at the earliest.

As you can read, this is not a happy start of my 1600+ euro Apple adventure. I really hope they can get their logistics and repair process in shape. I really like the Mac mini, but I sure don’t like the way Mac support takes their time to switch to memory modules and run a diagnostics tool.

Mac Mini Crash: Maxtor not the problem

2006-05-06 rolfje No Comments

Memtest In my last post, the Maxtor OneTouch drive was the prime suspect of the spontanious crashing of the Mac. Tonight the Mac mini crashed again, but this time without the Maxtor connected to it. So I set out to do a thourough memory test in single user mode, running memtest. And after a few iterations it was there: The dreaded memory failure. I guess I have to bring my mini back to the store to get replacement memory.Intermitting problems like this are terrible. They are hard to find, and you loose all trust in your computer, saving every 3 seconds, hoping you don’t loose anything. If the external drive was really to blame, I would seriously have doubted the implementation of the USB drivers, because the system crashes without warning, without logging or anything. A memory failure was actually the more plausible casue all the time, since the kernel just stops because the processor(s) reach a part of the memory where there was supposed to be code, but has become garbage. To be able to log, the processor has to execute code.

Mac Mini Crash: cause located

2006-05-04 rolfje 1 Comment

Windows screenshot showing Maxtor drive stats Today I spent some more time using Google to find information on why my Mac suddenly crashed. I am now 99% that the cause of this all is my Maxtor OneTouch 250GB drive, which was formatted as one big Fat32 partition (screenshot). Although I connected it to a friend’s iMac for a short period without problems, and it has worked on my Mac mini for a while, I keep finding discussions about people with crashed Macs. I have not installed the Maxtor software, so that’s not the problem.I have disconnected the Maxtor drive last Saturday, and my Mac has been up and running ever since, without problems. I can almost rule out memory related issues, because when I startup Eclipse while running iMovie, iDVD, Thunderbird, Firefox, iTunes, Clutter and TextWrangler (yes all at the same time), the system keeps on running. In fact, it is still responding to user input as if I had only one of those programs running. Only very minimal swapping with 2GB memory, and when swapping, OS X is very efficient about it.

Now, my plans are as follows:

Only connect the maxtor to a PC while it is still Fat32.
Share the drive on the PC, and try to empty it as much as possible (move data to Mac and the fileserver)
Run Rember in single user mode for a few iterations this weekend to rule out memory problems.
Decide on a filesystem to use on the Maxtor, and reformat it.
Re-connect the Maxtor OneTouch to the Mac and see if the gremlin is killed.

It is very likely that the drive is going to be formatted with the “Mac Os Extended” filesystem, but I’m not sure about journalling yet. The disadvantage of all this is that the drive can not be used to transfer files between a PC and a Mac.

Still it feels funny. Some people actually can create 100GB+ Fat32 partitions they can use on their Macs. I can read and write to the drive too, but at some point my Mac decides it has been enough and kills itself (probably after finding the windows crud 😉

Sorry for the linking-frenzy, I had a lot of links I wanted to share with you.

Dodenherdenking (2)

2006-05-04 rolfje No Comments

Vorig jaar heb ik mij aardig druk gemaakt over de abnormale manier waarop steeds meer mensen met dodenherdenking omgaan. Dit jaar was mijn ervaring gelukkig een stuk prettiger. Ik heb een klein stukje van de herdenking op de dam gezien, en dat was duidelijk een stuk beter dan vorig jaar. De taptoe werd foutloos en netjes geblazen, zelfs toen er (hoorbaar) iets omviel. Chapeau. Ook het inzetten van het volkslied waarbij mensen spontaan mee begonnen te zingen was erg goed om te horen.

Na de herdenking ben ik overgestapt op de uitzending vanaf de Grebbeberg. Minder (geen) toespraken, een stuk beter. Van mij mag het commentaar bij de uitzending ook nog weg, dat past beter bij het “geen toespraken” beleid en zorgt ook voor minder gewauwel “kijk er staan veel mensen”… Ja dat zie ik! Geluid uit, en probleem opgelost.

Nee (nogmaals) ik ben geen herdenkinsfanaat, maar ik vind dat mensen wel weer eens wat meer op hun gedrag, respect en elkaar mogen gaan letten. Bijvoorbeeld: Prachtig als je op je blog schrijft dat je je irriteert aan aggressieve weggebruikers, maar geef je ook het goede voorbeeld als je in je auto zit?

Ok, genoeg gezeurd. Zennnn.
