Free iBook G4 800Mhz. Does not work.

rajulkabir — Sat, 09 Apr 2011 17:55:19 +0800

(I know that trading is not allowed in this forum, I assume this is okay since I am giving the item away for free. I figure it's only of interest to real Apple enthusiasts).

I have a 12" iBook G4, 800Mhz. The logic board is dead (at least I think it is; it won't boot off HD or CD) and I've taken out the hard drive. It has 1GB of RAM, I believe. The case is somewhat the worse for wear, having been used everywhere from the Iraqi desert to the Himalayas of Nepal. Includes power supply, original CDs.

I figure someone might want the machine for spare parts, or experimentation, or something. If so, just PM me and it's yours.

Conditions: I am too lazy to package and post it, and too lazy to travel very far from home. So you'll have to collect it from me in KL.

TM/Streamyx choking TCP sessions after 48KB?

rajulkabir — Tue, 08 Mar 2011 22:24:22 +0800

I'm a Streamyx 4mbps customer.

Recently, I have observed that I can no longer execute scp file transfers to servers with sshd listening on non-standard ports.

If the server is listening on port 22, no problem.

If it's listening on a high port, the transfer hangs after 48KB.

I don't think it's a local firewall issue, as it occurs with my computer connected directly to the modem in bridge mode and the computer's firewall disabled. And I don't think it's a server issue, as I've configured a server to listen both on port 22 and on a high port, with identical firewall rules on the server for both ports, and I observe the same thing.

Is anyone else experiencing this? Is this part of some attempt to throttle P2P traffic? Because to me it seems like if I can't transfer more than 48KB over a TCP connection, I don't really have an internet connection, and it does not seem reasonable that I should be paying as if I did.

Google malware alert

rajulkabir — Thu, 22 Jul 2010 21:31:53 +0800

I just got an alert from Google (using Chrome browser) that the page I was trying to visit on forum.lowyat.net contained items hosted by iconator.com which was listed as a suspicious site and potential malware source. I had to click an "I accept the risks" type box to actually see the page.

You may want to check out whether you are accepting ads from shady sources. Or it could be Google's mistake.

Recommendations for service on older Mac hardware?

rajulkabir — Sat, 12 Jun 2010 03:08:36 +0800

I have two iBook G4s. One has a dead logic board and one has a failing screen. I would like someone to perform surgery on them so that the working logic board and working screen are in the same machine. This doesn't seem like the kind of thing that an official service center would do. Anyone have any recommendations for people who do this sort of work? Thanks.

Google bringing 1gbps broadband to selected towns

We're planning to build and test ultra high-speed broadband networks in a small number of trial locations ... We'll deliver Internet speeds more than 100 times faster than what most ... have access to today with 1 gigabit per second, fiber-to-the-home connections. We plan to offer service at a competitive price to at least 50,000 and potentially up to 500,000 people ... As a first step, today we're putting out a request for information (RFI) to help identify interested communities. We welcome responses from local government, as well as members of the public.

Sound like fun? Unfortunately I don't think they'll entertain requests from communities in Malaysia. But it's worth a try!

1 megabit is "a legal right" in Finland

rajulkabir — Thu, 15 Oct 2009 23:11:22 +0800

http://www.yle.fi/uutiset/news/2009/10/1mb...ht_1080940.html

As of July 2010, everyone in Finland has the legal right to 1mbps internet access, set to increase to 100mbps in 2015. If your ISP can't get you 100mbps, no matter where in the country you live, then the police will make them do it.

When we will see something like this here in Malaysia?

Wifi on the bus

rajulkabir — Sun, 29 Mar 2009 15:55:16 +0800

I'm posting this using the free wifi on the Transtar bus from Singapore to KL. It seems to be a Huawei router connected to Maxis service (for this reason it only works on the Malaysian side of the border). Not too bad actually. I think there's another bus company that also provides wifi. Odyssey maybe?

Anyone else used wifi services provided on moving vehicles? I have used the internet on the Thalys train between Paris and Amsterdam many times; it's provided by satellite so the latency is quite high and interactive sessions (e.g, SSH) are frustrating. This cell-network service on the bus seems much more responsive.

Speed test follows (taken about 15km north of the Second Link border checkpoint):

The numbers are a little weird, but I've never used Maxis, maybe that's what it's like.

Getting closer to Google

Anyone notice Google results have become much snappier recently? I think it might even have happened today.

Malaysia? India?

Malaysia ranks #75 in internet bandwidth per cap

rajulkabir — Wed, 03 Dec 2008 04:14:45 +0800

http://www.nationmaster.com/graph/int_int_...mbps-per-capita

While it has its flaws, this is an interesting way of comparing a fundamental prerequisite of internet service quality.

Denmark, ranked #1, has 34kbps per person.

Malaysia, ranked #75, has just 128bps per person, placing her behind such powerhouses of development as Gabon, Uruguay, and Afghanistan.

Singapore, at 5kbps, has 45 times as much international connectivity per person as northern neighbour Malaysia.

At least we can feel better knowing we're not living in perennially war-torn West African nation Guinea-Bissau, where each person enjoys just 0.043bps (about 2.5 bits per minute, enough to download a 650MB CD image in as little as 4020 years).

Malaysian carriers to reduce ASEAN roaming rates?

rajulkabir — Sun, 05 Oct 2008 16:01:35 +0800

QUOTE

Roaming charges for mobile phone users in the Asean region may be cut by as much as half early next year.

Energy, Water and Communications Minister Datuk Shaziman Abu Mansor said a reduction was necessary as the present charges were ex cep tionally high for users in developing countries.

“We plan to reduce roaming charges with Singapore first. In fact, I told the Malaysian Communications and Multimedia Commission (MCMC) two weeks ago to proceed with this,” he said in Kampung Tanjung Rantau near here yesterday.

...

Asked what was the acceptable rate for roaming charges, Shaziman declined to say but added: “If you ask me, anyone making a call from JB to Singapore should be charged a local rate. But let the MCMC and the telcos come up with an acceptable structure.”

TMnet blocking sites?

rajulkabir — Thu, 28 Aug 2008 15:47:26 +0800

I noticed today that TMnet is not serving up DNS for malaysia-today.net. Works fine if using non-TM DNS server.

Turns out to be a CNAME for mt.harapanmalaysia.com. And that IP is not blocked.

But this makes me wonder. Are they deliberately doing a bad job of blocking? Or are they just incompetent. I mean, I know they're incompetent, but are they THAT incompetent? I would assume they'd at least force them to start hopping IPs. So maybe it's deliberate, in which case I'd finally have to give TM some credit.

Universities giving iPhones to students

rajulkabir — Sat, 23 Aug 2008 05:27:37 +0800

QUOTE

Taking a step that professors may view as a bit counterproductive, some universities are doling out Apple iPhones and Internet-capable iPods to students.

The always-on Internet devices raise some novel possibilities, like tracking where students congregate. With far less controversy, colleges could send messages about canceled classes, delayed buses, campus crises or just the cafeteria menu.

While schools emphasize its usefulness — online research in class and instant polling of students, for example — a big part of the attraction is, undoubtedly, that the iPhone is cool and a hit with students. Basking in the aura of a cutting-edge product could just help a university foster a cutting-edge reputation.

...

“We think this is the way the future is going to work,” said Kyle Dickson, co-director of research and the mobile learning initiative at Abilene Christian University in Texas, which has bought more than 600 iPhones and 300 iPods for students entering this fall.

Although plenty of students take their laptops to class, they don’t take them everywhere and would prefer something lighter. Abilene Christian settled on the devices after surveying students and finding that they did not like hauling around laptops, but that most always carried a cellular phone, Dr. Dickson said.

Australian wimax provider shuts down network

rajulkabir — Mon, 24 Mar 2008 01:36:45 +0800

Interesting article. After his company built out a Wimax network, they discovered that coverage indoors was very poor and the latency was too variable to support VoIP. He calls the technology hype and says it has failed to provide what it promised.

http://www.commsday.com/node/228

Of course it's possible that his staff or his supplier was incompetent, but the article's author was unable to come up with anyone making that claim.

I wonder if this will be of interest to MCMC, which seems to be pushing wimax as a way to avoid facing the number one problem with Malaysian broadband policy: TMnet's monopolisation of the copper infrastructure that all Malaysians have paid for.

Many people seem to feel that wireless is some sort of magic solution to access problems, without understanding that it will always be slower and less reliable than wired.

Moving house... how long to move Streamyx?

rajulkabir — Thu, 28 Feb 2008 17:26:10 +0800

Moving house soon.

I stopped by TM Point an hour ago and asked them what the process is for moving my fixed line and Streamyx to the new place.

She told me it would take two weeks!!!

In other countries where I've lived (Asia, Middle East, Africa), the cutover has taken a few hours at most. In some countries they provide service at BOTH locations for 24 hours on the day you switch - number rings in two locations at once - so you are never out of contact.

And TM needs two weeks? What kind of insanity is that? Why would they deactivate the old service two weeks before activating the new one? It makes no sense.

It took only a few days to get it activated in the first place. Yes, she said, it's much faster to cancel and order new service than to move existing service.

Is this really true? Does anyone have experience with moving their line - how long did it take? I'm in central KL if it makes a difference.

Asterisk/Telekom terminology question

rajulkabir — Tue, 05 Feb 2008 15:57:41 +0800

I'm trying to set up an Asterisk system. It worked perfectly in KL, but when installed at its final location in Subang, there is a problem because the Telekom switch is not properly signalling the end of incoming calls.

Normally, after the end of an incoming call, the Telekom should switch drop the current for a fraction of a second so that the customer's equipment knows the call is over.

But this doesn't seem to be happening on these lines in Subang. The only indication that the calls is over is a busy tone, which of course is a very unreliable way to detect a hangup.

I have spoken with many people from Telekom but none of them even understand what I am talking about. I think there is a language problem at play.

So I wonder if anyone can tell me the technical term that Telekom uses for this (normally I would refer to it as "disconnect supervision" or "calling party control" or "open loop disconnect").

Or if anyone could point me to a forum where telecoms in Malaysia are discussed in technical detail, that would also be great. I haven't been able to find anything online, but then again I am only searching in English.

Co-location: Where

rajulkabir — Fri, 18 Jan 2008 01:49:09 +0800

I need to find a place to put a server. It has to be in the region because I need low latency to Malaysian IPs.

Right now seems to be a good time to look into this, since at the moment Streamyx is pharked and is getting 800ms+ to everywhere outside of Asia and Australia. This means I can see how things work under all-too-common bad conditions.

So I looked up a bunch of Malaysian colocation providers in Google and tried pinging their web servers, on the theory that they would be eating their own dogfood.

Every single one that I tried gave me EITHER bad pings from Streamyx (45ms one ping, 130ms next ping), OR bad pings from USA (500ms+).

But then I noticed that all the Singapore colocation providers, no matter how homemade their web sites looked, have good pings from Streamyx (steady 55ms) and from USA (steady 260ms).

So does it make more sense to just go to Singapore? Does anyone have experience with Singapore colo houses? Or Malaysian ones for that matter?

Network reliability is my main concern here. Cost is secondary. If there is a monthly traffic limit I would prefer that it approach 1TB.

Asterisk skills

rajulkabir — Fri, 21 Dec 2007 02:46:40 +0800

I am considering setting up an Asterisk server as a favour to a friend here in KL. His company has esoteric telecom needs and the old Panasonic key system they have now isn't cutting the mustard.

However, I travel a lot, so if problems came up, I wouldn't always be around to help him out. Normally I avoid getting into these situations unless I can be sure I can offer backup support somehow.

So I wonder, is there a community of Asterisk users here in Malaysia? How to hook up with them? Has anyone had experience with any local Asterisk integrators or support providers?

Original xbox

I want to buy an original (not 360) x-box. Where can I find one? Tried ebay and lelong.com.my, no luck. I figured there would be lots of them lying around in closets and storage rooms.

New benchmark for Wawasan 2020

rajulkabir — Thu, 25 Oct 2007 02:57:20 +0800

I know everyone loves these posts about super-duper broadband in other countries...

Here's the real 2020: Verizon in the USA is now offering 20/20 (20 megabit up, 20 megabit down) residential fiber for US$65 (RM225) per month.

http://newscenter.verizon.com/press-releas...-fast-with.html

I tried to check whether my address in KL was eligible, but the page here: http://www22.verizon.com/Residential/ didn't recognise my 03 number. On the other hand, the woman in the photo looks like she could be Malaysian (reload until you get the one sitting with a laptop on the couch).

I don't think they have that upload speed even in Japan (but I could be wrong).

The vanishing internet

rajulkabir — Thu, 14 Jun 2007 01:51:17 +0800

Has anyone else experienced a sudden disappearance of huge swathes of the internet as seen via Streamyx today?

There are scores of IP addresses (I am finding more every few minutes) that I just can't reach. In some cases it's even different IP addresses on the same server - one will work and the other is unreachable.

If any one IP in a subnet is unreachable, then the entire subnet (as I see it via BGP) is, with the same symptoms.

If I try to ping or traceroute any of the problem addresses, I get a routing loop at 203.106.225.29, which is a TMNet router. Maybe they are using a ZTE ZXDSL for their backbone and its 64KB routing table is full.

Just for sport, I rang up 1300 88 9515 but of course they had no idea what I was talking about and were all into resetting my DSL circuit. I said, "no, it's a routing problem, has nothing to do with my DSL circuit", then he tracerouted my Streamyx IP and proudly announced that the routing was fine.

It's really very frustrating trying to deal with them. Is there no way to get someone on the phone who knows anything?
