Hacker's ramblings

I had a chance to see what an E5577 is about. I don't own this, so I didn't break it apart. A Huawei E5577 is your run-of-the-mill Android-based 4G/3G/2G to Wi-Fi router. It even looks like a cell phone:

On the outside

Enough specs, let's look at the thing a bit closer. On the front, there is a small LCD-screen and a power button. On the bottom edge, there are couple of connectors:

Charger is (per Chinese standard) an USB-connector. Micro-a to be specific. Under the flip-cover, there are two TS9-connectors for optional external antennas. Two, as LTE MIMO requires.

On the top side of the router, there is a button:

That button is used with power-button (when power is already on), to navigate the screen menu:

Doing an even remote usable UI with two buttons only is ... stupid? impossible? ... erhm... difficult. But the obvious benefit is, that you can do at least some settings and see some information without logging into the thing. For non-Finnish readers, the menu says: Back (Takaisin), Device information (Laitteen tiedot) and Wi-Fi bandwidth (Wi-Fi kaista).

Normally, the screen has following status information:

In the inside

When back cover is popped, the thing looks like this under the hood:

The battery-pack is taking most of the space there. That's smart to put a 3 Ah Li-po battery for maximal usage time. When the battery is lifted, all the good stuff is visible:

On the top right corner, right next to the 4 battery pins, there is the SD-card slot. On an initial glance, it looks a lot like 2nd SIM-slot, but as you can see, there are 8 pins in a nice row. So, that's for SD-card. Below the empty SD-card slot, there is the 6-pin SIM -slot. It is already populated, as I was studying a router, which as actively used.

Web UI

Admin-interface is a Huawei classic http://192.168.8.1/

Since the WPA-password was clearly visible on the status screen, and this router is very easy to install to your home. Sales clerk had installed the SIM-card in the store, and at home you just kick the power on, and plug in the charger. That's very much a fire-and-forget thing. On my first login, I was greeted by:

Yes, the Huawei admin / admin -pair was in use there. Since, this wasn't mine, I didn't go change the password. Also the admin-console is only accessible from LAN-side, so it isn't that much of a security hole there.

In the main screen, very little surprises to anybody who has seen an E5186:

This unit was customized for TeliaSonera Finland and it has 3 languages to choose from: English, Swedish and Finnish.

Some firmware details:

The network settings were also exactly like an E5186:

At this point I was pretty sure, that an E5577 is just a miniature E5186.

The device details are:

As you can see, there are plenty of options to go change. I just didn't present all of them here. Very little interesting stuff there.

AJAX API

Since E5186 has a very good AJAX interface for the GUI, and this is just a miniature version of it. This had to have the same:

I even ran some queries just to test it:

/api/device/signal:
<pci>96</pci>
<sc></sc>
<cell_id>36657366</cell_id>
<rsrq>-7dB</rsrq>
<rsrp>-108dBm</rsrp>
<rssi>-79dBm</rssi>
<sinr>2dB</sinr>
<rscp></rscp>
<ecio></ecio>
<mode>7</mode>

Everything I threw at it returned exactly similar results, than E5186. Which of course is a very good thing.

Final words

This was a very pleasant exploration to a familiar device. I have really nothing negative to say about this router.

As I just pulled this from my article-queue, I had a chance to do some follow-up with the owner. She said, that it had been performing well and no issues had been encountered.

Earlier last year I was playing around with a ZTE MF910, which is a exact competitor for Huawei E5577. The MF910 isn't a robust box on a long run. Occasionally it loses the 4G-connection and requires some Tender/Love/Care to kick it back on-line. On my tests, it was an ok piece of plastic, but obviously non-computer users don't want to mess aroud with their hardware, they just want it to work when needed. The ZTE's box won't deliver on that.

Given a E5577 and MF910, having exactly the same price and all, my choice would be the Huawei.

As Linux system administrator every once in a while you need to install something requiring Java. Open-source guys tend to gear towards OpenJDK, the GPL-licensed version of java. Still, java developers tend to write a lot of crappy code requiring a specific version of run-time-engine. So, you're in a desperate need of Oracle's java.

Now the Oracle people are very keen on you accepting their license before you can get your hands on their precious, leaky, JRE. At the same time all you have in front of you is a Bash-prompt and you're itching to go for a:

wget http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jre-8u74-linux-x64.rpm

Yes. Everybody has tried that. No avail.
All you're going to get with that is a crappy HTML-page saying, that you haven't approved the license agreement and your request is unauthorized.

Darn!

But wait! There is a solution! All the Oracle is looking to see is a specific cookie oraclelicense set with a value accept-securebackup-cookie.

So, to leech the file into your box, you can do a:

wget --header='Cookie: oraclelicense=accept-securebackup-cookie' http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jre-8u74-linux-x64.rpm

Ta daa! No you're rocking.

As anybody ever attempting to use mod_rewrite knows, that it is kinda black magic. Here are couple of my previous stumbings with it: file rewrite and Ruby-on-rails with forced HTTPS.

The syntax in mod_rewrite is simple, there aren't too many directives to use, the options and flags make perfect sense, even the execution order is from top to down every time, so what's the big problem here?

About mod_rewrite run-time behaviour ...

It all boils down to the fact, that the directives are processed multiple times from top to down until Apache is happy with the result. The exact wording in the docs is:

If you are using RewriteRule in either .htaccess files or in <Directory> sections, it is important to have some understanding of how the rules are processed. The simplified form of this is that once the rules have been processed, the rewritten request is handed back to the URL parsing engine to do what it may with it. It is possible that as the rewritten request is handled, the .htaccess file or <Directory> section may be encountered again, and thus the ruleset may be run again from the start. Most commonly this will happen if one of the rules causes a redirect - either internal or external - causing the request process to start over.

What the docs won't mention is, that even in a <Location> section, it is very easy to create situation where your rules are re-evaluated again and again.

The setup

What I have there is a classic Plone CMS setup on Apache & Python -pair.

The <VirtualHost> section has following:

# Zope rewrite.
RewriteEngine On

# Force www
RewriteCond %{HTTP_HOST} !^www\.thehost\.com$
RewriteRule ^(.*)$ http://www.thehost.com$1 [R=301,L]

# Plone CMS
RewriteRule ^/(.*) http://localhost:2080/VirtualHostBase/http/%{SERVER_NAME}:80/Plone/VirtualHostRoot/$1 [L,P]

Those two rulres make sure, that anybody accessing http://host.com/ will be appropriately redirected to http://www.thehost.com/. When host is correct, any incoming request is proxied to Zope to handle.

My problem

Somebody mis-configured their botnet and I'm getting a ton of really weird POSTs. Actually, the requests aren't that weird, but the data is. There are couple hunder of them arriving from various IP-addresses in a minute. As none of the hard-coded requests don't have the mandatory www.-prefix in them, it will result in a HTTP/301. As the user agent in the botnet really don't care about that, it just cuts off the connection.

It really doesn't make my server suffer, nor increase load, it just pollutes my logs. Anyway, because of the volume, I chose to block the requests.

The solution

I added ErrorDocument and a new rule to block a POST arriving at root of the site not having www. in the URL. 

ErrorDocument 403 /error_docs/forbidden.html

# Zope rewrite.
RewriteEngine On

RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{HTTP_HOST} ^thehost\.com$
RewriteRule ^/$ - [F,L]

# Static
RewriteRule ^/error_docs/(.*) - [L]

# Force www
RewriteCond %{HTTP_HOST} !^www\.thehost\.com$
RewriteCond %{REQUEST_URI} !^/error_docs/.*
RewriteRule ^(.*)$ http://www.thehost.com$1 [R=301,L]

# Plone CMS
RewriteRule ^/(.*) http://localhost:2080/VirtualHostBase/http/%{SERVER_NAME}:80/Plone/VirtualHostRoot/$1 [L,P]

My solution explained:

1. Before checking for www., I check for POST and return a F (as in HTTP/403) for it
2. Returning an error triggers 2nd (internal) request to be made to return the error page
3. The request for the error page flows trough these rules again, this time as a GET-request
4. Since the incoming request for error page is (almost) indistinquishable from any incoming request, I needed to make it somehow special.
5. A HTTP/403 has an own error page at /error_docs/forbidden.html, which of course I had to create
6. When a request for /error_docs/forbidden.html is checked for missing www., it lands at a no-op rewriterule of ^/error_docs/(.*) and stops processing. The Force www -rule will be skipped.
7. Any regular request will be checked for www. and if it has it, it will be proxied to Zope.
8. If the request won't have the www. -prefix will be returning a HTTP/301. On any RFC-compliant user agent will trigger a new incoming (external) request for that, resulting all the rules to be evalueat from top to bottom.

All this sounds pretty complex, but that's what it is with mod_rewrite. It is very easy to have your rules being evaluated many times just to fulfill a "single" request. A single turns into many very easily.

The problem

Ok. Microsoft has amped up their "upgrade now" campaign to a ridiculous level.

First Microsoft Marketing chief Chris Capossela "warned" about Windows 7 being insecure. Warned in quotes because my initial reaction was: "Oh really!? Is it really possible, that a Windows can not be secure operating system."

While this machine is eligble for a free Win 10 upg, I just don't want to do that yet. I will upgrade eventually, but at the time I choose, not some ignorant corporate chose for me. So, Mr. Capossela explained that users who choose Windows 7 do so “at your own risk, at your own peril” and he revealed Microsoft has concerns about its future software and hardware compatibility, security and more.

Now the latest development is, that Windows 10 upg is a recommended update as they're now aggressively pushing Windows 10 upgrades. Meaning, that have to actively dodge it every time I'll upgrade this box of mine.

Further details about KB2952664 a Compatibility update for upgrading Windows 7 patch @ Softpedia article.

The information

The annoyance looks like this:

In the process list of the victim machine, there is a GWXUX.exe producing that. Actually there are other GWX-prefixed processes capturing your machine, but for the sake of this blog post I'm ignoring that crap.

Ages ago Microsoft release KB article ID 3080351, How to manage Windows 10 notification and upgrade options. It contains all kinds of useless information about modifying registry entries like HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade value ReservationsAllowed.

What the article doesn't mention is, that it also hijacks your disk space at C:\$Windows.~BT and C:\$Windows.~WS. I got a tip from an article and found 5 GiB of crap already loaded to my computer. I ran cmd.exe (with administrator credentials) to free up my SSD-space:

C:\Windows\system32>attrib -h "C:\$Windows.~BT"
C:\Windows\system32>attrib -h "C:\$Windows.~WS"

C:\Windows\system32>cd "C:\$Windows.~BT"
C:\$Windows.~BT>takeown /f . /R /D Y
C:\$Windows.~BT>icacls . /grant Administrators:(OI)(CI)F /T

C:\Windows\system32>cd "C:\$Windows.~WS"
C:\$Windows.~WS>takeown /f . /R /D Y
C:\$Windows.~WS>icacls . /grant Administrators:(OI)(CI)F /T

After doing all that, reading all the information, changing all the registry values and removing pre-loaded waste...   It didn't work. What the article doesn't mention, that one of the GWX-processes runs in background and snoops those registry values and changes them back! Yes. You read it right. The fuckers go to your computer and make better choices for your registery. Their flawed reasoning is, that you obviously have to be some sort of moron not to go for their ultimate product right now, or preferably yesterday. And as you (the moron), the owner of your computer running a lesser "insecure" OS, need Microsoft's help to make better decisions.

OH, COME ON! Not cool.

I'm NOT upgrading to Windows 10 yet, because I (as in me) am in control here. Not Microsoft (as in them).

The solution

After spending countless hours and experiencing a number of setbacks, when the timers kicked on I stumbled into somebody having exactly the same problem as I do. He also had a solution for it. Here is the article Using GWX Control Panel to Permanently Remove the 'Get Windows 10' Icon.

GWX Control Panel looks like this:

With this application, no need to game of Whack-a-Mole anymore. The not wanted and not needed crap will just fly out with a click of a button. Example of getting rid of pre-loaded Windows 10 installation files:

Ultimately the cleaned up machine will report:

List of goodies include:

• Is 'Get Windows 10' icon app running? App not found
• Is 'Get Windows 10' icon app enabled? App not found
• Windows 10 Download folders found? No

Oh yes!

The application has an option to stay as a background process to keep monitoring, that evil Microsoft processes stay gone. I didn't test that, as just kicking all the crap out of my computer did the trick. Now I was back on the drivers' seat. Now I can decide when to do the upgrade.

Guess what happens right before hell freezes over? Your weather station indicates dew point of 136 °C. Kinda funny.

Good thing that Weather Underground allows you to edit by removing data points. So, there are couple gaps in my graphs now:

The reson for this weird behaviour can be found from the spec:

OMG! The lower bound of outside temperature measurement is -29.9 °C. In Finland that can be reached occasionally.

Fortunately I'm using open source software, Open2300. With very little debugging I found the code:

double temperature_outdoor(WEATHERSTATION ws2300, int temperature_conv)
...
return ((((data[1] >> 4) * 10 + (data[1] & 0xF) +
          (data[0] >> 4) / 10.0 + (data[0] & 0xF) / 100.0) - 30.0));

double dewpoint(WEATHERSTATION ws2300, int temperature_conv)
...
return ((((data[1] >> 4) * 10 + (data[1] & 0xF) +
          (data[0] >> 4) / 10.0 + (data[0] & 0xF) / 100.0) - 30.0));

There is a formula to convert raw data read from RS-232 -line to celsius.

There I introduce a hard-limit of  TEMPERATURE_OVERFLOW and check if that has been reached. If yes, the invalid value is not sent to WUnderground.

I've contacted the author of Open2300 about this, but haven't received a response.

Typical firmware upgrade for any entwork applicance is done via web-interface. The obvious catch in that is, that you need to authenticate, move to a suitable page and upload a file to accomplish that. In rare cases, hardware has an "upgrade mode", which allows you to inject a new firmare to the device without any proper authentication. For hacking, this opens a completely new avenue. If one could modify a firmware (and sign it), it would be possible to unlock locked devices, unlock features, or introduce new functionality.

Getting the box to the upgrade mode sounds easy:
turn power off from the device, keep WPS and Wi-Fi buttons pressed, kick on the power and at a suitable time release the Wi-Fi button. Then normal boot process is stopped and the box will wait for a firmware file to be delivered to it. In reality, it's bit tricky. Possible to do, but bit tricky.

Prerequisites

To get the upgrade rolling you'll need following things:

• Huawei E5186s-22a router
• A computer running Windows 7, 8 or 10
  • Administrator permissions for changing TCP/IP settings is required
• An ethernet cable to connect the computer to the router's LAN-port
• A firmware file to upload, filename will be something like BV7R2C0update_<version number>.gz.bin
• Multicast Upgrade Tool
  • This is not publicly available file
  • Tool's filename is multicast_upgrade_tool.exe, 3354624 bytes
  • The one I got was packaged into multicast.rar, 1040927 bytes.
  • SHA-256 sum of multicast_upgrade_tool.exe is 6224fe8fb0ec628a29ade1d7d5fb2db5183bfd43486037d0cdf8c363e8ed8eca
• WinRar packing utility from http://www.win-rar.com/ installed and working on your Windows

Setup

This is what my setup looks like:

I didn't have any switches or any other network appliance there, I just hooked the other end of the cable to my laptop and one end to the router. (The Kabuto car in the bottom corner is optional )

Next thing you'll need to confirm is your firewall software (or Windows built in one). Depending on what you have it may not allow the outgoing traffic.

The definition of upgrade traffic profile is as follows:

It is UDP, both initiator and responder are at port 13456. The obvious thing that you need to notice is, that traffic is multicast.

My firewall rule is:

Make sure you'll allow outgoing traffic to multicast address 224.0.0.119. For any layman, that looks like just another IP-address, but it isn't  one. It is in multicast address range and will be handled differently by TCP/IP-stack.

As all you TCP/IP savvy people know, multicast works no matter what your computer's IP-address is. That being said, I still recommend you change the computer's IP-address to network 192.168.8/24 which is used by the E5186. It is done from control panel (the screen shots are from Windows 10):

I didn't bother setting up any DNS-servers there. It will work without. The value of 192.168.8.100 is recommended by Huawei manual, so I used that.

Final setup thing is to make sure your Multicast Upgrade Tool can access WinRAR. On startup this will happen:

Just point the file selector to your already installed WinRAR:

That's it. That will do for the setup.

Update

Now this is the time to start practicing the upgrade mode -switch on power up.

First the normal, non-interrupt bootup sequence. It will look like this on your LEDs:

Serial console logs indicate, that you'll have 0,850 seconds from power-on to words "not in router upgrade mode" to be logged. So, I strongly suggest, that you'll keeps WPS and Wi-Fi buttons when you flip the power switch.

Your window-of-opportunity to release the Wi-Fi -button is between 0,850 and 1,890 seconds from power-on. If you release earlier, it's same as not pressing them at all. If you'll press them longer, you'll get the phrase "not in router upgrade mode" to the log, meaning that you failed.

This is what a success will look like:

If your blue LED keeps lit, like this:
Then everything is still ok. I cannot reproduce that every time, but I successfully updated firmwares with that status also. The idea is, that the blue LED keeps lit.

In that state the router is expecting you to start sending the file:

When you're successfully sending, the LEDs will indicate it:
The Wi-Fi LED will blink. It will go off once a while, but don't worry about it.

You can monitor the number of times, the file has been sent:

The entire upgrade can take like 10 minutes and you'll be transferring the file any number of times. Once I had to transfer it 11 times, before E5186 got all the bits of it.

Don't lose hope here!

Completing update

When your upgrade is completed and you're ready to power off the router, LEDs will look like this:
The Wi-Fi LED will go on and off slowly. It will keep doing that forever or until you power of the unit, whichever comes first.

Now you're done!

Go ahead kick the power back on and see how it went.

For the 2nd time, I got an E5186 loaner (post about the 1st time here). This time with permission to take a closer look inside.

Since this one had already RS-232 wires soldered, I took them for closer inspection. Un-boxing is exactly like in B593, 3 PH-2 screws holding the cover in place. Two at the bottom of the unit (one covered with a warranty paper) and one screw at the back between LTE-antennas.

Layout

After popping the cork, the board's flipside looks like this:

In this unit, there is no need to pry open none of the 4  shiny ESD covers. All the good stuff is on the other side. Again, 4 PH-2 screws holding the board in place.

Board, right side up:

In this case, the obvious clue for me was the already soldered RS-232 wires. I'm also publishing another picture by KOSH, a LTEforum.at activist, describing some of the good parts an E5186 board has:

There are 2 of: LTE/UMTS antennas on top corners, 5 GHz WLAN antennas at the sides and 2,4 GHz WLAN antennas on the bottom corners. The picture doesn't point out the locations of RS-232 pins, only the ground and Vcc pins.

Linux

A closer look of the Linux side pins right next to the SIM-slot:

No surprises there, the signal levels of RS-232 were 1,8 volts. It means, that an expensive USB-RS232 adapter is rquired for access. Your run-of-the-mill cheap 3,3 volt adapters are completely useless for this.

The descripions of RX/TX are from the point of the router (DCE), not from your computer (that would be DTE). It means, that any output signal (TX or transmit) described in the picture should be connected to input of the computer (RX or receive).

A bootup output of that port would be:

Digital core power voltage set to 0.9375V

[000002Fms]boot linux from flash

I don't think this side boots properly, so the output has only HiSilicon NAND-flash and Hynix DRAM mentioned.

Finally

I didn't manage to get any kind of console or prompt. There are couple of points where the Linux-side says "Press Enter to continue...", but event that didn't work. To me, it looks like the unit is not taking any input.

If you have any further information, please drop a comment below.

Just something out of one honeypot:

INbox mailer ==>> $7
Smtp Inbox Ip ==>> $ 10
Smtp inbox Domain ==>> $8
Smtp Unlimited ==>> $20
Shell ==>> $4
cPanel ==>> $5 
RDP administrator ==>> $15 
RDP user ==>> $6
SSH ROOTS ==>> $8
Emails Leads Individual 100,000 ==>> $25
Emails leads Co-operate 100,000 ==>> $50

If you're paying more than that, they're ripping you off.

Since the product descriptions are quite terse, I'm not sure what is an "INbox mailer", or what's the difference between "Smtp Inbox Ip" and "Smtp inbox Domain". A "Shell" or "cPanel" is self-descriptive, that's a simple access to *nix or a web-based hosting system. RDPs are for Windows remote access. But if you're buying 100k e-mail addresses, why are co-operate ones twice as expensive? That I don't know.

If you purchase those services, please let me know!

Year and half ago I wrote about my new super-fast Internet-connection. Since in this area the fiber-connections are installed to all buildings regardless you're going to use it or not, I had a possibility to start using also the second one. As the connection was already there, all my telco had to do was send the cable guy to install a fiber to copper media converter.

Or, so you'd think. The standard operating procedure seems to be to ship out needed hardware from the telco's central warehouse to me and eventually the cable guy would arrive and do the setup. The sales guy failed to mention this procedure to me. I received a shipment of my brand new toys:

I just unboxed all the stuff and started studying how to do the installation myself. My own experience on the subject is highly limited. Whenever fiber-optics are involved, all the installations are done by trained professionals, not curious hackers like me.

Anyway, this is the media converter a CTS (Connection Technology Systems, aka. Zyxel)  HET-3005:

According to manual, a HET-3005 comes in multiple versions. Mine is a model: HET-3005W2A(SM-10/20)-DR, it has following ports in it:

• Fiber Port
  • Speed: 1000
  • Type: WDM
  • Connector: SC
  • Distance: 10/20KM
  • Ports: 1
• TP Port
  • Speed: 10/100/1000
  • Ports: 4

In the fiber-world it seems, that connectors are always inside the box, of course I had to pop the hood:

On top of the pic, there is a fiber connector (a SC-connector, I guess):

It mentions following details:

• Dual rate
• Single mode, 10 km
• TX/RX: 1310/1550 nm

When studying Gigabit Ethernet, the only possible ones are:

• 1000BASE-LX10
  • Single-mode fiber using 1310 nm wavelength    10 km
• 1000BASE-BX10
  • Single-mode fiber, over single-strand fiber: 1490 nm downstream 1310 nm upstream    10 km

For obvious reasons of not having dual-rate in it, LX10 goes out. However in BX10, it's funny how specs mention downstream to be 1490 nm, but the equipment has 1550 nm.

So, only with the box, there isn't much to do. Luckily they kinda knew it and in the box there was a suitable patch cable:

The ends are different. I don't know why, but studying the Wikipedia article about Optical fiber connector says, that IEC 61754-4 defines a SC-connector. A careful analysis of it revealed, that the square one wasn't a match for the HET-3005. The wider one with non-square form fits in nicely:

Now I'll need to figure out what to do with the other end. I went to study the connections. A following box with obvious incoming fiber-optic cable rising from the ground was attached to a wall:

Sure thing, I popped the hood on that to see what it had eaten:

At the lower left hand corner, there is a black cable incoming. The cable guy stripped it and exposed the single-mode fibers in it (two of them) and welded them into the fiber of the blue connector. The welds have been properly covered with some sort of shink-wrap and can be seen in the yellow cable holder. Since the black box was a dead end, it had no electrical parts in it, my next focus was the blue connector at the bottom of the box:

That red connector had a fiber running to a box converting fiber to a DVB-C -signal and distributing that on a 75 Ω coaxial cable for TV-signal distribution into my house. However, the right connector was free. I simply had to try it:

Yep! A nice fit. The more important thing was, that it made my media converter box to indicate a functioning WAN-signal.

Just to confirm the SC-connector, I went back to pictures of my Inteno FG500, it had:

But that's inside the box, it has dual-purpose functionality of doing TV-signal and ethernet in two halves of the same unit.

After couple of days me finishing the install, the cable guy called in and wanted to come do the setup. I just told him that's its all done and ready.

Every now and then I need a paper copy of something. In Finland, which to my observations is quite far advanced in the paperless processes (working environment or otherwise), that's rare. The obvious exception to the rule is bookkeeping and banks. They won't live without a hard-copy of something. For the purpose of producing a printout I have a Samsung color laser printer. When it was new, I even made a humorous note of it.

The general grievance about modern printers is, that they cost around € 200,- and almost immediately run out of [insert a name of expensive supply product here]. In my case, nothing else than all colors cost way above € 300,-. But that's not my rant-of-the-day, I knew all about that when I decided to have the unit shipped to my front door. Korean engineers @ Samsung made the actual process of changing a color cartridge a very simple one. I have to say, that hardest part in that is un-boxing the new ones. They are so tightly vacuum-sealed. So, no groaning about that one either.

What do you do with those darned expired things, when you're done!!

I had replaced the black cartridge earlier, it always runs out first. In this instance, I replaced only the colour ones (CMY). So, only 3 useless boxes to throw out of the house.

From The Web, I found somebody having the same problem. This article is in Finnish, but it's pretty much about Samsung color cartridge not having any kind of recycling info in it. Samsun's rep reponnds, that "oh yes, there are instructions". This is the only thing I found about the subject:

It says to go to www.samsung.com/printer/recycle for information. I did and landed at Samsung S.T.A.R Programme (Samsung’s Takeback And Recycle). It has following information about returning used cartridges at How to return your used cartridge -page:

1. Place your used cartridge in the bag and box which came with your new Samsung toner cartridge. In case you wish to send more than one cartridge for recycling, please put all cartridges in one big box, or tape the individual boxes together.
2. Close the box using clear tape;
3. Register yourself/your company on our STAR website. In case you have already registered yourself/your company, please log in using your user name and password. Chose the number of empty cartridges you would like to return and press the ‘get your label!’ button. Your order will be processed immediately. Only one (1) return label will be sent to your registered email address or will pop up at your screen;
4. Print the return label and place it on the large side of the box. If the return label contains a bar code, please keep this bar code visible;
5. Drop off your box at the nearest post office or include it in your usual mail collection.

Well, I guess I'll have to register to the site and get myself some clear packing tape. After doing that, it was possible to print following packing slip:

Looks like a valid customer return information required by postal services. Now the last thing is to go to a post office and leave the bundle there.

So, the information was there. Obviously the entire process is a bit more complex than just taking out the garbage, but I guess Samsung guys will properly handle all the troublesome waste there. That should save the Earth!

As you may have noticed, I blog a lot about code, computers and operating system configurations. In writtern form, it is very convenient to use Teletype Text -formatting. Here is a demo of the difference:

Do Until NoMoreSwaps = True
     NoMoreSwaps = True
     For Counter = 1 To (NumberOfItems - 1)
          If List(Counter) > List(Counter + 1) Then
               NoMoreSwaps = False
               Temp = List(Counter)
               List(Counter) = List(Counter + 1)
               List(Counter + 1) = Temp
          End If
     Next
     NumberOfItems = NumberOfItems - 1
Loop

and:

Do Until NoMoreSwaps = True
     NoMoreSwaps = True
     For Counter = 1 To (NumberOfItems - 1)
          If List(Counter) > List(Counter + 1) Then
               NoMoreSwaps = False
               Temp = List(Counter)
               List(Counter) = List(Counter + 1)
               List(Counter + 1) = Temp
          End If
     Next
     NumberOfItems = NumberOfItems - 1
Loop

Any experienced software developer will prefer the fixed-width font. However, an out-of-the-box Serendipity blog software won't make that possible. I don't get the logic behind that, but there is a drastic change in functionality. To the not-so-user-friendly direction, I'd like to add.

Since version 2.0 S9y has been using CKEditor as HTML-editor on the admin-side. It is a pretty good component and has a number of excellent plugins already available. Getting a codeTag-plugin to work shouldn't be too hard, I guess. Yep! Guessed wrong.

Just downloading a zip-file, and uncompressing it at serendipity/htmlarea/ckeditor/ckeditor/plugins/-directory. Is a good start, but the editor won't react to that, something more is needed.

After a lot of investigating, I figured to add the name of the plugin into into serendipity/htmlarea/ckeditor_s9y_plugin.js. It has a line in it:

var customplugins = 'mediaembed,procurator,cheatsheet,';

adding codeTag into the list does absolutely nothing. It does load the plugin, but as a default, the plugin does nothing that you can see or touch. There is another file with list of editor's icons at serendipity/htmlarea/ckeditor_s9y_config.js. It has an array with list of icons to display:

config.toolbar_Default = []

It looks like this:

After adding this hash-definition into the config.toolbar_Default -array:

{ name: 'codetag',        items: [ 'Code' ] }

makes the icon to appear:

... but it doesn't do much when you click it.

Yet another round of debugging revealed, that there is a fixed list of allowed HTML-tags in the same file. The variable is called config.extraAllowedContent. The line is very long, but abbreviated version is something like this:

config.extraAllowedContent = 'mediainsert[*]{*}(*); ... ;pre[*](*);';

I added this to the end of the list:

code;tt;

Now it works as expected!

In my hugely popular article about Transferring Windows 7 OEM license to a new hard drive, I kept insisting, that you absolutely positively need to know your SLP-key before processing. Couple days ago I was working on a recovery of a failed hard drive and realized, that it's not completely true.

As the troubled drive had already been replaced with a brand new SSD, I had the HDD in an USB-dock for investigation purposes:

The new Windows 7 OEM had already been installed, but not activated. As I didn't know the SLP-key I was planning to do the phone activation with COA-key. At that point I realized, that it was possible to use the Magical Jelly Bean Keyfinder from another drive:

It wasn't much simpler than that! A simple copy/paste -operation to get the key in and Windows activated.

The requirement seems to be to point to a %windir% and system32\config\ is assumed on top of that.

Earlier I wrote about Storix and it's author Mr. Johnson.

The story developed further on 15th Dec when a jury gave its verdict about the copyright infrightment claim. A court decided that the copyrigt was transferred to company on 2003. Mr. Johnson claimed that a written memo of 2004 as an annual report didn't transfer the copyright:

It foolishly stated that my sole proprietorship was changed to an S Corp and "all assets" were
transferred over. Of course, I was referring to the cash in the business account, the furniture and
computers. But the jury, based on the courts generic instructions which were contrary to actual
copyright law, decided that it should include any personal assets related to the business,
or any "language that might encompass a copyright".

Obviously this is not the end of the story. There will be a round of appeals.

Btw. In their press release Storix claims to be "the #1 provider of disaster recovery solutions for more than 2,000 global customers". I think there has to be some other player in the disaster recovery business having more customers.

On version 43 Firefox announced: Firefox 64-bit for Windows Available.

Whoa! Already? I've been waiting for that to happen since 2005 when Fedora Core 4 was released. It had a 64-bit Firefox in it. Actually Fedora Core 3 had one, but it was a beta version and I didn't use it ever. So my 11 year wait is over.

Mozilla's release policy is ... how to put it ... confusing? Insane? Mindless? Linux and OS X had proper versions of my favorite browser years ago, but on Windows, they seriously dopped the ball. Competition have had 64-bit builds for: Internet Explorer, Opera, Chrome, Dillo and what not. Even the mostly malfunctioning slow piece of crap Edge has a 64-bit build of it.

Back in 2011 there was a decent version of 64-bit Firefox 8 in the works. See article Firefox 8 for Windows x64: Has 64-bit browsing finally come of age? about that. Then came 2012 and at end of that year something happened: Mozilla quietly kills Firefox 64-bit for Windows, despite an estimated 50% of testers using it. 

Here is the 2012 Mozilla’s manager list of bullshit reasons for not doing a 64-bit version:

• Many plugins are not available in 64-bit versions.
• The plugins that are available don’t work correctly in Firefox because we haven’t implemented things like windowproc hooking, which means that hangs are more common.
• Crashes submitted by 64-bit users are currently not high priority because we are working on other things.
• This is frustrating for users because they feel (and are!) second-class.
• It is also frustrating for stability team triage because crash-stats does not easily distinguish between 32-bit and 64-bit builds in the topcrash lists and other reports. We basically ignore a set of nightly “topcrashes” because they are 64-bit only. (See bug 811051).

I'd still like to point out that at that time Linux and OS X had it. The list is total bullshit, as the crash reports and triage would have easily identified build bitness with minor changes, if only there would have been a true will of doing it. Most of people like me didn't care about lacking plugin support. Everything that I needed was already there and working.

Since there were a lot of comments about not doing the 64-bit Windows version, there was some flip-flopping about the decision: Mozilla backpedals on Firefox 64-bit for Windows, will keep nightly builds coming after all.

There were couple of silent years, then the project had a come-back. On 2014: Mozilla is making plans for 64-bit Firefox browser. As the decision was in to go for 64-bit, the only thing missing was developer resources. Obviously Mozilla was busy developing features, not the 64-bit build. Hower, last summer there was news: Mozilla delays 64-bit Firefox for Windows again. And finally, couple of releases later they had the official stable version out.

The obvious effect will be for Cyberfox. 8pecxstudios has been very active in the 64-bit scene and I've been using their excellent product for couple of years. My previous favorite, Waterfox advertises being a high performance browser based on the Mozilla platform made specifically for 64-Bit systems. They say that Waterfox has one thing in mind: speed, however, it's in a very low maintenance mode and currently it is 3 versions behind. In my book, that's unmaintained already.

I strongly doubt that none of the excuse-list items have vaporized. I'm glad that the version is out, but not very happy that it took so many years. This entire case is a disgrace.

Software developers are stupid morons!

I have worked as one for couple of decades, so take my word for it. I know quite a few of them. Stupid morons, software developers and people who are both.

The reason for my rant is this JavaScript bugger:

var t = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;

It keeps popping up constantly. For people not familiar with regular expressions, that is a piece of code to match a valid e-mail address as specified by the one and only, original specification for ARPA Internet Text Messages, which we call e-mail today. As I keep insisting, software developers have major deficit both on writing proper code and testing their writtern code. For non-software developers: the reason that ill written line of code has spread around the internet like autumn flu, is that people just google for the regexp and copy/paste it into their product without thinking it for a second. It worked last time, right?

Here are the facts:
This is the list of IANA approved top-level-domains: http://data.iana.org/TLD/tlds-alpha-by-domain.txt in plain-text format. The list contains 1115 domains at the time of this vent. 570 of them are longer than 4 chars as limited by the above piece of crap. That results only 49% of valid TLDs being approved as valid ones. Anybody doing his/hers work only by 49% of success should be fired! Instantly.

Examples of valid TLDs:
As an example, the IANA list contains following domains: .cancerresearch, .xn--t60b56a, .international and .xn--vermgensberatung-pwb. The ones having lettersn XN, are internationalized domain names or IDNs. When decoded, .xn--c2br7g equals to नेट, .xn--t60b56a equals to 닷넷, both meaning .net in Hindi and Korean. Another ones are .xn--mgba3a3ejt for ارامكو, Saudi Aramco, the Saudi Arabian Oil Company and .xn--vermgensberatung-pwb for .vermögensberatung, German for financial advice. All of them are fully valid, but not being validated by the ancient piece of copy/paste mess everybody seems to be using.

Some of the weaker players:
The idiot-of-the-year -award doesn't go to http://www.moonfruit.com/ or http://tunnus.yle.fi/ who are strong competitors using that relic of a validator. The obvious winner is https://www.startssl.com/, who have a hard-coded list of 2827 domains and subdomains, having only 464 of the TLDs in the IANA-list. 651 of them missing, matching only 42% of the valid ones. Idiots!

If you are a software developer and reading this: It's time to shape up! Stop doing your job poorly.
