Open Source: Kompozer HTML Editor

I did an initial install and run of Kompozer HTML editor.

It seems pretty good. I have tried Amaya in the past but can not seem to get the hang of all the gobble de gook they toss in. It is like they never heard of WSIWYG and why it works so much better.

Lintz’s Notes about Android Rooting and Unlocking

General point, all phones: As I unlocked various phones over the years, i found xda-developers forums to be the best for knowledge and tools:

http://forum.xda-developers.com

I did not use them immediately time,which cost me some time. should have used the geeky way below

(samsung galaxy s vibrant (sgh-t959) xda-dev geeky way)

Quick Explanation:

xda page with unlock tools:

http://forum.xda-developers.com/wiki/Samsung_Galaxy_S/SGH-T959#Unlocking_your_phone

Samsung Galaxy S Vibrant sgh-t959 no brain, tools way, which i used. I now remember what messed me up was getting the kies usb drivers to work (i am on win7). threw away notes but my memory is:

installed Kies MINI (for usb drivers). regular kies messed me up
temp rooted the phone using z4root (sideloaded)
http://forum.xda-developers.com/showthread.php?t=833953
loaded busybox from google play, and sideloaded Galaxy S Unlock:
http://forum.xda-developers.com/showthread.php?t=906255

– Was amazed it actually worked!

Good luck, xda-dev is your friend …

Software

Software: ChromeCacheView – easily view chrome cache content

Viewing the chrome cache files can be a pain by the manual cut and paste method. The files are full of binary representations that make no immediate sense to a human. You have to copy all and paste into an online tool. Be careful to not refresh pages of interest when recovering files. It will wipe out the files if you do. Better yet there may be a setting that you can turn off to prevent any erasure while you are doing your recovery.

View the cached objects using: How to retrieve temporary internet files
Paste the file into this page: Viewing chrome cache

There is a much better solution:

Download and install ChromeCacheView

ChromeCacheView runs as an application on your machine and you can view whole webpages and images by just using the appropriate menu function. MUCH BETTER.

Satoshi Nakamoto’s paper on Bitcoin

The math nerds strike back. And are co-opted.

DSL

DSL Phone Line Extension

Research Notes

Wikipedia: ADSL loop extender
Ebay: POTS over Fiber – if you really want to go far
Wikipedia: Digital Subscriber Line ( DSL )
Google Books: Propagation loss of 1000 feet of addition twisted pair quoted at 6db

Given the graph below I surmise that the extra 500 feet to Loo's house will not affect the speed much.

Conclusions

We can probably just use twisted pair inside network cable to extend DSL up to Loo's.
A back up plan would be to place the DSL modem at Claudio's and run the ethernet over fiber solution up to Loo's.

Extending Ethernet Long Distances using Fiber Optic Media Converters

Research Links

MC111CS – The data sheets are available under the download tab. Purchased.
MC112CS – Purchased
Ebay: 120 Ft Test cable Purchased: with correct connectors – in reality I need 250 Meters but this is cheaper to make sure all else is working before I buy the much more expensive fiber optic cable.
Ebay: 250 Meter SC SC Fiber Optic Cable – will need to take at least one spare. See the table at the bottom.
Ebay: 300 Meter SC SC Fiber Optic Cable – Outdoor – appears outdoor means a black heavy jacket has been added to same type of cable as entry immediately before this one.

The MC111CS and MC112CS are complimentary in that the Tx wavelength is the Rx wavelength of the other. See excerpt below.

The MC112CS is a media converter designed to convert 100BASE-FX fiber to 100Base-TX copper media or vice versa. Adopting WDM technology, MC112CS takes only one fiber cable to transmit and receive data, which will save half cabling cost for you. Designed under IEEE 802.3u 10/100Base-TX and 100Base-FX standards, the MC112CS is designed for use with single-mode fiber cable utilizing the SC-Type connector. The MC112CS supports longwave (LX) laser specification at a full wire speed forwarding rate. It works at 1310nm on transferring data and at 1550nm on receiving data. So the other end device to cooperate with the MC112CS should work at 1550nm on transferring data and at 1310nm on receiving data. Another TP-LINK?s media converter MC111CS is just one of the examples to cooperate with MC112CS.
