ADSL2+ on Long Line

Recently received an email from BT saying that they will be upgrading the line this week. The SWCNE exchange was upgraded to ADSL2+ around the 31st March. Some people in the village received this email a month ago and was upgraded then, however not sure if there will be any benefits.
Also we were getting a broadband download speed of around 0.2 - 0.8mbps around a month ago till BT found a problem on our line. After many line profile resets and a new HH3 we are now achieving a download speed of around 0.7-1.1 mbps. This was done about 3 weeks ago, the cause of the problem was due to problems with the BT Retail servers, work on the exchange and due to the line.

currenly plugged into the BT Openreach ADSL v.1 main telephone socket.
After the exchange upgrade will I benefit from ADSL2+?

I'm no expert, so please correct me if I'm wrong

The SWCNE Exchange was upgrading everyone who had not been moved to the adsl2/2+ service today.
After the upgrade the HH3 reconected to the internet but on the same G.992.1 Annex A line modulation. The noise margin has also gone up from 4.5 db to 8.9 db which has resulted in the sync speed to be reduced. However the line attenuation has decreased from 68.2 to 66.6
Here are the Home Hub stats.
Download speeds
I was achieving a download speed of around 1.1mb with an IP profile of 1.25mb
And now achieving a download speed of around 0.96mb with an IP profile of 1.12mb
Is there anyway of improving it as the upgrade haven't managed to improve it?

ADSL or ADSL2 on a long line?

i have BT business boadband (office unlimited ADSL2 Next Gen (up to 20 Mb)). Historically i have had poor broadband hence swapping to business to try and improve matters. i have now ditched the home hub and gone to a 7800N which has made a big difference. although over Christmas the flashing lights played havoc with the broadband and now i have a high SNR margin and interleaving..
However, my main question is will it be worth me pushing for ADSL2 given my line (stats from DSL stats below). currently my router will only connect with G.DMT so i am assuming i can only get ADSL? Will ADSL2 or indeed 2+ improve speed/stability on a long line with attenuation around 62 dB?
thanks everyone

How to handle long lines in a JAD file?

Hi all,
setting MIDlet permissions in a JAD file easily expands the length of one line so that they need to get wrapped into 2 or more lines. AFAIK JADs actually are manifest files and the manifest file spec says that a line continuation is marked by a line beginning with a single space. I use Ant to create the JAD file and Ant's manifest task does it exactly like this. Example:
MIDlet-Permissions: javax.microedition.io.Connector.bluetooth.client,j
avax.microedition.io.Connector.socketThis works on my Sony Ericsson phone and in the MicroEmu emulator, but the WTK (2.5.2) emulator complains about that by throwing an exception:
com.sun.midp.midletsuite.InvalidJadException: Reason = 28
     at com.sun.midp.midletsuite.JadProperties.partialLoad(+259)
     at com.sun.midp.midletsuite.JadProperties.load(+8)
     at com.sun.midp.dev.DevMIDletSuiteImpl.create(+252)
     at com.sun.midp.dev.DevMIDletSuiteImpl.create(+74)
     at com.sun.midp.main.Main.runLocalClass(+20)
     at com.sun.midp.main.Main.main(+80)So who is wrong here?
Thanks for some information!
Best regards,
Brian

MIDlet-Permissions: javax.microedition.io.Connector.bluetooth.client,j
avax.microedition.io.Connector.socketif memory serves, inability to handle stuff like above is a known WTK bug.
Try workarounds like "glueing" permissions into single (long) line or splitting them on commas

How can I change the view in Show Page Source from one long line to a more readable view

When using Develop --> Show Page Source in Safari 6.0.1 I get a view of the html that is just one long line. I can scroll along to the right but it is not very easy to use.
It seems to me that when I first used this feature I had a formatted view, that is the text was broken into separate lines and was easier to read.
But I think I clicked on something and it change to one line. I can't find a way to change it back.
Is anyone familiar with this? Or can point me to more information about Show Page Source formatting?
Thanks.

Oh, I see the problem.
The one long line view only occurs when I'm viewing a page locally on my own computer. (When I choose Show Page Source for any page on the internet the display is formatted normally.)
So obviously if I want to see the code in my own files I can just go open them in the text editor. I used to use View Page Source (previous version of Safari) as a shortcut for a quick peek. If there is a solution to this formatting thing for local files I'd love to know it, otherwise I'll just put it on the you-can't-do-that-anymore list.

How to print a text file with long lines?

I am trying to print a text file which contains many long lines. I find that the long lines are truncated on the printouts. How do I wrap up these long lines? Could you give me some examples?

When using the "Fill & Sign PDF" feature, is there a way to stretch to size the text box, for a specific area on the page...instead of it going on in one straight long line...?

When using the "Fill & Sign PDF" feature, is there a way to stretch to size the text box on a specific area of the page...instead of the text box going on in one straight long line....? I'm not seeing there's an option or ability to do so, just wanting to confirm.

Improving the handling of multiple line text fields is in our plans, but for now, you will have to add manual carriage returns (Enter).
Thanks,

Where is the long line "--" on the key board?

where is the long line "--" on the key board? I can only find a short one and thus have to press is twice.

Here's a somewhat more helpful answer:
option-shift-hyphen
This will give you what's called an em-dash. If you also want an en-dash (commonly used to separate groups of numerals, as in phone numbers in printed materials):
option-hyphen
Here's more about typing special characters and symbols:

Long lines corupt script output

When SQL run as Script (F5) produces too long lines any Script Output gets blank. Text is there in tab Script Output and I can copy and past it but I can't see it.
What setting could affect this?
--This SQL is working fine
select rpad('Test1',4000), rpad(' ',996) from dual;
--and this sql output is white on white:
select rpad('Test2',4000), rpad(' ',997) from dual;

I have successfully exported subtitles (XML files) from FC version 7 to FC version 6, by choosing Apple XML Interchange Format Version 4. Now the exported subtitles suddenly read in one long line, at the top, not registering any "Enter" keystrokes.

I have successfully exported subtitles (XML files) from FC version 7 to FC version 6, by choosing Apple XML Interchange Format Version 4. Now the exported subtitles suddenly read in one long line, at the top, not registering any "Enter" keystrokes. The same happens even if I re-import the XML file into Final Cut Version 7 (from where I exported the subtitles). Any tips on how to fix this?

You might see if you can bring the xml file into Title Exchange Pro
http://www.spherico.com/filmtools/TitleExchange/
It's a great program and the author was very responsive when I had a problem.
If it reads correctly, you can probably save it back out.
If you want to send it to me, I'll see if it opens.

How to break down long lines of code

Is there a way to break a long line of code so that it will fit on an A4 sheet?

You can break on most dots between variable name and method name, between spaces in operators, after a comma that separates parameter names, etc. Just about the only thing you can't break is a long literal String--though you could type it on multiple lines by breaking it into pieces and putting a + in between the pieces.

How can long lines of code be cut / separated into multiple short

In Java, How can long lines of code be cut / separated into multiple short lines?
Example
System.out.printf( "%d\t%d\t%s\t%s\t%s\t%s\t\t%s\n", arrayIndex , part[ arrayIndex ], name[arrayIndex], units[arrayIndex], price[arrayIndex], units[arrayIndex] * price[arrayIndex], total[ arrayIndex ] );Thanks

System.out.printf( "%d\t%d\t%s\t%s\t%s\t%s\t\t%s\n",
arrayIndex ,
part[ arrayIndex ],
name[arrayIndex],
units[arrayIndex],
price[arrayIndex],
units[arrayIndex] * price[arrayIndex],
total[ arrayIndex ] );P.S. It looks to me like you have an array for each attribute of something. This is not OO and you should consider creating a class holding the information about each 'Part' or whatever it is. You will then just need a collection of Parts.

Sending/receiving email with long lines of text.

Using mail with yahoo plus. Composed emails have long lines of text. Recipients complain that they have to scroll left to right to view them. Not so on a PC with Outlook, anyone know of a solution to this. Thanks

Hi Chris,
Thanks for the response. No, there were no rules set, but your query gave me ideas. I'd never been in the rules section before, but I played with it for a while with some trial and error and finally made a rule that set all the emails to show with black text, and duplicated it for all the mailboxes, and voila! there were all the emails listed in black text.
While I'm sure there are more effective ways of writing a rule, my rule worked fine. I had it say that if "any" of the following conditions are met: "From" "Contains" "@", perform the following actions: "Set color" "of text" "Other [black]" and applied it to the mailbox.
Thanks for the spark of the idea.

OS X Mail long lines of text don't re-flow

Using Mail in OS 10.4.11 when I receive emails from some clients they include disclaimers etc. which do not re-flow to the width of the email window. Consequently when I print the email the whole of the long line is fitted across the page making the text of the message too small to read. Even changing the page orientation doesn't make the text readable. Anyone have any suggestions?

To add more; I first noticed this 2 days ago and reported it to Apple. When I did notice it, I went to preferences and changed how many lines of the content preview shows, then I closed the message view column and expanded the preview column as wide as I could get it. On one of the messages, it kept continuing after it ran out of space in the preview, for a running total of at least 100 words. Even then, in the actual message viewer, it only showed 1 complete message of about 25 words.

Post 21CN WBC Experiences - Long Line?

Hi
My rural exchange is due for 21CN WBC upgrade this June
I was wondering if anyone has had a good experience following this type of upgrade - specifically on a long line
The 'experts' claim there will be no positive impact for low speed long line sufferers but interested to hear from anyone with 'real life' experience of this
My stats:
Sync around 1.3meg
D/Load around 900k
U/Load around 280k
snr down 6db
Line Att 74db
Router/modem BT 2Wire 2700
Faceplate fitted

big difference from 55 to 74 though a 1.3mb connection with 74 attenuation is good

How to increase your speed on long lines

After 4 engineer visits and everyone saying that at 1300m from the cabinet 12mb was going to be the best speed I could get I have found a way to nearly double my speed. Dumped the homehub5 and replaced it with a Billion 8800NL and now have a steady 21.5mb and not one dropped connection.
So if you are on a longer line its worth a try for £68 from Amazon.
Thought I would share this as I found it so frustrating that I could get nowhere near the speed I was sold now im just 1mb away from the lower estimate so I can live with that.

That's an amazing speed for your attenuation
