Work around G+ “403. That’s an error.” errors

Posted by jpluimers on 2016/07/08

I’m not yet sure what the exact cause is, but at irregular intervals when clicking on Google Plus links, they show as “403. That’s an error.”.

They appear both when I have multiple WAN connections or a single WAN connection, which leads me to suspect that G+ doesn’t cope well when

  • you have a lot (dozens) of Google related pages open (Drive, Mail, Search, Documents, etc) as Google Plus is embedded in each of them
  • you rapidly browse through your G+ backlog (the G+ counter is > 50 since you follow a lot of people/communities and you quickly do catch-up on them)

In a future post, I will explain how I created the workaround, but here it is:

Work around G+ “403. That’s an error.” errors

Basically it translates links

The latter was the original link I clicked in the first place. The former what G+ comes up with.

After a while, G+ comes back to its senses and allows the latter links again, so the page allows you to parse the former then put them in a list like this:

One decoded URL per list-item.

One decoded URL per list-item.

HOWTO: Multirouting with Linux : Luke Cyca Dot Calm

Posted by jpluimers on 2016/07/08

Multihoming without BGP with home routers and Linux. Need to apply this on OpenSuSE one day: HOWTO: Multirouting with Linux : Luke Cyca Dot Calm.

Basically it does Multirouting of Sessions using NAT, routing tables, rules, removal of the default routing and adding a round robin routing, fixing DNS, adding more rules and creating a failover script.

In case it ever goes offline: the WayBack Machine link.

Some more background research links:

James Newman built himself a 16-bit Megaprocessor using transistors in frames taking 12 by 2 meters. Wow!

Posted by jpluimers on 2016/07/07

It took James Newman more than one and a half years of actually building progress and more than that (thinking about it started in 2011) for designing his own Megaprocessor using transistors.

For like EUR 50000 and a lot of “learning opportunities” he built himself a room full of visual computing: you can see the LEDs on all the PCB boards indicating exactly what’s going on (heck: he even made the RAM visualise an actual tetris implementation).

All for the sake of understanding transistors and discrete logic after which things got out of hand.

Hopefully a tech museum will buy this.

His site as a truckload of information, for instance the Source: Megaprocessor – FAQ: good/bad/ugly linking to lots of technical details and decisions made (like throwing out surface mount components but using lead based solder or having dual output logic).

There’s a lot of video too (like Megaprocessor – How ?) but – especially these weeks – the downloading is slow, to it’s faster and easier to watch his Youtube playlists:

They are currently 6 videos each, but he has uploaded more videos and is working on more.

Finally, James even built an assembler for this 16-bit processor. How cool is that!

Resource decompiler – converting/decompiling/extracting .RES files into .RC files and separate resources

Posted by jpluimers on 2016/07/07

via: Resource decompiler

One day I’m going to need ResourceHacker as it has an -extract option to extract resources.

The above link even has a batch file that can server as a start automating that process:

@echo off
set file="GeneSys"

if exist %file%.rc del %file%.rc

ResHacker.exe -extract %file%.res, %file%.rc,  Bitmap,,
ResHacker.exe -extract %file%.res, temp.rc,  Icon,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Dialog,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Menu,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  StringTable,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Accelerators,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  VersionInfo,,
type temp.rc >>%file%.rc
del temp.rc

I save it as extract.bat and a commandline usage: extract GeneSys will extract all the resources from GeneSys.res

–jeroen

PS: as the MASM forum sometimes nags with logins, I saved the above page in the wayback machine.

I’ve verified that [WayBack] ResourceHacker and the downloads ([WayBack] installer and [WayBack] portable) are there too.

Vysor Pro Feature – Go Wireless to mirror and control your device without a USB Cable…

Posted by jpluimers on 2016/07/06

If you have a [Wayback/Archive] Vysor Pro (either subscription or one-time payment for life-long usage), then you can use this new [Wayback/Archive] New Vysor Feature – Go Wireless Click that button to mirror and control your without a USB cable…

There are more Pro features to come; currently they are:

  • High Quality Mirroring
  • Fullscreen Mode
  • Go Wireless
  • Vysor Share
  • Drag and Drop Files
  • Access to all future features

If Google Pay doesn’t work in your country, then you can use PayPal. When that doesn’t work either, well…

Another nice Vysor Pro feature: [Wayback/Archive] Vysor Share Server – an easy Android device farm: You can share all your Android devices at once using the new Share All feature. – Koushik Dutta (Koush) – Google+

case insensitive files systems and git – Lesson Learned – I Can’t Get My Git Repo Clean! | DrupalEasy

Posted by jpluimers on 2016/07/06

via: Lesson Learned – I Can’t Get My Git Repo Clean! | DrupalEasy

One file kept getting added to the git modified list: service/src/main/MySOAPdefinition.pas.

It was part of a repository that had been migrated from SVN (more on that in a future blog post) and along the way been renamed in directory service/src/main from MySOAPdefinition.pas to MySoapDefinition.pas. SVN (and TortoiseSVN) don’t object to this. But git does.

You’d see this on the command-line:

>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   service/src/main/MySOAPdefinition.pas

no changes added to commit (use "git add" and/or "git commit -a")

>git add service\src\main\MySoapDefinition.pas

>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   service/src/main/MySOAPdefinition.pas

no changes added to commit (use "git add" and/or "git commit -a")

Basically the add would do nothing.

On Windows, this is how to get around this:

Latency Numbers every Programmer and Architect should know

Posted by jpluimers on 2016/07/06

Via +Martin Blais, Philippe Beaudoin, Lars Fosdal as Useful resource……:

Hit the cache, Jack…

Interactive Chart of Latency Numbers every Programmer Should Know (from 1990s until 2020s including script to draw the cart).

Also, this variant by Erik Meijer from Coursera (https://www.coursera.org/course/reactive): https://d396qusza40orc.cloudfront.net/reactive/lecture_slides/Latency%20as%20an%20Effect%201.pdf#page=10

Via Asbjørn Heid:

Following up on +Lars Fosdal’s earlier post here’s a talk by Herb Stutter which goes into more detail of where the performance is these days.

It’s a general talk, not C++ specific. Recommend it to get some idea of what goes on under the hood these days,  and so one doesn’t try to do some premature optimization which may turn out to be bad.
