Green interior design inspiration
Awkwardness gives me great comfort. I’ve never been cool, but I’ve felt cool. I’ve been in the cool place, but I wasn’t really cool – I was trying to pass for hip or cool. Fashion never stops. There is always the new project, the new opportunity.
Awkwardness gives me great comfort. I’ve never been cool, but I’ve felt cool. I’ve been in the cool place, but I wasn’t really cool – I was trying to pass for hip or cool. Fashion never stops. There is always the new project, the new opportunity. I always say: To be well dressed you must be well naked.
A girl should be two things: classy and fabulous. I am convinced that there can be luxury in simplicity. I wanted to dress the woman who lives and works, not the woman in a painting. It’s hard to balance everything. It’s always challenging. My relationships with producers or photographers – these are relationships that took years. I can’t get sucked into that celebrity thing, because I think it’s just crass. My aim is to make the poor look rich and the rich look poor. Vanity is the healthiest thing in life. I believe that my clothes can give people a better image of themselves – that it can increase their feelings of confidence and happiness. You can hide so much behind theatrics, and I don’t need to do that any more. I don’t really know how to do casual clothes.
Breaking Up With Fast Fashion Has Been Easier
Awkwardness gives me great comfort. I’ve never been cool, but I’ve felt cool. I’ve been in the cool place, but I wasn’t really cool – I was trying to pass for hip or cool. Fashion never stops.

Awkwardness gives me great comfort. I’ve never been cool, but I’ve felt cool. I’ve been in the cool place, but I wasn’t really cool – I was trying to pass for hip or cool. It’s the awkwardness that’s nice. We look our best in subdued colors, sophisticated cuts, and a general air of sleek understatement. I like the body. I like to design everything to do with the body.
“I try as much as possible to give you a great basic product and what comes out, I feel, is really amazing.”
If I fell in love with a woman for an artistic reason, or from the point of view of my work, I think it would rob her of something. We live in an era of globalization and the era of the woman. Never in the history of the world have women been more in control of their destiny.

It has been argued that to prevent shootings (and for many other reasons), schools should invest in supporting students’ mental and physical well-being. However, in most states, there is a shortage of nurses, social workers, psychologists, and counselors in schools. In this section, you will compare numbers of school support staff (including SROs) in different states.

IWPRIV
Section: Linux Programmer's Manual (8)Updated: 31 October 1996
Index Return to Main Contents
NAME
iwpriv - configure optionals (private) parameters of a wireless network interfaceSYNOPSIS
iwpriv [interface]iwpriv interface private-command [private-parameters]
iwpriv interface private-command [I] [private-parameters]
iwpriv interface --all
DESCRIPTION
Iwpriv is the companion tool to iwconfig(8). Iwpriv deals with parameters and setting specific to each driver (as opposed to iwconfig which deals with generic ones).Without any argument, iwpriv list the available private commands available on each interface, and the parameters that they require. Using this information, the user may apply those interface specific commands on the specified interface.
In theory, the documentation of each device driver should indicate how to use those interface specific commands and their effect.
PARAMETERS
- private-command [private-parameters]
-
Execute the specified
private-command
on the interface.
The command may optionally take or require arguments, and may display information. Therefore, the command line parameters may or may not be needed and should match the command expectations. The list of commands that iwpriv displays (when called without argument) should give you some hints about those parameters.
However you should refer to the device driver documentation for information on how to properly use the command and the effect. - private-command [I] [private-parameters]
- Idem, except that I (an integer) is passed to the command as a Token Index. Only some command will use the Token Index (most will ignore it), and the driver documentation should tell you when it's needed.
- -a/--all
- Execute and display all the private commands that don't take any arguments (i.e. read only).
DISPLAY
For each device which support private commands, iwpriv will display the list of private commands available.This include the name of the private command, the number or arguments that may be set and their type, and the number or arguments that may be display and their type.
For example, you may have the following display :
eth0 Available private ioctl :
setqualthr (89F0) : set 1 byte & get 0
gethisto (89F7) : set 0 & get 16 int
This indicate that you may set the quality threshold and display an
histogram of up to 16 values with the following commands :
iwpriv eth0 setqualthr 20
iwpriv eth0 gethisto

Projects are meant to help out with repetitive tasks. A Project contains:
Location of files to compress.
Location of files to manage script-includes.
Compression and obfuscation settings.
Projects are stored in the [program dir]\projects folder in an XML format. You can either manually edit them, or create and edit them through the JSCruncher UI, on the Home page.
Projects can be run by first loading them from the Home page, and then selecting 'run'. Projects can also be run from the command line tool, making them ideal for use in build scripts.


perl5144delta - what is new for perl v5.14.4
This document describes differences between the 5.14.3 release and the 5.14.4
release.
If you are upgrading from an earlier release such as 5.12.0, first
read perl5140delta, which describes differences between 5.12.0 and
5.14.0.
This release contains one major, and medium, and a number of minor security
fixes. The latter are included mainly to allow the test suite to pass cleanly
with the clang compiler's address sanitizer facility.
With a carefully crafted set of hash keys (for example arguments on a URL), it
is possible to cause a hash to consume a large amount of memory and CPU, and
thus possibly to achieve a Denial-of-Service.
This problem has been fixed.
The UTF-8 encoding implementation in Encode.xs had a memory leak which has been
fixed.
A read buffer overflow could occur when copying
"sockaddr" buffers. Fairly harmless.
This problem has been fixed.
An extra byte was being copied for some string literals. Fairly harmless.
This problem has been fixed.
A string literal was being used that included two bytes beyond the end of the
string. Fairly harmless.
This problem has been fixed.
Under debugging builds, while marking optimised-out regex nodes as type
"OPTIMIZED", it could treat blocks of exact
text as if they were nodes, and thus SEGV. Fairly harmless.
This problem has been fixed.
The statement "local $[;", when preceded by an
"eval", and when not part of an assignment,
could crash. Fairly harmless.
This problem has been fixed.
Reading or writing strings greater than 2**31 bytes in size could segfault due
to integer wraparound.
This problem has been fixed.
There are no changes intentionally incompatible with 5.14.0. If any exist, they
are bugs and reports are welcome.
There have been no deprecations since 5.14.0.
The following modules have just the minor code fixes as listed above in
"Security" (version numbers have not changed):
- Socket
- SDBM_File
- List::Util
Encode has been upgraded from version 2.42_01 to version
2.42_02.
Module::CoreList has been updated to version 2.49_06 to add data
for this release.
No new or changed diagnostics.
- VMS
- 5.14.3 failed to compile on VMS due to incomplete application of a patch
series that allowed "userelocatableinc"
and "usesitecustomize" to be used
simultaneously. Other platforms were not affected and the problem has now
been corrected.
- •
- In Perl 5.14.0, "$tainted ~~ @array"
stopped working properly. Sometimes it would erroneously fail (when
$tainted contained a string that occurs in the
array after the first element) or erroneously succeed (when
"undef" occurred after the first
element) [perl #93590].
Perl 5.14.4 represents approximately 5 months of development since Perl 5.14.3
and contains approximately 1,700 lines of changes across 49 files from 12
authors.
Perl continues to flourish into its third decade thanks to a
vibrant community of users and developers. The following people are known to
have contributed the improvements that became Perl 5.14.4:
Andy Dougherty, Chris 'BinGOs' Williams, Christian Hansen, Craig
A. Berry, Dave Rolsky, David Mitchell, Dominic Hargreaves, Father
Chrysostomos, Florian Ragwitz, Reini Urban, Ricardo Signes, Yves Orton.
The list above is almost certainly incomplete as it is
automatically generated from version control history. In particular, it does
not include the names of the (very much appreciated) contributors who
reported issues to the Perl bug tracker.
For a more complete list of all of Perl's historical contributors,
please see the AUTHORS file in the Perl source distribution.
If you find what you think is a bug, you might check the articles recently
posted to the comp.lang.perl.misc newsgroup and the perl bug database at
http://rt.perl.org/perlbug/ . There may also be information at
http://www.perl.org/ , the Perl Home Page.
If you believe you have an unreported bug, please run the perlbug
program included with your release. Be sure to trim your bug down to a tiny
but sufficient test case. Your bug report, along with the output of
"perl -V", will be sent off to
<EMAIL_ADDRESS>to be analysed by the Perl porting team.
If the bug you are reporting has security implications, which make
it inappropriate to send to a publicly archived mailing list, then please
send it to<EMAIL_ADDRESS>This points to a closed
subscription unarchived mailing list, which includes all the core
committers, who be able to help assess the impact of issues, figure out a
resolution, and help co-ordinate the release of patches to mitigate or fix
the problem across all platforms on which Perl is supported. Please only use
this address for security issues in the Perl core, not for modules
independently distributed on CPAN.

We employed image recognition of food ingredients, specifically vegetables, to recommend recipes based on the recognized ingredients.
Timeline:
1 month

Responsibilities: Research, dataset creation and testing different machine learning models on those datasets
Tools:
Microsoft Azure
Jupiter Notebook for python
Flask framework for front end development
ImageNet for Dataset creation
There are several cooking apps or websites available today, that are used to find recipes based on some keyword, like name of the food ingredient or type of cuisine, etc. These apps are mindful of the needs and interests of their users, but they fail at identifying their user's constraints, i.e., limited number of food ingredients. In such cases, users find themselves shopping for ingredients or they decide to substitute the missing ingredient with something else. To help users avoid such adjustments, image recognition can be employed to identify food ingredients that are already available at their disposal and recommend them recipes based on those ingredients.
Currently the system is a web application that performs image recognition on the uploaded images and recommends recipes that contains the recognized ingredients. We built a convolutional neural network model for image recognition to identify five categories of food ingredients and achieved, 62.9% accuracy rate. The recommendation system uses the labels of the identified images to display a list of recipes that contains most of the identified ingredients.

Please follow this link to view the concept video
Through this project, I learnt to build different machine learning models to improve upon the accuracy for object recognition. How we build the dataset affects the model greatly and hence it is extremely important to clean the data before using it. We also found that as we increased the number of categories of the food ingredients, the accuracy dropped significantly. Hence, as we realized that in order to increase the number of categories, it is important to increase the number of images for all other categories to achieve best possible result.

WELCOME TO COBALT INDUSTRIES! THE INDUSTRY LEADER IN NUCLEAR POWER AND PROPULSION, SATELLITE IMAGING AND TELECOMMUNICATION, AND BIOMIMETIC ORGANOSYNTHESIS. BRINGING AMERICA INTO A BRIGHTER TOMORROW, TODAY!
 WHILE ADAPTING TO LIFE ON THE ISLAND CAN BE DIFFICULT, REST ASSURED THAT ALL OF US AT COBALT HQ (AS WELL AS OUR FRIENDS AT THE AGENCY) ARE EVER GRATEFUL OF THE IMPORTANT WORK YOU WILL DO HERE.
PLEASE TAKE THE TIME YOU NEED TO REVIEW THE FOLLOWING INFORMATION
COBALT INDUSTRIES - FOOD AND DRINK
-----------------------------------------
EXPERIMENTATION CONTINUES TO ERADICATE THE AGGRESSIVE NATIVE WILD YEAST - IN THE MEANTIME, USE SALT TO PROTECT RAW FOOD FROM ROT
IF SALT IS UNAVAILABLE, SPREAD THE FOOD TO PREVENT CROSSCONTAMINATION
THE SUBJECTS HAVE FOUND THAT THE ISLAND'S BERRIES PRESERVE WELL SALTED AND COOKED INTO A JAM
THE SUBJECTS' RECENT MUTINY HAS MADE FISHING A COMPLICATED ENDEAVOR. THE FISHERS TOLERATE US BUT IT'S CLEAR THEY'VE CHOSEN A SIDE
THE NANOCRYSTALLINE NATURE OF LOCALLY SOURCED SALT MAKES IT IMPOSSIBLE TO PACKAGE FOR SALE, BUT IT CAN BE TRADED IN PERSON
THE LOCAL FAUNA IS BOTH DELICIOUS AND DANGEROUS.  AS SUCH, YOU TOO WILL RETURN TO THE ISLAND UPON DYING, THROUGH THE STRANGE LOCALIZED CURVATURE. THE JOURNEY IS NOT WITHOUT CONSEQUENCE.
THIS ALSO GRANTS YOU ACCESS TO THE 4D KLEINIAN FOLD - WHAT THE RESEARCH DEPARTMENT HAS COME TO CALL HAMMERSPACE. THE SUBJECTS JUST CALL IT A BACKPACK. THIS SPACE IS CONNECTED TO THE FACTOR AND SEEMS TO FOLLOW YOU THROUGH THE REGENERATION PROCESS.
COBALT INDUSTRIES - A JOINT STATEMENT BY THE COBALT URBAN TRANSIT AUTHORITY AND THE COBALT FORESTRY AND FAUNA INITIATIVE
-----------------------------------------
AS YOU MAY BE AWARE, THE CUTA REPORTED LAST YEAR THAT MULTIPLE CIVILIAN CONTRACTORS HAVE JOINED THE MUTINY, HEADING UNDERGROUND WHERE THE YEAST CAN'T SURVIVE. THE SUBWAY LINES HAVE BEEN INACTIVE SINCE, AND ATTEMPTS TO RECLAIM THE TUNNELS HAVE FAILED. LAST MONTH, THE CFFI BEGAN GETTING REPORTS OF STRANGE ANIMAL BEHAVIOR, INCLUDING CROSS-SPECIES COOPERATION AND SOME WITNESSES REPORTING SUBJECTS HAVE BEGUN DOMESTICATING THE LOCAL WILDLIFE
AFTER SOME WEEKS OF INVESTIGATION, IT BECAME CLEAR THAT THESE ARE IN FACT CONTRACTORS, WHO SEEM TO HAVE ALIGNED WITH THE LOCAL FAUNA, AND SOME OF WHOM SEEM TO HAVE ADAPTED TO THE YEAST. DOCUMENTED CONFLICT BETWEEN THE FAUNA AND THE SUBJECTS SEEMS TO BE ONGOING.  AS SUCH, THE SUBWAYS WILL REMAIN CLOSED UNTIL FURTHER NOTICE, AND UNTIL THE CFFI HAS SUCCESSFULLY CULLED THE LOCAL FAUNA, TAKE CARE NOT TO BE CAUGHT UNGUARDED IN THE FORESTS
COBALT INDUSTRIES - A SHOCKING SURPRISE!  WITH THE ONGOING SECURITY SITUATION, AND IN CONSIDERATION OF YOUR DUTIES, YOU HAVE BEEN PERMITTED TO SABOTAGE SUBJECT ELECTRONIC CAPACITY, AS WELL AS MANIPULATE THE ELECTRIC LAYOUT OF SITES OF FORENSIC INTEREST.
FIREWORKS ARE AN IMPORTANT MEANS OF COMMUNICATION ON THE ISLAND.   THIS ALSO SERVES TO CLAIM POTENTIAL ZONES OF FORENSIC INTEREST
COBALT INDUSTRIES - LOCAL GOVERNANCE AND CRIMINAL CODE
-----------------------------------------
PER COBALT CORPORATE RESOLUTION 27-1.B, MARTIAL LAW IS INSTITUTED ON THE ISLAND.
THE SUBJECTS SEEM TO HAVE ORGANIZED IN SOME SORT OF DECENTRALIZED COMMUNITY. THEY SHOW NO OBVIOUS SIGN OF HIERARCHY, APPARENTLY GOVERNING THROUGH CONSENSUS.   COULD IT BE BECAUSE OF THE REGENERATION PROCESS?  PERHAPS THROUGH CUMULATIVE REGENERATION THEIR COGNITIVE CAPABILITIES HAVE BEEN EXPANDED


“I was thinking about Flux as a reduce operation over time... your stores, they accumulate state in response to these actions. I was thinking of taking this further. What if your Flux store was not a store but a reducer function?” - Dan Abramov
Answer
Redux = (Red)ucer + Fl(ux)
Reducer reduces (state, action) into state - like Array.prototype.reduce()

(arguably) UI usually has more state than the backend

component interactions (child to parent prop, parent to child func)


The earliest book discovered in which appeared indicia which may properly be termed marks of quotation was printed in 1516 at Strasbourg, Alsace (then in Germany), by Mathias Schurer. It was “De Vitis Sophistarum” by Flavius Philostratus. The marks consisted of two commas in the left hand margin of each page outside the regular type measure. They were placed at the beginning of each line in which a quoted passage appeared, and were evidently added after the page was set up, because their alignment varies greatly.

For about 2 weeks I’ve been having some fun with Linux development, mainly using Ruby to build command-line applications. My decisions, to create command-line applications using Ruby instead of GUI applications, were made because of a simple factor: GUI development for Linux is a nightmare, since there isn’t at least one good GUI prototyping tool available to help you design your UI without having to do everything manually.
First I tried Glade which is just a nightmare. It’s extremely complicated to deal with and you have no clue about which control you should use or how to arrange things, and most importantly there’s not a lot of tutorials and documentation for new users to learn how to use it, and how to integrate with other languages.
Then I was told that Qt Creator was an awesome thing, so I decided to give it a try. I’ve created a new test project and selected the Qt Quick option so I could use QML, which is a lot better for a developer with Javascript background like me. One of the things that made me like this was the amount of good documentation and tutorials.
When I started playing with the Designer one of the first things that I noticed was the lack of simple controls like Buttons, this was pretty strange and I thought I haven’t installed all the things needed, but when I searched for it I got this tutorial from Qt itself, which explains how to create a button in QML (from scratch!!). QML is one of the most awesome things I ever seen to build the GUI logic, it’s simple and flexible, the problem is that there isn’t any kind of controls to create real world desktop applications with it.
After that I took a look at wxWidgets, which lacks good documentation and a decent GUI designer. Then after all this horrible nightmare I thought about creating all my UIs using HTML5 and wrapping everything around a GTK WebKit window, but I don’t think this is a good approach since my apps would look like an alien to the system.
Where are the Delphis of modern computing? I remember how easy it was to design UIs using Delphi and with a right-click on the control you could easily attach an event to it’s logic. It’s this kind of IDE that I’m expecting, one that focus on the fact that you don’t need to struggle to create a UI, but instead that you should be able to create the UI fast and easily enough, so you can focus on the most important thing that is your application logic.
Linux is a awesome OS, I’ve been using it since 2007, and it needs/deserves better tools to create awesome GUI applications, this is one of the reasons that developers aren’t porting their apps to Linux. On Mac OS X we have the awesome Xcode that includes a incredibly awesome GUI designer, and on the Windows side we have Visual Studio with a designer that is the best one in my opinion, since it’s easy, flexible, and powerful. Isn’t this the perfect time for a great Linux GUI designer?


Overfitting happens when the parameters of an algorithm are fine-tuned to fit the detail and noise of backtesting data to the extent that it negatively impacts the performance of the algorithm on new data. The problem is that the parameters do not necessarily apply to new data and thus negatively impact the algorithm's ability to generalize and trade well in all market conditions.
| Data Practice | |
|---|---|
| Data Dredging | Performing many statistical tests on data and only paying attention to those that come back with significant results. |
| Hyper-Tuning Parameters | Manually changing algorithm parameters to produce better results without altering the test data. |
| Overfit Regression Models | Regression, machine learning, or other statistical models with too many variables will likely introduce overfitting to an algorithm. |
| Stale Testing Data | Not changing the backtesting data set when testing the algorithm. Any improvements might not be able to be generalized to different datasets. |
An algorithm that is dynamic and generalizes to new data is more valuable to funds and individual investors. It is more likely to survive across different market conditions and apply to new asset classes and markets.

FG, Obaseki synergise to improve federal roads in Edo
Our Reporter
The Minister of Works and Housing, Mr. Babatunde Fashola, has said that the Federal Government is in talks with Governor Godwin Obaseki on how to improve federal roads in the state.
The Minister who disclosed this during a book presentation at the University of Benin (UNIBEN), Ugbowo, Benin City, said the President Muhammadu Buhari-led administration will work to improve the experience of commuters plying the roads daily.
“Work on roads is a continuous process and we will make it better,” he said, promising to form strong alliance with the state government to address the bad spots.
The Minister said the problem with the Benin-Auchi Road was how to drain some portions of the road so that the construction work on the road can stand the test of time, adding, “The problem that we have is how to drain the affected section before we spend money to construct it. It is a drainage problem. We want to ensure that when we build the road, water doesn’t wash it away.”

Fashola said the Federal Government has already mobilised for remedial work on the Benin-Warri Road, assuring that it will get better in the coming months as weather conditions improve.
On the permission for state governors to embark on the construction of federal roads across the country, Fashola said there are rules, processes and laws that must be complied with.
According to him, “There are processes and laws that must be followed and complied with. These are Federal Government road. The state can ask to construct such roads and the Federal Government can grant such requests under certain conditions. The president, who is the custodian of the road, must be informed. He must meet in council with Ministers to look at the request”.
He said the responsibility of the Ministry of Works and Housing is to collaborate with every state government to achieve their developmental objectives in line with the ministry’s mandate on road construction.

12.1 "Oh What a Tangled Web We Weave"
This
chapter is the third part of our look at Python Internet programming.
In the last two chapters, we explored sockets and basic client-side
programming interfaces such as FTP and email. In this chapter, our
main focus will be on writing server-side
scripts in Python -- a type of program usually referred
to as CGI scripts. Server-side scripting and its
derivatives are at the heart of much of what happens on the Web these
days.
As we'll see, Python makes an ideal language for writing
scripts to implement and customize web sites, due to both its ease of
use and its library support. In the following two chapters, we will
use the basics we learn in this chapter to implement full-blown web
sites. After that, we will wrap up with a chapter that looks at other
Internet-related topics and technologies. Here, our goal is to
understand the fundamentals of server-side scripting, before
exploring systems that build upon that basic model.
|
As you read the next three chapters of this book, please keep in mind
that they are intended only as an introduction to server-side
scripting with Python. The webmaster domain is large and complex,
changes continuously, and often prescribes many ways to accomplish a
given goal -- some of which can vary from browser to browser and
server to server. For instance, the password encryption scheme of the
next chapter may be unnecessary under certain scenarios, and special
HTML tags may sometimes obviate some work we'll do here.
Given such a large and shifting knowledge base, this part of the book
does not even pretend to be a complete look at the server-side
scripting domain. To become truly proficient in this area, you should
study other texts for additional webmaster-y details and tricks
(e.g., O'Reilly's HTML & XHTML: The
Definitive Guide). Here, you will meet Python's CGI
toolset and learn enough to start writing substantial web sites of
your own in Python. But you should not take this text as the final
word on the subject.

Decapitated Sumatran elephant found dead in Indonesia
PEKANBARU, Nov 22 — A Sumatran elephant was found decapitated with its tusks ripped off in an apparent poaching of the critically endangered subspecies, an Indonesian conservation official said.
The rotting corpse of the 40-year-old male creature was discovered by a plantation worker on Monday in Riau province on Sumatra island.
“The elephant’s head had been cut off and its severed trunk was found a metre away from the body,” chief of the local conservation agency Suharyono, who goes by one name, said in a statement on Tuesday.
Authorities said the mutilated elephant had likely been dead for almost a week, adding that they were looking for those responsible.

Rampant deforestation has reduced the species’ natural habitat and brought them into increasing conflict with humans, while their tusks are prized in the illegal wildlife trade.
Last year, the corpse of an elephant was found with its tusks missing in Aceh province in an apparent poisoning case.
Indonesia’s environment ministry estimates there are fewer than 2,000 Sumatran elephants still in the wild. — AFP

PicoCTF 2019 - Seed sPRiNG
Description
The most revolutionary game is finally available: seed sPRiNG is open right now! seed_spring. Connect to it with
nc 2019shell1.picoctf.com 45107
.
Hints:
- How is that program deciding what the height is?
- You and the program should sync up!
Solution
$ file seed_spring
seed_spring: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=24cf2e205931e9f950290de2fac6cff03e58e3df, not stripped
Okay, test run tiiiiime:
$ ./seed_spring
# mmmmm mmmmm " mm m mmm
mmm mmm mmm mmm# mmm # "# # "# mmm #"m # m" "
# " #" # #" # #" "# # " #mmm#" #mmmm" # # #m # # mm
"""m #"""" #"""" # # """m # # "m # # # # # #
"mmm" "#mm" "#mm" "#m## "mmm" # # " mm#mm # ## "mmm"
Welcome! The game is easy: you jump on a sPRiNG.
How high will you fly?
LEVEL (1/30)
Guess the height: 1
WRONG! Sorry, better luck next time!
From the ltrace
output, we can see an outline of the program:
time(0) =<PHONE_NUMBER>
srand(0x5eb9b3e1, 0x56568fb0, 0xfff4656c, 0x56567776) = 0
printf("LEVEL (%d/30)\n", 1LEVEL (1/30)
puts(""
) = 1
rand(1, 0xfff46564, 0x5eb9b3e1, 1) = 0x9a1b302
printf("Guess the height: ")
The program calls the srand()
and rand()
functions.
- srand takes a seed as argument, which is used to “fix” the next pseudo-random integers generated
- rand gives a new pseudo-random number
The problem is that the seed is probably the output of the time(0)
, which returns the current time. Hypothesis verified by the disassembly of the binary:
push 0 ; timer
call _time
add esp, 10h
mov [ebp+seed], eax
mov eax, [ebp+seed]
sub esp, 0Ch
push eax ; seed
call _srand
Let’s now have a look at how the height is chosen ~~
call _rand
and eax, 0Fh
mov [ebp+random_height], eax
So rand()
is called, only the last byte is kept and then stored in random_height
.
Next, that random_height
is compared to the height entered as input:
mov eax, [ebp+input_height]
cmp [ebp+random_height], eax
jz short increase_level_counter
If both values match, we get to the next level! Otherwise we get the message WRONG! Sorry, better luck next time!
. And we need to guess 30 numbers to get the flag.
The Vulnerability
So, what’s the vulnerability and how do we exploit it?
From the man page for rand and srand:
The rand() function returns a pseudo-random integer in the range 0 to RAND_MAX inclusive (i.e., the mathematical range [0, RAND_MAX]).
The srand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned by rand(). These sequences are repeatable by calling srand() with the same seed value.
srand
configure the initial state of the pseudo-random number generator (PRNG) with a seed, which is just a integer value. For a given seed, the list of integers generated with each call to rand
is deterministic.
The seed used for srand is:
seed = time(0);
The man page for time
says:
time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).
So, if we can have the same seed than the server, then we will have the same sequence of random numbers. And to have the same seed, we need to be synchronized and have the same time than the server.
First things first, let’s hack together a script that can produce a sequence of random numbers, the same way than the binary does.
#!/usr/bin/python3
from ctypes import CDLL
LIBC = CDLL('libc.so.6')
LIBC.srand(LIBC.time(0))
random_num = LIBC.rand()
print(hex(random_num))
Kudos to http://ctfhacker.com/ctf/pwnable/2015/09/07/mmactf-moneygame.html for the original source code. I never thought of using ctypes to call C functions but it’s so elegant and practical :D
To verify the output of our script, we can compare the random number produced to the random number generated by the binary. We can manually check the value of $eax
with gdb:
$ gdb seed_spring
gef➤ b *main+391 // break just after the call to rand, on the and eax, 0Fh
gef➤ run
gef➤ print $eax
$4 = 0x8
But that’s a bit cumbersome, and it’s difficult to type all these commands in gdb and simultaneously run the Python script.
Let’s upgrade our gdb-fu, and paste these commands into script.gdb
:
break *main+391
run
print $eax
quit
Then run gdb with:
$ gdb --command script.gdb seed_spring
And it should print the value generated by rand() /o/. Now, open 2 terminals, and run script.gdb and the Python script simultaneously, be quick! You should have the same values in both terminals.
Now to sync with the server, there are 2 options:
- running on the server directly
- bruteforcing the shift between our computer and the server
Now, we just need to add the netcat connection part and something to sync until we match the seed of the server…
Option 1: Running Directly on the Server
So the first solution to synchronize with the server is to… actually run on the server! This is possible because we have a SSH access on the server and not just the netcat service.
We modify our previous script to print 30 random numbers with rand()
and apply a AND 0xF
on the result.
#!/usr/bin/env python3
from ctypes import CDLL
LIBC = CDLL('libc.so.6')
# Seed srand with time(0)
LIBC.srand(LIBC.time(0))
# generate 30 random numbers
for i in range(30):
print(str(LIBC.rand() & 0xF))
$ scp solve.py<EMAIL_ADDRESS>$ ssh<EMAIL_ADDRESS>kylma@pico-2019-shell1:~$ python3 solve.py | nc 2019shell1.picoctf.com 45107
# mmmmm mmmmm " mm m mmm
mmm mmm mmm mmm# mmm # "# # "# mmm #"m # m" "
# " #" # #" # #" "# # " #mmm#" #mmmm" # # #m # # mm
"""m #"""" #"""" # # """m # # "m # # # # # #
"mmm" "#mm" "#mm" "#m## "mmm" # # " mm#mm # ## "mmm"
Welcome! The game is easy: you jump on a sPRiNG.
How high will you fly?
 You've won! Here is your flag:
Option 2: Bruteforcing the Shift
To sync, the time on the server and the time on our computer must be identical. To find out the difference, we can follow that process:
- Is time(0) on my computer equal to time(0) on the server ? No?
- Is time(0) - 1 on my computer equal to time(0) on the server ? No?
- Is time(0) - 2 on my computer equal to time(0) on the server ? No?
- …
- until time(0) on my computer is equal to time(0) on the server
This translates into a slightly more complicated Python script, which can be broken down into:
- the for loop to bruteforce the shift: In the main function, we have a for loop which generates higher and higher shift values. For each value of the shift, we open a new netcat connection, seed
srand
withtime(0)-shift
and send random numbers until the connection is closed. send_new_number
reads the text sent on the netcat connection and returns a new random number- If we manage to answer with a random number 30 times in a row, then we probably have the flag!
from ctypes import CDLL
from pwn import *
import time
import sys
# global settings
context.terminal = ['termite', '-e']
context.log_level = 'info'
LIBC = CDLL('libc.so.6')
def send_new_number(r, level):
# receive "Guess the height: "
answer = r.recvuntil("height: ")
if level > 0:
print(answer)
# generate a fresh random number
random_num = LIBC.rand() & 0xF
r.sendline(str(random_num))
log.info(f"Sending number {random_num}")
if __name__ == "__main__":
for shift in range(60):
r = remote("2019shell1.picoctf.com", "45107")
# Seed srand with time(0)
LIBC.srand(LIBC.time(0) - shift)
try:
for level in range(30):
send_new_number(r, level)
print(r.recvline())
sys.exit(0)
except EOFError:
print("nope")

It had very weird results that I couldn’t understand at first. Sometimes, it would manage to go up to level 3 but fail on level 4, which doesn’t makes any sense… If the suite of random numbers is the good one, it should match all of them…
I decided to check the current time on my computer and on the server:
Thu May 14 20:51:42 UTC 2020 // date output on the server
Thu 14 May 2020 10:53:44 PM CEST // date output on my laptop
And then it was clear why my script was failing… The server is drifting in tiiiime. Yeah, apparently, I was bruteforcing for a shift under a minute, but it’s actually over 2 minutes right now, with a whooping 122 seconds! Those times where the script managed to go up to level 3 were actually pure luck!
Let’s patch the script to bruteforce a shift between 120 and 130 seconds:
-for shift in range(60):
+for shift in range(120, 130):

## Why ? We had a problem…
When someone shares a piece of knowledge, note takers transcript, in their own way, the same content.
But, we can't pull our efforts together and mutualize, in real-time, our notes.
## …which had not been solved…
Collaborative text editors like Etherpad or Googledocs already exist.
[Tools for collaborative writing](http://c.sarahgarcin.com/champ)
## So we cracked our own stuff…
Our tool’s main goal is to allow a personal note taking and, in the same time, a visualisation of the other contributors’ notes.
This mutualisation produces an online document upgraded by everyone’s work.
## Which practices? Which applications?
- Brainstorming
- Meetings
- Courses
- Conferences
- Festivals
More broadly, people sharing knowledge at the same time, in the same place.
## We could make it a way better
We designed PING based on experiments in real-world context.
But it's not functionnal, it's only a prototype.
Adding keyboards shortcuts
Note takers organisation in real time
Sharing and commenting images
Images linked to timeline
## Thanks :)

Margin Collapse
Top and bottom margins of elements are sometimes collapsed into a single margin that is equal to the largest of the two margins.
This does not happen on left and right margins! Only top and bottom margins!
In this example above, the h1 element has a bottom margin of 50px. The pre element has a top margin set to 20px.
Common Sense would seem to suggest that the vertical margin between the h1 and the pre would be a total of 70px(50px+20px). But due to margin collapse, the actual margin ends up being 50px.

I was born and riased in New Orleans and I honestly thought I would never leave. I came to Seattle with a plan to get my feet wet at a real job, see some sights - the space needle, mt. rainier, fremont troll - maybe make some new friends, and then be home by August.
I pushed my lease back twice to stay for just a few more months. Made plans with friends for when I moved back home. Kept my boss waiting when she made me a full-time offer. I denied it for so long until I finally took a look at the life I built here and realized it was something truly amazing.
It's an overplayed story - girl moves away from home, finds herself - and I'm not sure how I didn't see this coming but I was a girl who moved away from home and I am a girl who found herself because of it. One day I'll come back home but for now Seattle is where I need to be.


I'm exiting that folks from Code the Dream provide information about web-development. Information are structured and understandable. Using this knowledges I'm coding and building my skills. It's an opportunity for me to change my career.

Hello all
I still haven't started my OpenEnergyMonitor system yet but we've recently moved house and all my previous plans have changed as a result.
Our new house has only got electric heating which I guess makes things easier to monitor, but the fact that all heaters are on the main ring main for the flat makes it difficult to pinpoint certain devices.
We have 3 convector heaters which are wired via a fused connection unit into the ring main, and one oil filled radiator which is plugged in a standard socket with a timer. I would also like to monitor the immersion heater which is also wired via a FCU to the ring main. In my opinion not the best option to have so many heaters on the ring main but the landlords electrician recently rewired the place and that's how he had done it.
What sort of options are there for monitoring single appliances? The immersion is the highest current at 3kw, the convector heaters are between 500w-1.5kw. I'm happy and competent enough to do the wiring if necessary, I could even house a transmitter of some kind in a spare pattress box next to each FCU if needed and use a CT sensor around the live cable for each one.
My ideal plan would be to have an emonTX with CT sensors at the consumer unit monitoring all circuits, then individual sensors on heaters and some other appliances, I can then subtract the readings of those from the whole ring main reading and work out what everything else is using.
What do you all suggest? Ideally I'd be looking to spend no more than £20 for each individual sensor if possible but will consider higher if that's unrealistic.
Thanks in advance :)
Re: Best, affordable way to monitor individual hard-wired appliances
£20 per appliance is a bit restrictive if you're thinking of measuring current, but as the appliances you mention are all fixed loads, you probably only need to know whether they are on or off, and you can compute the current / real power knowing only the voltage. So I'm thinking in terms of a JeeNode, you still need a power supply and you still need to detect that the appliance is on, though that is simply done with a neon lamp and a LDR or similar, giving good isolation; or maybe if the JeeNode was powered from the switched side of each appliance, then simply saying "I'm on" at regular intervals would be enough and no input sensor would be needed. I'm assuming your emonTx will report Voltage to allow you to do the power calculation in emoncms.
Re: Best, affordable way to monitor individual hard-wired appliances
Adding another emonTX's seems easiest since they are ready to go. Put a CT on each breaker of interest in the breaker panel and the resulting cost per breaker is not that high.
Otherwise how about JeeNode Micro? Or Moteino? Both will be above 20 however. Not counting the analog front end, calibration, programming time etc.
Re: Best, affordable way to monitor individual hard-wired appliances
JD - That's OK where he has individual feeds, but specifically NOT for the appliances that Fitzy mentions that are all on the same feed.
Re: Best, affordable way to monitor individual hard-wired appliances
Hi Robert - Maybe I don't know what "ring main" is. I assumed that meant "breaker panel" in US terminology. Does it mean something else?
EDIT: I googled it, and it seems "ring main" is something else altogether! I've never seen anything like that here in the US. http://en.wikipedia.org/wiki/Ring_circuit

Processing of related objects (Unit of Work)
XData has supported processing data object mapped to number of tricky related tables. Transactional support is required to apply changes over various but related data objects.
For example we have a business object having one ore more related objects collections. Every one of thous can have related collections of other objects and so on. And some business logic works with this related conglomerate as single complicated entity required submitted into DB using one transaction.
XData is support using transaction, but some non terminal data objects can be inserted inside the same transaction and writing code that can support this case is a non trivial thing.
Common but elegant way to make it simple and clear is a realizing "Unit of Work" pattern. Most of ORM has own realization of this pattern, but XData using this mechanic on right level of business logic - to operate with related conglomerate of business objects. Using of Unit of Work pattern with XData is pure declarative: no custom business logic classes is needed to use it.
Lets describe this by example:
Initialization of new UoW container for new root object is described using static Add method of the Work class:
var rep = dataScope.GetRepository<Model.Patient>(Instance);
var instance = rep.New();
/*
Using static class Work we init UoW container with new root object and describe
collections of related objects. Because of new root object we use Work.Empty
method to initialize that collections without fetching any data.
*/
using (var work = Work.Add(instance,
Work.Empty<Model.Patient, Model.PatientDiagnosis>()
.Empty<Model.Patient, Model.PatientOper>()))
{
if (new PatientWindow { DataContext = instance, Owner = window }
.ShowDialog() == true)
work.Submit(); // submitting UoW container changes
}
Initialization of UoW container for existing object (update):
/*
Using static class Work we init UoW container over existed root object and describe
collections of related objects. Because of root object is exists collections will
be filled from DB using Work.Fill method.
*/
using (var work = Work.Add(patient,
Work.Fill<Model.Patient, Model.PatientDiagnosis>()
.Fill<Model.Patient, Model.PatientOper>()))
{
if (new PatientWindow { DataContext = patient, Owner = window }
.ShowDialog() != true) return;
work.Submit(); // submitting UoW container changes
}
Initialization of single related object inside of UoW container (one-to-one relationship) is described by Add method, that analog to Empty and Fill methods we use before.
UoW container can be initialized with a not only single root object, but using collection of root objects with overloaded Add method that accept an collection (ICollection) of root objects.
To select a single object form UoW container use Get method. This method can accept predicate as parameter to specify unique condition of object selection. After acquiring a single object we can change it (or delete it as explained in followed example):
_patient = work.Get();
_patient.SetDeleted(True);
To select multiple objects from UoW container can be made using Select method:
var newOperations = work.Child<Model.PatientOper>()
.Select(x => x.Date > startDate);
To acquire detail UoW container we can use Child method. This method can accept predicate to select root object when root container has initialized by collection of objects. New related object can be added to detail UoW container using New method we discussed above:
work.Child<Model.PatientOper>()
.New(x => x.SomeField = 42, x => x.OtherField = "some");
Important
Unit of Work realization is not internal part of XData. It can be attached to Your project when this functionality is really needed using separate NuGet package XData WorkSet (UnitOfWork) package.
In addition, the UoW container supports exporting hierarchically constructed objects using the static Export method. At the same time, it is possible to export any selected part of the contents of the UoW container, starting either from the root node or from any container node.
To export a node, it must contain a property of type Guid for storing the object key in the UoW container and another property of type Guid for storing the data layer of the UoW container. These properties should not be included in the mapping.
The GetKey (or it's overload version) and SelectKeys methods are used to get the value of the keys of UoW container objects.
To export an object with child objects, it is necessary to define a property to which it will be used to store an array of child objects (or a child instance for one-to-one relation). Such properties should also not be included in the mapping.
In addition, the bool property can be defined in the child objects to pass the delete flag. Such properties should also not be included in the mapping.
To determine the structure of the exported part of the UoW container, a LINQ-style descriptor is used, the use of which is clear from the example below. Using the descriptor, it is possible not only to determine which child objects should be exported together with the root element, but also what service properties of objects at each level, what information will be filled.
var expInvoice = Work.Export(work.DbLayer, key.Value,
() => Work.Root<Invoice>(z => z.Layer, /* Guid Data scope layer property */
z => z.Key) /* Guid Work set key property */
.With(z => z.InvoiceSpec, /* InvoiceSpec[] child entities array property */
z => z.Key, /* child entity: Guid Work set key property */
z => z.Deleted)); /* child entity: bool delete flag property */
After exporting, this object (and its child objects transferred with it) can be modified somewhere outside the system (for example, on a JS-based Web client) and then applied using the Apply method. In addition to the object itself, the Apply method accepts a descriptor built on the principle similar to that described above.
Work.Apply(inv, () => Work.Root<Invoice>(z => z.Layer, z => z.Key)
.With(z => z.InvoiceSpec, z => z.Key, z => z.Deleted));
Warning
In order to apply changes to the UoW container, the data layer (data scope) on which it is built must not be destroyed like the UoW container itself. XData has internal caching mechanisms that allow them to store and retrieve their instances by layer ID using the GetDataScope and GetWorkSet methods.
Important
Data layers are cached independently of UoW containers and you need to destroy the data layer after removing the UoW container separately!

Rewinding
Rewinding is a method in which you can go back in "time" and look at what the value of a variable was at/around a specific timestep. The Rewind
data structure is a pretty simple structure that allows you to do rewinding however you would like. Since you are able to get the Timestep at any point in your code through the use of NetworkManager.Instance.NetWorker.Time.Timestep
, you can easily store anything into the structure that you need. Below is an example showing you how to get started with rewinding in a practical way.
- Create a C# file in your project
- Name the file
RewindTest.cs
- Open the file and paste the code following these steps
- Create a new scene
- Place a cube in the scene
- Attach the
RewindTeste.cs
script to the cube - Attach a
Rigidbody
component to the cube - Save the scene as RewindTest
- Open the Multiplayer Menu sample scene
- Open the build settings
- Click the Player Settings... button
- Make sure Run in Background is turned on
- Add the Multiplayer Menu Scene as scene (index 0) to the build settings
- Add the RewindTest scene as the second scene (index 1) to the build settings
- Press play
- Host a game
- Wait a second or two
- Press the spacebar
- Check the GET message and what time it was at
- Check the SET message with the closest time to that seen in the get message and you will notice they are a match
using BeardedManStudios.Forge.Networking;
using BeardedManStudios.Forge.Networking.Unity;
using System.Collections;
using UnityEngine;
public class RewindTest : MonoBehaviour
{
private Rewind<Vector3> rewind;
private void Start()
{
rewind = new Rewind<Vector3>(5000);
StartCoroutine(Store());
}
private void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
var timestep = NetworkManager.Instance.Networker.Time.Timestep - 1000;
Debug.Log("GET: " + timestep + " | " + rewind.Get(timestep));
UnityEditor.EditorApplication.isPaused = true;
}
}
private IEnumerator Store()
{
for (;;)
{
var timestep = NetworkManager.Instance.Networker.Time.Timestep;
rewind.Register(transform.position, timestep);
Debug.Log("SET: " + timestep + " | " + transform.position);
yield return new WaitForSeconds(0.5f);
}
}
}
Deeper Dive
You will notice in the above example we do rewind = new Rewind<Vector3>(5000);
. The 5000
in this case is the number of milliseconds to track data. Anything older than 5 seconds from now will be removed for memory constraint purposes. You can put whatever time frame you want here, 5000 may be a bit much (because 5000ms is 5 seconds which is a very long time). The <Vector3>
is the type of data that we are storing into this rewinding structure.
Next you will notice the rewind.Register(transform.position, timestep);
call. This will save the value of transform.position
to the rewind history at the provided ulong
timestep. This adds to the pool of stored data for this specific variable for you to pull from. Note It is not good practice to Register
different Vector3
addresses, so if we are using rewind
for transform.position
we should only pass transform.position
into this variable's Register
method.
Lastly we come to the most important action we can do rewind.Get(timestep)
. There are many different overloads for getting the values near and around a timestep however the simplest method to call is Get
. So let's say you Register
a value A at timestep 3 and a value B at timestep 20. If you were to call Get(10)
then you will get value A returned, however if you called Get(19)
you would get the value B. This is because the value closest to the sent timestamp would be returned.
Other Get Methods
List<T> Get(ulong timestep, out T lower, out T upper)
- If we were following the above example and we passed Get(10, out lower, out upper)
into this method, then lower
would equal 3, upper
would equal 20 and the returned value will be 3. This method is useful for if you want to calculate a median or where the value might possibly be between the two values.
List<T> GetRange(ulong timestep, int count)
- This method will act exactly like the first Get
method we learned about in the Deeper Dive section above; however, it also will return n values before the given timestep. So if we passed in 3 for the count
then we would get a list of values back where the first element is the target value for that timestep and every element after that is the value stored at the last timestep registered.
T GetRange(ulong timestepMin, ulong timestepMax)
- This method allows you to get all values between two timesteps (including the min and the max).

return
and |
live (yes, the OTPCL standard pipe is internally an ordinary
command, so you can call it on its own; you can also define your own
pipe-commands, as detailed below).
funs() = map()
vars() = map()
| 'CMD_return'/2 | |
| 'CMD_|'/2 | |
| '|'/2 | Inline command chaining operator. |
| return/2 | Sets $RETVAL in the given state. |
'CMD_return'(Args, State) -> any()
'CMD_|'(Args, State) -> any()
Inline command chaining operator. Takes the result of the preceding
command (stored in $RETVAL
) and passes it as the first argument to the named
command (the rest of the arguments passed being passed through as additional
arguments to the named command).
OTPCL's parser treats any "free" instance of a pipe character (i.e. unescaped
and not already part of some other word) as a command terminator, so OTPCL
will interpret a line like foo | bar | baz
as equivalent to separately
calling foo
, | bar
, and | baz
(which would in turn be equivalent to baz
[bar [foo]]
). This means that it's possible to define custom commands with
pipe-like behavior, and rather simply, too; for example, to define a |!
command that sends the result of a command to a process:
'|!'([Pid], State) -> {RetVal, State} = otpcl_meta:get(['RETVAL', State), Pid ! RetVal, {ok, State}.Assuming the above function is tied to a command name somehow, one could then call
foo bar baz |! $pid
to send the result of the command foo bar baz
as
a message to the process identified via $pid
.
Sets $RETVAL
in the given state. $RETVAL
will be set to one of ok
(if passed an empty list), the list element (if passed a single-element list)
or the given return value as-is (if passed literally anything else). Because
$RETVAL
is an ordinary OTPCL variable, it's possible to write
functions/commands that read it, allowing for, say, chained operations on an
item (this is, notably, how OTPCL's pipe functionality works; more on that in
the documentation for '|'/2
).

Re: emonCMS send failure: wanted 'ok' but got '
Those error would suggest no users have been created but that raises the question where did you get the apikey from if you haven't created a user yet?
try logging into emoncms (if you have craeted a user) and run the "update and check " from the admin page
Paul
Re: emonCMS send failure: wanted 'ok' but got '
Not sure how to "update and check" couldn't find an admin page on http://emoncms.org
But the same api works fine on a pre-built image. It's only with this new image I built that I'm experiencing this issue.
I noticed the emoncms database is empty, should that be like that?
Re: emonCMS send failure: wanted 'ok' but got '
The log says "emonCMS sending: http://localhost/emoncms/input/bulk.json?apikey=......" this isn't emoncms.org it's sending to "localhost" so the admin tab/page will be found at http://IP.OF.THE.HOST/emoncms.
The emoncms database is usually empty until you access the site via a browser, this is when the tables are created and then a user will be added to the user table when you register your first user. At that point you can log-in and get your apikey to put in emonhub.conf.
each emoncms account has it's own api keys. If you were previously sending data to emoncms.org from oemgateway you can still do that with the same apikey by specifying "http://emoncms.org" in the emoncms settings in emonhub.conf.
If, however you are trying to create a new local emoncms server on the same Pi you will need to resister a new user to get a new api as described above.
You can also do both if you prefer by creating 2 emoncms reporters in emonhub.conf (with different names eg emoncms_remote and emoncms_local) setting one to url = https://emoncms.org with your existing key and the other to url = http://localhost/emoncms and creating user and new apikey as above

Re: emonCMS send failure: wanted 'ok' but got '
@the op
I have been getting the same message, on a new install, however I might be having other issues as I am non-standard.
I found I didn't have a link which stated Admin
I had to log out, then log back in, and at the top-right there was now a link Admin
Clicking it, I do have an option to check the database, and mine was out of date, even though it is a new install and the initiation should have created what it needed.
In addition, I have traced some of my errors that are the same as yours down to:
1) Apache hanging
2) Something is locking out the emoncms user from the SQL database (even though it can edit the database using the emoncms web interface!)
The first can be fixed by
service apache2 restart
The second by
mysqladmin flush-hosts -p
However......
I am running a stock raspbian image, with the git emoncms at master
I am running an external MySQL server.
This is because I have a MySQL instance running with light to moderate use, so I might as well use it for any database servers. It isn't anywhere near overloaded, maybe averaging about 100 cmds per minute.
I naïvely thought that the data would be stored in th SQL database too, maybe some day.....
Just had a thought, the database lockout for my problem might be that I only authorised the user for an ipv4 address, where I also have ipv6
Anyway, I will have a bit more debugging and raise a separate thread if needs be
Re: emonCMS send failure: wanted 'ok' but got '
Thanks Paul, that sorted me out there. I had missed that localhost bit.


Options:
- Composed characters: If checked, use a single character for Greek letters with diacritics whenever possible: for instance, a) (1F00) instead of a + 0) (3B1 + 313). In technical terms, this means that Normalization Form Composition (NFC) is used, rather than Normalization Form Decomposition (NFD).
- Deleting individual diacritics: If checked, backspace deletes one diacritic at a time. For example, a)/ → a) → a. If unchecked, backspace deletes a letter plus all its diacritics. (This is true whether the diacritics are combining or not.)
- Putting diacritics in the correct order: if checked, Greek diacritics will be automatically sorted in the order macron or breve (0_, 0^); then rough breathing, smooth breathing, or diaeresis (0(, 0), 0+); then acute, grave, or circumflex accent (0/, 0\, 0=), then iota subscript (0|).
- Validating diacritics: if checked, a letter can only have one of each type of diacritic. (Type refers to the groups of diacritics that are at the same position in the sort order described above.) This means that your input is ignored if the letter already has that type of diacritic. For instance, typing
a//
will produce a/, not a//, and typinga()
will produce a(, not a(). - Replacing diacritics: this modifies the behavior of validation. Instead of not being able to type another character, you can replace existing diacritics of the same type. For instance, typing a smooth breathing 0) (
)
) after an alpha with rough breathing a( (a(
) will produce alpha with smooth breathing a), because the smooth breathing and rough breathing are of the same type. - Allowing both macron and breve: if checked, a vowel can have both a macron and breve: a_^. When you uncheck this, any macron–breve sequences will be replaced with macrons: a_^ → a_.
Features:
- Shift + backspace deletes a sequence of diacritics without deleting the base character. For example, a_)/| → a. (This works even if the composed characters setting is on.)
Notes:
- Greek question mark ; (37E) is normalized to semicolon ; (3B) and Greek semicolon or colon · (387, ano teleia) to middle dot or interpunct · (B7), so the script uses the latter characters.
- Several features of this script don't function yet in Microsoft Edge.
