READV
Section: Linux Programmer's Manual (2)
Updated: 2014-08-19
Index
Return to Main Contents
NAME
readv, writev, preadv, pwritev - read or write data into multiple buffers
SYNOPSIS
#include <sys/uio.h>
ssize_t readv(int fd, const struct iovec *iov, int iovcnt);
ssize_t writev(int fd, const struct iovec *iov, int iovcnt);
ssize_t preadv(int fd, const struct iovec *iov, int iovcnt,
off_t offset);
ssize_t pwritev(int fd, const struct iovec *iov, int iovcnt,
off_t offset);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
preadv(),
pwritev():
_BSD_SOURCE
DESCRIPTION
The
readv()
system call reads
iovcnt
buffers from the file associated with the file descriptor
fd
into the buffers described by
iov
("scatter input").
The
writev()
system call writes
iovcnt
buffers of data described by
iov
to the file associated with the file descriptor
fd
("gather output").
The pointer
iov
points to an array of
iovec
structures,
defined in
<sys/uio.h>
as:
struct iovec {
void *iov_base; /* Starting address */
size_t iov_len; /* Number of bytes to transfer */
};
The
readv()
system call works just like
read(2)
except that multiple buffers are filled.
The
writev()
system call works just like
write(2)
except that multiple buffers are written out.
Buffers are processed in array order.
This means that
readv()
completely fills
iov[0]
before proceeding to
iov[1],
and so on.
(If there is insufficient data, then not all buffers pointed to by
iov
may be filled.)
Similarly,
writev()
writes out the entire contents of
iov[0]
before proceeding to
iov[1],
and so on.
The data transfers performed by
readv()
and
writev()
are atomic: the data written by
writev()
is written as a single block that is not intermingled with output
from writes in other processes (but see
pipe(7)
for an exception);
analogously,
readv()
is guaranteed to read a contiguous block of data from the file,
regardless of read operations performed in other threads or processes
that have file descriptors referring to the same open file description
(see
open(2)).
preadv() and pwritev()
The
preadv()
system call combines the functionality of
readv()
and
pread(2).
It performs the same task as
readv(),
but adds a fourth argument,
offset,
which specifies the file offset at which the input operation
is to be performed.
The
pwritev()
system call combines the functionality of
writev()
and
pwrite(2).
It performs the same task as
writev(),
but adds a fourth argument,
offset,
which specifies the file offset at which the output operation
is to be performed.
The file offset is not changed by these system calls.
The file referred to by
fd
must be capable of seeking.
RETURN VALUE
On success,
readv()
and
preadv()
return the number of bytes read;
writev()
and
pwritev()
return the number of bytes written.
On error, -1 is returned, and errno is set appropriately.
ERRORS
The errors are as given for
read(2)
and
write(2).
Furthermore,
preadv()
and
pwritev()
can also fail for the same reasons as
lseek(2).
Additionally, the following error is defined:
- EINVAL
-
The sum of the
iov_len
values overflows an
ssize_t
value.
Or, the vector count iovcnt is less than zero or greater than the
permitted maximum.
VERSIONS
preadv()
and
pwritev()
first appeared in Linux 2.6.30; library support was added in glibc 2.10.
CONFORMING TO
readv(),
writev():
4.4BSD (these system calls first appeared in 4.2BSD), POSIX.1-2001.
preadv(),
pwritev():
nonstandard, but present also on the modern BSDs.
NOTES
C library/kernel ABI differences
POSIX.1-2001 allows an implementation to place a limit on
the number of items that can be passed in
iov.
An implementation can advertise its limit by defining
IOV_MAX
in
<limits.h>
or at run time via the return value from
sysconf(_SC_IOV_MAX).
On Linux, the limit advertised by these mechanisms is 1024,
which is the true kernel limit.
However, the glibc wrapper functions do some extra work if
they detect that the underlying kernel system call failed because this
limit was exceeded.
In the case of
readv(),
the wrapper function allocates a temporary buffer large enough
for all of the items specified by
iov,
passes that buffer in a call to
read(2),
copies data from the buffer to the locations specified by the
iov_base
fields of the elements of
iov,
and then frees the buffer.
The wrapper function for
writev()
performs the analogous task using a temporary buffer and a call to
write(2).
BUGS
It is not advisable to mix calls to
readv()
or
writev(),
which operate on file descriptors, with the functions from the stdio
library; the results will be undefined and probably not what you want.
EXAMPLE
The following code sample demonstrates the use of
writev():
char *str0 = "hello ";
char *str1 = "world\n";
struct iovec iov[2];
ssize_t nwritten;
iov[0].iov_base = str0;
iov[0].iov_len = strlen(str0);
iov[1].iov_base = str1;
iov[1].iov_len = strlen(str1);
nwritten = writev(STDOUT_FILENO, iov, 2);

--- layout: post title: "Are You Ready To Launch?" date: 2013-01-30 comments: true ---
Last Week: Before Launching, Build Software People Use
You’ve created a product that people want to use, and now you’re eager to launch. From my experiences launching Understoodit, in May 2012, I’ve compiled a set of steps that helped Understoodit get on several big sites including TechCrunch, Toronto Star, and BetaKit. If you have a large budget hiring a PR firm might be your best bet, otherwise the steps below will help you get started.
If you’re going to catch people’s attention in an app saturated environment, it’s important to communicate what's unique about your app. If you’ve created a todo app, is it for Doctors, Engineers or does it something truly unique? If you can’t figure out why your product is unique it's going to be a tough sell and it will certainly make it more difficult to get the press interested on your launch day.
The unique angle for Understoodit was focusing on its confusion feedback feature (students can click confused, and in real-time the teacher can see what percentage of students are confused). If I had said Understoodit was a "classroom response system", I would have had a much harder time competing for attention.
An important step in preparing for a launch is crafting a press release. If you’ve never written one, or you aren’t a strong writer, I’d recommend hiring someone to write it with you (Vicki So helped me).
My familiarity with Understoodit made it difficult to objectively write about it. When you’re focused on the technical side of your product it can be easy to loose focus on what’s important to prospective users. By asking good questions, Vicki was able to tease out of me what was important about Understoodit and why educators might be interested. She was able to turn a product launch into an interesting story about how I started Understoodit.
Reporters read many press releases each day, make sure yours is interesting, tells a story, and is well crafted.
One of the most important tips Vicki gave me was: send the press release to a specific reporter, not a newspaper or website in general. A reporter who covers education is potentially more interested in Understoodit than the average person handling general enquiries. In preparation for launch I made a long list of reporters that cover education, and on launch day I emailed each of them a quick note with a press release attached. I’d also recommend adding reporters who cover small business and startups to your list, they may also be interested.
In addition to reporters, I contacted a couple local tech bloggers and asked if I could give them a face-to-face demo. This approached allowed me to pitch a reporter at BetaKit, a Toronto-based website that covers startups. They ended up doing an article about Understoodit a day after the launch.
I’m no social media expert, but I can say it played an important role in the early success of Understoodit. Facebook and Twitter were huge sources of traffic, as were social news sites such as Hacker News. Depending on your product’s niche you might have more luck with other social networks such as Pinterest or Instagram. However, for you to have a big impact on sites like Twitter, or Pinterest, it helps to have a lot of followers. Gaining followers takes time and is something you should consider long before you launch.
I owe a lot of Understoodit’s launch success to friends that not only helped me with the press release, but also tweeted, liked and voted up Understoodit on launch day. Friends and family are also critical in getting you over the trough of despair - so be kind to them!
No matter how prepared you are there is a strong component of luck to a successful launch. Was your press release the first that a reporter read, or did they read it after reading 5 others? Was there a major news event on the day of your launch? Did a writer on TechCrunch see your launch on Hacker News? All those things are mostly out of your control but can greatly affect your success. Preparation can mitigate some of those issues. For instance, it’s always a good idea to see if there might be any important news events, or tech announcements, that could overshadow your launch.
After following the above actions, mixed with a healthy dose of luck, I was on the front page of Hacker News, and later that day on TechCrunch. Over a 24 hour period Understoodit received hundreds of registrations. Ultimately, that initial burst of excitement made it possible to get an article in the Toronto Star and the Chronicle of Higher Education.
Next Week: I will cover 3 important metrics that you need watch after launching your product.


Limits¶
Setup¶
Limit methods will be called on the DNS service, an instance of OpenCloud\DNS\Service. Please see the DNS service documentation for setup instructions.
List all limits¶
This call provides a list of all applicable limits for the specified account.
$limits = $service->limits();
Absolute limits¶
There are some absolute limits imposed on your account - such as how many domains you can create and how many records you can create for each domain:
$absoluteLimits = $limits->absolute;
# Domain limit
echo $absoluteLimits->domains;
# Record limit per domain
echo $absoluteLimits->{'records per domain'};
List limit types¶
To find out the different limit types you can query, run:
$limitTypes = $service->limitTypes();
will return:
array(3) {
[0] =>
string(10) "RATE_LIMIT"
[1] =>
string(12) "DOMAIN_LIMIT"
[2] =>
string(19) "DOMAIN_RECORD_LIMIT"
}
Query a specific limit¶
$limit = $service->limits('DOMAIN_LIMIT');
echo $limit->absolute->limits->value;
>>> 500


Get a contingency table (or confusion matrix)and compute the IAA measures
such as observed agreement, category specific agreements, Cohen's Kappa, and
S&C's Kappa.
Compute the IAA(inter-annotator agreements), including the observed
agreement, category specific agreeement, several variants of Kappa such as
Cohen's Kappa, and the F-measures between the annotators (see the GATE user
Guide for detailed explanations about those measures).

ARVR Academy is an organization dedicated to diversity and inclusion in AR and VR through education and
professional development efforts to make the ARVR industry more accessible to people of all backgrounds.
We seek to increase more representation of people from underrepresented communities inclusive of
entrepreneurial, technical, and creative roles in the industry. We are working towards an open sourced
curriculum of immersive technologies, and aim to help anyone, regardless of prior experience or background,
find their spot in the growing AR and VR industries.
Frequently Asked Questions
Q: What is the expected cost for the academy series?
Our goal with this series
is to keep the series as accessible as possible. Our current plan is to charge a fee of $120 for
a six class series, but we do also offer partial and full scholarship options for those who are unable
to cover the cost of the labs.
Q: What prerequisite knowledge do I need to have?
We firmly believe that all
backgrounds are relevant to the fields of AR and VR. No prerequisite knowledge is needed, though
participants may enjoy reading about 3D modeling or game development prior to attending.
Q: Where will this be held?
In 2016, we hosted classes in the San Francisco
Bay Area, with 4 course series run in San Francisco and the South Bay. We are expanding to New York
City as of Spring 2017. We are looking to expand globally as quickly as we can to establish a network
worldwide of similar initiatives to teach the fundamentals of immersive technologies to aspiring
professionals in the AR/VR industry. We encourage you to join the interest list regardless of location,
to stay updated as we work on bringing the courses to a city near you. If you or an organization
you know is interested in hosting introductory courses in your city, please reach out and let us
know.
Q: When will the next series of classes begin?
Dates vary by location, but our
first Spring series will begin in March in New York City. We are currently accepting applications
for our New York class here!

CustomObject¶
-
class
flopt.custom_object.
CustomObject
(func, variables)[source]¶ Objective function from using user defined function.
- Parameters
func (function) -- objective function
variables (list) -- variables
Examples
We have the objective funcion \(simulater(a, b)\) where simulater is a black box function, a and b are continuous variable. In this case, we can input objective function into Problem by using CustomObject as follows.
a = Variable('a', cat='Continuous') b = Variable('b', cat='Continuous') def user_simulater(a, b): return simulater(a, b) obj = CustomObject(func=user_simulater, variables=[a, b]) prob = Problem('simulater') prob += obj
Note
The order of variables in the variables list must be the same as the func argument. (However even the name does not have to be the same.) In the case that objective function is simulater(a, b) where a is integer variable and b is the continuous variable,
x = Variable('x', cat='Integer') y = Variable('y', cat='Continuous') def user_simulater(a, b): return simulater(a, b) obj = CustomObject(func=user_simulater, variables=[x, y])
In addition, we can use some operations ("+", "-", "*", "/") between CustomObject and Variable, Expression and CustomObject.
>>> def user_func(x): >>> return x >>> a = Variable('a', iniValue=3) >>> obj = CustomObject(user_func, [a]) >>> obj.value() >>> 3
CustomObject + Variable
>>> b = Variable('b', iniValue=1) >>> obj_b = obj + b # 3+1 >>> obj_b.value() >>> 4 >>> obj_b.variables >>> [VarElement("a", -10000000000.0,<PHONE_NUMBER>0.0, 3), VarElement("b", -10000000000.0,<PHONE_NUMBER>0.0, 1)]
CustomObject + Expression
>>> c = Variable('c', iniValue=2) >>> obj_bc = (b+c) + obj # (1+2)+3 >>> obj_bc.value() >>> 6 >>> obj_bc.variables >>> [VarElement("a", -10000000000.0,<PHONE_NUMBER>0.0, 3), VarElement("b", -10000000000.0,<PHONE_NUMBER>0.0, 1), VarElement("c", -10000000000.0,<PHONE_NUMBER>0.0, 2)]
CustomObject + CustomObject
>>> def user_func2(y): >>> return y >>> obj2 = CustomObject(user_func2, [b]) >>> obj2.value() >>> 1 >>> obj_sum = (obj + obj2) # 3+1 >>> obj_sum.value() >>> 4 >>> [VarElement("a", -10000000000.0,<PHONE_NUMBER>0.0, 3), VarElement("b", -10000000000.0,<PHONE_NUMBER>0.0, 1)]


Doby Grid is stand-alone module (part of the Doby JS framework) for rendering a dynamic, data-driven grid. It's basically a <table>
element on steroids.
Doby Grid is currently in beta and still has several known issues. At this stage, there are several users of Doby Grid in production apps, but bugs and issues are still to be expected.
We're looking for beta testers who are interested in contributing to the development and testing of the library. Feel free to give it a spin and let us know what's missing.
If your grid is rendered inside an invisible element, or an element that is resized - you will need to manually call the resize() method to correct the rendering. Window resizing is auto-detected however.
Grab the latest version from https://github.com/globexdesigns/doby-grid/releases.
Doby Grid is made up of two files (doby-grid.js and doby-grid.css) and well as a theme package. You can choose which theme to download and use. You may also want to grab https://github.com/globexdesigns/doby-grid/tree/master/assets for images.
Then include it into your app either via Require JS, or by adding <script> and <link> tags to load in the Javascript and CSS files after the required dependencies.
Then simply call:
new DobyGrid({...}).appendTo($(document.body))
Change logs for our releases can be found here: https://github.com/globexdesigns/doby-grid/releases.
If you find a bug, or want to request a new feature, or just need help getting going - please use our GitHub issues page at https://github.com/globexdesigns/doby-grid/issues
Doby Grid is an Open Source community-driven project. We're always looking for help: both testing and development. If you'd like to get involved please let us know at<EMAIL_ADDRESS>The Backbone is used for in Doby Grid for two reasons:
1) To make use of Backbone's great event objects for generating custom events 2) To easily integrate Doby Grid into the Doby framework
You can easily use another MVC module in your application, but Doby Grid needs Backbone to do its internal processing. If you're not a fan of Backbone -- don't worry -- it shouldn't affect anything you may be doing in your app with other frameworks, and its overhead is quite small.
Doby Grid was indeed started as a fork of SlickGrid https://github.com/mleibman/SlickGrid but quickly evolved far beyond that. SlickGrid gives you module pieces and a raw foundation for building a grid, and expects you to fill in a lot of the blanks. This is simply too much work for what we wanted to do, so we created Doby Grid that packages the great work SlickGrid started into a nice single package requiring minimal out-of-the-box configuration.
Additionally, there are several other key differences. Doby Grid:
Doby Grid tries to find a balance between performance and usability while offering developers ways to control which features they want to enable at a potential performance cost.
Also, the SlickGrid project is now dead.
Nope. BackGrid https://github.com/wyuenho/backgrid has Backbone at its core for everything. Although it offers great flexibility because of the simplicity of having a Backbone API -- putting Backbone into the heart of the grid processing has made it much slower in processing your data sets. Doby Grid tries its best to keep up to the speed standards of SlickGrid.
Not really. SlickBack https://github.com/teleological/slickback is a bridge between Backbone and SlickGrid. It tries to make the two work together nicely. Doby Grid doesn't require you to use Backbone or SlickGrid in your web application.
You have to attach the event to the whole grid and then isolate the cell you want. Attaching events is expensive so all events are attached to the container and then filtered down to the cell you want to focus on.
grid.on('click', function (event, args) {
if ($(event.target).hasClass("my-button")) {
var item = args.item;
}
});
This would require the grid to be rendered with DOM references - making it much, MUCH slower. If you want to use Doby Grid you must assign events as shown in the question above.
If delegating events isn't enough, then you can use post-processing as demonstrated in the post-processing example. See the postprocess Column Option for documentation. Keep in mind that this is going to have a very significant rendering performance hit and is not recommended on large grids.
And just to be clear -- do not use this for trying to assign events to your cell. It won't work and will only make your grid slow. All those references will be wiped when the grid is re-rendered or scrolled. Don't bother.
Partially.
The project is supported by several organizations which have teams dedicated to driving the project forward. However, the funding we receive is used only for fixing bugs and adding features that are needed for the requirements of the organizations. Anything outside the scope of their work is community-driven.
Doby Grid does not support Internet Explorer. Don't bother posting bug reports. If it's something that affects all browsers - definitely let us know, but if it's an issue specific to IE6 or IE7 or IE8 or even IE9 -- sorry, Doby Grid is not for you.


I don't know how many people will be cruising over to the triazolam section of erowid, given the vast quantity of way more interesting things, but I did. So I might as well give an account of my experience with this drug. Sorry if this is overly long, but there aren't any other reports here and I don't want any visitors to be disappointed with my description.
My first experience with benzodiazepines was with valium, in doses up to 40 mg. For those who don't know, 40mg will induce confusion and amnesia. Luckily, it won't bother you at the time. 10 or 20 mg MAX is my recommended dosage for valium, but this is a side topic.
Valium might be considered recreational. However, I would not recommend that you take Halcion before you go to a party. It is too gentle of a drug to be recreational, and higher doses make you forget things. Its soft nature is what makes it so great for sleeping.
Most of the literature groups Halcion along with other sleep aids like Ambien (which is the devil, IMHO) by saying that it should not be taken for more than two weeks, or addiction will occur. This may well be true generally, but I have been taking Halcion for about a year now, with no signs of addiction. At one point, after three months of nightly usage, I quit cold turkey without any of the ill effects described in the literature - hallucinations, chills, or some such nonsense.
On another side note, during this month off halcion (when I simply hoarded my pills) I used capsules of Valerian root with melatonin, with great success. I still use them now, at doses of about 1 gram Valerian and 6 to 9 mg melatonin.
However, valerian simply cannot compare to the gentle, yet powerful, sedative entity that is Halcion. Halcyon is a word that means:
'A fabled bird, identified with the kingfisher, that was supposed to have had the power to calm the wind and the waves while it nested on the sea during the winter solstice.' or a golden feeling of calm.
I take the pill, and while I lie in bed reading, I suddenly yawn and feel a gentle calm wash over me.  It is not a 'knock-out pill'. It is the noble kingfisher that calms your mind and eases you into a wonderful snooze.
And, this drug does not last 6 to 8 hours like most sleeping pills. It lasts about 2 hours. Halcion puts you to sleep, then leaves you so you can enjoy your rest. It does not seem to have any effect on dream states. Coupled with melatonin it should produce an almost natural sleep without many side effects.
On a more recreational note, this drug works very well up the nose. Halcion fits into my general assumption that the 'little drugs' -those that are measured in small doses and are small pills, such as Ritalin and Demerol - are effective intranasally.
The pills are relatively small - .25 mg being about 7 mm by 4 mm - and the golden colored powder simply disappears up the nose. Little nasal drip, and what does reach my tongue doesn't taste bad.
Effects begin within a few minutes. Subtle, good feeling. The halcyon calm steals over my mind a bit faster, but interestingly, I don't feel as tired. Of course, if I lay down I fall right asleep. But if I stay awake, objects take on a slightly golden tint and make me happier to look at.
Insufflated effects (for me) begin at .125mg, but this might be because I've never tried anything less than that. I have snorted up to 3 pills at once. Or was it 4? I can't remember, and that's the point. Any dosage above about 2 pills, or .5 mg, causes amnesia. It is a very odd sort of amnesia, similar to but milder than valium. I can remember certain parts of what I have done, but everything else is hazy or blank. I can remember important things, like if I did something crazy, but anything mundane (like talking to people or reading a book) is gone.
For example, one night I snorted .25 mg to go to sleep. I wandered around for a bit too long, and made the mistake of thinking I wasn't tired yet. By the way, Halcion twists your thinking process. Anyways, I snorted another pill. And a half. I was up until 3 AM, meticulously counting my large supply of Ritalin until I proceeded to crush 30 of them (300 mg), mix them with water, and put them in my empty Afrin nasal pump spray bottle. My golden-calmed mind didn't bother to consider the fillers that make up most of the pills, and which clogged up the spray pump. All this while half-naked. I eventually realized the stupidity of my ways and laid down to let the kingfisher whisk me away to sleepland.
In summary, for me Halcion is an amazing sleep aid with few side effects or addiction potential, when used in a responsible manner. I must admit that the golden sleep is very psychologically addicting. The drug's subtle effects and short duration make it a much better choice for me than more popular sleep-aids, such as Ambien, which last a long time and can cause amnesia simply by waking up while they are working. The kingfisher is a beautiful and gentle chemical ally. I highly reccomend him.

Pageant is an SSH authentication agent. It holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.
Before you run Pageant, you need to have a private key in *.PPK
format. See chapter 8 to find out how to generate and use one.
When you run Pageant, it will put an icon of a computer wearing a hat into the System tray. It will then sit and do nothing, until you load a private key into it. (You may need to use Windows' ‘Show hidden icons’ arrow to see the Pageant icon.)
If you click the Pageant icon with the right mouse button, you will see a menu. Select ‘View Keys’ from this menu. The Pageant main window will appear. (You can also bring this window up by double-clicking on the Pageant icon.)
The Pageant window contains a list box. This shows the private keys Pageant is holding. When you start Pageant, it has no keys, so the list box will be empty. After you add one or more keys, they will show up in the list box.
To add a key to Pageant, press the ‘Add Key’ button. Pageant will bring up a file dialog, labelled ‘Select Private Key File’. Find your private key file in this dialog, and press ‘Open’.
Pageant will now load the private key. If the key is protected by a passphrase, Pageant will ask you to type the passphrase. When the key has been loaded, it will appear in the list in the Pageant window.
Now start PuTTY and open an SSH session to a site that accepts your key. PuTTY will notice that Pageant is running, retrieve the key automatically from Pageant, and use it to authenticate. You can now open as many PuTTY sessions as you like without having to type your passphrase again.
(PuTTY can be configured not to try to use Pageant, but it will try by default. See section 4.21.4 and section <IP_ADDRESS> for more information.)
When you want to shut down Pageant, click the right button on the Pageant icon in the System tray, and select ‘Exit’ from the menu. Closing the Pageant main window does not shut down Pageant.
If you want Pageant to stay running but forget all the keys it has acquired, select ‘Remove All Keys’ from the System tray menu.
The Pageant main window appears when you left-click on the Pageant system tray icon, or alternatively right-click and select ‘View Keys’ from the menu. You can use it to keep track of what keys are currently loaded into Pageant, and to add new ones or remove the existing keys.
The large list box in the Pageant main window lists the private keys that are currently loaded into Pageant. The list might look something like this:
Ed25519 SHA256:TddlQk20DVs4LRcAsIfDN9pInKpY06D+h4kSHwWAj4w
RSA 2048 SHA256:8DFtyHm3kQihgy52nzX96qMcEVOq7/yJmmwQQhBWYFg
For each key, the list box will tell you:
ssh-keygen
when applied to your authorized_keys
file.
For SSH-2 keys, by default this is shown in the ‘SHA256’ format. You can change to the older ‘MD5’ format (which looks like aa:bb:cc:...
) with the ‘Fingerprint type’ drop-down, but bear in mind that this format is less secure and should be avoided for comparison purposes where possible.
If some of the keys loaded into Pageant have certificates attached, then Pageant will default to showing the fingerprint of the underlying key. This way, a certified and uncertified version of the same key will have the same fingerprint, so you can see that they match. You can instead use the ‘Fingerprint type’ drop-down to ask for a different fingerprint to be shown for certified keys, which includes the certificate as part of the fingerprinted data. That way you can tell two certificates apart.
To add a key to Pageant by reading it out of a local disk file, press the ‘Add Key’ button in the Pageant main window, or alternatively right-click on the Pageant icon in the system tray and select ‘Add Key’ from there.
Pageant will bring up a file dialog, labelled ‘Select Private Key File’. Find your private key file in this dialog, and press ‘Open’. If you want to add more than one key at once, you can select multiple files using Shift-click (to select several adjacent files) or Ctrl-click (to select non-adjacent files).
Pageant will now load the private key(s). If a key is protected by a passphrase, Pageant will ask you to type the passphrase.
(This is not the only way to add a private key to Pageant. You can also add one from a remote system by using agent forwarding; see section 9.4 for details.)
If you need to remove a key from Pageant, select that key in the list box, and press the ‘Remove Key’ button. Pageant will remove the key from its memory.
You can apply this to keys you added using the ‘Add Key’ button, or to keys you added remotely using agent forwarding (see section 9.4); it makes no difference.
Pageant can be made to do things automatically when it starts up, by specifying instructions on its command line. If you're starting Pageant from the Windows GUI, you can arrange this by editing the properties of the Windows shortcut that it was started from.
If Pageant is already running, invoking it again with the options below causes actions to be performed with the existing instance, not a new one.
Pageant can automatically load one or more private keys when it starts up, if you provide them on the Pageant command line. Your command line might then look like:
C:\PuTTY\pageant.exe d:\main.ppk d:\secondary.ppk
If the keys are stored encrypted, Pageant will request the passphrases on startup.
If Pageant is already running, this syntax loads keys into the existing Pageant.
You can specify the ‘--encrypted
’ option to defer decryption of these keys; see section 9.5.
You can arrange for Pageant to start another program once it has initialised itself and loaded any keys specified on its command line. This program (perhaps a PuTTY, or a WinCVS making use of Plink, or whatever) will then be able to use the keys Pageant has loaded.
You do this by specifying the -c
option followed by the command, like this:
C:\PuTTY\pageant.exe d:\main.ppk -c C:\PuTTY\putty.exe
Windows's own port of OpenSSH uses the same mechanism as Pageant to talk to its SSH agent (Windows named pipes). This means that Windows OpenSSH can talk directly to Pageant, if it knows where to find Pageant's named pipe.
When Pageant starts up, it can optionally write out a file containing an OpenSSH configuration directive that tells the Windows ssh.exe
where to find Pageant. If you include this file from your Windows SSH configuration, then ssh.exe
should automatically use Pageant as its agent, so that you can keep your keys in one place and have both SSH clients able to use them.
The option is --openssh-config
, and you follow it with a filename.
To refer to this file from your main OpenSSH configuration, you can use the ‘Include
’ directive. For example, you might run Pageant like this (with your own username substituted, of course):
pageant --openssh-config C:\Users\Simon\.ssh\pageant.conf
and then add a directive like this to your main ‘.ssh\config
’ file (assuming that lives in the same directory that you just put pageant.conf
):
Include pageant.conf
Note: this technique only works with Windows's port of OpenSSH, which lives at C:\Windows\System32\OpenSSH\ssh.exe
if you have it installed. (If not, it can be installed as a Windows optional feature, e.g., via Settings > Apps & features > Optional features > Add a feature > OpenSSH Client.)
There are other versions of OpenSSH for Windows, notably the one that comes with Windows git
. Those will likely not work with the same configuration, because they tend to depend on Unix emulation layers like MinGW or MSys, so they won't speak Windows native pathname syntax or understand named pipes. The above instructions will only work with Windows's own version of OpenSSH.
So, if you want to use Windows git
with an SSH key held in Pageant, you'll have to set the environment variable GIT_SSH
, to point at a different program. You could point it at c:\Windows\System32\OpenSSH\ssh.exe
once you've done this setup – but it's just as easy to point it at Plink!
Pageant can listen on the WinSock implementation of ‘Unix-domain sockets’. These interoperate with the Unix-domain sockets found in the original Windows Subsystem for Linux (now known as WSL 1). So if you ask Pageant to listen on one of these, then your WSL 1 processes can talk directly to Pageant.
To configure this, run Pageant with the option --unix
, followed with a pathname. Then, in WSL 1, set the environment variable SSH_AUTH_SOCK
to point at the WSL translation of that pathname.
For example, you might run
pageant --unix C:\Users\Simon\.ssh\agent.sock
and in WSL 1, set the environment variable
SSH_AUTH_SOCK=/mnt/c/Users/Simon/.ssh/agent.sock
Alternatively, you can add a line to your .ssh/config
file inside WSL that says
IdentityAgent /mnt/c/Users/Simon/.ssh/agent.sock
although doing it like that may mean that ssh-add
commands won't find the agent, even though ssh
itself will.
 So if your Windows machine is multiuser, make sure you create the socket inside a directory that other users can't access at all. (In fact, that's a good idea on general principles.)
Compatibility note: WSL 2 processes cannot talk to Pageant by this mechanism, because WSL 2's Unix-domain sockets are managed by a separate Linux kernel, and not by the same kernel that WinSock talks to.
Start Pageant with the --keylist
option to show the main window as soon as it starts up.
Pageant supports the same -restrict-acl
option as the other PuTTY utilities to lock down the Pageant process's access control; see section <IP_ADDRESS> for why you might want to do this.
By default, if Pageant is started with -restrict-acl
, it won't pass this to any PuTTY sessions started from its System Tray submenu. Use -restrict-putty-acl
to change this. (Again, see section <IP_ADDRESS> for details.)
Agent forwarding is a mechanism that allows applications on your SSH server machine to talk to the agent on your client machine.
Note that at present, whether agent forwarding in SSH-2 is available depends on your server. Pageant's protocol is compatible with the OpenSSH server, but the ssh.com
server uses a different agent protocol, which PuTTY does not yet support.
To enable agent forwarding, first start Pageant. Then set up a PuTTY SSH session in which ‘Allow agent forwarding’ is enabled (see section 4.21.7). Open the session as normal. (Alternatively, you can use the -A
command line option; see section <IP_ADDRESS> for details.)
If this has worked, your applications on the server should now have access to a Unix domain socket which the SSH server will forward back to PuTTY, and PuTTY will forward on to the agent. To check that this has actually happened, you can try this command on Unix server machines:
unixbox:~$ echo $SSH_AUTH_SOCK
/tmp/ssh-XXNP18Jz/agent.28794
unixbox:~$
If the result line comes up blank, agent forwarding has not been enabled at all.
Now if you run ssh
on the server and use it to connect through to another server that accepts one of the keys in Pageant, you should be able to log in without a password:
unixbox:~$ ssh -v otherunixbox
[...]
debug: next auth method to try is publickey
debug: userauth_pubkey_agent: trying agent key my-putty-key
debug: ssh-userauth2 successful: method publickey
[...]
If you enable agent forwarding on that SSH connection as well (see the manual for your server-side SSH client to find out how to do this), your authentication keys will still be available on the next machine you connect to - two SSH connections away from where they're actually stored.
In addition, if you have a private key on one of the SSH servers, you can send it all the way back to Pageant using the local ssh-add
command:
unixbox:~$ ssh-add ~/.ssh/id_rsa
Need passphrase for /home/fred/.ssh/id_rsa
Enter passphrase for /home/fred/.ssh/id_rsa:
Identity added: /home/fred/.ssh/id_rsa (/home/simon/.ssh/id_rsa)
unixbox:~$
and then it's available to every machine that has agent forwarding available (not just the ones downstream of the place you added it).
You can add keys to Pageant without decrypting them. The key file will be held in Pageant's memory still encrypted, and when a client program first tries to use the key, Pageant will display a dialog box prompting for the passphrase so that the key can be decrypted.
This works the same way whether the key is used by an instance of PuTTY running locally, or a remote client connecting to Pageant through agent forwarding.
To add a key to Pageant in this encrypted form, press the ‘Add Key (encrypted)’ button in the Pageant main window, or alternatively right-click on the Pageant icon in the system tray and select ‘Add Key (encrypted)’ from there. Pageant will bring up a file dialog, in just the same way as it would for the plain ‘Add Key’ button. But it won't ask for a passphrase. Instead, the key will be listed in the main window with ‘(encrypted)’ after it.
To start Pageant up in the first place with encrypted keys loaded into it, you can use the ‘--encrypted
’ option on the command line. For example:
C:\PuTTY\pageant.exe --encrypted d:\main.ppk
After a key has been decrypted for the first use, it remains decrypted, so that it can be used again. The main window will list the key with ‘(re-encryptable)’ after it. You can revert it to the previous state, where a passphrase is required, using the ‘Re-encrypt’ button in the Pageant main window.
You can also ‘re-encrypt’ all keys that were added encrypted by choosing ‘Re-encrypt All Keys’ from the System tray menu. (Note that this does not discard cleartext keys that were not previously added encrypted!)
CAUTION: When Pageant displays a prompt to decrypt an already-loaded key, it cannot give keyboard focus to the prompt dialog box. As far as I know this is a deliberate defensive measure by Windows, against malicious software. So make sure you click in the prompt window before typing your passphrase, or else the passphrase might be sent to somewhere you didn't want to trust with it!
Using Pageant for public-key authentication gives you the convenience of being able to open multiple SSH sessions without having to type a passphrase every time, but also gives you the security benefit of never storing a decrypted private key on disk. Many people feel this is a good compromise between security and convenience.
It is a compromise, however. Holding your decrypted private keys in Pageant is better than storing them in easy-to-find disk files, but still less secure than not storing them anywhere at all. This is for two reasons:
Similarly, use of agent forwarding is a security improvement on other methods of one-touch authentication, but not perfect. Holding your keys in Pageant on your Windows box has a security advantage over holding them on the remote server machine itself (either in an agent or just unencrypted on disk), because if the server machine ever sees your unencrypted private key then the sysadmin or anyone who cracks the machine can steal the keys and pretend to be you for as long as they want.
However, the sysadmin of the server machine can always pretend to be you on that machine. So if you forward your agent to a server machine, then the sysadmin of that machine can access the forwarded agent connection and request signatures from any of your private keys, and can therefore log in to other machines as you. They can only do this to a limited extent - when the agent forwarding disappears they lose the ability - but using Pageant doesn't actually prevent the sysadmin (or hackers) on the server from doing this.
Therefore, if you don't trust the sysadmin of a server machine, you should never use agent forwarding to that machine. (Of course you also shouldn't store private keys on that machine, type passphrases into it, or log into other machines from it in any way at all; Pageant is hardly unique in this respect.)

Former Zinara boss Taranhike jailed
Former Zinara finance director Simon Mudzingwa Taranhike has been jailed for an effective 15 months after being found guilty of criminal abuse of office.
by Prosper DembedzaTaranhike abused the Zinara fuel facility and authorised the issuance of 1 800 litres of petrol (Redan Puma) coupons to ZBC journalist Davison Vandira in April without following due procedures, prejudicing his employer of fuel then worth $6 354.
Harare regional magistrate Mr Hosea Mujaya initially sentenced Taranhike to 30 months in prison before suspending six months on condition of good behaviour.

Another nine months were suspended on condition that Taranhike pays back the 1 800 litres of fuel to Zinara before December 31 this year.
In passing sentence, Mr Mujaya said he took into consideration that Taranhike was a first offender and a family man.
Mr Mujaya said it was true that Taranhike did not directly benefit from the commission of the offence.
He further stated that Taranhike lost his job as a result of the offence.
Mr Mujaya said the court could not turn a blind eye on corrupt activities and should pass an exemplary sentence.
In mitigation, Taranhike’s lawyer Ms Purity Chikangaise said her client was a first offender and a father of three. She told the court that Taranhike was a qualified chartered accountant.
Ms Chikangaise told the court that Taranhike was a hypertension patient who takes medication three times a day.
“Because of this conviction, my client’s employment opportunities have been thrown down the drain,” she said.
Ms Chikangaise told the court that the conviction on its own had a negative impact on her client in his social life since he was a well-respected person.
She asked for leniency, saying a custodial sentence would be too harsh for a first offender.
“The court should consider a fine in this matter because indeed it is a fine-able offence, especially putting all the circumstances of the case in total,” she said.
Asked by Mr Mujaya whether it was appropriate to consider restitution as part of the sentence, Ms Chikangaise agreed saying her client was in a position to restitute the fuel coupons if need be.
In aggravation, prosecutor Ms Netsai Mushayabasa said corruption has become rampant in the country and the court should consider stern measures to send a message to would-be offenders.
Ms Mushayabasa said a fine or community service would trivialise the offence. The Herald

If anyone asks me, the most important event in EESTEC LC Ljubljana is JobFair, literally a fair where employers from various companies can meet students and potentially find new employees. For ten years in a row the fair has been the pleasure and the pain of many organisers.
This year, however, is different. After a long time, EESTEC LC Ljubljana again has the pleasure of hosting the international Congress.
Since the two events are separated by only one month, the decision has been made to combine them and improve the PR aspect of both of them. They will be connected through a series of events, lectures and workshops of sort.
To make the connection feel more natural and easier to explain, we started brainstorming about potential ideas for an overarching topic that would bind the events together and strengthen the tie between (the kingdoms of men and elves xD) the series of otherwise loosely connected events.
The topic was soon chosen. Digitalization. Digitalization could roughly be described as the transformation from analog to digital, but can also be seen as a step into a new era of industry, a step into the future. We chose this topic because it has a lot of compelling features and started working towards the goal of making it a reality. As is true for any story, this one also needed a catchy name. That is how the Wind of Digitalization was born.
The goal of the connecting story was to bring digitalization closer to students and teach them about different aspects of it. We want to bring up the security pros and cons that come with digitalization, a discussion on the current state of digitalization in companies, government, organisations in Slovenia and much more. To be quite optimistic and a bit naive: we want to educate students on a level they don’t get to see in the classroom.


Customization provides a means for modifying the appearance and behavior of a bean within an application builder so it meets your specific needs. There are several levels of customization available for a bean developer to allow other developers to get maximum benefit from a bean's potential functionality.
The following links are useful for learning about property editors and customizers:
PropertyEditor
interface
PropertyEditorSupport
class
PropertyEditorManager
class
Customizer
interface
BeanInfo
interface
A bean's appearance and behavior can be customized at design time within beans-compliant builder tools. There are two ways to customize a bean:
A property editor is a tool for customizing a particular property type. Property editors are activated in the Properties window. This window determines a property's type, searches for a relevant property editor, and displays the property's current value in a relevant way.
Property editors must implement the PropertyEditor
interface, which provides methods to specify
how a property should be displayed in a property sheet. The following figure
represents the Properties window containing
myBean1
properties:
You begin the process of editing these properties
by clicking the property entry.
Clicking most of these entries will bring up separate panels.
For example, to set up the foreground
or background
use selection boxes with choices of colors, or press the "..." button
to work with a standard ColorEditor window. Clicking on the toolTipText
property opens
a StringEditor window.
The support class PropertyEditorSupport
provides a default implementation of the
PropertyEditor
interface. By subclassing
your property editor from PropertyEditorSupport
,
you can simply override the methods you need.
To display the current property value "sample" within
the Properties window, you need to override isPaintable
to return true
. You then must override paintValue
to paint the current property value in a rectangle in the property sheet.
Here's how ColorEditor
implements
paintValue
:
public void paintValue(java.awt.Graphics gfx, java.awt.Rectangle box) { Color oldColor = gfx.getColor(); gfx.setColor(Color.black); gfx.drawRect(box.x, box.y, box.width-3, box.height-3); gfx.setColor(color); gfx.fillRect(box.x+1, box.y+1, box.width-4, box.height-4); gfx.setColor(oldColor); }
To support the custom property editor, override
two more methods. Override supportsCustomEditor
to
return true, and then override getCustomEditor
to
return a custom editor instance.
ColorEditor.getCustomEditor
returns this
.
In addition, the PropertyEditorSupport
class maintains a PropertyChangeListener
list, and fires property change event notifications
to those listeners when a bound property is changed.
Property editors are discovered and associated with a given property in the following ways:
BeanInfo
object.
The editor of the title's property is set with the following
line of code:
pd.setPropertyEditorClass(TitleEditor.class);
java.beans.PropertyEditorManager.registerEditor
method.
This method takes two arguments: the bean class type, and
the editor class to be associated with that type.
PropertyEditorManager
searchs for that class's property editor in the following ways:
my.package.ComplexNumber
class,
the property editor manager would search for the
my.package.ComplexNumberEditor
class.
You have learned that builder tools provide support for you to create your own property editors. What other needs should visual builders meet for complex, industrial-strength beans? Often it is undesirable to have all the properties of a bean revealed on a single (sometimes huge) property sheet. What if one single root choice about the type of the bean rendered half the properties irrelevant? The JavaBeans specification provides for user-defined customizers, through which you can define a higher level of customization for bean properties than is available with property editors.
When you use a bean Customizer, you have complete control over how to configure or edit a bean. A Customizer is an application that specifically targets a bean's customization. Sometimes properties are insufficient for representing a bean's configurable attributes. Customizers are used where sophisticated instructions would be needed to change a bean, and where property editors are too primitive to achieve bean customization.
All customizers must:
java.awt.Component
or one of
its subclasses. java.beans.Customizer
interface
This means implementing methods to register PropertyChangeListener
objects, and
firing property change events at those listeners when
a change to the target bean has occurred. BeanInfo.getBeanDescriptor
.


DH_INSTALLCATALOGS(1) Debhelper DH_INSTALLCATALOGS(1) NAME dh_installcatalogs - install and register SGML Catalogs SYNOPSIS dh_installcatalogs [debhelperÂ options] [-n] DESCRIPTION dh_installcatalogs is a debhelper program that installs and registers SGML catalogs. It complies with the Debian XML/SGML policy. Catalogs will be registered in a supercatalog, in /etc/sgml/package.cat. This command automatically adds maintainer script snippets for registering and unregistering the catalogs and supercatalogs (unless -n is used). These snippets are inserted into the maintainer scripts by dh_installdeb; see dh_installdeb(1) for an explanation of Debhelper maintainer script snippets. A dependency on sgml-base will be added to ${misc:Depends}, so be sure your package uses that variable in debian/control. FILES debian/package.sgmlcatalogs Lists the catalogs to be installed per package. Each line in that file should be of the form "source dest", where source indicates where the catalog resides in the source tree, and dest indicates the destination location for the catalog under the package build area. dest should start with /usr/share/sgml/. OPTIONS -n, --noscripts Do not modify postinst/postrm/prerm scripts. NOTES Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts.

Ride-n-Guide is a communication system which enables ride leaders to better communicate with other ride leaders on the ride and pull navigational information from the system. The system enable an always on conference call between the ride leaders. The microphone is mute by defaut and can be switched on when speaking. The GPS directions can be pulled by switching it ON. Two input models viz button-based and gesture-based were designed and evaluated. It was found that sers found the button-based system to be better and felt more confident while using it.
On social group rides, ride leaders provide an analog support infrastructure while they’re on the road. These volunteers serve multiple functions: they scout the route, shepherd riders through foreign neighborhoods, and administer emergency health and mechanical aid. These functions require that the leaders space themselves throughout the long train of riders. This helps them to maintain visual and/or auditory contact with the full group, but it strips them of the means to communicate with one another during the ride.
We propose to build a system that will assist leaders in guiding group participants through a safe and enjoyable ride. This system will permit voice communication among leaders at distances outside auditory range through a hands-free interface. The system will take special note of the unique safety concerns of the leaders’ contexts, ensuring that it does not significantly diminish their ability to respond to their environment.
We conceptualised 3 design alternatives.
| Push to talk | Augmented vision | Wearable Gestures |
|---|---|---|
|
|
|
For the final design we combined the pust-to-talk and gesture based alternatives and designed two input variations for our system which creates a universal conference bridge for all ride leaders to communicate with each other
| Input 1: Button-Based | Input 2: Wearable Gestures |
|---|---|
|
Prototype Input: PTT button (green) - Turns microphone ON/OFF with LED feedback. GPS button (yellow) - Requests navigational directions. Prototype Components: Arduino circuit with two functional physical buttons connected to the PTT experimenter’s (wizard) computer, relaying information on button press. Location: Buttons strapped to handlebars of a stationary bicycle. Output: Pretense of PTT mute/unmute on bone conduction headset. |
Prototype Input: PTT gesture - Turns microphone ON/OFF. Feedback through vibration (2 pulses on, 1 pulse off), and on watch face. GPS gesture - Requests navigational directions. Prototype Components: Pebble watch, application relaying information on gesture to PTT experimenter’s (wizard) computer Location: Watch worn by the user. Output: Pretense of PTT mute/unmute on bone conduction headset |
Due to IRB constraints, evaluation was conducted on a stationary bike using a Wizard of Oz method and simulated virtual ride. Two input conditions were tested for switching the microphone from Mute to Unmute or accessing GPS information.
The conditions were:
~ Button-based system having two buttons one each for microphone and GPS. Feedback through LED
~ Gesture-based system with two gestures one each for microphone and GPS. Feedback through vibrations and visual display on the watch.
| Gesture Condition | Button Condition |
|---|---|
|
|
~ Detachable clip-on buttons which can be put wherever user is most comfortable in using them. ~ Single side bone-conduction headset preferable on the left ear. ~ Visual Output: Using a visual display of GPS information either by mounting the smartphones of the user to the handlebar or attaching an external small screen.
Firstly, the project helped to understand the user centered design process. The idea behind the project was to follow the process and design and evaluate the system. Failure at any step meant improvement in the overall design. Secondly, the project caters to a very specific user segment and has economic potential. The users have been facing the problem and are open to adopting low cost interventions.

My drift towards the very origins of Unix was certain to lead me to the Berkeley Software Distribution (BSD) at some point. Linux was built on Unix principles, but it isn’t Unix in the genetic sense. On the other hand, as rightfully stated on Wikipedia, BSD is Unix, but can only call itself Unix-like due to licensing of the original AT&T UNIX operating system (notice the upper case spelling). Regardless, I decided to take a brave step into this genuine Unix ecosystem.
Much like there are multiple Linux distributions, BSD also has its derivatives – FreeBSD, PC-BSD, GhostBSD (both based on FreeBSD), OpenBSD, NetBSD, DragonflyBSD, etc. The major difference between Linux and BSD is the architecture of the OS. Linux is just the kernel with a loosely attached userland (apps, system daemons, etc.) defined by individual distributions. BSD is a complete operating system (kernel + core userland covering basic functionalities, like storage device mounting and networking). On the FreeBSD website this comparison is nicely outlined a a dichotomy between order (BSD) and chaos (Linux). I myself prefer order!
The other major difference is package management. BSD operating systems are source-first, meaning that the primary mode of software distribution is via source code, together with instructions (Makefiles) and scripts describing how to build it. Since core OS functionalities are covered by the base system, the (admin) user has full control over installed software. On FreeBSD apps can be either compiled from source, selecting optional features through an ncurses menu, or installed as binary packages, much like it is done on most Linux distributions. Because packages are originally built from the Ports Collection (the source tree for software), they work almost seamlessly with software compiled by the user. Almost, because packages bear the default set of features. As soon as we decide to cherry-pick features, it's better to stick to the Ports Collection. Most Linux distributions are binary-first, however some Linux distributions follow the BSDs more closely (Gentoo, Void Linux, CRUX, Slackware, etc.).
The main source of knowledge about FreeBSD is the famous FreeBSD Handbook. Perhaps only the Arch Linux and Gentoo wikis can compare to the completeness of the Handbook, which easily covers over 90% of FreeBSD. I think this is important, because sometimes one might lose Internet connection or even worse and having the Handbook directly accessible on the drive is a life-saver! Also, it means that there is a single source of information one can always refer to when in doubt about the OS.
One last important thing to remember is that while both Linux and FreeBSD are Unix-like operating systems, FreeBSD is NOT Linux.
That sounds absurdly obvious, but it means that many terminal commands native to Linux may not work on FreeBSD or work differently.
Even something as common as cp
(copy) has a slightly different behavior on FreeBSD. In general, the BSDs require a
different mindset and familiarity with their quirks. However, since FreeBSD uses a lot of GNU components, one can expect all of the
major desktop environments and apps to be readily available through the Ports Collection. In fact, the vastness of the Ports
Collection with over 24000 packages easily eclipses smaller Linux projects.


Principal secretary to PM, cabinet secy to hold meeting on Delhi pollution
Besides Delhi officials, the meeting will be attended by representatives of Punjab and Haryana governments via video-conference

Last weekend I’ve got the Prototype Game. I like it a lot and the game play is very enjoying. But all that came did not come such simple. After I installed the game and tried it on me Athlon XP 64 6000+ and GeForce 6500 512 MB system I had probably about 5 FPS in the game. The system still satisfies minimum requirements.
I though that my systems is already old for the game, so I upgrades CPU and graphic card to x4 Phenom 9650 and Radeon 4850 1GB graphic card. I expected at least some improvement in the game experience, to play the game at least a bit smoother… But the hardware upgrade did not change anything (at least visually I could not mention the difference).
And this is at 640x480 resolution with everything set to minimum (though there are no many options in the game itself).
I went to their forum and found that many people have performance issues with this game. And the suggestion to fix it is to disable all HID devices (USB devices) except ones in use (mouse/keyboard).
It is weird but it worked for me. Now I can play the game pretty smoothly at its max.
I probably did not need to upgrade at all. But I like the new system :). I hardly ever need the QUAD processor at home except for gaming. The rating on my Vista is 5.9 which is neither best ever score nor worst. I have 5.9 on each item in the system. On the prev system lowest score was 5.4: HDD; 5.6 - Memory. After upgrading CPU and graphic card I got 5.9 on every item. So far so good. Waiting for the next hungry game.
And one more time, I really enjoy the game… Even knowing that I don’t like so much killing and stuff like that.
I liked the sample video of Prototype game. And want to try it :)
