Graduate students bear as much responsibility as their mentors for ensuring that they are well guided through their degrees, say Hugh Kearns and Maria Gardiner.

Ever since the advent of graduate school, students have complained about their advisers. It is almost an article of faith. The adviser is never available or is too available; gives too much feedback or not enough; is too critical or isn't providing enough direction; and so on. Exchanging horror stories with other students is a great way to bond. But advising goes both ways — and if, after careful reflection on their own studies and progress, students determine that they are not getting the guidance they require, they must address the deficiencies.

It is not surprising that advisers figure large in graduate students' conversations. In 2009, the US Council of Graduate Schools in Washington DC reported survey results showing that 65% of the 1,856 doctoral students who responded identified mentoring or advising as a main factor in PhD completion. Our own research at Flinders University in Adelaide, Australia, and our experience at graduate-student workshops across the world suggest that the adviser–student relationship has a big impact on completion time. It certainly influences whether students are still smiling at the end of their degrees!

Students often assume that once they call someone an adviser, he or she automatically acquires all the skills of advising. After all, if your adviser is the world leader in stem-cell technology, he or she must excel at the seemingly simple task of advising — not to mention possess highly developed interpersonal skills and a keen interest in graduate-student development. Sadly, that is not the case.

Sometimes, advising is a weakness of an otherwise very accomplished scientist. This is not surprising. Mentoring tends to be a private business, and often the only model available is an adviser's own experience of having been advised. If it was good, they decide to copy that style and methodology; if it was bad, they do the opposite. There is no guarantee that either approach will provide the student with the guidance he or she needs.

A proactive approach is necessary. If your adviser isn't looking after you in the way you need, then you need to look after them. At some point in the PhD journey, most graduate students come to an important realization: “This is my thesis. My name is written on the front of it. I need to become the driver.” The sooner the candidate does this, the better. If you're not getting feedback, clear direction or the necessary resources, then you must do something about it. What does this mean in practice? Let us take some examples.

Meetings
A comment we often hear at our workshops is, “My adviser is lovely but he/she is just so busy that we never get to talk about my thesis”. And our response is, “Yes, your adviser is busy. All advisers are busy and will continue to be busy. Regardless, you need to organize meetings where you can get real face time and talk about your thesis.” We're not recommending a quick chat in the coffee room or a brief word in the lab. Nor do we mean a lab meeting.

We mean regularly scheduled meetings focusing on your thesis. You will probably have to schedule them and follow up to make sure that they happen. And when a meeting is cancelled, you will have to reschedule it and persist until it happens.

In our experience, just scheduling the meeting isn't enough. You can't assume that your adviser hosts productive meetings or can intuit what you need to know. You need a specific, uncomplicated agenda that could include such action items as what you've done in the past two weeks; feedback on written work; what you'll do in the next two weeks; the next meeting.


This all sounds very straightforward. But if more students followed these steps, many adviser–student issues could be resolved.
Feedback

Again, in an ideal world, your adviser would be skilled at providing supportive comments, delicate in pointing out areas for improvement and deft at intuitively knowing the level of feedback you seek. But this is a fantasy. One student described her feedback experience as similar to being a victim in a drive-by shooting — she handed over her work, it was riddled with bullets and she was left with a bloodied mess as the shooter drove off.

To be fair, e-mailing a chapter to an adviser and saying “Give me feedback” is like walking into a restaurant and saying “Give me food.” You need to be a bit more specific. When handing over your work, identify the type of feedback you are looking for. You might say, “This is an early draft, so I just want feedback on the overall direction,” or “Please focus on the discussion on page six.” If the feedback you get isn't helpful, ask for more detail. Maintaining your adviser means asking for what you need rather than hoping that he or she will know what to provide.

Managing up
One of the secrets of looking after your adviser is working out what they want — and what most advisers want is a student who comes to them with suggestions and solutions as well as problems, gets things done and makes the job of advising easier. In business this is called 'managing up'. When we work with graduate students we call it the 'care and maintenance' of your adviser.

So although it is natural to complain about your adviser — and can even be cathartic — it is not enough. If your adviser is not giving you what you need, you need to go out and get it.

Затворник и Шестипалый

Виктор Пелевин
***

А ты уверен, что так можно научиться летать?


— Нет. Не уверен. Наоборот, я подозреваю, что это бесполезное занятие.


— А зачем тогда оно нужно? Если ты сам знаешь, что это бесполезно?


— Как тебе сказать. Потому что кроме этого я знаю много других вещей, и одна
из них вот какая: если ты оказался в темноте и видишь хотя бы самый слабый луч
света, ты должен идти к нему, вместо того чтобы рассуждать, имеет смысл это
делать или нет. Может, это действительно не имеет смысла. Но просто сидеть в
темноте не имеет смысла в любом случае. Понимаешь, в чем разница?


Шестипалый промолчал.


— Мы живы до тех пор, пока у нас есть надежда, — сказал Затворник. — А если
ты ее потерял, ни в коем случае не позволяй себе догадаться об этом. И тогда
что-то может измениться. Но всерьез надеяться на это ни в коем случае не
надо.


Шестипалый почувствовал некоторое раздражение.


— Все это замечательно, — сказал он, — но что это значит реально?


— Реально для тебя это значит, что ты каждый день будешь заниматься с этими
гайками, пока не будешь делать так же, как я. А для меня это значит, что я буду
следить за тобой так, будто для меня твои успехи и правда важны.


***

— Слушай, Затворник, ты все знаешь — что такое любовь?


— Интересно, где ты услыхал это слово? — спросил Затворник.


— Да когда меня выгоняли из социума, кто-то спросил, люблю ли я что положено.
Я сказал, что не знаю. И потом, Одноглазка сказала, что очень тебя любит, а ты —
что любишь ее.


— Понятно. Знаешь, я тебе вряд ли объясню. Это можно только на примере. Вот
представь себе, что ты упал в бочку с водой и тонешь. Представил?


— Угу.


— А теперь представь, что ты на секунду высунул голову, увидел свет, глотнул
воздуха и что-то коснулось твоих рук. И ты за это схватился и держишься. Так
вот, если считать, что всю жизнь тонешь (а так это и есть), то любовь — это то,
что помогает тебе удерживать голову над водой.


— Это ты про любовь к тому, что положено любить?


— Не важно. Хотя, в общем, то, что положено, можно любить и под водой. Что
угодно. Какая разница, за что хвататься, — лишь бы это выдержало. Хуже всего,
если это кто-то другой, — он, видишь ли, всегда может отдернуть руку. А если
сказать коротко, любовь — это то, из-за чего каждый находится там, где он
находится. Исключая, пожалуй, мертвых…
Хотя…


— По-моему, я никогда ничего не любил, — перебил Шестипалый.


— Нет, с тобой это тоже случалось. Помнишь, как ты проревел полдня, думая о
том, кто помахал тебе в ответ, когда нас сбрасывали со стены? Вот это и была
любовь. Ты ведь не знаешь, почему он это сделал. Может, он считал, что
издевается над тобой куда тоньше других. Мне лично кажется, что так оно и было.
Так что ты вел себя очень глупо, но совершенно правильно. Любовь придает смысл
тому, что мы делаем, хотя на самом деле его нет.


— Так что, любовь нас обманывает? Это что-то вроде сна?


— Нет. Любовь — это что-то вроде любви, а сон — это сон. Все, что ты делаешь,
ты делаешь только из-за любви. Иначе ты просто сидел бы на земле и выл от ужаса.
Или отвращения.


— Но ведь многие делают то, что делают, совсем не из-за любви.


— Брось. Они ничего не делают.


— А ты что-нибудь любишь, Затворник?


— Люблю.


— А что?


— Не знаю. Что-то такое, что иногда приходит ко мне. Иногда это какая-нибудь
мысль, иногда гайки, иногда ветер. Главное, что я всегда узнаю это, как бы оно
ни наряжалось, и встречаю его тем лучшим, что во мне есть.


— Чем?


— Тем, что становлюсь спокоен.


— А все остальное время ты беспокоишься?


— Нет. Я всегда спокоен. Просто это лучшее, что во мне есть, и когда то, что
я люблю, приходит ко мне, я встречаю его своим спокойствием.

DANCE, DANCE, DANCE...

© 1988 by Haruki Murakami © Д. Коваленин, перевод, 2001 © «Амфора», подготовка текста, оформление серии, 2001

Может быть, это что-то вроде Судьбы. Даже не знаем, как тут сказать поумнее...

— Тенденция? — подсказал я.

— Ага, она самая! Тенденция. Вот мы и думаем... А вдруг, даже начав жить заново, ты все равно бу­дешь делать так же? Раз уж такая тенденция? А если тенденции следовать долго, однажды наступит мо­мент, когда назад уже не вернуться. Поздно. И да­же мы не сможем помочь. Ведь мы умеем только сидеть здесь и все ко всему подключать. И кроме этого — ничего.

— Но что именно я должен делать? — спросил я его еще раз.

— Как мы уже сказали — мы сделаем, что уме­ем. Попробуем правильно тебя подключить, — сказал Человек-Овца. — Но одного этого будет мало. Дальше ты сам должен стараться изо всех сил. Будешь на одном месте сидеть да о смысле жизни думать — ничего не получится. Все пойдет псу под хвост. Это тебе понятно?

— Да это как раз понятно, — сказал я. — Но, черт возьми, что конкретно я должен делать?

— Танцуй, — сказал Человек-Овца. — Пока звучит музыка — продолжай танцевать. Понимаешь, нет? Танцуй и не останавливайся. Зачем тан­цуешь — не рассуждай. Какой в этом смысл — не задумывайся. Смысла все равно нет и не было нико­гда. Задумаешься — остановятся ноги. А если хоть раз остановятся ноги — мы уже ничем не сможем тебе помочь. Все твои контакты с миром вокруг оборвутся. Навсегда оборвутся. Если это случится, ты сможешь жить только в здешнем мире. Посте­пенно тебя затянет сюда целиком. Поэтому никак нельзя, чтобы ноги остановились. Даже если все вокруг кажется дурацким и бессмысленным — не обращай внимания. За ритмом следи — и продол­жай танцевать. И тогда то, что в тебе еще не сов­сем затвердело, начнет потихоньку рассасываться. В тебе непременно должны оставаться еще не за­твердевшие островки. Найди их, воспользуйся ими. Выжми себя как лимон. И помни: бояться тут не­чего. Твой главный соперник — усталость. Уста­лость — и паника от усталости. Это с каждым быва­ет. Станет казаться, что весь мир устроен неправиль­но. И ноги начнут останавливаться сами собой... Я поднял голову и уставился на гигантскую тень за его спиной.

— А другого способа нет, — продолжал Чело­век-Овца. — Обязательно нужно танцевать. Мало того: танцевать очень здорово и никак иначе. Так, чтобы все на тебя смотрели. И только тогда нам, возможно, удастся тебе помочь. Так что — танцуй. Пока играет музыка — танцуй.

Engineers Unveil Particle Accelerator on a Chip

IEEE Spectrum

Zipping ions down a MEMS racetrack could lead to portable particle beams
By Joseph Calamia / March 2011
Image: Yue Shi

This article was modified on 22/02/2011

3 February 2011—Forget for a moment about the quest to build bigger high-energy particle accelerators. Last week, at the MEMS 2011 conference, in Cancun, Mexico, researchers instead explained their efforts to create a smaller one.

Their chip-size cyclotron can guide argon ions with around 1.5 kiloelectronvolts of energy down a 5-millimeter accelerating track before whipping them around a 90-degree turn. The system boosts the ions’ energy by 30 electronvolts. That’s not very much energy, but unlike its larger cousins, this accelerator has no need for bulky magnets and instead uses an electric field set up between parallel electrode guide rails to accelerate and steer its particle beam. The device’s designers at Cornell University, in Ithaca, N.Y., say that with more research, similar electrostatic mini-accelerators might be used in shoebox-size scanning electron microscopes or portable particle-ray guns for cancer treatment.

The Large Hadron Collider, the world’s largest particle accelerator, which is buried underneath the border of France and Switzerland, can slam particles together in collisions that have nine or ten orders of magnitude more energy than the ions that traveled through the tiny Cornell device. "They need that to break open the nucleus and see what’s inside," says Yue Shi, an electrical and computer engineering graduate student who developed the accelerator on a chip.

Instead, Shi, funded by the U.S. Defense Advanced Research Projects Agency, is working to create a device that might accelerate ions to energies of hundreds of kiloelectronvolts on a chip not much bigger than a few square centimeters, and a suitcase-size device capable of accelerating ions to hundreds of megaelectronvolts, in the hopes of developing portable particle accelerators.

Shi constructed three versions of the accelerator—two on silicon-on-insulator (SOI) chips and one on a printed circuit board. Each had a straight, segmented acceleration track and either a 1-, 2-, or 4-mm turning radius. To test the design, she fired a stream of argon ions with around 1.5 keV of energy from a commercial ion source into each chip’s tracks. Electric fields between four segments in each chip’s acceleration track gave the ions a kick before they raced into the turn. Then another electric potential between two electrode curbs pulled ions around the bend. Only those ions with just the right amount of energy made it through. So, by detecting ions at the finish line, Shi confirmed that they truly got a boost.

If a small accelerator based on this design could bestow 1 MeV of energy to ion beams, it would have a broad range of applications, says Amit Lal, who worked with Shi and leads Cornell’s SonicMEMS Laboratory. Lal’s group works to create chip-scale power sources, such as a radioisotope-based generator for powering the electronics in cyborg insects. This particle accelerator is an offshoot of that research.

Lal also foresees more fantastic uses for the device. Doctors already use high-energy particle beams to kill cancer cells, he says, explaining that protons shot at living tissue give off heat as they slow down. Such radiation therapy requires devices that take up an entire room, he says, but tinier accelerators might make treatments more feasible for smaller clinics or allow more localized beams to irradiate fewer healthy cells. "Think of a scalpel with a proton beam coming out of it," he says.

Developing this proof-of-concept device into a commercial tool will first require overcoming some technical hurdles. Right now, the chip accelerates ions from a commercial argon ion source with a 75-micrometer-wide beam. Shi compares shooting that wide source into the accelerating channel to threading a needle, and much of the beam is lost. In the future, she hopes to use on-chip plasma sources to ionize atoms and energize them to around 100 eV before they even enter the electrostatic accelerator. She also notes that the accelerator she presented last week doesn’t focus the beam, which also leads to lost ions. Finally, she points out that the fastest ions that coursed through the accelerator during this initial research only had around 2 keV of energy—not much more than their starting energy of 1.5 keV from the commercial ion source—and that’s still three orders of magnitude lower than what she seeks.

Reaching the 1 MeV goal is certainly possible, she says. Having now shown that the ions can execute tight turns, Shi believes that future designs could navigate the ions repeatedly through accelerating strips for more energy.

The Cornell device is not the only mini-accelerator in development, or even the smallest. Instead of electrostatics, Gil Travish, who is developing a "micro-accelerator platform" at the University of California, Los Angeles, wants to use the electric fields in laser light to speed particles on their way. Travish’s group is starting to build a device that he describes as a 1-µm-thick "sandwich" with two mirrors above and below a gap only one wavelength of light high and several hundred wavelengths wide. As the light from a laser oscillates in that gap, an electron passing through the peak electric field will receive a tremendous boost—around a gigaelectronvolt per meter or a megaelectronvolt per millimeter. His team hopes to start beam tests in a prototype device in the next six months.

Travish says that it’s important to have multiple approaches, such as Cornell’s electrostatic work, for building these tiny particle accelerators. The high frequency of the laser light planned for use in the UCLA device means that only the zippiest of particles would make it through before the oscillating, light-wave-induced electric field reverses. That’s fine for electrons, but the argon ions that Cornell has accelerated, he notes, would need to be moving very quickly to make it through any laser accelerator. Otherwise, "the wave would just wash over the particle, and it would gain almost nothing," he says.

Funded in part by the U.S. Defense Threat Reduction Agency, which protects against the threat of weapons of mass destruction, the UCLA team imagines that their particle beam might also one day appear in medical devices or in unmanned aerial vehicles that could examine suspicious buildings using X-rays. "I think that in the next half decade you’ll start to see a real awakening," Travish says about the possibilities in particle accelerators’ new realm.

Introduction
What Is Windows Vista?
On January 30th, 2007, Microsoft released Windows Vista worldwide. This brand new
operating system serves personal computers, including desktops, laptops, Tablet PCs,
and media centers. So what makes Windows Vista distinct from other Microsoft
operating systems like Windows XP and Windows 2000? Windows Vista was released
more than five years after the release of Windows XP, its immediate predecessor and it
ultimately contains hundreds of new features in addition to various reworked features
from the older operating systems. Above all, Windows Vista focuses on providing a
more dramatic experience with enhanced graphic features and multimedia tools that
allow the user to more easily create audio, visual, and print products.
Why Do I Need This Book?
The purpose of this book is to discuss the complexities of Windows Vista security
features, noted for their dramatic improvement on the features and settings of previous
Windows operating systems, including Windows XP. This book should help you
understand why Windows Vista, the latest operating system from Microsoft, is
particularly advantageous from a security point of view. Reviewing the key features,
weve compiled information about the most commorted nlyproblems repo for this book
and just in case we miss anything, you can check out the list of further resources
pointing you in the direction of books and Web sites that provide further information
about common problems with the platform program.

--------------------------------------- 4

Windows Vista Information
Overview of Windows Vista
What do you really need to know about Windows Vista? The main idea behind Windows
Vista, it seems, was to provide Windows users with a more convenient system that
integrated a heck of a lot of multimedia elements. After all, in the last five years, the
Internet has come a long way and now most regular computer users, during their
online stints, like to make some use of media, whether its by creating a video for
YouTube or just tuning in to their favorite radio station streaming online. Of course,
theres also digital photography. Who hasnt got a digital camera? Windows Vista makes
it easy for the average computer user to make use of these various types of media with
relatively little hassle. It also provides a range of other program upgrades for standard
features like word processing and database management, reducing the extent to which
the lack of Microsoft Office, no longer preinstalled on the Windows systems, is felt.
Purchasing Windows Vista
Believe it or not, one of the most frequently asked general questions about Windows
Vista is What do I have to buy?´ It seems many people are confused about how they
get their hands on Windows Vista and what precisely it means to have this operating
system installed on a computer. Other common questions were going to answer in this
section, purchasing Windows Vista, include questions about editions of Windows
Vista, comparing features, and what disks you need (or dont need, as the case may be)
to prepare yourself in case of a system failure. Computers that come with Windows
Vista operating systems preinstalled will generally have what is called the Windows
Vista Home Basic edition. Many people wonder about upgrades and yes, like most
systems, it is possible to upgrade your edition of Windows Vista. If you have Home
Basic, you can upgrade to either the Windows Vista Home Premier Edition or the
Windows Vista Ultimate. With Windows Vista Business, and you generally have to select
this operating system over the Home Basic when you buy your computer system, then
you can also upgrade to the Windows Vista Ultimate edition if you prefer.
Your best bet, if youre considering an upgrade is to head on over to the Windows Vista
Web site where you can compare the features of the various editions and make a
determination as to whether an upgrade is going to be worth your while. The Web site
address is https://na.windowsanytimeupgradestore.com/WAU_DIRECT/Home.aspx and
you simply follow the link to compare editions; pricing information for the upgrades is
provided there as well.
Since Windows Vista does not always come along with a set of recovery discs, another
common question with regard to purchasing is whether or not you need to pay for or

--------------------------------------- 5

otherwise secure a Windows Vista disc. If you decide to secure an upgrade for your
Vista system then you are likely to receive a disc in the mail as part of your order. In
this case, you are paying for the disc as part of your upgrade. Otherwise, you may have
to make your own recovery discs using blank rewritable CDs. Generally you will receive
a prompt about this close to the time that you start up your computer for the first time
(if its a new computer) or periodically when you are going about using your computer.
Minimum System Requirements
The minimum system requirements for Vista capability are as follows: Processor speed
of 800MHz, memory of 512MB RAM, DirectX 9 capable graphics card, 20GB hard drive
and at least 15GB of free space plus a CD-ROM drive.. The minimum system
requirements for the Vista Premier are stated as follows: Processor speed of 1.0GHz,
1GB RAM, DirectX 9 capable GPU with Hardware Pixel Shader v.2.0, 128MB RAM, 40GB
of hard drive, at least 15 GB, and a DVD-ROM drive.

--------------------------------------- 6

Assessing Windows Vista Configurations
The first step to optimizing your Vista operating system is to make a determination
about the current configurations of your operating system. Its important to have a
deployment plan for assessing your current system and there are key questions that
you will need to answer:
· How compatible is the Vista operating system with the computer and other
devices on your network?
· What applications do you use most often?
· Are the applications you use compatible with Windows Vista?
· Do you need to upgrade to newer versions of the software before upgrading
users' computers?
You need to make a detailed assessment of your system to determine what
components are most significant to your user experience and what components, if any,
are creating problems for you.
To optimize your system there are three or four pointers you need to think about. You
need to think about how regularly you remove junk files from your computer and how
much disk space your regular files are taking up, which files or folders engross your disk
space, and what you can do to increase hard disk space.
One of the best ways to tune up your system start-up processes is to control which
programs open automatically on Windows. Its imp tunorte upan Vist ttao boot menu
and edit context menus of mouse right-clicking. To do this, you generally need to go to
check the properties on the individual applications. You can also customize system
desktop, menus, toolbar, and notifications settings to make your system run faster and
more efficiently.
Tweaking your security options can also improve your desktop, menus, and windows
logon features. You can disable system updates and error reports and hid or restrict
access to specific drives. By limiting the amount of work that your operating system
does by default, you can minimize the amount of time that it takes your system to
operate.
These are general steps that you can at least consider, general pointers you should
keep in mind as you look to explore the ways that you can improve the functionality of
your operating system. Once you have a clear idea about the types of changes you can
make, you can look to identify the specific tweaks and tricks you want to try.

--------------------------------------- 7

Improving Your Windows Vista Experience
Optimization Tweaks
There are many known problems with the Windows Vista operating system as indeed
there are with many systems. Fortunately, enough people spend enough time
addressing these problems; identifying them and searching for ways to resolve them.
Various tweaks and tricks have been developed to speed-up the Windows Vista
operating system, to reveal hidden features, and customize its look and feel. The
purpose of presenting these tweaks and tips here ± summarizing information from the
numerous public forums where this information has been shared ± is to assist Windows
Vista users in optimizing their operating system and ensuring its maximum function.
Everyone uses their computer ± and subsequently their operating system ± for different
reasons. By performing optimizations and tweaks in accordance with the context in
which you use your Vista operating system, you put yourself in a particularly good
position to avoid many of the common problems for hardware, software, and network
features.
Indexing Options for Windows Vista
One of the first and most useful steps for optimizing Windows Vista involves
customizing index options. In its default setting, the Windows Vista index system runs
in the background of the computer and automatically indexes all files in the Start Menu,
the user profile folders, and file set up for online access by default.
One of the problems with the indexing system running in default is that the entire
operating system can be slowed dramatically if files in the Start Menu, user profile
folders, and files set up for online access are changed frequently. Fortunately, Windows
Vista allows the user to adjust the indexing system. One of the most effective steps for
maximizing performance involves disabling the indexing for all locations but the Start
Menu. The only disadvantage to this step is that it takes longer to search around the
rest of your computer for files.
1. Click on the Start Button.
2. Enter Indexing Options.
3. Click Enter and the Indexing Options will load.
4. Click on the Modify button.
5. Click Show All locations.
6. Scroll down and uncheck all options except the Start Menu.
7. Select OK.

--------------------------------------- 8

Speed-up Start Menu Search
Once the general indexing for your computer has been modified, you can work towards
speeding up your Start Menu search. As you perform a search in the start panel search
box, the Windows Vista will search automatically through your file index.
The best way to speed-up your Start Menu search is to narrow the scope of the search
so that it does not include files on the hard drive.
There are several ways to do this:
Option 1:
1. Open registry editor using regedit.
2. Navigate to HKEY_CURRENT_USER > Software > Microsoft > Windows
> CurrentVersion > Explorer and select Advanced.
3. Find and right-click on Start_SearchFiles and select Modify.
4. Set the Value to 0.
5. Restart the Explorer.exe process or reboot the computer.
Option 2:
1. Right-click on the Start Button and select Properties.
2. Click on the Customize button.
3. Uncheck Search Communications.
4. Set Search Files to Don't Search for files.
5. Click OK.
Speed-up Windows Vista's Aero
Windows Vista has particularly impressive graphic features. Unfortunately, the graphic
features tend to make the operating of the Windows Vista system much slower.
There are two things you can do to speed-up the Aero interface in Windows Vista:

Option 1:
Disable Transparent Glass Effect
1. Click on the Desktop.
2. Select Personalize.
3. Select Windows Color and Appearance.
4. Uncheck Enable Transparency.
Option 2:

--------------------------------------- 9

Disable Windows Minimize/Maximize Animation
1. Click on the Start Menu.
2. Enter SystemPropertiesPerformance.
3. Hit Enter.
4. On the Visual Effects tab, uncheck Animate Windows When
Minimizing/Maximizing.
5. Click OK.
Enable ReadyBoost with a USB Storage Device
The ReadyBoost feature enables the use of a USB storage device instead of the slow
paging file for additional storage when the hard drive is low on physical memory (RAM).
To ensure that the ReadyBoost is going to work in Windows Vista as effectively as
possible you will need to have a USB storage device with at least 64MBs of storage, it
must be USB 2.0 compliant, the device must have a minimum read speed of 3.5 MB/s
and the device must have a minimum write speed of 2.5 MB/s.
To enable ReadyBoost, you need to take the following steps:
1. Plug in USB storage device.
2. Go to Computer, right-click on the removable storage device and select
Properties.
3. Click on the ReadyBoost tab.
4. Select Use This Device and set the amount of space to use for the system file.
5. Click OK.
Customization Tweak
A few customization tweaks also help with cutting back the amount of time that the
operating system takes to run.
Stop Applications that Auto-Start on Startup
There are two ways to stop applications that show up on the auto-start as soon as the
individual users log in to Windows Vista. Either use the System Configuration Utility or
the new Software Explorer in Windows Defender to undertaken this change.
First it is possible to make the change using the system configuration utility feature.
1. Click on the Start Button
2. Enter msconfig.
3. Hit Enter.
4. Click on the Startup tab.

--------------------------------------- 10

5. Uncheck items that you do want to auto-start.
6. Click OK.

Alternatively you can use Windows Defender to change the autorun features:
1. Click on the Start Button.
2. Enter Windows Defender.
3. Hit Enter.
4. Click on the Tools from the top menu bar.
5. Click on Software Explorer.
6. Select Show for All Users.
7. Select an application to either Remove or Disable.
Control and Monitor User Activities with Parental Controls
The Parental Controls in Windows Vista allows individuals to control what users can do
while online. In particular, the Paternal Controls allow parents to monitor the activities
of their children using the built-in reports.
The first step to monitoring an account is to establish a user account for the individual
or individuals who are to be monitored. The steps involved in account creation are as
follows:
1. Click on the Start Button.
2. Select Control Panel.
3. Click Add or Remove User Accounts under the User Accounts and Family Safety
area.
4. Select Create a New Account.
5. Create an account ensuring that the Standard user button is selected.
Once the individual account is established, it is necessary to establish parental controls.
To enable these controls, you have to click on the Start Button and select Control Panel.
Under the User Account and Family Safety option, click Set Up Parental Controls, select
the new user account. You need to click the On radio button to get it to start off.

To configure the options controls on the user account you need to open up the
Windows Web Filter. Clicking the Windows Vista Web Filter option you need to check
the blocking option. The blocking option should be enabled.
It is then possible to allow or block various types of Web sites. Its important to check
Only allow Web sites which are on the allow list.

--------------------------------------- 11

You can select options to block web content automatically, applying automatic
restrictions to the type of Web sites that users can access. For maximum protection it
generally works best to select either the High or Medium level works. Clicking on the
radio buttons, it is possible to establish a summary of what is blocked. To block file
downloads it is possible to control downloading files from the Internet. Users can be
prevented from downloading files from the Internet.
Time limits can also be established, along with restrictions on the type of games and
the specific programs that users operate on their account. With a time limit, it is
possible to control how many hours and days children are allowed to work. To
establish the time limits, you only need to click and drag the desired hours and days in
blue to block the times that the user account is active.
Selecting the games played on the account it is possible to select the games options in
the Paternal Controls window. The controls allow or disallow games to be played are
established with setting game rates.
Once the appropriate controls have been established, it is possible to review all user
account activity.
1. Open paternal controls on the account.
2. Select the option to view activities.
3. Review the applications, games, e-mails, instant messaging activities, and
system changes.
4. Click the report option.
5. Navigate the categories on the left side of the window to see relevant activities.
BitLocker Drive Encryption in Sleep Mode
In both the Windows Vista Enterprise and Ultimate editions the security feature,
BitLocker, operates only if the machine is in shutdown mode. The computer must either
be powering off or entering in hibernation mode.
That said, there is definitely some need to perform security checks on a regular basis.
Ordinarily, BitLocker doesn't perform security checks when awaking from sleep mode
but it is possible to set the computer to perform such checks when coming out of
hibernation or after emerging from sleep mode.
To access the BitLocker, which is only available on the two editions of Windows Vista,
Ultimate and Enterprise, you need to go to the Control Panel. There is the option to
select BitLocker Drive Encryption and make appropriate changes to the default settings.

--------------------------------------- 12

Clean Install Windows Vista Using Upgrade DVDs
Upgrading to Windows Vista is one option but you are generally required to have
installed Windows on your computer if you intend to install Windows Vista with Upgrade
DVDs.
In the event that you are having problems upgrading Windows Vista, if you have
already upgraded, you might consider that you need to re-install Windows XP (your
previous full retail Windows system). Fortunately it is possible to resolve issues with
Windows Vista without removing and reinstalling your previous Windows operating
system.
To clean install Windows Vista using upgrade DVDs, you need to take the following
steps:
1. Launch the Windows Vista Upgrade DVD.
2. Begin the setup program.
3. DO NOT enter the product key.
4. Click "Next" and proceed with setup.
5. Install Windows Vista as a 30-day trial.
6. Select the appropriate edition of Windows Vista to continue with the setup.
7. Install program from within Windows Vista.
8. Type in your product key when prompted.
9. Perform an Upgrade or Custom (advanced) install.
10. Choose Custom (advanced) to perform a clean install of Windows Vista.
11. Once setup has completed for the second time, activate Windows Vista normally.

Finally, there are three major developments unique to Windows Vista, all of which
impact the functionality of Windows Vista.
· Boot and Resume:
The Windows Vista operating system is designed to process login scripts, startup
applications, and services in the background to help users to get to work quickly on
their computer. Among the new system features is the advanced Sleep state that
combines the speed used in the Standby mode to allow for the data protection with the
low power consumption of the Hibernate. The result is that the startup process from the
Windows Vista Sleep state takes seconds to start up. As a Windows Vista operating
system starts up, many functions can be processed in the background, affording the
user control over their activities much sooner than in previous versions of Windows.
Instead of shutting down the computer to save power, Windows Vista users can now

--------------------------------------- 13

use the new Sleep state as their default state for turning off their computers. . Going
into the Sleep state, Windows Vista records the contents of memory to the hard disk
while it also maintains the memory. Windows Vista also enters and recovers from the
Sleep mode in a matter of seconds.
· Built-In Diagnostics:
Windows Vista also comes complete with in-built hardware diagnostics, the purpose of
which is to establish when errors are present. The built-in diagnostics of the system are
used to automatically repair the problems and assist with the guiding of the user
through a recovery process. Ultimately, the system serves to eradicate the problem,
whatever it may be.
Although the diagnostic program does not necessarily have the capacity to diagnose all
problems, common problems are at least resolvable with a functioning built-in
diagnostic program. Such problems generally include impending disk failures, memory
problems, and networking issues. Data back-up,
disk replacement, and data restoration are all features that the diagnostics system
allows.
· Automatic Recovery:
When a computer problem is beyond repair, when a failure of the Windows system is
deemed unpreventable, Windows Vista also offers a reasonable solution. Specifically,
the operating system will automatically diagnose and and recover an unbootable
system, turning it into a system that is functional using what is known as the Startup
Repair Tool or SRT. The SRT offers a troubleshooter system to take the user through
the recovery process for no-boot situations step-by-step, minimizing the need for
professional intervention or even major system overall. The general principle of both
the automatic recovery system and indeed the built-in diagnostic systems is to minimize
the extent to which Windows Vista users are vulnerable to lose data should any element
of the operating system fail or otherwise become corrupt. Since start-up problems are
generally recognized as some of the most difficult to resolve, at least for system
administrators, the SRT system is designed to facilitate troubleshooting even in the
event of a start-up problem; when a system boot fails, the system reverts to the SRT,
which performs extensive diagnostics, reviewing the start-up log files to determine the
nature of the problem. This entire process mirrors the general diagnostic process used
to detect problems when the operating system my otherwise be fully functional. As with
the built-in diagnostics and troubleshooter systems of the main operating system, the

--------------------------------------- 14

SRT also offers automatic resolutions or system recovery information to facilitate the
speedy resolution to any systems errors.
Optimizing your system of Windows Vista is decidedly important when you are looking
to make the most of the positives and minimize the negatives of the system. You need
to consider not only how your computer is running in default state (i.e. without any
steps take to optimize the system) but how you use your computer to understand what
steps you can take to most effectively optimize your computer for your purposes.

--------------------------------------- 15

Summary

The purpose of this section is to provide you with a step-by-step review of the
optimization pointers covered in this book. To cut a long story short, it¶s not uncommon
for computer users to overlook the benefits of optimizing simply because the process
strikes them as being too complex.
To keep things simple, these are the steps you can take to ensure that your system is
in top working condition for your purposes:
1. Rate the functionality of your system in terms of the following:
a. How fast your system completes basic tasks like start-up and shut down.
Note if your computer takes a long time to open applications or if there is
an unusual number of interruption as you¶re working on your system
(such as regular error messages, etc).
b. How secure your PC is from security threats. Consider how regularly virus
sweeps are conducted and how regularly anti-spam checkers are updated,
etc.
c. How well does your network operate? Is your operating system
compatible with the various components of your network such as your
printer/scanner/fax/copier, etc? Does your operating system have any
impact upon the speed of your Internet connection? If so, is it slowing
down the connection?
2. Consider how you use your operating system and the extent to which the system
is customized to meet your needs:
a. How compatible is the Vista operating system with the computer and
other devices on your network that you use regularly?
b. What applications do you use most often? Is your system compatible with
these applications? Have you had any problems?
c. Are all of the applications you used on your old system compatible with
Windows Vista? If not, which applications are no longer functioning on
your computer? (You may want to look for upgrades or patches to enable
proper function).
d. Do you need to upgrade to newer versions of the software before
upgrading your computers?
3. Research the in-build system benefits of Windows Vista, such as the built-in
diagnostic systems to determine how easily you can make changes to your
system to improve functionality. Think about the following:

--------------------------------------- 16

a. Can you reorganize the files and directories on your computer to save on
space? Is lack of space or limitation on space having an impact upon the
functionality of your computer?
b. Can you enhance the overall security of your network by establishing
higher levels of security on your User Account and on the other User
Accounts functional on the system?
c. Can you save power by deflecting to the boot and resume option?
d. How good is your system for auto recover of data in the event of a
computer crash? How regularly do you back up your date, etc?
4. Once you have researched the initial options for optimizing your system, you can
take steps to customize and reorganize your system to meet your specific needs.
One of the best ways to ensure that you have a reasonable grasp of the steps
involved in improving your system you can set about the looking for advanced
teaks to boost your system¶s performance.
The Internet is the best place to go for information about custom tweaks and
adjustments to the Windows Vista operating system (or any other operating system, for
that matter) since it provides a ready forum for discussion of computer issues.

the system that there is sufficient reason to question its integrity, but every user is
different. With the right attention paid to your needs you can certainly make your
experience of Windows Vista a positive one.

[gs-devel] Tips for making ps2pdf available (under windows)

Ray Johnston Ray.Johnston at Artifex.com
Mon Apr 6 11:50:18 PDT 2009

Hi Izzy,

The free Microsoft Visual Studio Express C++ can be used to build gs
using: nmake -f psi/msvc32.mak
in a command prompt (assuming that when you installed VS you had it
add the environment variables -- otherwise you might need to run
vsvars32.bat first).

When Ghostscript is installed from the 'gs864w32.exe' it does not add
the path to your PATH environment variable, nor does it add the 'lib'
path.

By default, the install will put 8.64 in "C:\Program Files\gs\gs8.64"
and some subdirectories and will put a 'shortcut' in "Programs" in
the "Ghostscript" group. You can examine the shortcut for gs8.64 to
see exactly where your version was installed. From a command prompt,
you can run Ghostscript using the method from the 'Target' of the
shortcut, which on my installation is:

"C:\Program Files\gs\gs8.64\bin\gswin32.exe" "-IC:\Program
Files\gs\gs8.64\lib;C:\Program Files\gs\fonts"

To use ps2pdf.bat or other lib scripts from a command prompt, right-
click on "My Computer", then click "Properties", then click the
"Advanced" tab and click on the "Environment Variables" near the
bottom and add the following to your 'Path' System variables:

;C:\Program Files\gs\gs8.64\bin;C:\Program Files\gs\gs8.64\lib

by selecting that variable and clicking on "Edit".
An alternate method that only adds these to the path for a single command
prompt is to execute (from the command prompt, before running ps2pdf):

set PATH="C:/Program Files/gs/gs8.64/bin";"C:/Program
Files/gs/gs8.64/lib";"%PATH%"

then typing:

gswin32c -h

should show you that everything is accessible, and typing:

ps2pdf

should say:

Usage: ps2pdf input.ps [output.pdf]
or: ps2pdf [options...] input.[e]ps output.pdf

Best Regards,
Ray Johnston
