A user connects to the internet with their computer.  The internet sends an HTTP signal to the servers. The servers send the info back to the computer. A web browser like I.E., Firefox or Google Chrome, then turns the HTML text into a docutment that can be viewed on your monitor. The internet is basically a collection of HTML text documents.
Basics of HTMLHTML stands for Hypertext Markup Language. HTML is the programming language that allows someone to write code for web pages. This is the "heart" of the web. It is made up of text content. What you see It is also made up of markup. What it looks like. You can reference other documents, create links to other web pages and imbed videos.
HTML MarkupThere are many tags that can change the look of your webpage. A tag looks like this: (opening tag name, contents, closing tag name) This is done with < > instead of ( ) of course. A few of the tags consist of the em tag which italicizes text. The b tag which bolds text. There is also a u tag which underlines text. There are just a few of the many tags available in the HTML language. You can also assign attributes which are values that can link certain web pages to text. Click here to go to Udacity.com. This is an "a" tag which are anchors for linking webpages.
Computers are stupid?I always thought computers were smart until I learned a neat little tidbit from this course. Computers can only do what we tell them to do. We must program them to do the tasks which we require and we must program them correctly. One syntax error can cause an entire program to not function. Syntax errors and simply errors in what was entered into the code.
WhitespaceWhite space refers to the way text looks on a webpage when it is entered as HTML. The text will form one long line without proper formatting. A br tag can be used to add a
line break. This is a void tag meaning it does not require a closing tag. This is referred to as an "inline" element. It creates changes on a line without creating a box.
The p tags creats new paragraphs.
This is referred to as a "block" element. It creates an invisible box around the text that has actual height and width.

We are about to head out on another ride. Come find us and say hello!
Now, the phrase ‘cycling team’ may suggest that we are an elite squad of professional cyclists. We totally could be, but we’d rather drink a lot and commandeer a golf cart.
Here’s a more accurate description of the Perineum Falcon cycling team:
- We do not ride in tight, aerodynamic draft lines at average speeds of 32mph. No. We ride in large, slow, meandering groups averaging somewhere between 0 and 15 mph.
- We ride bikes that cost less than, but weigh approximately as much as, our cars.
- We do not know our lactate thresholds, nor our VO2 Max. We are, however, precisely aware the alcohol content and specific gravity of each of our favorite microbrews.

- We do not shave our body hair outside of what is expected by societal norms or common courtesy.
- We do not take performance enhancing drugs, unless by “performance enhancing drugs” you mean “alcohol”, “ibuprofen” or “caffeine”.
- We do not rehydrate with Cytomax after a hard ride; we rehydrate with with a mouth-watering, hoppy ale. Crotchal chafing is not caused solely by bicycling.
- We do not carb load with pasta; we carb load with a mouth-watering, hoppy ale… and maybe a pork chop. Surprisingly, our body fat percentages do not reside within the single-digit range, except maybe Joe and Mike, but they are effing freaks..
In summary, our team consists of a diverse group of mostly upstanding citizens (depraved bastards) who ride bicycles for fun, and for the companionship of our fellow cyclists (take advantage of drunk biker chicks). We have also been known to dabble in adult big wheel riding and duck racing… and we really like good beer.

Film review by Kevin Patterson
DREAM WITH THE FISHES Rating: *** (out of four) R, 1997 Director: Finn Taylor Story: Jeffrey Young & Finn Taylor Screenplay: Finn Taylor Producers: David Arquette & Jeffrey Young
DREAM WITH THE FISHES does not waste much time in planting itself firmly in some pretty strange territory. It begins with Terry (David Arquette), a neurotic voyeur, spying on Nick and Liz, the couple in an apartment across from his. Nick is ignoring Liz, and when he heads out for the evening, Terry goes to a liquor store, buys himself a bottle of booze, and prepares to jump off the nearest bridge. He's interrupted by Nick, who stops by to ask him for the time, then convinces him that jumping off a bridge is a bad method of suicide, and finally offers to trade a bottle of sleeping pills for Terry's wristwatch. Unbeknownst to Terry, Nick has given him vitamins instead. When Terry realizes what's happened, he follows Nick again, this time to read him off and get his watch back, only to find that Nick is in the hospital, undergoing treatment for a terminal disease that will kill him in another month.
Thus begins one of the weirdest setups for a buddy movie that I can recall. The rest of the film is comparatively tame (but then again, what wouldn't be?): Nick decides he'd rather not spend his last moments in a hospital, and convinces Terry to help him escape so that the two of them can go on a sort of last-chance road trip. They proceed to have numerous little odd adventures, the most amusing of which involves Nick, high on LSD, deciding to steal a fish from a nearby aquarium and set it loose in the sea, before they run out of money and have nowhere to go but back to Nick's hometown. There we are introduced to Nick's dysfunctional family, as well as his old friends and a former girlfriend, while the perpetually timid Terry starts to come out of his shell as he becomes more comfortable with Nick's various acquaintances.
Both Nick and Terry live on fantasy rather than reality. For Nick, it is the fantasy of omnipotence: he's the kind of guy who thinks he's always right, that everyone would be a lot better off if they would just listen to him, and that then he could have all the fun he wants and not have to worry about the consequences. Nick's journey is not one of discovery but one of denial, as he spends most of the film pulling stunts rather than thinking about what his life has meant or resolving old conflicts. Terry's fantasy, on the other hand, is that of withdrawal: his immediate response to any uncomfortable situation is to remove himself from it. He prefers to live vicariously through others, as a voyeur, rather than to make a life for himself, and ultimately this fantasy has manifested itself through the suicide attempt.
Writer/director Finn Taylor has found himself in something of a Catch-22 here: he knows these characters and their shallow, fantasy-prone tendencies so well that the film itself risks becoming shallow and fantasy-prone. Terry learns to enjoy life and realizes he doesn't want to kill himself, but he owes most of his "discoveries" to Nick, who can't really be said to be any more functional than Terry aside from not being suicidal. It's a start, of course, but the events of DREAM WITH THE FISHES would really just be a small step in Terry's development as a more functional and satisfied person.
I am assuming that Taylor knows this and knows that his audience knows this and does not intend for people to walk away thinking all is well for Terry. Accordingly, I'd say DREAM WITH THE FISHES is a moderate success. It's a simple story, nothing monumental, but it's a story that is told with skill and consistency and stays true to itself and to its characters.

That's great! What do you want to do?
There are currently {{ mispackaged }} packages that are Python 3–ready upstream (that we know of), but not quite yet Python 3–ready in Fedora. These are labeled as "mispackaged" in PortingDB.
You can view the mispackaged packages ordered by their last activity, so you can pick one off the top and be relatively sure nobody is currently working on it.
Now open the package in PortingDB (e.g. {{ pkglink(random_mispackaged) }}): The {{ status_badge(statuses['mispackaged']) }} in the sidebar indicates that indeed we are dealing with a mispackaged package.
{% endif %}On the package page in PortingDB, look down the sidebar for the headline RPMs. There you will see all the RPM (sub)packages contained in this package. Sometimes there's just the base package, sometimes it has several subpackages. What we want to know is if there is a (sub)package for Python 3. If there is only a Python 2 (sub)package, then we know that this package needs to be ported.
However, sometimes you will find a package that is still mispackaged even though it already has a Python 3 (sub)package. In those cases, something isn't quite right. Usually the Python 3 subpackage depends on both Python 3 and Python 2. That is unfortunate, because it basically renders the porting effort null.
In either case, look a bit further down on the package page in PortingDB and find a link to the associated Bugzilla report (under Links→bug in the sidebar). Go there and join the discussion. Find out what's the status quo and if anyone is working on it. If not, be the one that opens a Pagure pull request with a fix! The link to the package repository in Fedora Pagure is right next to the Fedora logo on top of the package page in PortingDB (if you are not a Fedora packager yet, you may use remote pull requests or attach a patch to the Bugzilla ticket).
If you don't find a link to Bugzilla, you'll need to investigate the issue and file a bug yourself. A hint on the nature of the problem will usually be provided just under the Fedora heading on the package page.
To aid you in your porting effort, use the Python RPM Porting Guide. If you are investigating why a Python 3 subpackage still depends on Python 2, take a look at the section on shebangs.
When you have a pull request ready, be sure to post a comment about it in the associated Bugzilla report and ask the assigned packager to review and merge it. However, as maintainers can be unresponsive for long periods of time, let us know about your pull request as well so we can merge it if the maintainer is unable.
To let us know, edit the Blocks field of the Bugzilla report and add the string PY3PATCH-AVAILABLE (you can use space as a separator). That way it will appear in our tracking bug for packages with an available patch. If need be, we'll review your pull request and merge it for the maintainer.
After you've done the deed, you deserve your reward! Sadly, the hand of the King's daughter and half of all the kingdom has recently become unavailable (may vary upon location, ask your nearest royal family), but fret not, you can get a badge of honour!
Wait a day or two after the patch is pushed so that the package turns green in PortingDB. Then visit the wiki for Python 3 badges and add a row with your FAS username if it doesn't exist yet. Inside put a link to the Bugzilla report you helped resolve as well a link to the package on PortingDB. You can get 3 badges: for your 1st, 5th and also 10th resolved package!
If you think we forgot to award you a badge, please ping Miro Hrončok (IRC is preferred).
If packaging is just not your thing, don't despair! You can help also by providing information!
There are {{ idle_len }} idle packages which are currently only available for Python 2 and where we don't know of their Python 3–readiness upstream. Do you know that some of them in fact do support Python 3 upstream? Great news! You can let us know by filing a bug!
The {{ blocked_len }} blocked packages are a bit similar, but not quite. These are Python 2–only packages that cannot yet be ported because some of their dependencies are still not ported to Python 3 in Fedora.
If you do know that some of these packages support Python 3 upstream, open the package here on PortingDB and look for the the Fedora headline in the left sidebar. If there's a {{ status_badge(statuses['released']) }} next to it, we already know it's ready upstream. Otherwise, please let us know!
To make PortingDB aware that the package supports Python 3 upstream, please make a pull request on GitHub and provide the information by editing the data/upstream.yaml file. People not acquainted with git can edit the file directly on GitHub by clicking on the little pencil icon on the right side above the contents of the file. Add the following:
package-name: status: released links: bug: http://... homepage: http://... repo: http://... note: | This is a custom note. Please do NOT forget the '|' on the previous line, it's important.
Make sure to put the note inside the file in alphabetical order according to the package name. Including a link is required, chose either a bug, homepage or a repo link type (or a combination thereof). And the note can be any relevant text you wish or it can be omitted.
There are also some packages that just won't be ported, because they were obsoleted by a different package. For example the python package just won't be ported, because the python3 package came along.
If you know of a package which people should stop using and switch to a different one instead, please make a pull request on GitHub and provide the information by editing the data/fedora-update.yaml file. People not acquainted with git can edit the file directly on GitHub by clicking on the little pencil icon on the right side above the contents of the file. Add the following:
package-name: status: dropped note: | Suggested replacement: `other-package-name` You are also encouraged to add a text comment like so.
Make sure to put the note inside the file in alphabetical order according to the package name.
The vast majority of the {{ idle_len }} idle packages are projects that are not yet ported to Python 3 upstream. We in Fedora follow the upstream first rule. If we need to make a change to some software (like port it to Python 3), we need to go upstream and either help the upstream team in the endeavour or offer to make the change for them.
Pick an idle package you would like to work on (for example {{ pkglink(random_idle) }}) and open it in PortingDB. Now you can click on the package name besides the blue Fedora logo towards the top of the page. This will take you to the corresponding entry in the Fedora Package Database and from there follow the link labeled upstream.
Sometimes, however, the upstream link gets broken. In that case go back to the package's page here on PortingDB. Follow the spec file link: what you'll see is a file with the metadata and building instructions for this package. Look for a line beginning with Source0: and try to use its URL (or part of it) to find the upstream project.
First, let's make sure porting is needed as occasionally the package may be already ported, we just don't know about it yet. Look through the information on the website, the issue / bug tracker, the readme files, perhaps even the commit history. If it really is already ported, file a Fedora bug!
Otherwise, check if someone is working on porting it, or if it is perhaps planned. If there is an issue / bug tracker try finding if someone opened a ticket for porting to Python 3. If not, open one yourself! If you find no issue / bug tracker, you can use plain old email. Offer your help with porting the software and await a response. If you want to be proactive, you can start porting and then offer a pull request, but beware in some cases it might not be accepted.
It may happen that you find the upstream is dead and the project orphaned. You can take the initiative and take over the project. Start a new repository on GitLab/GitHub/Bitbucket/what-have-you, copy the sources there and get to work!


This topic provides information on setting up a proxy, and using the Pack200 tool for your Java applications.
This topic includes the following sections:
For enterprise customers it is important to be able to set up secure computing environments within their companies, and proxy configuration is an essential part of doing that. Proxy configuration acts as a security barrier; it ensures that the proxy server monitors all traffic between the Internet and the intranet.
Proxy configuration is normally an integral part of security enforcement in corporate firewalls within intranets. Enterprise customers who want to use Java Plug-in to deploy applets, or Java Web Start to run applications on their intranet web pages can also set up proxy support. This support is required for Java Plug-in and Java Web Start to work in an intranet environment and can be set up through the Java Control Panel.
The Java Control Panel provides four proxy options through the Network Setting dialog, which is accessed by clicking Network Settings in the General tab:
Use browser settings
Use proxy server
Use automatic proxy configuration script
Direct connection
If Use browser settings is selected, then proxy information is obtained entirely through the browser. To change proxy information, see the documentation for your browser:
Internet Explorer:
Change proxy settings in Internet Explorer (Windows Vista, Windows 7, Windows 8)
Configure Proxy Settings for Internet Explorer (Windows Server 2008 R2)
Firefox: Change proxy settings in the Options window - Advanced panel
Chrome: Chrome uses the same connection and proxy settings as Windows; follow the same steps as you would with Internet Explorer
If you select Use proxy server in the Java Control Panel, you have two choices:
Set the Address and the Port for a proxy server with the option to bypass it for local addresses.
Individually set the proxy server for HTTP, Secure, FTP, and Socks connections. You can also provide a list of addresses for which you do not want to use a proxy server.
If you select Use automatic proxy configuration script, then you must enter the URL for the location of the JavaScript method called FindProxyForURL(URL url)
that returns the proxy server to be used for a URL. Support for this script is the same as described in Section 30.1.4, "Automatic Proxy Configuration."
Because browsers on different platforms store proxy information differently, there is no generic mechanism to obtain proxy information. Here is how proxy information is obtained from Internet Explorer and Firefox on Windows:
Internet Explorer: Internet Explorer obtains proxy information from the same set of keys in the Windows registry. Java Plug-in and Java Web Start extract this information directly from the registry.
Firefox: Firefox stores proxy information in a preference file under the user profile directory on the local machine. Firefox also has public APIs available for determining proxy information. Java Plug-in uses these public APIs to obtain the proxy information; Java Web Start obtains the proxy information through reading and parsing the preference file.
Java Plug-in and Java Web Start obtain proxy information at startup time. If you change the proxy settings after Java Plug-in or Java Web Start have started, you may force reloading of the proxy information from the browser through the p option in the Java Console. Java Web Start is restarted for each application, so new proxy information will be used automatically on subsequent launches.
Internet Explorer, Firefox, and Chrome support manual proxy configuration. Users can specify the proxy server and port for each protocol. Users can also specify one proxy server and port for all protocols. To minimize the workload of the proxy server, some sites might bypass the proxy server completely when a machine is connecting to another machine inside the intranet environment. To do this, network administrators and users can specify a proxy server bypass list in the browser's proxy setting.
Internet Explorer: Java Plug-in and Java Web Start recognize and supports the proxy server and port setting associated with the protocol. IE supports various syntaxes in the proxy server bypass list, as follows:
IP address/host name only
IP address/host name with wildcard
IP address/host name with protocol
For example, if you specify "<IP_ADDRESS>;*.eng;http://*.com
" in the proxy server bypass list, then the browser bypasses the proxy whenever one of the following occurs:
"<IP_ADDRESS>" is requested
the URL host name ends with .eng
the URL protocol is HTTP
and the URL host name ends with .com
Currently Java Plug-in and Java Web Start support the first two syntaxes in the proxy server bypass list in IE. IE also supports bypassing the proxy server for local (intranet) addresses without using the proxy server bypass list. Java Plug-in and Java Web Start support this option by bypassing the proxy server if the URL host name contains no dot (.).
Firefox: Java Plug-in and Java Web Start recognize and supports the proxy server and port setting associated with the protocol. For example, if you specify .eng,.sun.com
in the proxy server bypass list in Firefox, it bypasses the proxy whenever the URL hostname ends with .eng
or .sun.com
. Java Plug-in and Java Web Start fully support this syntax in the proxy server bypass list in Firefox.
For more information about manual proxy configuration in your browser, consult the user guide for your browser.
Automatic proxy configuration is supported in the browser by setting a particular URL that contains a JavaScript file with .pac
or .js
extension. This file contains a function called FindProxyForURL
that contains the logic to determine which proxy server to use when the browser receives a connection request. This function is written by the system administrator for the particular intranet environment. When the browser starts up, it recognizes the URL of the JavaScript file and downloads the file to the local machine using direct connection. Then whenever it needs to make a new connection, the browser executes the JavaScript function FindProxyForURL
in the file to obtain the proxy information to set up the connection.
Java Plug-in
Internet Explorer: During startup, Java Plug-in downloads the JavaScript file to the local machine using direct connection. Then whenever it needs to make a new connection, it executes the FindProxyForURL
function to obtain the proxy information using the JavaScript engine in Internet Explorer.
Firefox: During startup, Java Plug-in downloads the JavaScript file to the local machine using direct connection. Then whenever it needs to make a new connection, it executes the FindProxyForURL
function to obtain the proxy information by using the JavaScript engine in Firefox.
Java Web Start
Windows: During startup, Java Web Start downloads the JavaScript file to the local machine using direct connection. Then whenever it needs to make a new connection, it executes the FindProxyForURL function to obtain the proxy information using the JavaScript engine in Internet Explorer.
Linux, Solaris, OS X: During startup, Java Web Start downloads the JavaScript file to the local machine using direct connection. Then whenever it needs to make a new connection, it will parse the FindProxyForURL
function and try its best guess to obtain the proxy information.
Notes on FindProxyForURL
Given a JavaScript engine, the following is applicable to Java Plug-in on all platforms and to Java Web Start on Windows only.
There are a number of JavaScript helper functions which can be called from the JavaScript function FindProxyForURL
. Java Plug-in and Java Web Start provide their own implementations of these functions to completely emulate automatic proxy configuration. Regarding the implementation of these helper function, note the following:
Function dnsResolve
always returns an empty string if the host is not an IP address.
Function isResolvable
always returns false if the host is not an IP address.
Function isInNet
always returns false if the host is not an IP address.
Executing the function FindProxyForURL
always returns proxy information as a string. Java Plug-in and Java Web Start extract the setting in the following way:
If DIRECT
is in the string, Java Plug-in and Java Web Start assume direct connection.
If PROXY
is in the string, they use the first proxy setting for the connection.
If SOCKS
is in the string, they use the SOCKS v4 for the connection.
Otherwise, the proxy information in the string is incorrect. In this case, Java Plug-in and Java Web Start assume direct connection.
Developers sometimes might need to determine the proxy configuration of a given host. By knowing the proxy configuration, they can write more intelligent code to connect to the host through the proper proxy server. The java.net.ProxySelector
class provides configuration support. Here is a simple code example:
When the Java system property jnlp.packEnabled
is set to true
in a JNLP file or an applet tag, Java Plug-in or Java Web Start downloads the JAR file compressed by the Pack200 tool. If the compressed version is not available, Java Plug-in or Java Web Start looks for the uncompressed version.
|
Note: Pack200 compressed JAR files must have the extensionpack.gz . For example, if your JAR file is named sampleApp.jar , then the Pack200 compressed version of this file must be named sampleApp.jar.pack.gz . |
Use the property tag to specify jnlp.packEnabled
to true
within the resources tags, for example:
<jnlp ...> ... <resources> <property name="jnlp.packEnabled" value="true"/> <java version="1.7+" href="http://http://java.sun.com/products/autodl/j2se"/> <jar href="sampleApp.jar" main="true" download="eager"/> </resources> ... </jnlp>
In this example, Java Web Start and the Java Plug-in first look for sampleApp.jar.pack.gz
. If the file is not found, they look for the original, sampleApp.jar
.
Pass the -Djnlp.packEnabled
VM argument by using java_arguments
, for example:
<HTML> ... <APPLET CODE="HelloWorld.class" WIDTH=150 HEIGHT=25> <PARAM NAME = "cache_archive" VALUE = "HelloWorld.jar"/> <PARAM NAME="java_arguments" VALUE="-Djnlp.packEnabled=true"/> </APPLET> ... </HTML>
The Java Plug-in looks for HelloWorld.jar.pack.gz
; if this file is not available, it looks for HelloWorld.jar
.
To increase server and network availability and bandwidth, two compression formats are available to Java deployment of applications and applets: gzip and Pack200. With both techniques, the compressed JAR files are transmitted over the network and the receiving application uncompresses and restores them.
See Reducing the Download Time in the Java Tutorials to create and deploy a compressed JAR file for a rich Internet application.
The following sections describes the technical details of how a web server handles a compressed JAR file.
Hypertext Transfer Protocol -- HTTP 1.1 (RFC 2616) discusses HTTP compression. HTTP Compression allows applications JAR files to be deployed as compressed JAR files. The supported compression techniques are gzip, compress, and deflate.
As of JDK version 5.0, HTTP compression is implemented in Java Web Start and Java Plug-in in compliance with RFC 2616. The supported techniques are gzip and pack200-gzip.
The requesting application can send an HTTP request to the server indicating its ability to handle compressed versions of the file. The following example shows the HTTP request created when the Dynamic Tree Demo applet, whose JAR file has been compressed with Pack200, is loaded:
Example 30-2 Sample HTTP Request
GET http://www.example.com/DynamicTreeDemo.jar.pack.gz HTTP/1.1 accept-encoding: pack200-gzip,gzip User-Agent: Mozilla/4.0 (Windows 7 6.1) Java/1.8.0 Host: example.com Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive
The following examples shows the HTTP response from the server:
Example 30-3 Sample HTTP Response
HTTP/1.1 200 OK Date: Wed, 21 Mar 2012 20:13:22 GMT Server: Apache/2.2.11 (Solaris, Linux, or OS X) mod_ssl/2.2.11 OpenSSL/0.9.8k SVN/1.6.2 DAV/2 Last-Modified: Thu, 08 Mar 2012 03:48:34 GMT ETag: "489ee5-112d-4bab326774e43" Accept-Ranges: bytes Content-Length: 4397 Keep-Alive: timeout=5, max=99 Connection: Keep-Alive Content-Type: application/x-gzip Content-Encoding: gzip

The Accept-Encoding
field specifies what the client can accept, which is set by the client. The Content-Encoding
field indicates what is being sent, which is set by the server. The Content-Type
field indicates what the client should expect when the transformation or decoding is done.
In this example, the Accept-Encoding
field is set to pack200-gzip
and gzip
, indicating to the server that the application (in this case, Mozilla Firefox running in Windows 7 with the Java Plug-in that comes with JRE 7) can handle pack200-gzip
and gzip
formats.
The server searches for the requested JAR file with a .pack.gz
or .gz
file extension and responds with the located file. The server sets the response header Content-Encoding
field to pack200-gzip
, gzip
, or NULL
depending on the type of file that is being sent, and optionally may set the Content-Type
to application/x-java-archive
. Therefore, by inspecting the Content-Encoding
field, the requesting application can apply the corresponding transformation to restore the original JAR file.
Figure 30-1 Packed or Compressed JAR Returned
In Figure 30-1, the client requests the file foo.jar
with the Accept-Encoding
field pack200-gzip,gzip
. The server searches for the file foo.jar.pack.gz
. If the server finds the file, it sends the file to the client and sets the Content-Encoding
field to pack200-gzip
.
Figure 30-2 Packed or Compressed JAR File Not Found
In Figure 30-2, if the file foo.jar.pack.gz
is not found, the server responds with the file foo.jar.gz
, if it is found, and sets the Content-Encoding
field to gzip
.
Figure 30-3 Packed or Compressed JAR FIle and Standard gzip File Not Found
In Figure 30-3, if the files foo.jar.pack.gz
and foo.jar.gz
are not found, then the server responds with the file foo.jar
and either does not set the Content-Encoding
field or sets it to NULL
.
Figure 30-4 Legacy Application Requesting JAR File
In Figure 30-4, a legacy application (an application without HTTP or Pack200 compressions) requests the file foo.jar
; consequently this application will continue to work seamlessly. Therefore, it is recommended that you host all three files foo.jar
, foo.jar.gz
, and foo.jar.jar.gz
.
gzip
is a freely available compressor available within the JRE and the SDK as java.util.zip.GZIPInputStream
and java.util.zip.GZIPOutputStream
.
The command line versions are available with most Solaris, Linux, or OS X operating systems, Windows UNIX toolkits (Cygwin and MKS Toolkit), or from http://www.gzip.org/
.
You can get the highest degree of compression using gzip
to compress an uncompressed JAR file versus compressing a compressed JAR file. The downside is that the JAR file may be stored uncompressed on target systems.
For example, the following table shows the results of using gzip
to compress the Notepad.jar
file.
| Type of JAR File | Size Before Compression with gzip | Size After Compression with gzip |
|---|---|---|
| JAR file that contains individual deflated entries | Notepad.jar : 46.25 KB |
Notepad.jar.gz : 43.00 KB |
| JAR file that contains stored entries, which are not compressed | Notepad.jar : 987.47 KB |
Notepad.jar.gz : 32.47 KB |
As you can see, the download size can be reduced by 14% by compressing an uncompressed JAR file compared to 3% by compressing a compressed JAR file.
Pack200 compresses large files very efficiently, depending on the density and size of the class files in the JAR file. You can expect compression to one-ninth the size of the JAR file if it contains only class files and is in the order of several megabytes.
Using the same JAR file in the previous example:
Notepad.jar
: 46.25 kb
Notepad.jar.pack.gz
: 22.58 kb
In this case, the same JAR file can be reduced by 50%.
Pack200 works most efficiently on Java class files. It uses several techniques to efficiently reduce the size of JAR files:
Merges and sorts the constant-pool data in the class files and co-locates them in the archive.
Removes redundant class attributes.
Stores internal data structures.
Uses delta and variable length encoding.
Chooses optimum coding types for secondary compression.
Compress and uncompress JAR files with the command line interfaces pack200
and unpack200
in the bin
directory of your SDK or JRE directory.
You can also programmatically invoke Pack200 interfaces; see java.util.jar.Pack200
.
Consider the size of the JAR file, the contents of the JAR file, and the bandwidth of your target audience.
All these factors play into choosing a compression technique. The unpack200
tool is designed to be as efficient as possible, and it takes little time to restore the original file. If you have large JAR files (2 MB or more) comprised mostly of class files, Pack200 is the preferred compression technique. If you have large JAR files which are comprised of resource files (JPEG, GIF, data, etc.), then gzip is the preferred compression technique.
Specify the segment limit for Pack200 compression.
Pack200 loads the entire compressed file into memory. However, when target systems are memory and resource constrained, setting the Pack200.Packer.SEGMENT_LIMIT
to a lower value will reduce the memory requirements during compression and uncompression.
As a special case, a value of -1
will produce a single large segment with all input files, while a value of 0
will produce one segment for each class. Larger archive segments result in less fragmentation and better compression, but processing them requires more memory.
The default is -1
, which means pack200
will always create a single segment output file. In cases where extremely large output files are generated, you are are strongly encouraged to use segmenting or break up the input file into smaller JARs.
For example, a 10 MB JAR packed without this limit will typically pack about 10% smaller, but pack200
may require a larger Java heap (about ten times the segment limit).
Sign the JAR files.
Pack200 rearranges the contents of the resulting JAR file. The jarsigner
tool hashes the contents of the class file and stores the hash in an encrypted digest in the manifest. When unpack200
uncompresses a file, the contents of the classes will be rearranged and thus invalidate the signature. Therefore, the JAR file must be normalized first using pack200
and unpack200
, and thereafter signed.
Here's why this works: Any reordering pack200
does on any class file structures is idempotent, so the second time it is compressed, it does not change the orderings produced by the first compression. Also, unpack200
is guaranteed by the JSR 200 specification to produce a specific bytewise image for any given transmission ordering of archive elements.
For example, suppose you want to use HelloWorld.jar
:
Recompress, or repack, the file to normalize the JAR file; repacking uncompresses and compresses the JAR file in one step.
% pack200 --repack HelloWorld.jar
Sign the JAR.
% jarsigner -keystore myKeystore HelloWorld.jar user_name
|
Note: You must sign the repacked file with the same key that was used when building the original JAR file. Alternatively, delete all signature files found in theMETA-INF directory before repacking, re-signing and verifying. The signature files are named MANIFEST.MF , *.DSA and *.SF . |
Verify the just signed JAR file to ensure the signing worked.
% jarsigner -verify HelloWorld.jar jar verified.
Ensure the JAR file still works.
% Java -jar HelloWorld.jar HelloWorld
Compress the JAR file with pack200
.
% pack200 HelloWorld.jar.pack.gz HelloWorld.jar
|
Note: You must compress the JAR file with the same options that you used to repack the file to normalize the JAR file, as demonstrated in Step a. Additionally, you must set the segment limit to-1 (unlimited) for all packing steps when using JDK 6 and earlier releases to prevent accidental variations of segment boundaries; class file sizes can change slightly under these circumstances, thus disrupting signatures. The default segment limit for JDK 7 and later is -1 . |
Uncompress the file with unpack200
% unpack200 HelloWorld.jar.pack.gz HelloT1.jar
Verify the JAR file.
% jarsigner -verify HelloT1.jar jar verified.
Test the JAR file.
% Java -jar HelloT1.jar HelloWorld
After verification, you can deploy the compressed pack file HelloWorld.jar.pack.gz
.
Apply reduction techniques.
Pack200 by default behaves in a High Fidelity (Hi-Fi) mode, meaning all the original attributes present in the classes as well as the attributes of each individual entry in a JAR file is retained. These typically tend to add to the packed file size. Use the following techniques to further reduce the size of the download:
Modification times: If modification time of the individual entries in a JAR file is not a concern, specify the option Pack200.Packer.MODIFICATION_TIME="LATEST"
. This will allow one modification time to be transmitted in the pack file for each segment. The latest time will be the latest time of any entry within that segment.
Deflation hint: Similar to setting the modification time to "LATEST"
, if the compression state of the individual entries in the archive is not required, set Pack200.Packer.DEFLATION_HINT="false"
. This will fractionally reduce the download size, as individual compression hints will not be transmitted. However, the JAR file when recomposed will contain "stored" entries and hence may consume more disk space on the target system.
For example:
pack200 --modification-time=latest --deflate-hint="true" tools-md.jar.pack.gz tools.jar
|
Note: The above optimizations will yield better results with a JAR file containing thousands of entries. |
Attributes: Several class attributes are not required when deploying JAR files. These attributes can be stripped out of class files, significantly reducing download size. However, care must be taken to ensure that required runtime attributes are maintained.
Debugging attributes: If debugging information, such as Line Numbers and Source File, is not required (typically in applications stack traces), then these attributes can be discarded by specifying Pack200.Packer.STRIP_DEBUG=true.
This typically reduces the packed file by about 10%.
Example:
pack200 --strip-debug tools-stripped.jar.pack.gz tools.jar
Other attributes: Advanced users can use some of the other strip-related properties to strip out additional attributes. However, extreme caution should be used when doing so, the resultant JAR file must be tested on all possible Java runtime systems to ensure that the runtime does not depend on the stripped attributes.
Handle unknown attributes.
Pack200 deals with standard attributes defined by the Java Virtual Machine Specification; however compilers are free to introduce custom attributes. When such attributes are present, by default, Pack200 passes through the class, emitting a warning message. These "passed-through" class files may contribute to bloating of packed files. If the unknown attributes are prevalent in the classes of a JAR file, this may lead to a very large bloat in the compressed output. In such cases, consider the following strategies:
Strip the attribute if the attribute is deemed to be redundant at runtime; this can be achieved by setting the property Pack200.Packer.UNKNOWN_ATTRIBUTE=STRIP
:
pack200 --unknown-attribute=strip foo.pack.gz foo.jar
If the attributes are required at runtime, and they do contribute to inflation in the size of the compressed file, then identify the attribute from the warning message and apply a suitable layout for these as described in the Pack200 JSR 200 specification, and the Java API reference section for the interface Pack200.Packer.
It is possible that a compiler could define an attribute not implemented in the layout specification of Pack200, and may cause the pack200
to malfunction. In such cases, an entire class file or class files can be "passed through", as if it were a resource by virtue of its name and can be specified as follows:
pack200 --pass-file="com/acme/foo/bar/baz.class" foo.pack.gz foo.jar
The following passes through an entire directory and its contents,
pack200 --pass-file="com/acme/foo/bar/" foo.pack.gz foo.jar
|
Note: When signing large JAR files, this step might fail with a security error. A likely cause is bug 5078608. Use one of the following workarounds:
|
Take advantage of Pack200 in your installation program.
You may wish to take advantage of the Pack200 technology in your installation program, whereby a product's JAR files may need to compressed using Pack200 and uncompressed during installation. If the JRE or SDK is bundled in the installation, you are free to use the unpack200
(Solaris, Linux, or OS X) or unpack200.exe
(Windows) tool in the distribution bin
directory. This implementation is a pure C++ application requiring no Java runtime to be present for it to run.
Windows: Installers may use a better algorithm than the one in GZIP to compress entries. In such cases, one will get better compression using the Installer's intrinsic compression, by using the pack200
tool as follows:
pack200 --no-gzip foo.jar.pack foo.jar
This will prevent the output file from being gzip compressed.
unpack200
is a Windows console application; i.e. it will display a MS-DOS window during the install. To suppress this, use a launcher with a WinMain
, which will suppress this window, as shown below.
Sample Code:
#include "windows.h" #include <stdio.h> int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { STARTUPINFO si; memset(&si, 0, sizeof(si)); si.cb = sizeof(si); PROCESS_INFORMATION pi; memset(&pi, 0, sizeof(pi)); //Test //lpCmdLine = "c:/build/windows-i586/bin/unpack200 -l c:/Temp/log c:/Temp/rt.pack c:/Temp/rt.jar"; int ret = CreateProcess(NULL, /* Exec. name */ lpCmdLine, /* cmd line */ NULL, /* proc. sec. attr. */ NULL, /* thread sec. attr */ TRUE, /* inherit file handle */ CREATE_NO_WINDOW | DETACHED_PROCESS, /* detach the process/suppress console */ NULL, /* env block */ NULL, /* inherit cwd */ &si, /* startup info */ &pi); /* process info */ if ( ret == 0) ExitProcess(255); // Wait until child process exits. WaitForSingleObject( pi.hProcess, INFINITE ); DWORD exit_val; // Be conservative and return if (GetExitCodeProcess(pi.hProcess, &exit_val) == 0) ExitProcess(255); ExitProcess(exit_val); // Return the error code of the child process return -1; }
It is required that all JAR files, compressed and uncompressed, be tested for correctness with your applications test qualifiers. When using the command line interface pack200
, the output file will be compressed using gzip with default values. A user may create a simple pack file and compress using gzip
with user-specified options or using some other compressor.
In Java SE 8, the Java class file format has been updated because of JSR 292, Java Virtual Machine Support for Non-Java Languages. Consequently, the Pack200 engine has been updated accordingly to ensure that Java SE 8 class files are compressed effectively. In particular, the Pack200 engine now recognizes constant pool entries and new bytecodes introduced by JSR 292.
Pack200 has been updated to support the following, JSR-308 (Type Annotations) and JSR 335 (Lambda Expressions for the Java TM Programming Language)


eBay Puts Another Nail in the Password Coffin with WebAuthn Rollout
81% of all hacking-related breaches start with stolen or weak passwords…
eBay has become the latest company to move towards phasing out passwords, adding WebAuthn-based logins to its web-based version of the ecommerce platform; which has over 183 million registered buyers.
With adoption of the emerging security standard, the company is also one of the first major ecommerce platform to enable biometric authentication as a first factor authentication on web browsers.
Supported devices include Android phones with biometrics enabled using the Chrome browser version 75 and higher, eBay said in a developer blog, saying it plans to expand to more platforms in the future.
What is WebAuthn?
WebAuthn is an emerging standard written by the W3C and FIDO that replaces passwords with an that API allows servers to register and authenticate users using public key cryptography instead of a password.
The specification was created with the participation of Google, Mozilla, Microsoft, Yubico, and others. As of September 2018, there is support for WebAuthn in the stable builds of Chrome, Firefox and Edge.
Users can deploy a fob like a YubiKey to log into their online accounts without typing a password, or use biometrics.
(eBay already offered the feature on its mobile application ).
With an estimated 81 percent of all hacking-related breaches starting with stolen or weak passwords and the brute-forcing of passwords ever easier, consensus is growing that passwords as an authentication factor (certainly as a primary one) are a security risk for both businesses and consumers.
Security specialists that while various aspects of WebAuthn continue to be enhanced, the credential API is not expected to change much and now is as good a time as any to develop WebAuthn applications.
For businesses/developers working on their own code, the FIDO Alliance has been developing conformance tools for testing FIDO2 operability, so production-ready implementations of WebAuthn/FIDO2 architecture can be put to the test.

| ipump | 1 | Option to suppress calculations of drawdown at pumped well: IPUMP = 0: Drawdown is not calculated at pumped well. IPUMP = 1: Drawdown is calculated at pumped well. |
| irun | 1 | Option to suppress drawdown calculations for the pumped well. Allows user to specify time-drawdown data, but those data are ignored during the simulation. Options are: IRUN = 0: Drawdowns not calculated. IRUN = 1: Drawdowns calculated. |
| Parameter | Default value | Description |
|---|---|---|
| obname | “obs1” | Name of observation well or piezometer; up to 10 characters in length. |
| r | 30.0 | Radial distance from axis of pumped well to observation well or piezometer, in units of length. |
| iows | 0 | Type of observation well or piezometer: IOWS = 0: Partially penetrating observation well. IOWS = 1: Fully penetrating observation well. IOWS = 2: Observation piezometer. |
| idpr | 0 | Options for delayed response of observation well. IDPR = 0: No delayed response. IDPR = 1: Delayed response. |
| rp | ifelse(idpr == 0, 0, 0.1) | Inside radius of the observation well (or piezometer) standpipe in the interval over which water levels are changing during pumping, in units of length. Enter 0 if IDPR = 0. |
| z1 | ifelse(iows == 2, 0, 5.0) | Depth below top of aquifer or initial water table to the top of screened interval of observation well, in units of length. Use for IOWS = 0 or 1. Enter 0 if IOWS = 2. |
| z2 | ifelse(iows == 2, 0, 10.0) | Depth below top of aquifer or initial water table to the bottom of screened interval of observation well, in units of length. Use for IOWS = 0 or 1. Enter 0 if IOWS = 2. |
| xll | ifelse(idpr == 0, 0, z2 - z1) | Length of screened interval of observation well or piezometer, in units of length. Enter 0 if IDPR = 0. |
| zp | ifelse(iows == 2, 3.0, 0.0) | Depth below top of aquifer or initial water table to center of piezometer in units of length. Use for IOWS = 2. Enter 0.0D0 if IOWS = 0 or 1. |
| tsobs | data.frame(t = 60 * 1:3, dd = c(0.4, 0.6, 0.7)) | data.frame with column containing the user-specified times for which drawdown at the observation well or piezometer will be calculated. If the data.frame has no rows, no drawdowns are calculated for the observation well or piezometer. The data.frame can (optionally) contain the measured drawdown for the observation well or piezometer at the corresponding times in an additional column . |
| irun | 1 | Option to suppress drawdown calculations for the observation well or piezometer. Allows user to specify time-drawdown data, but those data are ignored during the simulation. Options are: IRUN = 0: Drawdowns not calculated. IRUN = 1: Drawdowns calculated. |
