String Operators¶
The +
Operator¶
The + operator concatenates strings. It returns a string consisting of the operands joined together.
s1 = "Ub"
s2 = "er"
s1+s2
'Uber'
s3 = "Fizz"
s4 = "Buzz"
s3+s4
'FizzBuzz'
The *
Operator¶
The * operator creates multiple copies of a string. If s
is a string and n
is an integer, either of the following expressions returns a string consisting of n
concatenated copies of s
\(s \times n\)
\(n \times s\)
s = "Fizz"
n = 3
# n * s
s * n
'FizzFizzFizz'
# s * n
n * s
'FizzFizzFizz'
Note
The multiplier operand n must be an integer. You’d think it would be required to be a positive integer, but amusingly, it can be zero or negative, in which case the result is an empty string.
"foo" * -8
''
"foo" * .5
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-7-cbe9236f5c54> in <module>
----> 1 "foo" * .5
TypeError: can't multiply sequence by non-int of type 'float'
The in
Operator¶
Python also provides a membership operator that can be used with strings. The in operator returns True if the first operand is contained within the second, and False otherwise
text = "I love Bangladesh!"
# membership check
"love" in text
True
# Dhaka in text?
"Dhaka" in text
False
# Dhaka not in text?
"Dhaka" not in text
True
Built-in String Function¶
ord(c)
¶
Returns an integer of the given character.
# ASCII value of a
ord('a')
97
# ASCII value of A
ord('A')
65
# ASCII value of #
ord("#")

chr(i)
¶
Converts an integer to character
# Convert integer to character 97 == a
chr(97)

str(param)
¶
Returns a string representation of a string
# 10 into '10'
str(10)
'10'
# 10.5 into '10.5'
str(10.5)
'10.5'
String Indexing¶
In Python, strings are ordered sequences of character data, and thus can be indexed in this way. Individual characters in a string can be accessed by specifying the string name followed by a number in square brackets ([]). String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on. The index of the last character will be the length of the string minus one.
# forward indexing
country = "Bangladesh"
# check length
len(country)
10
country[0]
'B'
country[1]
'a'
country[2]

Voronoi treemaps are an alternative to traditional rectangular treemaps for visualizing hierarchical data. Like rectangular treemaps, Voronoi treemaps represent hierarchical data by dividing the canvas region into cells for each node at the top of the hierarchy, and then further dividing each of these cells for the children of those nodes. The organic shapes created by the Voronoi treemap can be easier to distinguish sibling nodes from nodes in other branches of the hierarchy. Voronoi treemaps can also be fit to non-rectangular canvases, and are often more aesthetically pleasing.
We implemented the fastest known version in javascript and gave it a D3 API so you can incorporate it into your favorite D3 application. Use d3.layout.voronoitreemap() the same way you would any other d3.layout for hierarchical data. If your dataset is deeper than three or four levels it is recommended you set a maximum depth as the Voronoi treemap computations can get pretty heavy.
A demo of our software is available here. The page source for this demo also demonstrates the use of our software.

Placement policies are implemented as a memory allocation strategy, to help determine where in main memory should incoming processes be placed.
In non-paged systems, placement policy must maintain a list of the locations and sizes of all unallocated parts of memory (free list). Then, it is decided which free memory should be used, and update the free list after each insertion
The main memory is scanned for the first chunk of memory in the free list that is big enough to accommodate the requesting process.
The chunk of memory in the free list which produce the smallest left-over is chosen to be allocated to the process.
In worst fit approach is to locate largest available free memory partition so that such portion will produce the most left-over memory space. It is the reverse of best fit.

--- blog: true layout: page author: Julius Chrobak title: New Built In Functions date: 2012 12 20 ---
The latest version of Bandicoot language (still in development) comes with two new built in functions. Normally, I would not consider this to be important enough to write a blog about it but this time it is different. Those two functions are the first built in Bandicoot functions developers can use in primitive expressions, and more are coming. So stay tuned!
In order to support various built in functions in the future we decided to use a simple concept of packages to group them together according to their meaning and not to overload the user's namespace.
There are two packages available right now:
The Time package groups together all functions related to time manipulation. The list of functions implemented is short:
The String package groups together all functions which help to manipulate string attributes. This list is also very short:
Let's imagine we have a set of orders with an attribute called "created" which captures the time stamp when an order was created. There are two simple examples which come to my mind immediately and nicely demonstrate the use of the Time.Now function:
var orders {id int, user string, created long}; # extend the input with the current time fn StoreOrder(in {id int, user string}) void { orders += extend (created = Time.Now) in; } # returns order ids of the recent orders only (not older than 1 hour) fn Recent() {id int} { return select (created > Time.Now - 3600L * 1000L) orders; }
The String.Index function is also straightforward so I am going to put down only one example. It finds out the first occurrence of a word in each sentence from the input set in one go:
fn GetIndex(sentences {value string}, s string) {value string, idx int} { return extend (idx = (String.Index value s)) sentences; }
$ cat sentences.csv value Hello World! This world is great. Isn't it? $ curl --data-binary @sentences.csv 'http://localhost:12345/GetIndex?s=world' idx,value 5,This world is great. Isn't it? -1,Hello World!
Checkout the latest code from the master branch and give it a try!
In the near future you can expect more functions to be built. Feel free to raise a github issue or drop me an email (julius at bandilab dot org) if you have any suggestions or ideas on what the next batch of functions added to the language should be.

Trail Blitz Photographs
----
Intro
For a booklet assignment I was tasked with taking photographs based on California Bay Area cities' greenspaces for a "travel company" called Trail Blitz. The photos would be laid out on a eight page booklet spread, highlighting three greenspaces, and would encourage people to visit these places.
Greenspace
Greenspace is a place that is usually undeveloped open space; for example: parks.
Inspiration
When taking these photos I decided to take some close up shots to showcase the beauty of even the smallest details that exist in nature. Such as the unique ridges in the tree's bark. The other photographs I took were of the "big picture" with nearly everything in the frame.

Climate Change Indicators: Antarctic Sea Ice
Key Points
- Antarctic sea ice extent in September and February has increased somewhat over time, although the most recent year was below average. The September maximum extent reached the highest level on record in 2014—about 7 percent larger than the 1981–2010 average—but in 2015 it was slightly below the 1981–2010 average. As for February extent, 2013, 2014, and 2015 were three of the six largest years on record, but extent in 2016 was about 9 percent below the 1981–2010 average (see Figure 1).
- Slight increases in Antarctic sea ice are outweighed by the loss of sea ice in the Arctic during the same time period (see the Arctic Sea Ice indicator). Overall, the Earth has lost sea ice at an average rate of 13,500 square miles per year since 1979—equivalent to losing an area larger than the state of Maryland every year.3 This decrease affects the Earth’s energy balance.
Background
The Southern Ocean around Antarctica freezes to form sea ice every year. This sea ice reaches its maximum extent in September or early October, around the end of winter in the Southern Hemisphere. At that point, virtually the entire continent of Antarctica is surrounded by a ring of sea ice (see images below). The ice melts in the summer months (December to February) because of warmer temperatures and long hours of sunlight. Unlike the Arctic, where a large area of sea ice lasts year-round (see the Arctic Sea Ice indicator), the sea ice around Antarctica is thinner and nearly all of it melts in a typical summer. This happens because no landmass is present to stop Antarctic sea ice from breaking up and drifting northward into warmer waters, where it eventually melts.
Like Arctic sea ice, Antarctic sea ice affects global climate, regional climate, and ecosystems. Because ice is more reflective than liquid water, it plays a significant role in maintaining the Earth’s energy balance and helping to keep polar regions cool. (For more information on how the color of the Earth's surface affects the absorption of sunlight, see the Snow Cover indicator.) Sea ice also keeps the air cool by forming a barrier between the cold air above and the warmer water below. Antarctic sea ice is an important part of the habitat for penguins, seals, and other animals.
Warmer air and ocean temperatures are generally expected to reduce the amount of sea ice present worldwide. While warming has already driven a noticeable decline in sea ice in the Arctic, extent in the Antarctic as a whole has not yet declined (and has actually increased slightly), which may reflect influences of wind patterns, ocean currents, and precipitation around the continent.1
About the Indicator
Figure 1 shows Antarctic sea ice extent from 1979, when routine monitoring by satellites started, to early 2016. Sea ice extent is defined as the area of ocean where at least 15 percent of the surface is frozen. This threshold was chosen because scientists have found that it gives the best approximation of the edge of the ice. Data are collected throughout the year, but for comparison, this indicator focuses on the months when sea ice typically reaches its minimum and maximum extent. February is typically when the sea ice extent reaches its annual minimum after melting during the spring and summer. The ice typically reaches its maximum extent in late September or early October after winter freezing, with the largest monthly average extent occurring in September. Data for this indicator were gathered by the National Snow and Ice Data Center using satellite imaging technology and data processing methods developed by the National Aeronautics and Space Administration.
Unlike EPA’s Arctic Sea Ice indicator, this indicator does not show the age of Antarctic sea ice. This is because nearly all of the Antarctic ice melts every summer, unlike the Arctic, where a large portion of ice survives for multiple years.2
Indicator Notes
Compared with the noticeable decrease in Arctic sea ice extent (see the Arctic Sea Ice indicator), the increase in Antarctic sea ice is small. Many factors appear to be influencing Antarctic sea ice extent, including changes in wind patterns, currents, and precipitation.6 Without better ice thickness and ice volume estimates, it is difficult to characterize how the total amount of Antarctic sea ice is responding to climate change.7
Data Sources
The data for this indicator were provided by the National Snow and Ice Data Center. These data are also available online at: http://nsidc.org/data/seaice_index/archives.html. The National Snow and Ice Data Center produces a variety of reports analyzing sea ice data.

| pgpool-II 4.0.3 Documentation | |||
|---|---|---|---|
| Prev | Up | Chapter 5. Server Configuration | Next |
Pgpool-II can synchronize database nodes and attach a node without stopping the service. This feature is called "online recovery". Online recovery can be executed by using pcp_recovery_node command.
For online recovery, the recovery target node must be in detached state. This means the node must be either manually detached by pcp_detach_node or automatically detached by Pgpool-II as a consequnece of failover.
If you wish to add a PostgreSQL server node dynamically, reload the pgpool.conf after adding the backend_hostname and its associated parameters. This will register the new server to Pgpool-II as a detached backend node.
Note: The recovery target PostgreSQL server must not be running for performing the online recovery. If the target PostgreSQL server has already started, you must shut it down before starting the online recovery.
Online recovery is performed in two phases. The first phase is called "first stage" and the second phase is called "second stage". You need to provide scripts for each stage. Only replication_mode requires the second stage. For other modes including streaming replication mode the second stage is not performed and you don't need to provide a script for the stage in recovery_2nd_stage_command. i.e. you can safely leave it as an empty string.
Connections from cliens are not allowd only in the second stage while the data can be updated or retrieved during the first statge.
Pgpool-II performs the follows steps in online recovery:
CHECKPOINT.
Execute first stage of online recovery.
Wait until all client connections have disconnected (only in replication_mode).
CHECKPOINT (only in replication_mode). specified).
Execute second stage of online recovery (only in replication_mode).
Start up postmaster (perform pgpool_remote_start)
Node attach
Note: There is a restriction in the online recovery in replication_mode. If Pgpool-II itself is installed on multiple hosts, online recovery does not work correctly, because Pgpool-II has to stop all the clients during the 2nd stage of online recovery. If there are several Pgpool-II hosts, only one of them will have received the online recovery command and will block the connections from clients.
Specifies the PostgreSQL user name to perform online recovery.
This parameter can be changed by reloading the Pgpool-II configurations.
Specifies the password for the PostgreSQL user name configured in recovery_user to perform online recovery.
If recovery_password is left blank Pgpool-II will first try to get the password for recovery_user from pool_passwd file before using the empty password.
You can also specify AES256-CBC encrypted password in recovery_password field. To specify the AES encrypted password, password string must be prefixed with AES after encrypting (using aes-256-cbc algorithm) and encoding to base64.
To specify the unencrypted clear text password, prefix the password string with TEXT. For example if you want to set mypass as a password, you should specify TEXTmypass in the password field. In the absence of a valid prefix, Pgpool-II will considered the string as a plain text password.
You can also use pg_enc utility to create the correctly formatted AES encrypted password strings.
Note: Pgpool-II will require a valid decryption key at the startup to use the encrypted passwords. see Section 6.4.2 for more details on providing the decryption key to Pgpool-II
This parameter can be changed by reloading the Pgpool-II configurations.
Specifies a command to be run by master (primary) node at the first stage of online recovery. The command file must be placed in the database cluster directory for security reasons. For example, if recovery_1st_stage_command = 'sync-command', then Pgpool-II will look for the command scrit in $PGDATA directory and will try to execute $PGDATA/sync-command.
recovery_1st_stage_command receives following 5 parameters:
Path to the database cluster of the master (primary) node.
Hostname of the backend node to be recovered.
Path to the database cluster of the node to be recovered.
Port number of the master (primary) node (Pgpool-II 3.4 or after).
Node number to be recovered (Pgpool-II 4.0 or after)
Note: Pgpool-II accept connections and queries while recovery_1st_stage command is executed, so you can retrieve and update data.
| Caution |
recovery_1st_stage command runs as a SQL command from PostgreSQL's point of view. So recovery_1st_stage command can get prematuraly killed by PostgreSQL if the PostgreSQL's statement_time_out is configured with the value that is smaller than the time recovery_1st_stage_command takes for completion. Typical error in such case is rsync used in the command is killed by signal 2 for example.
|
This parameter can be changed by reloading the Pgpool-II configurations.
Specifies a command to be run by master node at the second stage of online recovery. This parameter only neccessary for replication_mode. The command file must be placed in the database cluster directory for security reasons. For example, if recovery_2nd_stage_command = 'sync-command', then Pgpool-II will look for the command scrit in $PGDATA directory and will try to execute $PGDATA/sync-command.
recovery_2nd_stage_command receives following 5 parameters:
Path to the database cluster of the master(primary) node.
Hostname of the backend node to be recovered.
Path to the database cluster of the node to be recovered.
Port number of the master (primary) node (Pgpool-II 3.4 or after).
Node number to be recovered (Pgpool-II 4.0 or after)
Note: Pgpool-II does not accept client connections and queries during the execution of recovery_2nd_stage_command command, and waits for the existing clients to close their connections before executing the command. Therefore, the recovery_2nd_stage_command may not execute if the client stays connected for a long time.
| Caution |
recovery_2nd_stage command runs as a SQL command from PostgreSQL's point of view. Therefore, recovery_2nd_stage command can get prematuraly killed by PostgreSQL if the PostgreSQL's statement_time_out is configured with the value that is smaller than the time recovery_2nd_stage_command takes for completion. |
This parameter can be changed by reloading the Pgpool-II configurations.
Specifies the timeout in seconds to cancel the online recovery if it does not completes within this time. Since Pgpool-II does not accepts the connections during the second stage of online recovery, this parameter can be used to cancel the online recovery to manage the service down time during the online recovery.
This parameter can be changed by reloading the Pgpool-II configurations.
Specifies the time in seconds to disconnect a client if it remains idle since the last query during the online recovery. client_idle_limit_in_recovery is similar to the client_idle_limit but only takes effect during the second stage of online recovery.
This is useful for preventing the Pgpool-II recovery from being disturbed by the lazy clients or if the TCP/IP connection between the client and Pgpool-II is accidentally down (a cut cable for instance).
Note: client_idle_limit_in_recovery must be smaller than recovery_timeout. Otherwise, recovery_timeout comes first and you will see following error while executing online recovery:
ERROR: node recovery failed, waiting connection closed in the other pgpools timeout
If set to -1, all clients get immediately disconnected when the second stage of online recovery starts. The default is 0, which turns off the feature.
This parameter can be changed by reloading the Pgpool-II configurations. You can also use PGPOOL SET command to alter the value of this parameter for a current session.


RCE Capital may move higher, says RHB Retail Research
by theedgemarkets.comKUALA LUMPUR (Nov 15): RHB Retail Research said RCE Capital Bhd may move higher after it continued holding above the RM1.62 support.

Hi, I'm Matt Colman and I'm a Front End Developer. My main weapon of choice is javascript. I love javascript! I love lamp. I'm passionate about clever code. Performant, light-weight, readable, extendable. Sometimes there's a compromise, but I always aim to achieve them all.
I choose to be a front end developer because I'm inspired by seeing great design come to life.
I strive to create lag-free, jank-free, 60fps web apps and games. People really notice when something moves beautifully on the web.
I'm canvas obsessed. I've made games in canvas using CreateJS and Phaser. More recently I've been making apps with React. Currently I'm excited by ES6 and functional javascript. Basically if it's javascript...


Supercar Blondie Checks Out The Ludicrous Maybach G650 Landaulet
Rear passengers can enjoy the convertible top.
by Anthony AlanizThe Mercedes-Maybach G650 Landaulet could be the G-Class taken to its most extreme. It takes the already lavish entry-level G-Class and turns it into a flashy limousine for the well-to-do. It's so flashy that if you ponder the possibilities of when you'd be able to use the convertible top, you will quickly understand the definition of finite.
However, this is more than a G-Class with a snazzier interior. The Mercedes-Maybach G650 Landaulet is something else entirely. Thanks to a new video from Supercar Blondie YouTube channel, we can get up close with what makes the G650 Landaulet so luxurious.
Check Out More Cool G-Class Videos:
The video spends most of its time in the rear seats, which is where you'd want to be. Mercedes took them from the S-Class and plopped them into the G650, which Mercedes extended 22.7-inches (579 millimeters) to improve the rear legroom. Rear passengers are also treated to heated and cooled cupholders, reclining rear seats, one 10-inch screen each, and a pair of folding tables.
With great luxury often comes great power, and the G650 is no disappointment. It uses a twin-turbocharged V12 with 630 horsepower (463 kilowatts) and 737 pound-feet (1,000 Newton-meters) of torque. Power routes to all four 22-inch wheels through portal axles borrowed from the G63 6x6 and the G500 4x42. It has 17.7 inches of ground clearance and comes with three differential locks.

It’s a wonderful place to spend time, if someone else is doing the driving, though that’d be fun, too. You can’t lower the convertible on the highway, though enjoying a bit of sun around town could be pleasant.
However, for all its luxuries, the G650 Landaulet isn’t without flaws. There’s no rear backup camera, and visibility out the rear is limited because of the soft top's small rear window, the high-mount brake light, and spare tire. But those are problems for the chauffeur.

Review: Space Cowboys (2000)
Cast: Clint Eastwood, Tommy Lee Jones, Donald Sutherland, James Garner, James Cromwell, Marcia Gay Harden, William Devane, Loren Dean. Writers: Ken Kaufman and Howard Klausner. Director: Clint Eastwood.
Review by Scott Hunt Movie Hunt: http://netdirect.net/~hunt/index.html
Rating: Near Miss (2 out of 4 stars)
Make no mistake about it, Space Cowboys succeeds due to the varying iconic levels of three of its main leads; Eastwood, Jones and Sutherland. Over the years, each man has arguably put a distinctive stamp on American cinema. Dropped into the unsurprising, yet satisfying Space Cowboys, their strength of personality lends the film it's best moments. The script has no real unexpected moments and doesn't seek to blast you with over the top special effects. It's quite simply a fun movie that's as enjoyable as a home cooked meal.
The script pleasingly plays off the respective star's real life and film images with varying degrees of success. Eastwood's first moments on the screen, he's seen working in his garage, listening to jazz music, a nod to his real life devotion to the music form. Sutherland spends much of the film flashing his trademark loopy grin. It's that crafty smile we've seen time and again in films such as M.A.S.H and Backdraft. Jones plays off his acerbic, gruff screen persona to great effect, eliciting a pathos from his role that is truly bittersweet. Garner, by comparison, has a certain fuzziness to his character. His inclusion and role feels more like an afterthought than an integral part of the film.
Frank Corvin (Eastwood), "Hawk" Hawkins (Jones), Jerry O'Neil (Sutherland) and "Tank" Sullivan (Garner) are first shown as young men in 1958. They are Team Daedalus, the country's top Air Force pilots. In a gorgeously filmed black and white flashback, rebellious Hawk and rigid leader Frank are seen test piloting a jet plane, soaring high enough to see the moon, despite the blazing daytime sun. In a nice reference to Greek mythology, like Daedalus' son Icarus, they fly too high and come crashing to the earth. They have seen their prize, the moon, and both men dream of someday visiting it.
Flash forward to modern day NASA. There is a crisis involving a satellite of Corvin's design. It's in decaying orbit and falling towards earth. The only solution is an in-flight repair and Corvin is the only man who can do it. Realizing his strong negotiating chip, Corvin leverage's his way into Team Daedelus making the space trip.
Most of the film's heart beats in the pre-flight training the geriatrics must endure. There is an easy camaraderie between the stars and the tone of the film slides into an almost TV sitcom-like quality. Due to Eastwood's deliberate directing hand, the scenes play more sweetly amusing than cloying. Frank and Hawk, despite their age, get into a bar fight that plays like siblings venting life long grievances. The "Aw, Mom, we weren't doing nuthin'" looks they give a team supervisor upon explaining their shiners shows the actor's strength through subtlety. Hawk, sans computer assistance, shows two young, hotshot astronauts, how pilots flew in the old days. Jerry, with the practiced subtlety of a snake charmer, hits on any women within range of his droopy shouldered, coke bottle thick, be speckled sight. Eastwood sends the message that old means nothing more than wiser, maybe a bit smarter and still sexually potent.
There's almost an audible grate of metal on metal as the second half of the film grinds gears from a character driven focus to adventure. Although beautifully realized visually, the space rescue is truly unremarkable. Nothing occurs that we haven't seen in other recent films involving space travel. By shifting from the film's strong suit, its leads, to straightforward action, a certain momentum is lost.
If you're not looking for any big revelations or insight into the human condition, this is a movie for you. Space Cowboys doesn't try to present itself as anything other than what it is: Fun, eminently watchable, summer fare.

net.jini.activation
The
net.jini.activation
package provides extensions to the
Java(TM) Remote Method Invocation (Java RMI) activation framework.
ActivatableInvocationHandler
by default no longer attempts
to propagate dynamic permission grants from the dynamic proxy to the
underlying activation identifier. If this functionality is required, it can
be enabled by setting the
com.sun.jini.activation.enableActivateGrant
system property to
true
. If the
phoenix
activator has been configured
to allow anonymous client activation requests, and the invocation
constraints on the underlying activation identifier have been configured
to allow anonymous activation calls, it is not necessary to enable this.
That should be the preferred configuration. However, if the activator has
been configured to use Kerberos authentication, then anonymous calls are
not supported, and you will either have to enable the activate grant in
clients and dynamically grant sufficient
AuthenticationPermission
and
GrantPermission
to the proxy to permit activation calls
to succeed, or else statically grant sufficient
AuthenticationPermission
to downloaded code in clients
to permit activation calls to succeed.

These chunky fish cakes have a delightfully crisp crumb and surprise in the middle.
Cook the potatoes in a pan of boiling water for 15 minutes, or until tender. Drain, then return the potatoes to the pan and heat for one minute to drive off any excess moisture. Mash the potatoes, or pass through a potato ricer into a bowl. Set aside to cool slightly.
Stir in the parsley, spring onions, lemon zest and juice until well combined. Season with salt and pepper. Fold in the haddock.
Divide the mixture into 8 equal portions. Place a soft-boiled quail's egg in the middle of 4 portions and cover them with the remaining portions. Shape into 4 balls.
Half fill a large saucepan with the oil and place over a medium heat. If you're using a deep-fat fryer or have a thermometer, heat the oil to 180C. If not, to check the oil is at the right temperature, drop a 2-3cm/¾-1¼in cube of bread into the hot oil. It should be golden-brown and crisp within 1 minute (CAUTION: hot oil can be dangerous. Do not leave unattended).
Put the flour, beaten egg and breadcrumbs into 3 separate bowls. Dredge the fish cakes in flour, dip in beaten egg and finally coat in the breadcrumbs. Deep fry them (in batches if necessary) for 2 minutes, or until golden-brown. Drain on kitchen paper.
For the mayonnaise, place the egg yolks, vinegar and mustard in a food processor and blend. With the motor running slowly add the oil in a thin stream until emulsified. Remove from the blender and stir in the curry powder, turmeric and lemon juice. Season with salt and pepper.
For the garnish, place the watercress in a large bowl. Place the vinegar, mustard and oil in a small bowl and whisk to combine. Just before serving add the dressing and mix.
Place the mayonnaise in the centre of each plate and top with the fish cakes and garnish with dressed watercress.

. Also, sometimes this could be the result
of mistakenly concatenating a string format argument by typing a '+' when a ',' was meant.
Example:
static String formatGreeting(String userName) {
return String.format("Hello, " + userName);
}
Here, the userName
will be interpreted as a part of format string, which may result
in IllegalFormatException
(e.g. if userName
is "%"

using enrmous amount of memory (e.g. if userName
is "%2000000000%"

Here, it's better to use String.format("Hello, %s", userName);

I have none.
I have not contributed to my knowledge.
I have contributed and volunteer to the Mountain Resource Center in Conifer, CO as a worker.
I am very concerned about the direction of recent politics and over tone of the electorate. I would like to be a part of solving some of the pertinent issues in our State, in a bi-partisan, civil manner, as fair as possible for all.
"Promote consensus or contribute to creating agreement". Is that possible in our current political state? Yes, I believe it is, when we discuss the lines we'll be drawing for a decade...a generation. Permanence or at least a durable period solidifying the lines that determine the districts, should clear the "now", and clarify the importance of discussion, compromise, and agreement by the majority parties in this commission. I understand the importance of a "win, win, win" for the parties involved, and mostly for Coloradans.
I have been involved in the negotiations of billions of dollars in mortgages and mortgage backed securities in packages valued between several million to several billion dollars. Each transaction requires a different set of negotiations and analysis. One of my positions in the acquisitions process was running the auditing of the origination, servicing, history, and collateral for loan, in every pool. Our analysis was quite comprehensive, and modeling to a pricing scenario, but agreeing to the transaction with the sellers/buyers took a lot more reasoned logic and negotiations. Compromise and modification by both parties, normally brought the deal to a conclusion satisfactory by all.
