Colin Kaepernick is one step closer to finding his way back to the gridiron.
The quarterback – who last played for the San Francisco 49ers in 2017 – will participate in a private NFL workout for at least 11 franchises in Atlanta this Saturday. Those 11 teams include the Arizona Cardinals, Atlanta Falcons, Cincinnati Bengals, Cleveland Browns, Dallas Cowboys, Denver Broncos, Miami Dolphins, New England Patriots, New York Giants, New York Jets, and Washington Redskins.
Check out our ranking of which teams could best put Kaepernick’s talents to use:
11. Dallas Cowboys
Dak Prescott has started for America’s team since 2016, and in that span, he’s led Dallas to a 37-20 record with a 66.5 completion percentage and a 97.1 quarterback rating. It seems unlikely that Jerry Jones would divert away from his quarterback at this point. However, Prescott’s backup, Cooper Rush, does not have much game experience to this point, so Kaepernick would be a much more seasoned option to step in should anything keep the Cowboys’ QB1 off the field.
10. Atlanta Falcons
Nobody is taking the starting job away from Matt Ryan, who has been to four Pro Bowls and was named the 2016 NFL MVP. Backup Matt Schaub, who is 38 years old, owns a career record just one game above .500. Kaepernick could undoubtedly be a worthy replacement on the Falcons’ depth chart, although at 32 years old, he wouldn’t make much of an heir to 34-year-old Matt Ryan’s legacy in Atlanta.
9. Arizona Cardinals
The Arizona Cardinals made Kyler Murray their guy when they selected him first overall in this year’s draft and traded away Josh Rosen. Still, at just 22 years old, Murray is young and could stand to learn from an experienced star like Kaepernick.
8. Cleveland Browns
The Cleveland Browns thought they found their guy in former Oklahoma Sooner Baker Mayfield when they drafted him with the first overall pick in the 2018 NFL Draft. In his rookie season, he led the team to a 7-8-1 record and accrued more wins than the team had earned in the previous three seasons combined. Mayfield has undoubtedly brought hope to a team that was, until very recently, the butt of every joke, but there’s no denying that his sophomore season has been lacklustre. He currently owns both the second-worst quarterback rating and the second-worst completion percentage in the league despite the franchise’s addition of multiple targets during the offseason. Kaepernick would make a worthy backup for Mayfield and could even challenge him for the starting spot.
7. Miami Dolphins
Career journeyman Ryan Fitzpatrick is a decent option for the struggling Miami Dolphins at the moment, but he’s 36 years old and certainly isn’t the future of the franchise. They have been rumoured to have their eyes on Alabama quarterback Tua Tagovailoa. Still, a veteran presence to help share the load and guide the young quarterback into the NFL certainly couldn’t hurt.
6. New York Giants
Rookie Daniel Jones stepped in early on this season to replace a dwindling Eli Manning for the New York Giants. He’s had flashes of brilliance since, but his turnover rate is an area for concern for Big Blue faithful. At the very least, Kaepernick could be a solid backup for Jones once Manning retires. At best, he could take charge and lead a fragmented franchise back to relevance.
5. New York Jets
Sam Darnold has the worst interception percentage and quarterback rating in the NFL. The Jets are just 2-7 on the season, and first-year head coach Adam Gase is under considerable pressure to right the ship. Perhaps Kaepernick could be part of the equation.
4. Washington Redskins
Rookie quarterback Dwayne Haskins has been charged with leading Washington out of its abysmal start to the season. He’s yet to secure a win or throw for a touchdown in three games, so he’s far from secured his spot for the future. Kaepernick would be a tried and true option for Washington, but whether the civil rights activist would be willing to wear a jersey emblazoned with a racial slur remains to be seen.
3. New England Patriots
There are serious doubts regarding whether or not Tom Brady will return to New England after the 2019-2020 season. If the GOAT and Bill Belichick finally part ways, there is no obvious heir to the throne for the Patriots. Jimmy Garoppolo has taken his talents across the country to San Francisco, and neither of Brady’s current backups has significant experience. Kaepernick could be a logical answer to take over the New England empire.
2. Cincinnati Bengals
The winless Bengals benched veteran quarterback Andy Dalton for rookie Ryan Finley, but neither has done much to pull Cincinnati out of its prolonged slump. The franchise will undoubtedly be well-positioned to draft a top quarterback – think Tua Tagovailoa, Joe Burrow, or Jake Fromm – but Kaepernick’s experience could go a long way in helping the team pull itself back into contention.
1. Denver Broncos
The Broncos have four quarterbacks in rotation at the moment, but none has found prolonged success in the Mile High City. Joe Flacco is on his way out, and rookie Drew Lock has remained off the gridiron due to a combination of injury and inexperience. If Kaepernick is in shape to be the player he was back in San Francisco, he could be an excellent option out in Colorado.


What is Big-O?
(Plus a little bit on linear vs binary searches)
August 5, 2015
Big-O is a measure that represents the complexity (and thus efficiency) of a computer algorithm. Okay, that was easy, blog finished.
But seriously, Big-O is a subject that any programmer who hopes to write efficient programs needs to understand. This week, the designers of the Dev Bootcamp curriculum have granted us students the freedom to discuss a topic of our choice, and for me it had to be Big-O.
Big-O and Order (When Big)
Big-O is in essence a mathematical concept that measures the order of an equation as it approaches a limit, that is, when the input gets really, really big. As you may or may not remember from algebra class, the order of a function (or more accurately, the degree of a polynomial) is determined by its largest exponent, and the larger the exponent, the faster the y values climb:
The orange graph, y = x3, is a third-degree polynomial, and it rises faster than either y = x2 or y = x. Zooming out further would show this effect even more clearly.
But what does this have to do with programming? And might it be possible to discuss this without using an abstract example from math classes of bygone years?
Big-O and Programming
To see how this applies to programming, let’s return to the graph above (last time, I promise) where the x value represents the number of things we need to process and the y value represents the number of steps it takes to process them. If there are only 2 things we need to process, it doesn’t make too much of a difference in terms of computer times (usually on the scale of nanoseconds) whether our algorithm takes 2 steps (y = x), 4 steps (y = x2), or 8 steps (y = x3) to accomplish this.
But at 10 things to process, the differences become much starker: 10, 100, and 1000 steps respectively. Bump up our number to 1000 or 1,000,000 things to process and performance time (and/or data usage) quickly becomes a major issue. Once we start talking about huge numbers like one million or one billion, we’re testing our algorithm to the (mathematical) limit and examining its “worst-case performance scenario.”
A Children’s Game and Big-O
I don’t know about you, but I can vividly remember from childhood playing a game where one kid would think of a number between 1 and 100, and the other kids would see how quickly they could guess it, using “higher” and “lower” as cues. I could immediately tell which of my classmates (and siblings) were mathematically inclined by analyzing their guessing patterns. Those who were mathematically inclined would guess according to an optimized pattern, whereas those who were not would guess haphazardly without a clear method.
Guessing haphazardly (or linearly from 1 to 100) could end up taking 100 turns to establish the correct number. Whereas I would always be able to guess within 7 guesses (50 -> 75 -> 63 -> 57 -> 60 -> 62 -> 61 being one such worst-case scenario).
Now let’s return to our computer—surely there’s not much difference in performance between taking 100 rounds or 7 rounds, but what if I were thinking of a number between 1 and 1,000,000,000 or, shifting gears a bit, thinking of a specific Facebook user from the 1.5 billion users that have active accounts. This is the limit case where we can really see the underlying efficiency of an algorithm.
Linear Search vs Binary Search
You might be surprised to learn that the two ways that children try to guess a number between 1 and 100 (haphazardly/linearly or by homing in using midpoints) closely mimic two different ways to perform computer searches over data collections.
A linear search takes a total of two steps each time it examines a data point—one step to increment the index, and a second step to perform a comparison. An abstract version in Ruby for searching arrays might look something like this:
def linear_search(array, target)
array.each_with_index do |element, index|
if element == target
return index
end
end
return nil
end
A binary search requires a total of three steps each time it looks at a data point—one step to calculate the midpoint (choose the index), another step to perform the comparison, and then another step to redefine the boundaries of the search. Note that a binary search will only work on sorted arrays (it is ineffective on unsorted arrays). A generic Ruby method for performing binary search on sorted arrays that uses recursion would look like:
def binary_search(array, target, min = 0, max = array.length - 1)
if max < min
return nil
else
mid = (max - min) / 2
if array[mid] > target
binary_search(array, target, min, mid-1)
elsif array[mid] < target
binary_search(array, target, mid+1, max)
else
return mid
end
end
end
And yet, despite the fact the linear search takes 2 steps each round and the binary search takes 3, the binary search method is much, much, much quicker for the same reason that the child who uses midpoints to guess a number between 1 and 100 finds his answer much more efficiently.
If we needed to search through an array of one million (n) sorted names, in the worst-case scenario it would take the linear search two million (2 * n) steps. Whereas the binary search would take twenty rounds in the worst-case scenario, or 60 total steps (3 * log2n = 3 * 19.931569 ≅ 60). (The number of rounds in the binary search shows base 2 logarithmic growth.) Even with smaller array sizes, the binary search proves to be more efficient:
To translate our results into more human terms, if it took a (very, very slow) computer one second to perform each step, it would take up to 11.5 days to perform a linear search of one million pre-sorted names, whereas the binary search would take a minute at the most! This shows the utmost importance of writing efficient algorithms when dealing with big data collections.
Big-O Notation
When we’re talking about Big-O, we’re talking about limit cases, so when we’re dealing with numbers like 1,000,000,000 there’s really not too much difference between n and 3n or log10n and log2n. There is, however, a huge difference between n2, n, and log n (1018, 109, and 9, respectively).
That’s why when we derive Big-O for an algorithm, we only worry about the highest order that exists in the function, and don’t concern ourselves with coefficients, constants, or “lower-order” variables (for example, 3x2 + 6x + 10 simplifies to x2 for Big-O purposes).
So, in the case of linear search, its Big-O is written as O(n), while the Big-O of binary search would simply be O(log n). Again, we can graphically see where a Big-O of O(log n) is much better than O(n)—recall that x represents the number of data points and y represents steps taken (time and/or memory cost):
Further Resources
Of course, the linear and logarithmic cases for the two search methods explored above are not the only possible orders for Big-O. Eric Rowell’s site provides a great overview in both chart and graphical form of the Big-O of various algorithm types (and in particular competing sort algorithms) and their best-, average-, and worst-case scenarios as well as what their “cost/complexity” curves look like. More in-depth, scientific explanations of Big-O as it pertains to mathematics and computational complexity are available in Computer Science textbooks and elsewhere on the web in the usual places (Stack Overflow, Wikipedia, etc.). But I hope that this blog post has at least provided you, my readers, will a solid foundational understanding of what Big-O is and why it matters. Onwards and upwards, fellow Big-O’ers!

The implementation of CosTransactions::Current. In a multi-threaded environment where threads can terminate transactions they may not have started, then it is possible for a thread to call commit/rollback/rollback_only on a transaction which has already been (or is in the process of being) terminated. We assume that the subsequent thread is still associated with the transaction so that it can determine its status, rather than simply disassociate it when it tries to terminate and return NoTransaction, so we would return INVALID_TRANSACTION. This allows us to distinguish between the situation where there really is no transaction associated with the thread.- Since:

suspend
public org.omg.CosTransactions.Control suspend() throws org.omg.CORBA.SystemException
The spec. states that after suspend we should have a null transaction context, but is hazy as to what to do if we are nested. We shall assume that the control returned is for the current transaction and that we suspend the entire transaction hierarchy. Given the returned control, we can always regenerate the hierarchy later if required by resume.- Specified by:

resume
public void resume(org.omg.CosTransactions.Control which) throws org.omg.CosTransactions.InvalidControl, org.omg.CORBA.SystemException
To support checked transactions we can only resume if the action is local or we received it implicitly. If the control refers to a nested transaction then we must recreate the entire hierarchy, i.e., the effect of a suspend/resume on the same control should be the same as never calling suspend in the first place. If the control is for a local transaction then it is simple to recreate the hierarchy. Otherwise we rely upon the PropagationContext to recreate it. If this control is a "proxy" then create a new proxy instance, so we can delete proxies whenever suspend is called. Should check if "new" transaction is not actually the current one anyway. If so, just return. The spec. doesn't mention what to do in this case, so for now we go to the overhead of the work regardless.- Specified by:

IN THE HIGH COURT OF KERALA AT ERNAKULAM Tr.P(Crl.).No. 91 of 2007() 1. R.GOKUL PRASAD, AGED 39 YEARS, ... Petitioner Vs 1. M/S.HINDUSTAN COCO-COLA BEVERAGES (P) ... Respondent 2. SANJEEV GUPTA, OCCUPIER & PRESIDENT, 3. VINEETH KUMAR KAPILA, 4. N.JANARDHANAN, AREA MANAGER 5. STATE OF KERALA, REP. BY PUBLIC For Petitioner :SRI.S.RAJEEV For Respondent :SRI.E.K.NANDAKUMAR The Hon'ble MR.  Certain remarks made by the learned Magistrate in the course of the proceedings appear to have instilled in the mind of the petitioner a reasonable apprehension that he may not get justice at the hands of the court.
2. The courts have to be very careful while making observations. A most unintended observation may also generate doubt in the mind of a litigant about fairness of the procedure. I am of the opinion that it is not necessary to go into further details.
3. In the course of discussions, this court suggested that the case could be transferred to the court of Chief Judicial Tr.P.C.No. 91 of 2007 2 Magistrate, Palghat, which will be convenient to all the parties and without any further discussions the case can be transferred. The said suggestion is acceptable to the parties. I am satisfied that the interests of justice will be eminently served by directing the transfer as prayed for.

It's important for web designers and developers
to realize that what they see currently on their computer,
at their resolution, with their browser and their operating system
is not going to be necessarily the same thing that everybody else sees.


REST is a way to implement web services. This article explains about the request and response for a REST service.
Everything is a resource in REST. URI is used to locate a resource in REST services.
URI contains the following:HTTP methods are mapped against REST services. Since REST is lightweight.
GET : This would get collection of the resources in a given URI. Response can be in any data type from JSON to binary.
POST : Request will also contain data sent to
server. Server will be able to process the Post data. Response can be again in any type from JSON to binary.
PUT : Request to create new item to the collections. New item shall be created with data present in the request.
DELETE: This
should be ideally be used to delete the resource pointed by the URI.
There is no need to create a stub/proxy in client application to consume REST services. This is because there is no binding definition involved for these web services.
However, there is a need for asynchronous call from client. Call to service
might take time to provide a response. During the service call, it is important to not block user interaction on the screen. These scenarios must be handled by UI developers with extra coding. This can be viewed as small overhead.


Welcome to the third pre-release of Kixx! (version 0.7)
Warning: Pre-Release software ahead; beware of the sideways bicycle.
Kixx is brought to you by The Fireworks Project
The Kixx Bootstrapper is an extension designed for the Mozilla Firefox web browser that provides a plugin platform for a modular system of applications called "toolpacks".
The main goal of Kixx is to provide a simple means of installing, persisting, importing, and managing client side modules including code libraries and user facing toolpack applications. The philosophy behind Kixx is to maintain an extremely modular environment, facilitating more efficient and innovative development of complex Internet enabled software systems using web browsers as the platform. The Kixx environment is designed to use common web technologies including (X)HTML, CSS, and JavaScript.
With a priority on being modular, Kixx provides toolpack developers with the CommonJS modular JavaScript architechture. You can learn more about CommonJS on the wiki.
It is important to note that Kixx is in the very early stages of development, and what you are looking at here is a pre-release alpha version. Do not expect it to be stable, bug free, or user friendly.

Defining based on prefix/suffixes matching and allow space inside the label text.
Completed
Need to switch notation from infix to prefix for assignment ops
Added EvalSymbol which lets you construct your own Symbol and send it to the VM (like Eval without the parse step)
need an EvalString function that takes a function table, symbol table and input string and either writes a string to stdout, make a new assignment or emits an error message with line number
need a RegisterOp function that takes a string and a function and stores the result in a function table
make a decision about labels being immutable or not.
pros is it simplifies handling significantly, also makes playback easier (makes things functional)
cons if you’re typing in the repl you’re going to want to replace a label’s content periodically as you explore and make mistakes
add line number ranges when including include files.


‘LBDI Still Enjoys Correspondent Banking Relationship with Citibank;’ Terms Media Speculations “Untrue and Baseless”
by Press ReleaseMonrovia – The Liberian Bank for Development and Investment, is a full-service bank of Liberia, says its attention has been drawn to speculations in some section of the media that Citi Bank in New York has dropped it as money transfer partner and Qatar Bank also turned it down for US$50M loan.
According to the only Liberian bank, the story is “UNTRUE and BASELESS.” “The LBDI continues to enjoy correspondent banking relationship with Citibank, New York even up to the time of this press release. LBDI and Citibank have enjoyed mutual relationship for decades and is the only banking institution in Liberia that has direct money transfer relationship with Citibank, New York,” the bank said in a release issued Thursday, November 21.
The Bank further clarified that at no time has it engaged a Qatari Bank for financing neither has a Qatari Bank offered financing to it.
“The LBDI wishes to assure its valued customers and the general public that these speculations are intended to instill fear in the public.”
LBDI was founded in 1961 and it is based in Monrovia. The bank is involved in consumer banking as well as in development banking. It has 12 branch offices in Liberia. In the field of consumer banking, the bank offers internet banking and Western Union and MoneyGram services.

Hey, Blake Womack here. Welcome to my portfolio page. I'll be working on this page off and on throughout the next six months adding to it and trying to make sure it reflects my best work. I like my work to be beautiful and tidy, just like Switzerland. So if you've ever been there you know what I'm talking about. Remember, it was a Swiss typeface designer that invented Helvetica.
I just spent the last five years working at Intel as a contingent worker helping them publish their public facing website. Prior to that I earned a Digital Design certificate from PSU. I had been working in the Standby/Stationary Power Industry but left that to pursue a career that more closely aligns with my art degree.
I was born in Dallas, TX but soon after graduation from college I left. I have lived all over the country and each place I have lived still has a little chunk of me blowing around on its streets.
I'm pretty sure I have at least one more move in me.
These use html and css, and of course GitHub.

Eno is a tool that generates survey questionnaires starting from their formal description in DDI. It automates the production of “collection instruments” (paper or web forms, collection modules for surveyors, etc.) based on a formal and abstract description of the questionnaire as standardised metadata. These models are then used to produce the collection media, in different modes, within production collection infrastructures. Eno is used by Insee since 2015 : more than 30 business surveys are using Eno for their web and paper questionnaires, and the offer for household surveys is growing.
The use of standard description in DDI provides and enforces structured information (and consequently leads to well structured questionnaire). This choice of DDI as a modelling format for questionnaire specification was motivated by : - A strong need for a precise modelisation of the questionnaire in order to be able to render its content and logical flow in different collection modes (i.e a semantically rich model) - DDI being an open standard - DDI being serialised in XML, and thus easily processable.
Since 2015, Eno takes as input the formal description of the questionnaire complying with the DDI standard and executes a completely automated chain of transformations to produce the current survey questionnaire (web and paper questionnaires).
DDI description enables to identify clearly the different components of a questionnaire, such as sequences of questions, questions, instructions, different formats of response.
Common used response formats are available : simple text, number, date, single choice question, multiple choice question, grid question.
It is possible to incorporate dynamic layout : filters and questionnaire logic flow, loops, controls to check the format of the input fields, consistency between the different input fields and, where necessary, with previous collected data. Controls are emphasized by probing messages to invite respondent to correct or fulfill his response.
Outputs of Eno : the questionnaires can be created in different formats from the same description : XForms web questionnaires (executed on Orbeon Forms Runner), fo output format for paper questionnaires (the FO is transformed into PDF by a module based on Apache FOP), or questionnaires in a dedicated format which will be used for face-to-face or telephone collection.
When they are personalized, the "collection instruments" can be pre-filled with previously collected data or from a register by instance, and labels can be customized with informations on the respondent, already known before data collection as well as collected previously in the form.
The development of one tool, based on standardised description in DDI leads to a standardized design. It ensures that questionnaires comply with standards and recommendations on survey design. The distinction between questionnaire's elements allows to show them in different ways and styles, and to create a coherent layout for questionnaires produced.
Display choices are also shared between surveys within the NSI, improvements are available/profitable for every users at the same time. For the household or business surveyed,it enables them to better identify surveys that are indeed within the official statistics remit.
The generation of different data collection formats from the same questionnaire description supports unimode design for mixed mode surveys. The description is done once : the use of the generator lightens the burden of work for the survey departments.
The questionnaire documentation can be stored and reused, in a global NSI context, or for a similar survey from year to year. Classifications are shared between different surveys teams.
Eno is a stakeholder in active metadata : as the end of the "survey process", the questionnaire description can also (and will) be reused for dissemination or documentation of surveys.
Eno is very widely, even systematically, used in business surveys (web questionnaire, paper questionnaire, takeover and management tool). Household surveys have also started to use it and work is underway to increase the functional coverage required for these surveys (e.g. description of filters, possibility to loop or select occurrences of a loop, interviewer questionnaire).
Eno is published as open source on a GitHub repository. It is available under the MIT license, and contributions as well as suggestions for improvements are welcome.
It is developped in an international perspective, codes and comments are in english. Data of course can be collected in any langage.
How to use it?
Eno comes packaged in various ways: as a command-line tool, a REST web service and a Docker image.
ENO is often associated with Pogues. This is is an additional module to Eno, a questionnaire design user interface, that connects with the generation process. Pogues produces the DDI description of the questionnaire : using this tool, a questionnaire designer can specify his web questionnaire in a friendly way and visualize the generated result in one click.

WWE Rumors: Creative team pushing for Triple H to compete in blockbuster match at Survivor Series
by Danny HartThe 2019 WWE Survivor Series pay-per-view has a RAW vs. SmackDown vs. NXT theme, with Superstars from all three shows battling it out for brand supremacy in multi-person matches.
Team RAW (Seth Rollins, Drew McIntyre, Kevin Owens, Randy Orton and Ricochet) and Team SmackDown (Roman Reigns, Mustafa Ali, Braun Strowman, King Corbin and Shorty G) have been confirmed for the men’s five-on-five-on-five elimination match, but the Superstars on Team NXT have not yet been announced.
Wrestle Votes is reporting that there has been a push from WWE’s creative team to have Triple H compete on Team NXT in the elimination match, but the 14-time World Champion does not want to be part of the event as an in-ring competitor.
Speaking to talkSPORT earlier in 2019, the NXT boss said he often gets requests for both him and Shawn Michaels to join the NXT roster, but he has no plans to compete for the black and gold brand.
“Trust me, there’s almost a day that doesn’t go by where I don’t get a text from somebody on these rosters who go ‘what if…’ or ‘what if Shawn…’ or ‘what if you…’ and that’s flattering, I understand that. Look, I watch what they do – I couldn’t hang! Not even in the ballpark anymore.”
Triple H’s most recent WWE matches
In 2019, Triple H defeated Batista at WrestleMania 35 before losing against another former Evolution colleague, Randy Orton, at the Super ShowDown event in Saudi Arabia in June.
He also competed in two tag team matches during WWE’s trip to Tokyo, Japan in the summer, but he did not participate at the recent Crown Jewel show in Riyadh.
“The Game” has still appeared sporadically on WWE television, though, most notably on the November 1 episode of SmackDown when he led NXT’s invasion of the blue brand to send out a message ahead of Survivor Series.
Now you can rate RAW, SmackDown and NXT matches on Sportskeeda !


Electrical Engineering
Electrical engineering is a field of engineering that works with electricty, electronics, electromagnetism. Originally I didn't have that much of an interest in this field, I had an interest in biomedical engineering. Now I have found that electrical engineering is more interesting to me. When we worked with Arduinos on Thursday, I found it a lot of fun.

Legit is a complementary command-line interface for Git, optimized for workflow simplicity. It is heavily inspired by GitHub for Mac.
Feature branch workflows are dead simple.
$ git sw <branch> # Switches to branch. Stashes and restores unstaged changes. $ git sync # Synchronizes current branch. Auto-merge/rebase, un/stash. $ git publish [<branch>] # Publishes branch to remote server. $ git unpublish <branch> # Removes branch from remote server. $ git branches [wildcard pattern] # Nice & pretty list of branches + publication status. $ git undo [--hard] # Removes the last commit from history.
If you are using Homebrew:
$ brew install legit
Or install legit
via pip
:
$ pip install legit
To enable the git
aliases:
$ legit --install
Nice and simple — the way it should be.


Limit the access to the credential store. Unauthorized access to the credential store can lead to users' credentials being overwritten, thereby allowing the attacker to gain access to application resources without obtaining valid credentials prior to the attack.
The following code authenticates a user based on their credentials. Because the code discloses the credentials to the user database, anybody with access to the code also has access to the credential store.
public boolean validateUser(String user, char[] pass)
{
boolean valid;
Connection cn;
// Prepare credentials before querying the credential store
...
try
{
// The application discloses the credentials necessary for
// accessing the user database
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
cn = DriverManager.getConnection("jdbc:oracle:thin:@testbox:1521:orcl2",
"myapp", "pass");
// Query the credential store and perform the rest
// of the authentication steps
...
}
catch (SQLException se)
{
// Add the appropriate logging and exception handling mechanisms
return false;
}
return valid;
}
The following code authenticates a user based on their credentials. The code relies on other parts of the application to handle database connectivity. Therefore, the code does not reveal the application's credentials to the credential store.
public boolean validateUser(String user, char[] pass)
{
boolean valid;
// Prepare credentials before querying the credential store
...
try
{
// The credentials to the application's user database
// are not hard-coded in the authentication routine
cn = MyApp.getDBConnection();
// Query the credential store and perform the rest
// of the authentication steps
...
}
catch (SQLException se)
{
// Add the appropriate logging and exception handling mechanisms
return false;
}
return valid;
}


I've never been a big user of the command line. One could even say I actively avoided it! Heck, I haven't even written a program using command line arguments, since it always felt a bit like resurrecting a dinosaur - and we all know how that ends.
This carefully honed ignorance just came in handy when discussing how to improve the learning curve for Julia's shell interface.
Turns out it was designed by people born in the command line, making it confusing to use for someone like me. Now enlightened of how things work, I want to share my newly acquired knowledge!
Let's start with the basics and my first mental model. You can run a command like this:
julia> run(`julia -e 'println("hello world")'`);
hello world
Since this looks exactly like what I would type into the terminal, I inferred that this is the general rule: Just make it look like a command and it will run like a command!
But this falls apart as soon as we start interpolating into the command. Let's consider the following:
julia> flag1 = "-e 'println(\"hello world\")'";
julia> flag2 = "println(\"hello world\")";
julia> helloworld = "hello world";
julia> `julia $flag1`
`julia "-e 'println(\"hello world\")'"` # okay?! Guess strings get quotes
julia>` julia -e 'println($helloworld)'`
`julia -e 'println($helloworld)'` #what?
julia> `julia -e $flag2`
`julia -e 'println("hello world")'` # WHAT? Where are my "
julia> a = "some thing";
julia> b = `some thing`;
julia> run(`echo $a`);
some thing
julia> run(`echo $b`);
some thing
If this all makes sense to you, welcome to the group of enlightened people!
I looked more like this:
Obviously this is all well thought out and what was missing is the right mental model.
First of all, keep in mind that there is always a main
sitting somewhere, patiently waiting for you to feed it an array of strings.
The good ol' main(int argc, char** argv)
!
Now, what the shell does is splitting the one command string we type in by spaces in order to pass it to this main. This then obviously needs a method to create a string with spaces, which is where '...'
or "..."
comes into play. If I understand correctly, all other characters are just conventions. So the minus in -e
isn't treated special, as I assumed at some point. And therefore the -e
and 'println("hello world")'
only belong together semantically, but not when constructing the array of strings. So trying to interpolate '-e'
together with the '...'
block failed miserably, since Julia tried to interpret it as one string. What made me fail to see the correct solution was, that Julia can actually do better than the shell, since we can directly pass an array of strings to the command. So this actually works:
Julia
run(Cmd(["julia", "-e", "println(\"hello world\")"]))
Note that the above is equivalent to:
Julia
run(`julia $(["-e", """println("hello world")"""])`)
So we can in fact have better interpolation, since we just need to insert a new string into the array.
Which is why this actually works:
julia -e $("println(\"hello world\"))
Just leave out any '...'
and let Julia turn it into a command with correctly escaped strings.
Now, in Julia 0.7 Keno Fischer added a way of printing that makes the array nature of a command much clearer:
Together with a few documentation improvements, I think this can fly even for dummies like me :)


Classes
The following classes are available globally.
-
This is a very simple “persistent user prefs” class. It is instantiated as a SINGLETON, and provides a simple, property-oriented gateway to the simple persistent user prefs in iOS. It shouldn’t be used for really big, important prefs, but is ideal for the basic “settings” type of prefs most users set in their “gear” screen.

This class is the first controller to appear when the app starts.
Its job is to handle all of the connection and login stuff. Nothing else in the app can be done until it has passed this stage.
Once the user has successfully logged in, the Navigation Controller will bring in the main tabbed interface.
This View Controller starts off with a URL text entry, and a simple connect button.
Once the user has sucessfully connected, they are presented with a login screen.
This class is a big fat, stateful mess. Because the UX is best served by simply changing the state of a single screen, as opposed to switching in and out of screens, I work by showing and hiding batches of controls.
Yeah, it’s messy. Sorry.

How expressive (i.e. energetic, emotional, passionate) do you think the speech is? (regardless of the content)
How easy is it to follow the speech, given the verbal clarity,
the fluency and the rate of speech for the particular content being described?
(Note: Fluency, clarity and rate can be interconnected and correlated, e.g. one speaker can make his speech very easy to follow,
despite the fact that he speaks very fast,
while another speaker can speak slow and yet not making his speech easy to follow)
Did you enjoy listening to that speech (was the speech engaging, entertaining, motivating or compelling)?


This is my quick and dirty page on dinosaurs. It's really not designed to have a lot of content, but more as an example of HTML.
Unfortunately, there is not going to be a lot of style on this page, but maybe someday we'll fix it up to look a bit nicer.
My Favorite Dinosaur
Ever since I saw Jurassic Park, one of my favorite dinosaurs is the velociraptor. The kind of funny thing is that the "velociraptors" in the movie and book are actually modeled after deinonychus, a slightly larger, related species found in Montana. Both belong to the family Dromaeosauridae, which includes several other raptor species.

Preheat the oven to 180C/350F/Gas 4.
Blend the butter, garlic, lemon juice, lemon zest and tarragon in a food processor until well combined.
Turn out the mixture onto a sheet of cling film and roll it into a cylinder. Chill in the freezer for five minutes.
Using a sharp knife, make a deep slit into the side of each salmon fillet to form a pocket.
When the butter mixture has chilled, slice it into four pieces and insert one into each of the pockets in the salmon fillets.
Sprinkle the flour onto a plate. Beat the egg in a bowl. Mix together the breadcrumbs and polenta on a separate plate. Season the mixture, to taste, with salt and freshly ground black pepper.
Dredge each stuffed fish fillet first in the flour, then dip it in the beaten egg, then roll it in the breadcrumbs mixture until completely coated.
Heat the oil in an ovenproof frying pan over a medium to high heat. Add the coated salmon fillets and fry for 2-3 minutes on each side, or until the breadcrumb coating is crisp and golden-brown.
Transfer the salmon to the oven and cook for a further 8-12 minutes, or until cooked through. (NB: The salmon is cooked through when the flesh is opaque.)
Serve with new potatoes and spinach.

Best Song App
Description
An application that lists artists and allows users to vote for their favorite songs by artist, and
suggest new songs to vote on.
User Stories
- Stories guide development- how will your product be used?
- Should be for small, testable features
- Written with input from the stakeholders
- Formal format is: As a (role) I want (goal) so that (reason).
- Give them a priority ("required", "nice to have", "v2")
- Give them an estimated time/size (how hard will this be to do?)
- During the project, stories may change, be broken into smaller pieces, be re-prioritized or
re-estimated
User Story Examples
- As a user, I can backup my entire hard drive.
- As a user, I can indicate folders not to backup so that my backup drive isn't filled up with things
I don't need saved.
- Parking passes can be paid via credit cards.
- Students can only enroll in seminars for which they have prerequisites.

App Architecture
- Models
- Data Associations
- Controllers
- Views
What do we need?
Let's Build an App!
Generating Models
$ rails generate model Artist full_name:string
$ rails generate model Song title:string artist:belongs_to
$ rails generate model Vote song:belongs_to
Migrations
Generating models also generated database migrations for us. Let's check them out and make sure they list
the attributes we want.
Migrations
Let's add 'current hairstyle' attribute to Artist table!
Since the migration hasn't been run yet, we can just edit it to add the new column.
def change
create_table :artists do |t|
t.string :name
t.string :current_hairstyle
t.timestamps
end
end
Ok, now that it looks good, run the migrations.
$ rake db:migrate
Migrations
- Migrations describe changes that will be made to the database.
- They use a Ruby DSL so you don't have to write SQL.
- Each migration modifies the database's schema, which you can see in your db/schema.rb file.
Migrations in more
detail...
Migrations
It would be pretty cool if songs has an attribute called 'optimal volume'. Let's create a migration to
add that to the table.  Now run the migration ('rake db:migrate') so the schema is up to date.
Let's Develop It!
Generate a migration to add a column called 'hometown' with a type of 'string' to the Artists table.
Data Associations
The second part of building data associations is in the models.
class Artist < ActiveRecord::Base
has_many :songs
end
class Song < ActiveRecord::Base
belongs_to :artist
has_many :votes
end
class Vote < ActiveRecord::Base
belongs_to :song
end
Data Associations
Rails supports six types of associations:
- belongs_to
- has_one
- has_many
- has_many :through
- has_one :through
- has_and_belongs_to_many
Note: the last two are not used very often.
Associations
in more detail...
Data Associations
belongs_to
This sets up either a one-to-one or one-to-many model with another mdoel.
If order belongs to customer, each order can be assigned to exactly
one customer.
In the order table, there will be an entry for 'customer_id: integer'.
The order model will say 'belongs_to :customer'. Note that 'customer' is singular!
The customer model will need to either 'have one' or 'have many' orders.
Data Associations
has_one
This sets up a one-to-one connection with a another model.
If supplier has one account, each supplier can have exactly one
associated account.
In the supplier table, there will not be a reference to accounts.
The supplier model will say 'has_one :account'. Note that 'account' is singular!
The account model will need to 'belong to' supplier.
Data Associations
has_many
This sets up a one-to-many connection with another model.
If customer has many orders, each customer may be associated with zero or more orders.
In the customer table, there will not be a reference to orders.
The customer model will say 'has_many :orders'. Note that 'orders' is plural!
Orders will need to 'belong to' customer.
Data Associations
has_many :through
This sets up a many-to-many connection to another model, through a third model.
A patient can have many physicians through an appointment and a physician can have many
patients through an appointment.
In the appointments table, there will be an entry for both physician_id and patient_id.
The appointment model will say 'belongs_to :physician, belongs_to :patient', and the patient model will
say 'has_many :appointments, has_many :physicians, through: :appointments'.
Data Associations
Index?
A database index is a data structure that improves the speed of data retrieval at the cost of more
storage space. An index is a copy of the selected columns, which can be searched very efficiently.
Summary
Today, we planned out our application by writing user stories and discussing the architecture. Then, we
generated the models that we'll be using, and hooked up the associations properly.
Homework
- Do the first three levels of Rails for Zombies
- Spend some time in the Rails Console with your Best Song App, creating, destroying, and updating
database records.

During Sprint five of EDA training we had to do an exercise where we created a 'FizzBuzz' program using JavaScript. The FizzBuzz program tells the user which numbers (between zero and one hundred) are divisible by three, five and which numbers are divisible
by both three and five.
When I first read the problem I was a bit nervous because I did not know where to begin to solve this problem. The first step to solve this problem was to use pseudocode. This is essentially writing out
the steps of the program in simple english. By doing this it helped me to understand how to structure the flow of the program with out getting bogged down in the syntax of Javascript.
Once I had a good understanding of how the whole program would work with pseudocode, I started looking at how each function would actually work in JavaScript. Since I am still learning to code I didn't know how to write the syntax to get certain things done. Therefore,
I opened up the Console in DevTools and started playing around with bits of code. The great thing about playing in the console is that I could quickly test ideas and see the result. For example to see to test if a number is divisible
by three I just went into the console and typed: '10 % 4' Answer: 2
This confirmed for me how I could go about testing numbers in my program. Every time I got stuck or was not sure about how to code a bit of logic, I just went into the console and tried something out until I found a solution.
Sometimes I found myself spending a lot of time in the console and not really getting anywhere. In those situations I tried googling for an answer. For example, In this program I needed to use something called 'conditional operators'. This means that if my program came met certain conditions then it needed to do something. In my program I needed to test if a number was divisible by three and by five. to find out how to do this I went to google and found out about the '&&' operator. This allowed me to combine two conditions and test if they were both true at the same time.
Often I would get error messages when I tested my program. One error message that I kept getting was that a variable was 'undefined'. This meant that the program was not getting a piece of data that it needed to execute some code. When I got this error message I carefully scanned my code and looked at all my variable names. I would use a troubleshooting technique where you 'console.log' the variable. I often noticed that I would spell variable names incorrectly and this is what caused that problem.
During this exercise I never felt so blocked that I needed to use the rubber ducky method or ask my peers for help. Note: The rubber ducky method is a technique where you talk through the steps of your code to a rubber ducky (or
some other object). However, I suspect there will be many times in the future when I will get stuck and will need to use these techniques.
Overall I felt really good about solving creating the program. I felt like I had the skills
to solve issues as they came up. At first I was a bit nervous as I did not know how to start. However, as I started writing down code I became more relaxed and focussed. When I completed the program, I looked back at the code and
reflected on how completed the exercise. I felt that I did a good job at tackling the problem in a logical way. I also liked the way I focussed on one small step at a time.
This function allows you to call a function on each element on an array. For example:
var arrayOfNames = ["Jim","Tim","Jane","Jess"];
var greeting = function(name){console.log("Hi " + name)}; arrayOfNames.map(greeting);
result: Hi
Jim Hi Tim Hi Jane Hi Jess
This function allows you to run each element in your array through a filter function. The filter function can be another function that you have created to sort through the items in the array.
For example: var ages = [32, 33, 16, 40];
function checkAdult(age)
{return age >= 18;}; ages.filter(checkAdult);
result: [32, 33, 40]
The reduce function allows you to reduce an array down to a single value. The function will allow you to perform a function on each element on the array. For example, in an array of numbers you can reduce it down to a single total like so:
var testArray = [1,5]
testArray.reduce(function(total,num){return total + num})
result: 6


Write a function that formats a string using placeholders.
var str = stringFormat("Hello {0}!","Peter");
//str = "Hello Peter!";
The function should work with up to 30 placeholders and all types
var format = "{0}, {1}, {0} text {2}";
var str = stringFormat(format,1,"Pesho","Gosho");
//str = "1, Pesho, 1 text Gosho"
