Based on the information from the following links:
Note that we need to set "VS150COMNTOOLS" to "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\vsdevcmd\ext" (instead of "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build").

Fixed "Apache2 Startup warning: NameVirtualHost *:80 has no VirtualHosts"
Based on the information from the following two links, I could remove this annoying error message in my linux box by commenting out the first line (i.e., "NameVirtualHost: *:80" ) in "/etc/apache2/ports.conf":

Install NumPy & SciPy with ATLAS from source on SUSE Linux 10.1
Yesterday I finally installed NumPy/SciPy with ATLAS from source on SUSE Linux 10.1 (X86_64) to "$HOME/local" directory. Here is the summary of procedures (based on the instructions from SciPy home page with some modifications).
Install required packages
Python "nose" packages
swig-1.3.40
Build ATLAS with lapack (3.1.1)
Basically I followed the example instructions from ATLAS home page. Below are the key resulting options for lapack and ATLAS:
LAPCAK
The LAPACK root directory is "/users/kks/toos/lapack-3.2.1-patched" where I modified "make.inc" as follows:
Then typing "make lib" results in the LAPACK library "lapack_LINUX.a" there.
ATLAS
The ATLAS root directory is "/users/kks/tools/ATLAS" and its build directory is "/users/kks/tools/mybuild/atlas". In the "atlas" directoy, I built ATLAS as follows:
Then I followed these steps in the "lib" directory under the build directory to build a full LAPACK library (static one, i.e., "liblapack.a"):
Still, the shared version (i.e., "liblapack.so") is missing. So I convereted the static library to a shared one as follows (based on this suggestion):
Now we have both static and shared versions of full LAPACK libraries based on ATLAS!
Build UMFPACK (5.4.0)
As said, I followed basically the same procedures outlined here with the following "UFconfig.mk" settings (note that "CFLAGS" appear twice):
Build FFTW (3.2.2)
I didn't try these, but one may add the following additional options for "configure":
Build Numpy and Scipy (development version)
Unlike the said instructions, I didn't create "site.cfg" files, but simply did the following to install both the packages:
That's it!

To-do for research this week
- Understand the basic operation of network device drivers and routing/bridging processes in order to implement network simulation models that are more independent of simulators. Specifically, the following will be investigated:
- How IRQs and their handlers are related with event handlers in discrete-event-driven simulators;
- How timers can be implemented in simulators such a way that details specific to simulators are hidden from the models.
- Start working on building new simulation models for hybrid TDM/WDM-PONs based on existing SUCCESS models and OMNeT++ 4.x release.
- Study the concurrent programming and languages better supporting this framework including Erlang, scalar, and clojure.

Caroline Kennedy's endorsement of Obama
Caroline put it correctly here in New York Times on who should be a next president and a leader of not only US but also the world:

A President Like My Father
By CAROLINE KENNEDY
OVER the years, I’ve been deeply moved by the people who’ve told me they wished they could feel inspired and hopeful about America the way people did when my father was president. This sense is even more profound today. That is why I am supporting a presidential candidate in the Democratic primaries, Barack Obama.
My reasons are patriotic, political and personal, and the three are intertwined. All my life, people have told me that my father changed their lives, that they got involved in public service or politics because he asked them to. And the generation he inspired has passed that spirit on to its children. I meet young people who were born long after John F. Kennedy was president, yet who ask me how to live out his ideals.
Sometimes it takes a while to recognize that someone has a special ability to get us to believe in ourselves, to tie that belief to our highest ideals and imagine that together we can do great things. In those rare moments, when such a person comes along, we need to put aside our plans and reach for what we know is possible.
We have that kind of opportunity with Senator Obama. It isn’t that the other candidates are not experienced or knowledgeable. But this year, that may not be enough. We need a change in the leadership of this country — just as we did in 1960.
Most of us would prefer to base our voting decision on policy differences. However, the candidates’ goals are similar. They have all laid out detailed plans on everything from strengthening our middle class to investing in early childhood education. So qualities of leadership, character and judgment play a larger role than usual.
Senator Obama has demonstrated these qualities throughout his more than two decades of public service, not just in the United States Senate but in Illinois, where he helped turn around struggling communities, taught constitutional law and was an elected state official for eight years. And Senator Obama is showing the same qualities today. He has built a movement that is changing the face of politics in this country, and he has demonstrated a special gift for inspiring young people — known for a willingness to volunteer, but an aversion to politics — to become engaged in the political process.
I have spent the past five years working in the New York City public schools and have three teenage children of my own. There is a generation coming of age that is hopeful, hard-working, innovative and imaginative. But too many of them are also hopeless, defeated and disengaged. As parents, we have a responsibility to help our children to believe in themselves and in their power to shape their future. Senator Obama is inspiring my children, my parents’ grandchildren, with that sense of possibility.
Senator Obama is running a dignified and honest campaign. He has spoken eloquently about the role of faith in his life, and opened a window into his character in two compelling books. And when it comes to judgment, Barack Obama made the right call on the most important issue of our time by opposing the war in Iraq from the beginning.
I want a president who understands that his responsibility is to articulate a vision and encourage others to achieve it; who holds himself, and those around him, to the highest ethical standards; who appeals to the hopes of those who still believe in the American Dream, and those around the world who still believe in the American ideal; and who can lift our spirits, and make us believe again that our country needs every one of us to get involved.
I have never had a president who inspired me the way people tell me that my father inspired them. But for the first time, I believe I have found the man who could be that president — not just for me, but for a new generation of Americans.
The reason to believe again
Here is the living example of the reason to believe again, which reminds me of much of Lincoln's great speeches.
Barack Obama's victory speech in South Carolina (from his campaign web site):
Text as prepared for delivery...
Over two weeks ago, we saw the people of Iowa proclaim that our time for change has come. But there were those who doubted this country’s desire for something new – who said Iowa was a fluke not to be repeated again.
Well, tonight, the cynics who believed that what began in the snows of Iowa was just an illusion were told a different story by the good people of South Carolina.
After four great contests in every corner of this country, we have the most votes, the most delegates, and the most diverse coalition of Americans we’ve seen in a long, long time.
They are young and old; rich and poor. They are black and white; Latino and Asian. They are Democrats from Des Moines and Independents from Concord; Republicans from rural Nevada and young people across this country who’ve never had a reason to participate until now. And in nine days, nearly half the nation will have the chance to join us in saying that we are tired of business-as-usual in Washington, we are hungry for change, and we are ready to believe again
But if there’s anything we’ve been reminded of since Iowa, it’s that the kind of change we seek will not come easy. Partly because we have fine candidates in the field – fierce competitors, worthy of respect. And as contentious as this campaign may get, we have to remember that this is a contest for the Democratic nomination, and that all of us share an abiding desire to end the disastrous policies of the current administration.
But there are real differences between the candidates. We are looking for more than just a change of party in the White House. We’re looking to fundamentally change the status quo in Washington – a status quo that extends beyond any particular party. And right now, that status quo is fighting back with everything it’s got; with the same old tactics that divide and distract us from solving the problems people face, whether those problems are health care they can’t afford or a mortgage they cannot pay.
So this will not be easy. Make no mistake about what we’re up against.
We are up against the belief that it’s ok for lobbyists to dominate our government – that they are just part of the system in Washington. But we know that the undue influence of lobbyists is part of the problem, and this election is our chance to say that we’re not going to let them stand in our way anymore.
We are up against the conventional thinking that says your ability to lead as President comes from longevity in Washington or proximity to the White House. But we know that real leadership is about candor, and judgment, and the ability to rally Americans from all walks of life around a common purpose – a higher purpose.
We are up against decades of bitter partisanship that cause politicians to demonize their opponents instead of coming together to make college affordable or energy cleaner; it’s the kind of partisanship where you’re not even allowed to say that a Republican had an idea – even if it’s one you never agreed with. That kind of politics is bad for our party, it’s bad for our country, and this is our chance to end it once and for all.
We are up against the idea that it’s acceptable to say anything and do anything to win an election. We know that this is exactly what’s wrong with our politics; this is why people don’t believe what their leaders say anymore; this is why they tune out. And this election is our chance to give the American people a reason to believe again.
And what we’ve seen in these last weeks is that we’re also up against forces that are not the fault of any one campaign, but feed the habits that prevent us from being who we want to be as a nation. It’s the politics that uses religion as a wedge, and patriotism as a bludgeon. A politics that tells us that we have to think, act, and even vote within the confines of the categories that supposedly define us. The assumption that young people are apathetic. The assumption that Republicans won’t cross over. The assumption that the wealthy care nothing for the poor, and that the poor don’t vote. The assumption that African-Americans can’t support the white candidate; whites can’t support the African-American candidate; blacks and Latinos can’t come together.
But we are here tonight to say that this is not the America we believe in. I did not travel around this state over the last year and see a white South Carolina or a black South Carolina. I saw South Carolina. I saw crumbling schools that are stealing the future of black children and white children. I saw shuttered mills and homes for sale that once belonged to Americans from all walks of life, and men and women of every color and creed who serve together, and fight together, and bleed together under the same proud flag. I saw what America is, and I believe in what this country can be.
That is the country I see. That is the country you see. But now it is up to us to help the entire nation embrace this vision. Because in the end, we are not just up against the ingrained and destructive habits of Washington, we are also struggling against our own doubts, our own fears, and our own cynicism. The change we seek has always required great struggle and sacrifice. And so this is a battle in our own hearts and minds about what kind of country we want and how hard we’re willing to work for it.
So let me remind you tonight that change will not be easy. That change will take time. There will be setbacks, and false starts, and sometimes we will make mistakes. But as hard as it may seem, we cannot lose hope. Because there are people all across this country who are counting us; who can’t afford another four years without health care or good schools or decent wages because our leaders couldn’t come together and get it done.
Theirs are the stories and voices we carry on from South Carolina.
The mother who can’t get Medicaid to cover all the needs of her sick child – she needs us to pass a health care plan that cuts costs and makes health care available and affordable for every single American.
The teacher who works another shift at Dunkin Donuts after school just to make ends meet – she needs us to reform our education system so that she gets better pay, and more support, and her students get the resources they need to achieve their dreams.
The Maytag worker who is now competing with his own teenager for a $7-an-hour job at Wal-Mart because the factory he gave his life to shut its doors – he needs us to stop giving tax breaks to companies that ship our jobs overseas and start putting them in the pockets of working Americans who deserve it. And struggling homeowners. And seniors who should retire with dignity and respect.
The woman who told me that she hasn’t been able to breathe since the day her nephew left for Iraq, or the soldier who doesn’t know his child because he’s on his third or fourth tour of duty – they need us to come together and put an end to a war that should’ve never been authorized and never been waged.
The choice in this election is not between regions or religions or genders. It’s not about rich versus poor; young versus old; and it is not about black versus white.
It’s about the past versus the future.
It’s about whether we settle for the same divisions and distractions and drama that passes for politics today, or whether we reach for a politics of common sense, and innovation – a shared sacrifice and shared prosperity.
There are those who will continue to tell us we cannot do this. That we cannot have what we long for. That we are peddling false hopes.
But here’s what I know. I know that when people say we can’t overcome all the big money and influence in Washington, I think of the elderly woman who sent me a contribution the other day – an envelope that had a money order for $3.01 along with a verse of scripture tucked inside. So don’t tell us change isn’t possible.
When I hear the cynical talk that blacks and whites and Latinos can’t join together and work together, I’m reminded of the Latino brothers and sisters I organized with, and stood with, and fought with side by side for jobs and justice on the streets of Chicago. So don’t tell us change can’t happen.
When I hear that we’ll never overcome the racial divide in our politics, I think about that Republican woman who used to work for Strom Thurmond, who’s now devoted to educating inner-city children and who went out onto the streets of South Carolina and knocked on doors for this campaign. Don’t tell me we can’t change.
Yes we can change.
Yes we can heal this nation.
Yes we can seize our future.
And as we leave this state with a new wind at our backs, and take this journey across the country we love with the message we’ve carried from the plains of Iowa to the hills of New Hampshire; from the Nevada desert to the South Carolina coast; the same message we had when we were up and when we were down – that out of many, we are one; that while we breathe, we hope; and where we are met with cynicism, and doubt, and those who tell us that we can’t, we will respond with that timeless creed that sums up the spirit of a people in three simple words:
Yes. We. Can.
