Kid motivation

Who needs more motivation: kids or parents? When we’re in the parenting role, we spend so much time on yes and no, dos and don’ts, that we think our kids are never properly motivated. Once we have an adult system for keeping everything ordered in life, we expect that our children will follow suit as soon as they can understand.

But what if kids are there more to motivate the parents than the other way around? Don’t get me wrong; all kids need structure and discipline, but maybe it’s too easy to consider ourselves superior and miss some of our own lessons. Doesn’t it seem that in some respects, parents learn more about life, love, and moral character when raising kids than at any other time?

And they were bringing children to him that he might touch them, and the disciples rebuked them. But when Jesus saw it, he was indignant and said to them, “Let the children come to me; do not hinder them, for to such belongs the kingdom of God.  Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.” And he took them in his arms and blessed them, laying his hands on them. – Mark 10:13-16

Let’s never forget that everyone who touches our lives is a unique soul who is working for God’s ultimate purpose. We spend so much time complaining about the difficulties we have with other people or raising our kids when we should be watching and listening for that still small voice. I think that raising children is the best example of how giving up everything we know can reap rewards beyond our imagination. Plan from your head but walk with God in your heart.

Baby politics

There’s been a lot of noise lately in the media about what I might call “baby politics.” There’s been debate about whether abortion coverage should be required by the federal government to be in our health insurance; about who should pay for that coverage, and whether some groups can get an exemption.

The intensity of the emotions on this topic has always been huge, and understandably so. Is abortion a basic human right or an atrocity? South Africa actually has a constitutional provision that protects the right to abortion, though the word abortion never appears directly:

Everyone has the right to bodily and psychological integrity, which includes the right to make decisions concerning reproduction…

Everyone has the right to have access to health care services, including reproductive health care – http://www.info.gov.za/documents/constitution/1996/96cons2.htm

The wording is interesting to me: “reproductive health care.” Look at the dictionary definitions of these words:

  • reproductive: serving to reproduce
  • health: the general condition of the body or mind with reference to soundness and vigor
  • care: protection; charge: He is under the care of a doctor

The naive person might read this sentence and think that pregnant mothers have the right to doctors who will help them bring their babies to full term and a healthy delivery. In reality, this means that a pregnant mother can elect to have her fetus terminated, even if there is no medical health reason for the mother to do so.

Now that I am a proud father of a one-year-old baby boy, I see things through a different lens. Each child brought into this world has an unimaginable amount of potential, and will impact his parents and others for years to come. I imagine that for most parents, raising a child will uproot their life as they know it, shuffle their priorities, and drive a greater moral sensitivity.

I can’t help but wonder about the staunchly pro-choice advocates; how many of them have raised children? It certainly seems much easier to dismiss an unborn child as a soulless, mindless, and purposeless non-person before you raise a child from its infancy. Now I cannot help but cry when I hear stories such as the Philadelphia abortion doctor who was killing the babies that survived the abortion procedure by cutting the spine with scissors.

According to a medical paper on elective abortion, 40% of all American women will have an abortion throughout their lives. This amounts to 1.3 million abortions per year; this is more than one third the rate of the live birth rate. If these unborn babies have any value whatsoever, is this anything but a terrible tragedy that we repeat year after year?

In summary, all I can say is that I sincerely hope and pray that anyone contemplating aborting their unborn child would consider the positive impact this child will have on your life and on others. It’s not like throwing away a broken or unwanted toy; there are a lot of women out there who would give anything to take that choice back, because it’s a decision they have to live with the rest of their lives.

I’m sure that most people considering abortion feel either grossly unprepared, indadequate, humiliated, or divided between the unborn child and their lover, but remember that the love and joy that will follow will exceed everything else. And to those who have undergone an abortion themselves, remember that we have a God who cares about us more than we care about ourselves, and He will forgive our sins and cleanse us from all unrighteousness if we can only ask for forgiveness.

Above all, keep loving one another earnestly, since love covers a multitude of sins. – 1 Peter 4:8

Rejoice in the Lord always; again I will say, rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. – Philippians 4:4-7

I’ve recently started using Fedora 16 on my laptop computer, and I enabled the avahi service, which uses mDNS, more commonly known as Bonjour in Apple terminology. This is a convenient way for devices on a small network to automatically discover each other; I enabled avahi on my desktop computer and the two machines found each other’s IP addresses. It’s also used by my HP 6940 desktop printer, which it automatically discovered.

Unfortunately, mdns started getting flaky recenty, and then stopped working altogether in the last couple days. I spent quite awhile looking for Linux problems. The odd thing was that avahi worked fine over the ethernet cable, just not over wireless. After some troubleshooting, I discovered that my wireless interface was not sending or receiving any multicast traffic, which is how mdns works. Eventually I discovered that my wireless access point, an Actiontec MI424-WR rev C, which Verizon provided when they setup FiOs, has issues with wireless multicast. The most common complaint I found is with Bonjour not working:

Despite a number of claims from companies like HP saying that Actiontec routers don’t support Bonjour, I finally found a configuration setting that fixed the problem. Under the web configuration for the router, go to Advanced -> IGMP Proxy -> ACL Multicast Filtering. In my case I enabled the whitelist, then added my particular IP of interest: 224.0.0.251 / 255.255.255.255, which is what mDNS / Bonjour use. Apparently everything is filtered by default, though I wonder if this is a recent change from Verizon in their firmware configuration. Once I added my whitelist entry and saved, multicast started working instantly.

In Linux, this is obvious by running “avahi-browse -at” and looking for expected results beyond localhost. My mDNS / Bonjour printing also started working.

Another thing to check is that Multicast is not disabled at some other level; check the Interface Multicast Filtering to make sure that all interfaces are enabled.

I wanted to post this in case anyone else experienced the same problems.

I have been running Fedora 16 on two different computers at home for the last couple months, and everything seemed to be working fine until about a week ago. A few websites became unresponsive through Firefox after a few clicks, and behaved as if the server was down. This happened with expedia.com and continental.com.

After awhile I tried clearing my cookies, and then the websites loaded up again. But after navigating through the sites for a few minutes, they would stop working. The strange thing was that running wget or elinks on the same URLs would work fine. The same behaviour occurred on my Fedora desktop and laptop, and on Firefox, Chrome and Opera. When I booted my laptop back into Windows Vista, it worked fine! I even tried an Ubuntu 10.04 LTS live CD, and it had the same problems as Fedora 16.

After doing some analysis with tcpdump and wireshark, I found that the initial HTTP GET request was large enough to span two ethernet frames due to the submission of cookies. The first frame was never acknowledged by the server; in fact, there was no response at all. In wireshark I would see several TCP retransmissions from the client side but no response. When no cookies are present, the initial GET request is very small and so there is only one frame.

So to make a long story short (too late), the problem was that certain websites were failing with the default 1500 MTU size used by Linux. When I examined the IP addresses of the problematic servers, the common thread seemed to be the use of akamai servers: expedia.com, continental.com, and redbox.com. The max MTU I could use was 1488, which seems to work perfectly.

I was curious about why Windows was working and not Linux. First of all, my wireless connection in Vista was using an apparent registry-specified MTU of 1300, which would not have the problem. Secondly, even with an MTU set to 1500, looking at wireshark traces on Windows Vista, it appears that Windows has some sort of automatic shrinking of the MTU if it gets no response. I know the proper thing to do with Path MTU Discovery is to wait for an ICMP error, but that wasn’t happening. Apparently the Linux network stack just retries without shrinking, whereas Windows eventually figured out to use a smaller MTU. In some traces it was down to 576, and in others it used 1488.

Perhaps the strangest thing about this issue was that the aforementioned websites were working fine for me one or two months ago. There must have been some inadvertent change on akamai’s servers, or some combination of akamai and Verizon. I connect to the Internet via Verizon FiOs. My Actiontek router is set to MTU auto and seems to support MTU 1500.

In any case, hopefully this will save someone else some troubleshooting time. The combination of the Linux network stack, certain webservers, and perhaps my ISP have caused this problem.

Merry Christmas!

Merry Christmas to everyone! And remember that it is merry because we celebrate the birth of the savior, the king, and one who came not just for the lost sheep of Israel, but also for the gentiles. Jesus came into this world to save all mankind.

Most people think that they don’t need to be saved; I suppose we all think we can take care of ourselves for the most part. Just ponder for a moment all the weaknesses you have. We each fall victim to our own whims at least occasionally, even when we know it’s wrong. The question is how do we hold ourselves accountable to a higher standard and avoid the gradual moral decay throughout our lifetime? Only through God’s grace. And God’s grace was most fully manifested in one man, the Word made flesh, Jesus Christ of Nazareth, born in Bethlehem as foretold hundreds of years prior. The prince of peace. The one who would ultimately be pierced for our transgressions.

Do you seek righteousness in the world but find yourself disappointed? Do you seek truth, honesty, and love within yourself? Do you strive to make the best choices in life but find yourself always disappointed? Certainly this truth is not the way of the world, but it can be found in the Word. Try it. Listen to the words of Jesus and consider carefully whether you think these words are divine or derived, inspired or irritating, selfless or selfish. Then ask yourself: what if there is a God who cares about us, and what if the greatest mystery is not some hidden spell from a Harry Potter novel, and what if we already have the mystery and revelation of his love?

And when Elizabeth heard the greeting of Mary, the baby leaped in her womb. And Elizabeth was filled with the Holy Spirit, and she exclaimed with a loud cry, “Blessed are you among women, and blessed is the fruit of your womb!” – Luke 1:41-42 (ESV)

Hallelujah, our savior lives! Amen.

Gnome3

I finally upgraded from Fedora 13 to the latest and greatest Fedora 16 version of Linux on my home desktop, which includes the very controversial Gnome 3. I have to say that despite all the complaints, I have really taken to the new window manager.

The things that are most noticably missing: minimize button, maximize button, task bar on the bottom of the screen, desktop icons, and Applications menu. However, after some time with it you realize you don’t really need to minimize, you can maximize by double clicking, and desktop icons are a waste of space because you can never get to them.

The quick launch bar is Mac-ish, but it’s on the left, and it only appears when you open the Activities overlay by hovering the mouse in the top-left or clicking Activities. This is great because you really maximize available screen space.

And the best part is that task switching is much nicer than any window manager I’ve used. Alt-tab opens up a list of large icons grouped by app, and you can hover on the app to see all its child windows; very intuitive with the mouse. Plus the Activities overlay lays out a shrunken version of each open window on the screen to select. Now you don’t have as much need for multiple workspaces, but even if do, the task switchers make it seamless.

Very nice.

Christian Capitalism

Capitalism is a funny topic. In a world where we try to place every person and idea into carefully crafted boxes, capitalism has always had its detractors. Historically it seems that capitalism has been seen as a Judeo-Christian concept, and has always been played against communism and “social justice.” However, the more I started exploring the scriptures, the more I questioned this theory.

One quote that is sometimes falsely attributed to Jesus is, “Give a man a fish and feed him for a day, but teach him to fish and feed him for a lifetime.” This is apparently an old Chinese proverb. However, there are certainly a great many proverbs from the Old Testament that emphasize personal responsibility:

Diligent hands will rule, but laziness ends in slave labor. – Proverbs 12:24

All hard work brings a profit, but mere talk leads only to poverty. – Proverbs 14:23

The way of the sluggard is blocked with thorns, but the path of the upright is a highway. – Proverbs 15:19

Here is a New Testament quote about laziness:

…For even when we were with you, we gave you this rule: “If a man will not work, he shall not eat.”

We hear that some among you are idle. They are not busy; they are busybodies. Such people we command and urge in the Lord Jesus Christ to settle down and earn the bread they eat. – 2 Thessalonians 3:10-12

Certainly I would think that the Christian founders of this country were all dedicated to hard work and self-sustenance, otherwise they would not have risked the journey, nor survived. Perhaps we sometimes associate Christianity with free enterprise because the two were so closely intertwined, and both required much perseverance for those fleeing persecution in Europe.

As for the kind of unbridled greed that has become associated with capitalism today, I hope any Christian would realize that this corruption is completely un-biblical. Even the brand of capitalism toted by the atheist Ayn Rand is decidedly ungodly; after all, in the introduction to The Fountainhead, she labels her philosophy as “man worship,” which directly contradicts the Judeo-Christian faith to the core.

Even in the pragmatic Book of Proverbs, more verses seem devoted to kindness, righteousness, humility, and honesty:

From the fruit of his lips a man is filled with good things as surely as the work of his hands rewards him. – Proverbs 12:14

No harm befalls the righteous, but the wicked have their fill of trouble. – Proverbs 12:21

Righteousness guards the man of integrity, but wickedness overthrows the sinner. – Proverbs 13:6

Misfortune pursues the sinner, but prosperity is the reward of the righteous. – Proverbs 13:21

A poor man’s field may produce abundant food, but injustice sweeps it away. – Proverbs 13:23

The Lord tears down the proud man’s house but he keeps the widow’s boundaries intact. – Proverbs 15:25

Clearly, the biblical view is that God expects us to work diligently on whatever we are called to do, but the outcome of our effort is always up to God. We can easily bring a lifetime of work to ruin in mere moments with unwise words and decisions, as we watch so many times in the media; however, even the “just” and the “righteous” have their times of trial, such as Job and the apostles.

Jesus speaks about money in some of his parables, and it would seem that he argues both sides of the works / grace dichotomy. He speaks about the flat-rate payment plan of his vineyard workers, even though some people work far fewer hours than others:

“The workers who were hired about the eleventh hour came and each received a denarius. So when those came who were hired first, they expected to receive more. But each one of them also received a denarius. When they received it, they began to grumble against the landowner. ‘These men who were hired last worked only one hour,’ they said, ‘and you have made them equal to us who have borne the burden of the work and the heat of the day.’

“But he answered one of them, ‘Friend, I am not being unfair to you. Didn’t you agree to work for a denarius? Take your pay and go. I want to give the man who was hired last the same as I gave you. Don’t I have the right to do what I want with my own money? Or are you envious because I am generous?’

“So the last will be first, and the first will be last.” – Matthew 20:9-16

The payment schedule mentioned above would seem more on the “social justice” side than on the capitalism side, would it not? Here he is speaking about the grace of God: many people will not repent until very late in life, doing much less “work” for the gospel, yet they will inherit the kingdom of heaven just as readily as those who struggle in the faith all their life.

But what about the parable of the ten minas, where the one with the most receives the portion of the one with the least?

“Then another servant came and said, ‘Sir, here is your mina; I have kept it laid away in a piece of cloth. I was afraid of you, because you are a hard man. You take out what you did not put in and reap what you did not sow.’

“His master replied, ‘I will judge you by your own words, you wicked servant! You knew, did you, that I am a hard man, taking out what I did not put in, and reaping what I did not sow? Why then didn’t you put my money on deposit, so that when I came back, I could have collected it with interest?’

“Then he said to those standing by, ‘Take his mina away from him and give it to the one who has ten minas.’

” ‘Sir,’ they said, ‘he already has ten!’

“He replied, ‘I tell you that to everyone who has, more will be given, but as for the one who has nothing, even what he has will be taken away. But those enemies of mine who did not want me to be king over them—bring them here and kill them in front of me.” – Luke 19:20-27

At first I was unclear what the minas stood for. But after reading commentary I realized I had missed the beginning of the parable, where he spoke about the master going away to a “distant country,” which meant he wouldn’t be back for a while. This is clearly a reference to the spiritual gifts and the Word that God has left with us before the final judgment. The servants are the believers, the stewards of the church, and he’s not talking about money.

There are so many biblical analogies to the “fruit” of the believers, and it is with his spiritual gifts that he will expect the greatest productivity. Thus, perhaps we are to work hardest at serving God: serving others, sharing the gospel, comforting the afflicted, loving one another, and praising God.

I look at capitalism as a great innovation that, when combined with the freedom for people to find their own vocation, allows for great productivity and financial blessings for the vast majority of the participants. However, it is still a gift from God, and must always remain secondary to our commitment to His way. The more we discard Christianity for materialism and academic atheism, the more likely we are to be a fountain of corrupt capitalism.

In the words of our saviour:

“I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing. If anyone does not remain in me, he is like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. If you remain in me and my words remain in you, ask whatever you wish, and it will be given you. This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.” – John 15:5-8
