Thinking about making a post, or a series about stuff that I wish I was taught about C in school.

I might just do it regardless of interest, it would be nice to just get my thoughts written down somewhere.

Also feel free to give me some topic suggestions, like bitwise operations, memory management, object oriented-ness, fun with undefined behaviors, advanced(?) topics, etc...

26 Strong Alternatives to Google Analytics to Explore

Google Analytics is a popular tool. It helps track and analyze how customers behave online. It gives a lot of data about website and app traffic. Some businesses choose other tools instead of Google Analytics. This is because Google Analytics is better for companies selling to consumers (B2C). It may not fit the needs of businesses selling to other businesses (B2B). Luckily, there are many…

Dear Diary,

Today I encountered a mysterious deer lady who follows me around and calls herself the Shadoe. I also met Tessa, the only other deer in all of Heap. I suspect the two may be related.

Chapter 31

31:1-2 Laban and his sons are frustrated at Jacob. They say that he took what was Laban's and that Jacob's wealth was all derived from Laban.

31:3 The Lord speaks to Jacob, telling him to return to his father's land and that "I will be with you."

31:4-9 Jacob calls Rachel and Leah that they are going to leave. He then continues that Laban has "deceived me and changed my wages ten times with respect to the male lambs." Jacob states since God is with him, no matter if Laban picked Jacob to have speckled or clean cattle, God would have multiplied just that demographic of cattle. Because of this, Jacob believes that all of Laban's cattle was given to Jacob by God.

31:10-13 Jacob speaks of a dream where the "Angel of the Lord" speaks to him. The Angel states He has seen the times when Laban has done wrong to Jacob. The Angel continues, telling Jacob to return to his homeland.

31:14-16 Both Rachel and Leah are supportive in Jacob's decision to leave. They state their distaste in their father by how they "were sold" and they hold no inheritance in their father's house. They also state the wealth Laban has taken has in time returned back to them and their children.

31:17-21 Jacob set his wives and children to leave with his livestock and possessions to go to Isaac's house. Before they leave, Rachel steals Laban's idols. Jacob had not told Laban about his intention of leaving, so they fled with what they had.

31:22-23 Laban was told Jacob left after 3 days, then Laban and his brethren went after him for 7 days and overtook him.

31:24 Laban has a dream where God tells him not to speak anything negative or evil to Jacob.

31:25-30 Laban confronts Jacob stating that Laban would have let Jacob leave with open arms and smiles then continues to ask why Jacob stole everything, including his gods.

31:31-32 Jacob replies that he was afraid that Laban would take everything away then continues saying that whoever stole Laban's gods should not live in the presence of "our brethren."

31:33-35 Laban searched all of Jacob and the party's possessions for the idols. Rachel hid the idols on the camel's saddle then sat on it. She then told Laban that she was on her period which was why she could not get up.

31:36-42 Jacob rebukes Laban and unloads pent-up anger. Jacob recounts the last 20 years and how unjust Laban has treated him. Jacob ends his rant by stating that if it wasn't for the fear of the God of Abraham and the fear of his father Isaac, Laban would have sent him away empty-handed.

31:43-44 Laban proposes to make a covenant with Jacob. Jacob announces God as the witness.

31:45-47 Jacob and party made a pillar and a heap of rocks they ate and drank on. Laban and Jacob used this heap to bear witness to their coming covenant but used different names. Jacob used "Witness Heap," Laban used, "Heap of Testimony."

31:48-52 The final name of the place was called, "This-Heap-Witnesses" and "The Vision." The covenant between Laban and Jacob is that as long as Jacob does not harm Laban's daughters or gets another wife, neither of them shall pass the landmark of the pillar and heap for harm to the other individual.

31:53-54 The covenant is made by the God of Abraham and the God of Nahor being judges. Jacob swore by the fear of Isaac and then offered a sacrifice on the mountain.

Other Remarks:

Laban and his son's claims are true, but the terms Jacob took were all discussed and agreed upon. The group must be frustrated that Jacob is doing better than Laban and his sons, not that a deal has gone sour. The group cannot say that Jacob has stole from Laban. (v.1-2) (read next point for revision)

Just realized that in the last part of chapter 30, Jacob isolates the spotless rams and only offers the female sheep the spotted ram. This makes all offspring from every female sheep spotted. I was under the impression that Jacob and Laban had separated the spotted and clean cattle right at the time of the agreement but the cattle were not to be separated until the time of Jacob's departure. So in a sense, Jacob did manipulate his deal with Laban, the deal did go sour. (v.1-2)

When God says "I will be with you," it is a message of protection, especially when Jacob is faced with many individuals who despise him, all being family. (v.3)

The Angel of the Lord is capitalized, indicating that He is the pre-human form of Jesus. This can also be inferred by the phrasing of the Angel's words. The Angel clearly says "I will be with you," indicating God's protection, indicating the Angel makes the claim of God. Another interpretation is the Angel is simply saying that Jacob will be granted protection from an angellic being, but this claim falls short when considering the rest of the message; Angels do not act of their own volition but on God's orders. Thus it makes sense that God makes form of an Angel, stating that God has seen the wrongdoings of Laban, and then decides to take action. (v.11-13)

Jacob had told Laban that he wanted to return home the last chapter, more precisely Jacob said he wanted to establish his own home. However, Jacob did not disclose where or that he planned to go back to his own land. This is why Jacob had to flee, rather than openly leaving. (v.17-21)

Although Rachel undertakes the faith of Jacob, she still clings to the idols of false gods. Additionally, Rachel lies to her own father about the theft, this might be due to wanting the idols or to avoid the punishment of separation, or both. (v.35)

An interesting remark made by Jacob during his rant is that Laban feared the God of Abraham. This shows a sort of duality that Laban is living because he fears THE God but worships idols. (v.42)

Laban's reply in verse 43 illustrates that he does not view his actions as unjust. Laban says that everything is partly his possession: the daughters, sons, sheep, and everything he sees. He then continues by wanting to do something for them. By isolating this scene, it looks like an ungrateful son who is arguing with his father. In this context, Jacob would be the ungrateful son. (v.43)

Jacob creates a pillar which serves as an altar to God since he wanted God to serve as witness. This is reflected in Jacob's naming of the heap as "Witness Heap," because the name puts an emphasis on God, the witness. This contrasts the name that Laban put on the heap, "Heap of Testimony," because this name places an emphasis on the actions rather than the witness the rocks are supposed to represent. In various points of the Bible, we see people name landmarks, such as wells, according to a variety of bases. These bases include: action that happened, emotion felt, etc. (v.47)

Just a reminder that Nahor is the brother of Abraham (v.53).

Online sources say Jacob called the heap "Galeed" while Laban called the heap "Jegar-sahadutha." Both of these terms mean "witness heap," but "Galeed" is in Hebrew while "Jegar-sahadutha" is in Aramaic. (v.47)

The final name for the heap (This-Heap-Witnesses) was "Galeed." (v.48)

Questions:

When does Laban change Jacob's wages with the male lambs? I believe the only part of the story where Laban shorthand Jacob is the wedding of Leah vs Rachel. This must be a detail that is true in the story but not written down for conciseity. (v.7)

Why does Rachel steal Laban's idols? Does she still participate in the faith of her father? This action counters her decision to follow the God of Jacob's order. (v.19)

Things to Add to Prayer:

help us to not take spiteful action against those who wrong us, but rather let your judgement guide both us and them, like you have done with Jacob and Laban.

Mystery solved

I believe I've solved the mysterious/scary bug I blogged about yesterday.

Last week I tried to eliminate some repeated code by turning it into "inline" methods that return references to objects. I changed code like this (simplified for clarity):

float getForceX(jlong bodyVa) { Body *pBody = reinterpret_cast<Body *> (bodyVa); const Vec3& result = pBody->GetForce(); return vec3.GetX(); } float getForceY(jlong bodyVa) { Body *pBody = reinterpret_cast<Body *> (bodyVa); const Vec3& result = pBody->GetForce(); return vec3.GetY(); } float getForceZ(jlong bodyVa) { Body *pBody = reinterpret_cast<Body *> (bodyVa); const Vec3& result = pBody->GetForce(); return vec3.GetZ(); }

into code like this (also simplified):

inline const Vec3& getF(jlong bodyVa) { Body *pBody = reinterpret_cast<Body *> (bodyVa); const Vec3& result = pBody->GetForce(); return result; }

float getForceX(jlong bodyVa) { const Vec3& vec3 = getF(bodyVa); return vec3.GetX(); } float getForceY(jlong bodyVa) { const Vec3& vec3 = getF(bodyVa); return vec3.GetY(); } float getForceZ(jlong bodyVa) { const Vec3& vec3 = getF(bodyVa); return vec3.GetZ(); }

In the back of my mind, I assumed Body::GetForce() was returning a reference to a Vec3, so it made sense for getF() to do likewise. But in fact, Body::getForce() returns a copy of a Vec3. Because of this, the compiler allocated stack space for a copy, then returned a reference to that copy. But the copy is only live during execution of getF(). Once the function returns, the copy can (and does) get trashed.

The correct solution, I think, is for getF() to likewise return a copy:

inline static const Vec3 getF(jlong bodyVa) { Body *pBody = reinterpret_cast<Body *> (bodyVa); const Vec3 result = pBody->GetForce(); return result; }

Two little ampersands can make a big difference!

This bug illustrates a couple subtle differences between C++ and Java. In Java, objects are passed and returned by reference, never by copy, so the latter possibility didn't occur to me. Furthermore, Java objects live on a heap, not a stack; as long as a reference lives, objects don't get trashed. Upshot: I'm out of practice thinking about this sort of issue.

Part of what made the bug hard to find was that it only caused failures when optimization was turned on. For various reasons, most of my testing is done with optimization turned off.

I'm not 100% sure how compiler optimization surfaced this bug, but I have some ideas. I could disassemble the compiled code, but I'm not curious enough to do that today.

The interesting question is: how does one solve a bug like this? I wish I'd used some clever tools or techniques, which I could now recommend. In fact, I solved it by trial and error, and my only relevant advice is to be persistent.
